I. Introduction to Miva
Miva is a Multimode Interactive Voice Announcer designed and manufactured in

Australia to provide voice processing automation for many types of telephone systems.
Miva can be connected directly to Telstra exchange lines or PABX/Key System analog
extensions.
By using a combination of operational modes, Miva can provide a professional and

sophisticated “sound impression”, when your company telephone is answered.
A. Multi-Mode Capabilities
Miva is truly a multi functional product, and with current software, it can be easily
configured into any of the following modes. Often one or two of these modes are
used simultaneously such as automated attendant and DISA.
• Recorded Voice Announcer (RVA)

• Call queue announcer (CQA)
• Single or multi level Automated attendant (AA)
• Direct Inward Station Access (DISA)
• Interactive Voice Response Systems (IVR)
• Auto Dialler and special out dial facilities
• Emergency announcement facilities
• Music on Hold promotional message announcer
1. Recorded Voice Announcer (RVA) or Call

Queue Announcer
Miva RVA will automatically answer a ring on any of its lines

(simultaneously) and then play a pre-recorded message to the caller.
This message could be used for any number of message requirements,
such as “Welcome - all our operators are currently busy...”.
Revision 1.3b Page 1 Miva user manual

Once the message is announced, Miva hangs up the line. Or,
alternatively, when the message is complete, Miva can hookflash, dial
another number and transfer the caller.
RVA announcements can include:
• ACD call queue announcements (four or six wire E/M connection)

• Temporary emergency messages - easily reverted to original message
• Message billboards
• After hours messages on nightswitch extensions
• Transport timetables
• Change of address announcements
Voice messages are stored in digital memory and can be replayed

instantly. The caller will always hear the message start at the beginning
as there is no rewinding or repositioning as may be required with a tape
system.
The total message storage time for each line may be split into a maximum
of 9 separate Message Blocks. One of these Message Blocks is set as the
Active Message by the User Menu and this is the message that Miva will
play when a line rings.
The stored message is not lost when power is removed from Miva.
Recording new messages and setting configuration parameters are easily

done by following a simple voice prompted User Menu and entering keys
on a telephone hand set. This telephone may be connected locally or
remotely via a telephone extension or line.
A single Miva card will connect to two lines and will answer two callers
simultaneously. By adding more Miva cards to the rack frame, up to 28
lines can be answered by a single Miva system. Further expansion is
then possible by the addition of rack frames.

2. Automated Attendant (AA) and Direct Inward
Station Access (DISA)
This mode frees the operator from answering every call. Miva AA allows
your callers to select who they wish to talk to and to be connected,
without the need for an operator’s intervention. The caller always has the
option of being connected to the operator.
The callers are greeted with an announcement and a spoken directory is

given. The caller is prompted to press a single numeric digit (automated
attendant) for the required person or department, or a full extension
number (Direct Inward Station Access - DISA). Miva will hookflash the
PABX and transfer the call.
Example AA and DISA directory announced by Miva
“Thank you for calling Mivatech. You may be connected

automatically or wait for the operator. Please enter an extension
number or...
Press 1 for Accounts

2 for Sales or
3 for Technical Services
3. Music on Hold Announcer (MOH)
The MOH mode is ideal for providing advertising and company

information messages to your customers while they are waiting on hold.
The Miva message storage can be broken up into one to nine message
blocks per line. A line can be directly connected to the MOH port of the
PABX/Key System (no isolator box is required) and Miva will play up to
nine messages in rotation, providing music and information to inform your
callers while they wait. Music from an external source such as a CD

player can be ‘cycled’ with the message blocks to form an endless
promotion on hold system. (Note: This mode requires special software -
please contact your dealer or Miva Corporation for further details).
Typical MIVA PABX/ Key System Connection

II. Quickstart Installation
The following steps will have you working with Miva in the shortest possible time.
1. Unpack Miva and connect the supplied DC plug pack or an external DC

supply to the rear of Miva. A supply of 12 - 55 volts DC is required.
Current drain is approximately 80 mA per card at 12 volts and less than
60 mA at 55 volts.
2. Connect a telephone to the LOCAL socket on the front panel. The phone
must be set to tone dialling.
Caution: PABX/KEY SYSTEM or Exchange lines should never be

connected to the LOCAL phone socket.
3. Pick up the LOCAL phone and listen for the voice prompt asking you to
enter a PIN code. On a new single card system the default user level PIN
code for the two ports are:
To access LINE 1 dial *101#
To access LINE 2 dial *102#
4. On multi card systems the default PIN codes for each card follows this
pattern:
Card 1 LINE 1 *101#

Card 1 LINE 2 *102#
Card 2 LINE 1 *201#
Card 2 LINE 2 *202#

Card 3 LINE 1 *301#
Card 3 LINE 2 *302# Etc etc
5. If you enter the correct PIN number, you will hear the User Menu. Follow
the prompts to find your way around the menu.
Try pressing
1 then 1 to listen to message 1 or

1 then 2 to listen to message 2 or
6 to listen to the mode setting prompts
6. Connect an analog telephone extension or direct telephone line to LINE 1

and/or LINE 2 connectors. (For 4 or 6 wire E/M trunk circuits see section
VI - D - 2 titled Installation Guide of this manual)
7. Call the extension that MIVA is connected to and while the outgoing
message is playing press the correct PIN number. Remember the factory
default is *101# for Line 1 and *102# for Line 2 on Card 1. You will hear
the message stop and the User Menu will commence playing. This is an
example of remote access. All the functions available from the LOCAL
phone connector are available by remote access.
8. Having rung the Miva unit and entered the PIN code for the port you wish
to enter, you will be prompted by the User Menu. Follow these prompts to
record your message. When you’re finished recording and playing,
ensure that you press 0 and then 0 again to exit the User menu
and Miva will then hang up.

9. Now when the Miva answers a call, it will play the message you have
recorded. If Miva does not answer correctly, see the information on jumper
settings in section VIII - D.
A. Power Supply

connectors located on the Miva card. Each LINE
can be separately configured.

There are 2 Jumpers per line on each Miva card which must be set as follows:
• Std Telephone/Extension circuits = Both Jumpers in position BC

• Trunk circuits/E&M signalling = Both Jumpers in position AB
Miva is normally shipped in the default jumper setting of position BC. For
information on connecting to Trunk circuits see section VIII - D in this manual.
The line connection is via 6 pin, RJ12 style connectors on the Miva front panel.
The centre two pins are the two wire extension/telephone line pair. See Section
V1 - D Line Connection.
C. Local phone - Setup
The LOCAL phone can be used for option programming and recording new
voice messages. This phone must be set to dial using DTMF tones.
Connect this phone to the top RJ socket on the front panel, labelled LOCAL.

III. General Features and Concepts
A. Miva Card - Features
The Miva Card is a complete, stand alone two channel Multi-Mode Interactive
Voice Announcer. It does not need any other support cards. A single Miva card
will answer two lines independently and will provide announcements and
transfer functions for ACD queues, automated attendant, DISA, IVR and MOH
plus many other applications.
The Miva card will store its configuration and recorded messages for many years
without power being applied.
By connecting a standard DTMF (tone dialling) telephone to the

LOCAL phone connector, on the front panel, full configuration and
message recording is possible.
Red and Green LED’s show the status of each LINE of the Miva card.
See the table in Section VIII - A - 1 for a full description of the LED
states.
Messages may also be recorded by connecting a tape recorder to the

AUX IN socket. This recording is controlled from the LOCAL phone.
LINE 1 and LINE 2 connect to the normal telephone lines, Centel Plus
and Spectrum lines or PABX/Key System extensions. Miva plays the
recorded message to these Lines.

B. System Features
1. Local phone
The LOCAL phone is to be used for option programming and recording

new voice messages. This phone is the only method of gaining access to
a new system and will be extensively used by the installing engineer to
set most common options to suit the local installation.
Menu access is available from this phone and it can also be used for the
recording of voice messages. If recording a new message from a tape
recorder via the AUX socket, the LOCAL phone keypad is used to access
the menu.
2. Remote Access
Remote access to Miva is possible on lines that can be dialled by an

authorised user e.g. PABX/Key System extension or Exchange lines.
When a caller rings a Miva line or extension, the active message will play
to the line or extension. While the message is playing, a caller can enter
the PIN sequence and Miva will stop playing the message and switch to
the User Menu. At this point the same options are available as with the
LOCAL phone e.g. Record a new message.

C. Menu System and Engineer Access
The User Menu allows handy access to many commonly programmable

features of Miva. Engineering access is available through the RS-232 port
and requires a PC or laptop (direct or via a modem) to change certain
configuration settings.
Warning: Ensure that the Miva unit is properly isolated before
connecting a PC or laptop directly to the RS-232 port. If
the unit is not properly isolated then damage to your PC or
laptop can occur.
1. User Menu
The User menu will allow basic message control and the recording
of new messages.
Each Miva line has its own PIN code i.e. entry of the PIN code for
Miva line 1 allows menu operations to only effect line 1.
This allows different PIN codes to be given to individuals

responsible for their own message lines. They will only be able to
change their own messages i.e. Miva card 1, line 1 may be the
Music on Hold and promotional message, administered by the
Marketing Department, while Miva card 1, line 2 may be the queue
repeat message, “All our operators are busy.......”, administered by
the Office Manager.
2. Engineer Programming
The Engineer port allows configuration of various line interface

parameters and variables through the RS-232 program port.
Please see Section VII Engineer Configuration and Port settings.

3. PINs (Personal Identification Numbers)
PINs are used to identify Miva lines and line groups (if
programmed). User level PINs can only be changed via the RS-
232 port.
Each single card system has two default PIN numbers as shown
below.
USER MENU LINE 1 * 101 #

USER MENU LINE 2 * 102 #
Multiple card systems have pins commencing with the position the
card is plugged into the card frame. Ie card 4 line 2 is pin *402#
D. Message Blocks - Multiple Messages
An important feature of Miva is the concept of splitting the total line message
storage time of 75 seconds per line (factory standard) into a maximum of nine
message blocks. (Storgae can be upgraded from the standard 75 seconds to
either 375 or 675 seconds for the total message duration.) This allows a number
of pre-recorded messages to be stored for different occasions for replay on the
one line. At any time, any one of these message blocks can be made the
ACTIVE message. The Active Message is the message that is played by Miva to
the line when triggered. This allows easy switching between messages for
different situations, by the real time clock, e.g. day and night messages.
The number of Message blocks available and the time used for each Block is set
via the RS-232 port. If only one message block is set, the full message time of
75 seconds is available for this message. The maximum time that can be
allocated to any message on Rev 1.5 boards or less is 75 seconds.

E. Automated Attendant in Mode 1
When the mode is set to Automated Attendant 1 in the User Menu, and diversion
number zero has also been entered, Miva will hookflash and dial the diversion
number when the message is finished. See the diagram below.
This feature can be very useful in many situations where a pre answer message
is required before the caller is connected.
Normal RVA Mode
Message Plays Hang Up
Automated Attendant 1 - Hook flash transfer
Hookflash & Dial

Message Plays Transfer Number Hang Up
See the Section VII - A - 8 Command Settings for Hookflash Transfer delay
settings.
If other diversion numbers are entered, then Miva will work as a standard
Automated Attendant and wait for key presses to pass a caller through to the
designated number.
When working as a standard Auto Attendant the Miva card will respond to
selection keys pressed on the caller’s phone. These selection keys must first be
programmed into the Miva line via the user menu.
To program a simple 3 choice AA, try the following procedure:

Pickup the local phone or dial in remotely and dial the PIN, eg
*101# at the prompt (note PIN 101 is a factory default setting for line 1)
Listen to the user menu. If you require selection key 1 to divert to ext 234 type
51234#
to confirm your setting type
951 and listen for the number.

Repeat the above procedure for keys 2 and 3 by typing
52289# for diversion to ext 289 on caller pressing key 2

53267# for diversion to ext 267 on caller pressing key 3
For a DISA entry in the number range 300 to 399 (example) you will allocate key
3 for the first digit in the range. To program this type
53***# This means a DISA range starting with 3 and has 3 digits in
total (denoted by the *** entries.)
F. Auto Attendant in Mode 2
The Automated Attendant Mode 2 is a customised AA setup, which is

programmed specifically to a customers needs and specifications. The
customised Auto Attendant can provide multiple layered trees, special functions
and a great versatility than the standard Auto Attendant mode.
Contact your dealer or Miva on 1300 366 481 for details.

IV. User Menu - Local Or Remote
The User Menu allows basic “day to day” maintenance operations on the Miva lines.
You can enter the User Menu from either the LOCAL phone port or by dialling into a
Miva LINE connected to a PABX/Key System extension and entering the PIN while the
message is playing.

the User Menu, typing the # key will make it stop and commence from the beginning.
The # key also processes functions just previously selected.
Key 1 Play messages
Key 1 is the play key. If you wish to play a message press
11 to listen to message 1
12 to listen to message 2 etc
Key 2 Record messages
Key 2 is the record key. If you wish to record a message in a particular message block
press
21*<speak your message># to record into message 1

22*<speak your message># to record message 2 etc
New messages can be recorded from either the LOCAL phone, at Miva, or by dialling
into a Miva LINE connected to a PABX/Key System extension.
You should listen to the current message, to be sure it is the message that you wish to
change, as messages recorded over will be lost. If a message block is protected or
does not exist, Miva will not allow a recording to be made.
NOTE: Before recording a new message you must be sure which Message block you
wish to record a new message into.
Key 3 Setting the active message

Key 3 will set the active message to be played to the line when triggered by a ring or
E/M signal. If you wish to change the active message press
31 to set message 1 as the active message

32 to set message 2 as the active message etc
The Active Message is the Message Block (message) that will be played when Miva
answers a call.
The total message storage time (75, 375 or 675 seconds) may be split up into a
maximum of nine multiple message blocks. The number of blocks is set via the
Engineer port. You then must set which message block will be played as the active
message. This allows easy switching between messages for different situations e.g.
day and night messages. On entry into the User Menu (after PIN entry), the User Menu
will say which Message Block is active.
Key 4 Record message from the tape input (AUX)

Key 4 will allow you to record from a tape or external audio source. To record from tape
you must queue the message on the tape player and press
41* <press the play button># to record message 1 from tape

42* <press the play button># to record message 2 from tape
Messages can be recorded from a tape recorder or other audio source by connecting to
the AUX socket on the Miva front panel. A standard stereo cable with 3.5mm jack is
required for this purpose. Please see Section VIII - A - 2 for connection details.
Recording from the AUX port is identical to recording from a telephone except that you
use Key 4 from the User Menu.
Note there are two settings available through the Engineer port which will alter the way
messages are recorded via the AUX socket.
1. Audio can be monitored on the telephone plugged into the LOCAL socket while
recording.
2. Audio is muted from the LOCAL socket.
Note that in 1. above, the telephone microphone is also active and any noise in the
background will be recorded. A tape player with a monitor speaker or a telephone on
the local port with a mute key is recommended to avoid this problem.
Key 5 Set diversion and DISA transfer numbers

To set single key diversion numbers or DISA extension numbers press
51 234 # to set key 1 to transfer to extension 234

52 *** # to set a 3 digit DISA extension commencing with 2 (exts 200-
299 are valid)
50 9 # to set key 0 (or default transfer) to dial 9 (operator console)
Miva can be configured to transfer the caller to another number at the end of the
message, in RVA mode.
In AA mode up to ten single key diversion numbers (maximum of 22 digits) are used for
storing external and extension numbers to transfer callers to.

In DISA mode, direct extension numbers can be dialled from the caller’s phone to
directly access the number.
Miva diverts the caller by “hook flashing” the PABX/Key System (or exchange) and
dialling the number. When the number has been dialled, Miva connects the caller
through to the dialled number by hanging up the line. This is called ‘blind transfer’.
If the number is busy or does not answer the phone system should be programmed to
automatically divert the call to another destination. This will avoid creating a loop where
the caller is sent back to the Miva line..
When programming diversion numbers, a * key in the string of extension digits

introduces a two second pause. More than one * can be used for extended pauses.
If the diversion string consists of a series of * keys, Miva recognises this as DISA and
the number of * keys in the string is the total number of extension digits accepted from
the caller before diverting. The key under which this string is inserted becomes the first
digit in the transfer number.
That is, extension number in the range 200 to 299 will be programmed as follows
52***#
For AA and DISA modes the Transfer number set for Key 0 is the number that will be
dialled if no key is entered by the caller or an incorrect key/s is entered.
NOTE: The * key has two uses in the diversion number string. If the * key is used with
digits, it is seen as a two second pause. If it is used on its own, it signifies the number
of digits in a DISA string.
Key 6 Setting mode of operation

To set the mode you wish this Miva line to operate in press
61 for RVA which hangs up at the end of the message (also call queue announcer)
62 for Auto Attendant in mode one with a single level tree
63 for Auto Attendant in mode two with a customised tree

Key 7 Protecting messages
If you need to protect any message block from accidental erasing or over recording
press
71 to protect message 1
72 to protect message 2 etc
Any or all of the message blocks can be protected from accidental recording or erasing.
The message protection key 7 is a toggle function. Press 7 followed by the message
number and the protection is set on or off. If you use the message protection function
and you hear “message protected”, the protection has just been turned on for that
message, however if you use the message protection and do not hear “message
protected” then it has just been turned off for that message.
Key 8 Enable the real time clock

To enable or disable the real time clock from switching message press
81 to disable the clock

82 to enable the clock
Although the real time clock may be set and active message switching times may be
established, the actual switching of the messages by the clock can be enabled or
disabled through the User Menu.
The real time clock setting and switching times on a seven day basis is set via the
Engineer port. The enabling and disabling of the clock is set via the User Menu.
Key 9 Status check

This key will help you check some of the settings of Miva.

V. Special functions
A. Music on Hold Mode (MOH)
In MOH mode, one of the Miva lines can be connected to the MOH port of the
PABX/Key System. It can be programmed to continuously play a message
sequence to waiting callers by using the multiple message storage and external
music injected into the AUX IN port. NOTE the jumpers on this line must be set
to the ‘A’ position (4 wire E/M).

IN (MOH) input. This could be a CD player or music from any source. Usually
about 500 - 1,000 mV of signal is required.
B. Centel Plus and Spectrum

Miva is programmable to allow connection to Centel Plus and Spectrum lines
(these are some of Telstra’s exchange products). Both Centel Plus and
Spectrum allow Miva to divert calls to other PSTN destinations like mobile
phones and remote offices.
Contact your dealer or Miva for more details or assistance with programming.
C. Interactive Voice Response (IVR)

Miva has designed software that enables the Miva cards to be used as a very
reliable Interactive Voice Response System which has a computer database
interface. Please contact Miva sales on 1300 366 481 or email
info@miva.com.au for more information.
D. Auto Dialling
Various versions of auto dialler are available on the Miva card platform. Please
contact Miva sales on 1300 366 481 or email info@miva.com.au for more
information.
E. Specially triggered RVA

Please consult Miva for details on these applications. There are many ways the
Miva card can be configured. We produce customised firmware for many
specialised applications.
F. Grouping Miva Ports together

A Miva system can have ports that are grouped together so that changes to one
port will update the other ports in the group. This can be very useful for systems
that require the same messages and diversion keys on a number of ports.
Rather than having to update 6 individual ports, changes can be made on the
one port and will be copied across to all other ports in that group.
Note: The quality of the recorded messages on the slave ports will deteriorate
to some degree across a group copy.

VI. Installation Guide
A. Getting started
The following checklist should be followed for each installation
1. What mode will you use RVA o AA1 o AA2 o
2. What connection type 2W o 4W o 6W o
3. Set card jumper links 2W in BC 4W & 6W in AB
4. From Local phone access the User Menu by dialling the correct PIN ie *101#
5. Record messages and replay to verify. Use key 2.
6. Set active message. Use key 3.
7. Program diversion keys for auto attendant mode. Use key 5.
8. Playback diversion numbers. Use key 9.
9. Connect to PABX or KEY extensions or telephone lines and call to check

operation.

B. Miva Hardware
The Miva System consists of a number of components;
• The Rack or Case - available in three sizes accommodating a

maximum of 1, 7 or 14 Miva cards. The 7card size is a desktop or
chasseleon case while the 14 card size is a 19 inch rack unit. The 1
card case is a special stand-alone Miva case called Keyvoice.
• The Backplane provides expansion flexibility. Each backplane

connects 7 cards. By adding two back planes to a full 19 inch frame, 14
cards can be accommodated.
• The Miva card - 220mm deep 3U Euro card. The same card fits all
rack units.
C. Miva Card
The Miva card is a stand-alone announcer with all necessary circuitry included
on one PCB. The latest Surface Mount techniques are used to achieve the
circuit density necessary to contain all the required components on a single
220mm Euro Card and providing exceptional reliability.
The Miva card must be set for either 2 wire ring trip or 4 or 6 wire E & M
connection, by jumpers on the card. There are 2 jumpers for each line. One line
may be set for 2 wire while the other is set for E & M.
See Section VI - D and VIII-D for connection details.

D. Location - environment
Miva has no special environmental requirements. The normal location would be

in the PABX/Key System room adjacent to the PABX/Key System. This is for
practical cabling reasons.
Miva could also be used in an office, connected to a single PABX/Key System

extension or a direct exchange line.
E. Line Connection
The Miva front panel contains three RJ12 six pin telephone sockets. Line 1 and
Line 2 are the service lines for 2 wire or 4 or 6 wire E/M connection and Local is
for local programming from a touch phone or Buttinsky.

1. 2 Wire connection
For auto attendant and audio text operation the standard 2 wire telephone
pair is connected to pins 3 & 4. This is the PABX/Key System analogue
extension or the PSTN Exchange connection (a standard telephone line
from the local telephone exchange).

Miva will detect a ring signal on this pair and will loop it to answer the call.
Miva will then play the active message and then hang up. Optionally
Miva can hookflash and dial a diversion number.
2. Trunk and 4 and 6 wire E/M interfaces
Miva can be connected to the trunk circuit of a PABX/Key System . This is

the normal method of connecting an RVA to some PABX systems to
provide “Operator busy ......”, style call queue announcer messages.
The E & M leads are used for handshake signalling between the Miva and
the PABX/Key System and the connection type can vary depending on
the type of PABX/Key System.

Connection Connection
When connecting E/M circuits, care must be taken to be sure of the

terminology used. The same wire may be an E lead from the Miva end
and an M lead from the PABX/Key System end.

The Miva receives an active E lead as the start or message trigger signal
and sends an M signal to indicate that the message is playing or to
indicate an end of message signal. When the message is finished Miva
removes the active M lead. The E signal can be pulsed at different times
to indicate different functions.
The Miva polls the E lead and when the E lead goes high for the specified
length of time stored at address f27 (E lead trigger delay) then the Miva
will hold the M lead active and play the active message. If the E lead then
reverts to its idle state, the Miva will finish playing the active message and
release the M lead. However, if the E lead remains high for the length of
time stored at address f28 (pulse length for continuous message), then
the Miva will play the active message in what is known as continuous
mode.
Continuous mode will keep playing the message until the E lead reverts to
its idle state – at which point the Miva will instantly stop and release the M
lead. If the message finished while in continuous mode, the Miva will drop
the M lead momentarily, if the E lead stays active during this time, then
the Miva will raise the M lead again and repeat the message. This will
continue until the E lead becomes idle.
Note: A common problem that occurs when wiring an E & M connection is

that the circuit is not completed. Pins 5 and 6 need to be wired to the
battery and earth to complete the circuit.

3. Hookflash Transfer Settings
Auto attendant mode one requires that Miva be connected to a PABX/Key
System extension or a Centel Plus or Spectrum line that will accept this
mode of transferring calls (almost every PABX/Key System).
Miva must hookflash and dial with the correct timing between the
hookflash pulse and the start of dialling (called hookflash delay). The
default settings should be satisfactory in almost every case but if
hookflash transfer does not work, the settings may be adjusted via the
Engineer port.

VII. Engineer configuration port settings
This section describes various settings available via the RS-232 port.
CAUTION
FOR 48 VOLT DC BATTERY SYSTEMS
The -48 volt supply input connector on the Miva unit is not isolated
from the AUX IN and RS-232 (Engineering Port). If you plug a PC (or
laptop) into the Engineering port and the PC is grounded via the
mains cable, you may cause damage to the Miva card or the PC or
both. If in doubt, either purchase the PS-1 supply isolator option from
Miva or ensure all devices connecting to the Miva Engineering Port or
AUX IN or isolated from supply ground. Call 1300 366 481 for
assistance or email info@miva.com.au.
A. Port set up and configuring rules
1. Port set up - general
The serial port on Miva is the main method of changing configuration information. You
will need a 9 pin straight through serial lead to connect to your computer. The
communications program on your PC or laptop should be set to 9600 bps, 8 bits, 1 stop
bit, no flow control and no parity. Programs such as Telix, Procomm and Windows
Terminal may be used.
If the cards are in a rack frame, the left most slot looking from the front is card 1. The
cards are then sequentially numbered to the right. The card number must be specified
before all commands--if you leave it out or address a card that it not present, there will
be no response.
The cards are programmed by entering ASCII commands from your PC followed by the
ENTER key. All commands must be preceded by a card address number or the “all
card broadcast” number 0.
The address of ‘0’ is defined as an “all card broadcast” address, meaning that all the
cards will hear and respond to the command. This can be very useful for setting the
same information on a bank of cards. The responses will most likely be garbled due to
all the cards responding at the same time. For this reason, it is a good idea to check
that all the cards received the command properly by verifying the changed
configuration on each card after you have executed a broadcast command.

In the Keyvoice (card in a box) system, the card has an address of one. All commands
are case sensitive, some being upper and others lower case. Please read the notes on
the configuration table carefully. There are some undocumented commands--do not
attempt to find them as you are highly likely to change the Miva setup so that it will not
work as expected. If necessary, we will instruct you on the use of these commands.
Phone 1300 366 481 or email info@miva.com.au for help.
2. Port set up detail
Each Miva card has a serial RS-232 port consisting of 3 wires. Rx, Tx and Ground.
When the card is plugged into the Miva backplane, each port is multi dropped to a
common RS-232 connector for connection to a PC. In this situation, the technician must
exercise care to target the correct card or cards for programming. Please see the
CAUTION notice above when connecting the Miva cards to a -48 volt battery system.
Each card is identified by its position on the back plane. Viewing from the front, the left
card is card 1.
The serial port is fixed with the following parameters:
Bit rate 9600 Bps

Bits 8 bits
Parity None
Stop bit 1
Mode TTY or similar
Flow Control None
Use any terminal program you prefer for configuration as long as the above parameters
are set and the correct cable is used.
3. Which cable to use?
If you wish to connect Miva to a PC or laptop, please use a standard serial extension
cable (the same cable as you would use to extend a mouse). The pins must not be
transposed but connected pin for pin at each end. The Miva back plane has a 9 pin
female connector ready for this cable.

4. Connection test on a single Miva card.
When you have set the terminal and connected the cable, power the Miva unit on, and
type 1h <enter> you should see text appear like this:
Card 1 ->Miva Rev 3.003 S/N 952622 Time 09:10:42 Day 1 date: 25/04/98
Copyright 1998 by Miva Corporation Pty Ltd. Phone 1 800 809 359 for more info.
This interrogates the card and asks for a quick reference help screent o be displayed
like the one above.
Note that the Miva terminal interface is case sensitive
5. Connection test on multiple cards in the frame.
Connect up and then power up the frame with Miva cards inserted. As the cards power
up, each port sends out a boot up string which refers to the location in the frame and
their status. This might look something like this:
^11102A
^21102A
^12102A
^22102A
6. Addressing a single card
To address a particular card in the frame, always type its card number before a
command. Like:
1h <enter>
for the help screen on card 1
or
4h <enter>
for the help screen on card 4

7. Addressing multiple cards
To address all the cards in the frame, type a 0 (zero) before the command. This is used
for settings where you want all cards to receive a broadcast.
For example
This garbled
0CS 12:02:00 2 25/04/98 <enter> message means all
cards are
dsdsgh sfggfdsggg sdfgsg3t4zx6s42 responding. IT IS
NORMAL.
will set all cards to time 12:02:00 day 2 date 25/04/98
WARNING This command prefix will send data to the cards in parallel. All cards
will respond simultaneously and the resulting screen on your PC may appear
jumbled. This is normal.
8. Commands
For the remainder of this section all commands are shown with the card address 1. You
must insert the correct card number or global prefix for them to work.
B. Re-initialising Miva to factory defaults
This completely wipes all the configuration information in Miva and resets it back to the
factory defaults. This could be used to place a board into a known state from which it
can be reprogrammed.
WARNING: Initialisation will reset the card to factory default settings – diversion
numbers, message lengths and locations, active message and mode of operation will
all have to be re-programmed.
1. Command
1II <enter>
Miva will then ask for confirmation-press ‘y’ to confirm (case sensitive).
Miva will print out messages indicating which stage of the process it is at. If there are
no errors, at the end it should say, e.g.:
^110020A (indicates that port one initialized and rebooted)
^110020A (indicates that port two initialized and rebooted)

If there are any errors, please try again and, if they remain, call Miva -- do not use
the card as it will be in an unknown state and may not function as expected.
C. Changes to default settings
1. Number of Messages
Miva comes factory configured with four message blocks enabled. The default message
lengths are:
Message 1: 25 seconds
These can be changed via the serial port if required. The number of messages can be
anywhere between one and nine with the sum of the message lengths being 75
seconds. There are two setting to make when altering the number and length of
message block. You must set the number of messages (1-9) and also the length of
message (0 to 75 seconds expressed as a HEX number) A HEX to Decimal table is
included in appendix F at the rear of this manual.
2. Hookflash duration and pause
When the Miva port is configured as an auto attendant port, a hookflash break will be
generated and a number will be dialled (if programmed) before the Miva port hangs up
the line.
• The default hookflash or timed break length is 125 milliseconds.

• The default pause after hookflash but before dialling (Hook flash pause) is 1000
milliseconds.
• The hang up delay after dialling is 1000 milliseconds

Message Playing Hookflash Dial Transfer Hang Up

D. Application notes for transferring calls
1. When the Miva port is used to transfer a call as in auto attendant mode, it does so
by a hookflash or timed break, followed by the number, followed by hang up. If the
timing of the PABX system is consistent with the default settings of the Miva card,
you should not experience call bounce back as long as the destination number is not
busy and is a valid number.
When calls bounce back to the Miva port there are a number of conditions which
may be causing this:
(a) The destination number is busy and call forward on busy has not been set on the
PABX. If this is the case set call forward on busy to another valid destination.
(b) The hookflash duration (default 125 milliseconds) of the Miva port does not
match the PABX. Set the Miva card via the Engineering port to match that required
for the PABX.
(c) The hookflash pause is too short and the PABX has not sent dial tone to the Miva
port. Miva has dialled the number before the PABX is ready to accept it. Set the
hookflash pause to a longer time and try again.
(d) The hookflash delay is too short and the Miva unit has hung up before the PABX
has started to ring the dialled number. Sometimes the PABX will reject this transfer
and will ring the Miva port again with the original caller on the line. To remedy this,
set the hookflash hang up delay longer and try again. This symptom is especially
noticeable when the transfer is via PABX nodes connected by digital links with
DPNSS. The delays via this signalling method slow down the receipt of ring tone
from the distant node.
(e) The diversion number is not correct!

E. Configuring Miva and Hex to Decimal conversion
All configuration settings are stored in Miva’s EEPROM memory in Hex number
format. Each piece of configuration data is stored in 4 bit ‘nibbles’ which is
represented in the Hex format 0 - 9 and a to f. See the simple table below.
DEC HEX
0 0 EXAMPLE
1 1
2 2 1m f26 xy <enter> is the command to set the
3 3 hookflash timed break and hookflash pause
4 4
5 5 where x = hookflash length in 25ms units
6 6 y = hookflash pause in 200 ms units
7 7
8 8 If hookflash is to be 250 ms then x = a (10 units)
9 9 If hookflash pause is 800ms then y = 4 (4 units)
10 A

12 C
13 D 1m f26 a4 <enter>
14 E
15 F
A full Decimal to Hex conversion table is found on page 44.

Two nibbles form a byte (8 bits). Each byte has an address. These addresses start
at 0E00 and end at 0FFF. For instance
Card address and memory

update command
1m f26 a4
Data is two hex digits 0 to f
Address for data
It is very important to only modify addresses shown in the next table for configuration
changes. If you accidentally change the wrong address, you can return the unit to a
factory default state by typing
1II <enter>
and follow the prompts. Re-enter your changes carefully to avoid mistakes.
Note: Any address less than 0E00 or greater than 0FFF is protected and can not be
modified and therefore if one of these addresses is changed a re-initialisation
will not be required.
The Miva unit will actually respond to a modification outside of these ranges, and
return with address modified; however these areas have been protected and will
not have been updated.

F. Programming via the Engineering Port
The following table lists the command codes, addresses and instructions to allow
configuration changes. The basic command list is:
1m hhh yy <enter> Modify card 1 memory xxx with hex data yy

1d hhh <enter> Dump data from address location xxx
1h <enter> Help command polls for card details
1II <enter> Resets card to factory defaults

G. Decimal to Hex Conversion Notes
The Table shown in Section H below is handy to allow you to convert configuration
data (such as Hookflash times in milliseconds) to Hex, so that it can be entered by the
memory command ‘m’ into the appropriate address in EEPROM memory.
By way of example:
The hookflash time is to be set to 250 ms and the hookflash delay is to be set to 600.
1. Hookflash is set in 25ms units, therefore 10 units are required. ‘10’ converted to Hex
becomes ‘A’. See the table below.
2. Hookflash duration is set in 200ms units, therefore 3 units are required. ‘3’ converted
to Hex becomes ‘3’. Note in some cases the leading 0 is not added.
Therefore the command to enter this data will be (for card 1)
1m f26 a3 <enter>

I. Real Time Clock Operations
The Real Time Clock is used by Miva to switch messages at user specified times (see
section 4 below).
1. To set the clock

Command
CS HH:MM:SS W DD/MM/YY
where: Range
HH is the hour (in 24 hour time) (00-23)
MM is the minutes (00-59)
SS is the seconds (00-59)
W is the day of the week (1-7) (1 = Monday)
DD is the day of the month (00-31)
MM is the month (00-12)
YY is the year (00-99)
There is no error checking done on entry.
Example
1CS 12:55:00 3 03/04/98 <enter> Sets the clock on card 1 to
12:55 PM day 3 on 3rd April 1998.
Response
The command will echo back the time, day and date that it has set the clock to, e.g.:
Card 1->CS Time 12:55 Day 3 Date 03/04/98
If any of the input is invalid or not properly formatted the clock will be set to an invalid
time/date which will produce undefined results.

2. To check the clock
Command
CV
Example
1CV <enter> Checks clock setting on card 1
Response
Miva responds with the time, day of the week and the date, e.g.:
Card 1->CV Time 12:55 Day 3 Date 03/04/98
J. Real Time Clock message switching
How the Message Switching works
Miva’s message switching is a powerful feature which allows the active message to be
changed up to four times a day for each line. The switching can be independently
enabled or disabled for either line and is independent of the mode that Miva is
operating in. This means that you can have Miva change the RVA messages,
Automated Attendant messages or the Music on hold messages.
Each line can be switched up to four times in a day. This allows for a morning
message, afternoon message, night shift message and a “closed” message to be
switched in at various times.
Messages can be switched on intervals of 5 minutes (e.g. 8:00, 8:05, 8:10, etc.). Miva
will only switch when its clock matches the switching time and so, if a user changes the
active message, it will stay that way until the active message is changed again. This
allows the user to override temporarily the active message. The message switching can
also be disabled from within the User menu. If the normal switching pattern has to be
temporarily changed (e.g. for a public holiday), the easiest way is to turn off the
message switching and set the active message manually until things return to normal.

1. To Clear switching times
This will clear all the switching data for that line and day(s).
Command
RC L D<D><D><D><D><D><D>
where Range
L is the line (1 or 2)
D is the day of the week (1-7)
<D> other days to clear (optional) (1-7)
Miva will respond with, e.g.: Card 1->RC Line 1 Day 2 Cleared
Example
1RC 1 1234567 <enter> Clears clock setting on line 1 for all
days.
2. To Examine Switching Times
This will show you the switching times that are currently programmed into the Miva
card.
Command
RE L D<D><D><D><D><D><D>
where Range
D is the day of the week (1-7)
<D> other days to examine (1-7)
Example
1RE 2 123 <enter> Examines line 1 switching times for
days 1,2 and 3
Response
Miva will list the switching data for the days listed in the order that they are listed, e.g.:
Card 1->RE Line 1 Time 08:00 Message 1 Day 3
meaning switching Line 1 to Message 1 on Day 3 at 08:00 or
Card 1->RE Line 1 Spare Day 3
meaning that this is a spare location for Line 1 on Day 3.

3. To Set message switching times
This command is used to set the message switching times. For details on how this
function works, please see the section above under the heading “How the Message
Switching Works”.
Command
RS L HH:MM G D<D><D><D><D><D><D>
where: Range
HH is the hour to switch at (in 24 hour time) (00-23)
MM is the minutes to switch at (00-59)
G is the message to switch to (1-Max Message)
D is the day of the week. (1-7)
<D> other days to set (optional) (1-7)
Example
1RS 2 08:00 1 12345 <enter> Sets message 1 on line 1 to
be the active message for
days 1,2,3,4 and 5
Response:
Miva will echo back the line, times, days and messages that have been set, e.g.:
Card 1->RS: Line 1 Time 08:00 Message 1 Day 4
If the switching data for a line and day is full, Miva will respond with
Card 1->RS: Line 1 Day 2 Full
This may occur for one of two reasons: either the storage space is full of old data or
you are trying to set more than 4 switching times per line per day. If the storage is full
of old data (you can check this with the Examine command), you will need to clear it
using the Clear command and then reprogram that day and line.

VIII. Appendices
