1.3 Applications
AN-TDM-IP-1E1-A could be worked with E1 over Ethernet interface
www.ad-net.com.tw -1-
multiplexer AN-TDM-IP-STM-1, make point-to-multipoint application ,and point to

point of connection, Typical application is shown in Fig 1.3-1~Fig 1.3-3.
Figure 1.3-1 Convergent Application
Figure1.3-2 Typical application of wireless network
Fig. 1.3-3 The typical application of cable network

AN-TDM-IP-1E1/2E1-A could cooperate with wireless bridge of most
manufactories in wireless network application use, At present, some the sold wireless
bridge transmission bandwidth change with the Ethernet packets, some Bridges will
introduce the packet delay jitter, when work with the different wireless bridge, need
to adjust E1/T1 signal seaied length and jitter, in order to get the best transmission
effect.
Note : This equipment is used together with the wireless Bridges, usually
through reticule and outdoor antenna system of wireless bridge connected,
there is lightning risk at this time, must be in an upward in combination of
Ethernet lightning protection protector, otherwise lightning will make seriously
damage to the equipment, danger to the staff .
1.4 Timing modes

To emulate a transparent E1 channel over a packet network, the
AN-TDM-IP-1E1/2E1-A not only conveys data stream content correctly from the
source to the destination, but also recovers the E1/T1 timing from the source at the
-2- www.ad-net.com.tw
destination accurately. Packet networks do not provide such built-in timing

transparency mechanism as TDM networks do. AN-TDM-IP-1E1/2E1-A uses its
proprietary algorithm to reconstruct the E1 clock at the destination. The recovered
clock is of very high quality, with low jitter and wander. Typical frequency offset is
within ±5ppm, and jitter is below 0.1UI. It can be adopted in most applications. This
timing mode of rebuilding the E1 clock at the destination is called Adaptive Timing.
For applications where separate clock distribution network exists, another
timing mode, Loop back Timing, may be used for maximum clock quality. In this
mode, AN-TDM-IP-1E1/2E1-A rebuilds the E1/T1 output code stream using the
clock extracted from E1/T1 input signals. AN-TDM-IP-1E1/2E1-A built-in memory
can eliminate the wander completely. It will switch to Adaptive Timing automatically
once the input signals are lost.
The two timing modes of AN-TDM-IP-1E1/2E1-A are showed in Fig.1.4-1.
Fig.1.4-1 E1Timing modes

Correct timing mode setting is important for smooth operations. In most cases,
setting both units to adaptive timing mode is sufficient. But sometimes, setting one
unit to loop timing mode may work better. For example, setting the
AN-TDM-IP-1E1/2E1-A unit connected with the clock master (such as local
exchange) to loop back mode, and the other unit connected with the clock slave
(such as PBX remote module or PCM terminal) to adaptive mode, is probably
better than setting both to adaptive modes. It’s better to set the both sides
AN-TDM-IP-1E1/2E1-A to loop back timing mode when the both sides equipments
use synchronous master clock. In another case, set the both sides
AN-TDM-IP-1E1/2E1-A to adaptive timing mode when the both sides equipments
use asynchronous master clock.
One typical error in telecom applications is to connect two communication
devices that are both clock slaves. Neither will AN-TDM-IP-1E1/2E1-A support
such operation no matter how the timing modes are set.
Note: The Lock Clock usually takes several minutes to stabilize. During
that period, clock drift may exceed the limit, errors and slips may occur.
Various timing schemes are listed in Table 1.4-1, for applications depicted in
Fig.1.4-2.

2. System Architecture
2.1 Function Description
The core of AN-TDM-IP-1E1/2E1-A is the TDM/Packet processing unit. It
truncates E1/T1 data stream, and encapsulates the data into Ethernet packet with or
without IP headers. The packets are passed to the Ethernet switch unit via MII
interface, and are sent out through the uplink ports.
In the reverse direction, packets from the uplink ports are sent to the
TDM/Packet processing unit for reassembling the original E1/T1 data stream, and
outputting via E1/T1 interface. TDM/Packet processing unit need to process the
reassembled data to recover the E1 clock which is the key element of the device.
Very sophisticated algorithm is used to ensure that the reconstructed clock will meet
the stringent requirement of TDM applications. The most important parameters are
bit rate, jitter, wander, and signal delay.
The user can modify various operational parameters through Network
Management.

3.2 Ethernet/optic fiber connections

AN-TDM-IP-1E1/2E1-A provides four 100Base-Tx Ethernet electrical
interfaces (two ports are uplink ports used to connect with transmission network and
the other two are local data ports used to connect with local Ethernet), and one
100Base-Fx optical interface used as either uplink port or local Ethernet port such as
switch.
Ethernet Optical adopts SFP integrated optical modules, and the port labeled（
is for optical signal output, （ for input. Also Ethernet optical port can use
single-fiber optical module which has only one optical interface. The wavelength of
single-fiber optical module means its luminescence wavelength, 1310nm or 1550nm.
It should note that equipments with the same luminescence wavelength cannot
connect with each other. So it should select the equipments with the match
luminescence wavelength when using the single-fiber module.
Note:
1. At auto-negotiation mode, Ethernet electrical port supports HP auto-MDIX
function and it can check the transmission and receiving sequence and make
configuration. So both MDI and MDI-X interfaces are supported and both
cross line and direct line can be selected.
2. Network Management can be used for all the Ethernet ports except Data1
port. But to ensure VLAN setting not affecting monitoring, it’s better to use
the Ethernet electrical port labeled “Data2/NM” as the network
management monitoring interface.
4. Troubleshooting
After power up of equipment AN-TDM-IP-1E1/2E1-A the system
should start after 90seconds to work properly. The system completion startup SYS
light change from long bright to flashing light. You can observe each interface light to
judge each port working statue.
4.1 Common fault diagnosis and ruled out

This paragraph describes common faults that may occur during installation and
maintenance. Please seek support from us for other problems.
4.1.1 PWR FAIL LED ON

The PWR FAIL light indicates that the corresponding power supply board is not
complete plugged in or not connected with, please check the following

subject: the power supply to meet the requirements or not, the power plug is
connected, the switch is open.
4.1.2 SYS LED does not blink

After star up 90 seconds or during working statue, the SYS light flashing that
is mean system have not start up completion or program problem, you can turn off
the power and reboot, if still does not start up properly you need to find supplier for
technical support.
4.1.3 Ethernet Electrical port LINK LED OFF

Ethernet electrical port LINK light off indicates that corresponding Ethernet
port does not connect properly. You can check the cable connection, cable line
ordering, under mandatory mode does it using the straight-through cable (crossover
cable), the electrical interface connection does match the client configuration whether,
and connection with network device is working properly or not.
4.1.4 Ethernet optical port L/A LED OFF or OLOS LED ON

Ethernet optical ports L/A light off indicate that the corresponding Ethernet
does not establish connect properly. The OLOS light on indicates
no received light. Can check the corresponding fiber is connected or not, the using
single-fiber module and the equipment connected to the same emission wavelength
(should using wavelength as pair optical modules), and device working properly or
not.
4.1.5 E1/T1 Alarm LED ON

There are two groups of LEDs, PKT LOS and LOS for E1 alarms LEDs.
When E1 LOS LED is on, loss of E1 signal fault is detected by AN-TDM-IP.
Possible causes include:
The downstream equipment such as telephone exchange or PCM terminal
is powered off.
The E1 cable connection looses or broken.
E1 LOS LED blinks when respective input E1 signal is AIS, i.e. the content of
E1 data is all 1. Such alarm indicates fault conditions on the part of the downstream
equipment.
E1 LOS site is controlled by Dip Switch RA state. When RA Dip Switch ON, the
red LEDs indicate remote E1 LOS state. When RA Dip Switch OFF, the red LEDs
indicate local E1 LOS state.
4.1.6 TWO ENDS DEVICES CANNOT CONNECT

Both sides of devices in the same Ethernet broadcast domain, checking both side
of device IP address should on dual relationship. Check MAC address is unique
(include other device on the same network); Using Ping command to check network,
checking bandwidth is sufficient or not.
If two sides of devices are not in same Ethernet segment, checking device IP
default gateway setting, IP address, IP address mask, and check conflicts of MAC
address or IP address; check bandwidth is sufficient. IP address and gateway
address can be set by NMS, MAC address set by manufacture.
Check both ends of the device VLAN setting should be in accordance with each
other.
4.1.7 Both Sides devices of E1/T1 have slip

Check both sides devices AN-TDM-IP-1E1 E1/T1 clock setting, at least one of
device should be Master-Clock.
Check AN-TDM-IP-1E1/2E1-A time mode setting. If both sides of the E1/T1
equipment are not in the state of the synchronization, units timing model must be
adaptive timing, not loop timing.

5.4.2 Ethernet Senior Management

Ethernet senior management supports MAC address aging time, Ethernet port
QoS management and throughput limiting. MAC address aging time range is
0~99999 s (default: 300s).
Fig 5.4-2 Ethernet management

For Ethernet interface 1~5, we can enable QoS (based on port, 802.1p and TOS)
Fig 5.4-3 Ethernet QoS configuration
Port throughput limiting of Ethernet senor management includes enable Ethernet

port throughput limiting and speed configuration (supporting entry speed limiting).
As shown in Fig 5.4-4. Speed class of Ethernet interface is shown in Table 5.4-2.
When we configure the maximum port speed, if the value is not equal to any speed
class, it will select the lower speed class proximal to this value. For example, value is
set to 70, after clicking Submit, the value will change to 64, means the maximum
speed is 64KB.

5.4.3 VLAN Management

Two uplink Ethernet electrical interfaces support 1+1 protection. After enabling
1+1 protect, equipment configure Q in Q VLAN automatically and user only need to
configure VID of uplink Ethernet electrical interface and monitoring port. As shown
in Fig 5.4-5 and Fig 5.4.6.
Fig 5.4-5 uplink 1+1 protect configuration
Fig 5.4-6 configure Q in Q VLAN automatically

AN-TDM-IP-1E1/2E1-A Ethernet supports 802.1 Q VLAN and Q in Q
VLAN. 802.1Q VLAN is that adding the VLAN tag in front of Ethernet frame type.
Q in Q VLAN is that nesting the VLAN (S-Tag) of operators in 802.1Q outer layer
to enable the VLAN stacking. VLAN management parameters are shown in Table 5.4-3.
