ADVANTAGES
TRUE VOICE/DATA INTEGRATION
4.1.5
The ADR155C is conform to SDH standard transmission norm. It is a versatile add-drop multiplexer with a diversity of access (including E1, E3/DS3 and LAN Ethernet 10/100). 4.1.2 PROTECTED EQUIPMENT
The SAGEM ADR155C implements an HTTP server. This enables monitoring of alarms or events and configuration of any equipment in the network with a web browser. This application is a friendly user friendly interface. The SAGEM IONOS-NMS is an SNMP management platform that includes a provisioning feature. This software is adaptable to the size of the network, runs on a Windows XP or UNIX workstation; it features multi-users and differentiated services with access security. 4.1.6 A SDH COST-EFFECTIVE SOLUTION
SDH design of ADR155C gives the benefit of standard traffic protection (SNCP and MSP protections with switching in less than 50 ms). 4.1.3 COMPACT, SIMPLE, RELIABLE, LOW POWER EQUIPMENT
Designed for the access network, the SAGEM ADR155C is very compact: dimensions are 422 x 91 x 225 (ETSI/19 inch compatibility). Its high level of integration means it is also reliable and low consumption equipment. And last, but not least, it is very simple to install and to commission (default configuration flexibility and self-adaptative behaviour) 4.1.4 MODULARITY
This very important advantage is the result of a three dimensional concept. First, ADR takes advantages of SAGEM experience in designing third generation costeffective and highly integrated equipment. The second point is it very easy to install and commission: the shelf is available with 19 inch and ETSI mounting kit. Commissioning is time saving. The third point is the management and maintenance: the management is very simple with the centralised IONOS-NMS system. Maintenance is reduced due to the high reliability of the equipment. No special training is required for operators. Moreover, new firmware can be downloaded to equipment from IONOSNMS without going to every site.
The SAGEM ADR155C is a versatile platform. It can be configured as an add-drop, a terminal multiplexer, a regenerator or a cross connect. The SAGEM ADR155C features 4 undedicated slots for aggregate or tributary. The heart of system is made on 5 x 5 VC4 non blocking switch with VC4/VC3/VC12 granularity.

PRIVATE NETWORK
The SAGEM - ADR155C are used in access networks to create local loops connected to the public network, with direct PDH interfaces and Ethernet for local networks. These loops can be implanted in any areas served by fibre optic cable, such as industrial areas, suburban areas and residential areas.
Business districts typically feature a very high demand for both tributary capacity and a wide variety of services (telephony, leased lines, ISDN terminals, fax, etc.).When used in conjunction with low rate multiplexers (SAGEM DLC product range : FMX, etc.), the SAGEM ADR155C meets this demand by offering a single collection point for all types of signals (voice, data, video) for connection to a Central Office switch that may be located many tens of kilometers away (up to 100 km in a single optical hop).

EPLAN EXTENSION
The SAGEM - ADR155C is ideal for constructing private networks that cover wide areas: e.g., industrial sites with multiple buildings, extended campuses. The SAGEM - ADR155C offers the benefits of fiber optics and SDH technology (security, management). For these applications, voice (inter-PABX links) and data (LAN interconnection) compatibility is very important; open access to the public network is also of major benefit for linking remote sites.
Linked to a router or a switch, the SAGEM ADR155C makes it possible to construct very simply a MAN/WAN to cover several remote sites to constitute a multi-LAN structure without the need for leased line rental between routers/switches.

BASIC MODULE
module features the following
5.3.4.1
STM-1 line protection is obtained by doubling the fiber optic cable and the STM1 interface module (1+1) : transmission over two channels (main and backup) receiving-end selection from either channel. There is automatic switchover to the protection link in accordance with the criteria described in ITU-T recommendation G.823. There is no interruption to the order-wire and data flows with MSP 1+1 protection. Protection switching is initiated upon : a line fault, STM1 interface module fault, an operator command. When detected on the main channel, the following fault conditions initiates MSP protection : SF (Signal Fail): logic ORing of : STM-1 incoming signal loss (LOS STM1) STM-1 loss of frame alignment (LOF STM-1) STM-1 multiplex section AIS detection (MS-AIS) Byte B2 excessive bit error rate (EBERB2) STM1 (ADRIC) interface module absence. SD (Signal Degrade): B2 bit error rate greater than configurable threshold. The SF and SD indications are processed and filtered (fault persistency filter with configurable time persistency). This activates the K1/K2 protocol described in ITU-T recommendation G.783 to initiate the protection mechanism.
Power supply: 48V power converter Equipment operation (SEMF and MCF functions) Cross-connect core 21 x E1 interface Synchronisation 5.3.1 POWER SUPPLY
The power supply features two -48 V inputs (normal and backup) protected by diodes and filtered against electromagnetic surges. A 110/220v can also be used. 5.3.2 FAN (OPTION)
The Fan module is mandatory only with the GFP150 card, and can be changed without dismantling the sub-rack. 5.3.3 OPERATION
The operation module is used for supervising and configuring all equipment functions. The operation interfaces are the DCC channels of the STM1/4 interfaces, an Ethernet 10baseT interface with the central management system (IONOS-NMS) and an RS232C interface with a VT100 type terminal. 5.3.4 CROSS-CONNECT AND SWITCHING CORE
The core is a 1/3/4 cross-connect (VC-12, VC-3 and VC-4 cross-connect) which has the capacity to process one VC-4 per tributary slot and one VC-4 on the mother board, i.e. a total of 5 VC4s. ADDITIONAL FUNCTIONS 1+1 PROTECTION All the main protection modes are possible with the SAGEM - ADR155C: STM1 optical line protection (MSP 1+1) VC-12 and VC-3 and VC-4 path protection (SNC-P)
12/31
Functional description
5.3.4.2
5.3.6
SYNCHRONISATION
SNC-P path protection is used in ring topologies and consists in using the two sides of the ring: one for the normal path, the other for the backup path. When detected on the main channel, the following fault conditions initiate a switch: SF (Signal Fail): OR logic of: AIS detection at path termination (LPAIS)
The SAGEM - ADR155C : uses its own timing source to synchronise transmission via the STM1 interface module, can provide the synchronisation for other equipment, can be synchronised to an internal or an external source. support holdover mode (option of the chassis) 5.3.6.1 Synchronisation sources
Byte B3 or V5 excessive bit error rate (EBER-B3/V5) SD (Signal Degrade): B3 or V5 bit error rate greater than configurable threshold. The SF and SD indications are processed and filtered (fault persistency filter with configurable time persistency). The switching process is conform to G841 norm after confirmation of the originating fault, and the switch status is maintained until tributary signal restoration. The ADR155C offers the possibility to exchange the working and the protection path (swap SNC). 5.3.5 21 X E1 INTERFACE
The SAGEM - ADR155C may be synchronised to the following alternative timing sources : the East, West, main or standby STM-1/4 aggregate signal, one of the 2 Mbit/s tributaries, ITU-T G.703-compliant 2048 kHz external clock signal, the internal local oscillator. 5.3.6.2 Automatic mode
The interface module provides the following functions : HDB3 conversion, 2 Mbit/s signal multiplexing, formation of TUG-3 tributary unit groups, formation of AU-4 administrative units.
In the event of a failure of the active sync source, synchronisation switches automatically to one of various prioritised standby sync sources. This switching mechanism can be reversible. 5.3.6.3 Manual mode
It is possible to force-switch to one of the available sources. 5.3.6.4 Holdover mode (factory option)

Engineering order-wires and digital service channels interchanged by both ends of a network. 5.4.3.1 Engineering Order-wires and Digital Service Channels
5.4.1
The STM1 card offers one SFP access. The STM1 interface module includes STM1 multiplexing functions, VC-4 processing, insertion of the EOW and auxiliary channels. The STM1 card supports the following module: Module SFP S1.1 DDM Module SFP IC1.1 DDM Module SFP IC1.2 DDM (1310 nm) (1310 nm) (1550 nm)
A digital channel (E1 or E2 overhead byte) in the SDH frame is reserved for transport of a digital engineering order-wire (EOW). Digital service channel protection is as with 1+1 line protection. The E1 or E2 and F1 bytes are available over a SubD/HE5 connector on the module front panel. To have a voice signal EOW, it is necessary to have an external mechanism (SAGEMEOW300) which adapts the 64 kbit/s digital signal of the E1 and F1 interfaces.
DDM means those SFP offers optical monitoring features : transmitted power, received power, laser temperature, laser current and laser voltage. 5.4.2 STM1 DUAL
5.4.4
STM4 INTERFACES
The STM1 DUAL offers two accesses, one access for SFP module and one access for electrical access (1.0/2.3), with only one being active. This is the card used for STM-1 electrical requirement.
The STM4 interface module includes STM4 multiplexing functions, VC-4 processing, insertion of the EOW and auxiliary channels overhead interface. Three optical cards are available: S4.1 Interface L4.1 Interface L4.2 Interface (1310 nm) (1310 nm) (1550 nm)
5.4.3
OVERHEAD BYTE PROCESSOR The use of two STM1 or STM4 optical interfaces makes it possible to constitute a 1+1 terminal multiplexer or a 1+0 "add-drop" multiplexer. STM-4 interfaces use fixed transceivers, no SFP. The SDH functions carried out are as compliant to G.783.
Path overhead (POH) and section overhead (SOH) bytes, which are added to and dropped from the SDH frame, carry various items of supervisory information relative to the STM-1/4 links : frame alignment bytes, parity check data,

STM-4 CROSS-CONNECTION This upgrade is an in-service upgrade in case of a ring topology. The impact on existing traffic is limited to a protection switch-hit for each ADR155C upgraded in the ring.
The ADR has a switching capacity of 5 STM-1, it means that one slot has one VC4 bandwith. In case of STM-4 cards, it means it is possible to have access to 63 E1 / 1 VC4 and so the three other VC4 are by passed.. The shelf can be upgraded from STM-1 to STM-4. In this shelf, the STM-4 boards must be inserted in slot B and D ; other boards can be plugged in any 4 slots.

6.1 OPTICAL LINK BUDGET
In SDH networks, the system penalty does not affect optical output power parameters because the latter include temperature variations (5C/45C) and above all ageing.
The equipment (or system) power budget is expressed as dB available between the S and R interfaces of the system, i.e. the difference between average transmitter output power and the optical input power necessary to obtain a BER value equal to or less than 10-10.
Standard Wavelength (nm) Data rate (Mbit/s) Code Output power (S point) Sensitivity (R point) Max level (R point) Connector
All this data is valid for G.652 mono-mode fibers. The optical cards used are also compatible with multimode optical fibers. In this case the cable length is limited to around 15 km.
