IONOS NMS (which also manages SAGEM ADR2500 eXtra and SAGEM ADR10000c and other products from SAGEM networks range). SAGEM solution is particularly compact. it is made of ADR155c.ADR155C is an STM-1/4 Add-drop Multiplexer that can also be used as an STM-1/4 Terminal. its high capacity. which makes it one of the most comprehensively integrated equipment currently available. It has the following special features: the capacity to integrate not only the usual TDM signals. It has an embedded HTTP server. STM1/4 regenerator or a local cross connect. SAGEM ADR10000c and SAGEM IONOS NMS. its flexibility of configuration. SAGEM . The data access (tributary) are X21/V11 and Ethernet10/100. Equipment have been made to perform complex ring or meshed networks mixing voice and data and benefiting from high quality fibber optic performance and compatibility with public networks. DS3. STM1.SDH Optical multiplexers 2 SDH OPTICAL MULTIPLEXERS 3 SAGEM continues to develop its range of compact SDH multiplexers designed for mixed Voice and Data access networks. The advantages of this solution are the use of optical fiber giving high quality performance for transport voice and LAN connection. E3. A common feature of all this equipment is the compatibility with the SDH networks (open to public operator networks). SAGEM-ADR2500 eXtra is an add-drop multiplexer that allows to make rings or point to point STM-16 networks with E1. These three products are designed for complete operational compatibility. The PDH tributaries are E1. The SDH tributaries are STM1 optical or electrical.ADR155C is an ‘add-drop’ STM1/STM4 multiplexer that can be used for creating ring networks at 63xE1 or 3xE3/DS3 with Ethernet 10/100 and V.

Commissioning is time saving. First. the SAGEM ADR155C is very compact: dimensions are 422 x 91 x 225 (ETSI/19 inch compatibility). The second point is it very easy to install and commission: the shelf is available with 19 inch and ETSI mounting kit. It can be configured as an add-drop.5 SNMP MANAGEMENT SYSTEM The ADR155C is conform to SDH standard transmission norm. E3/DS3 and LAN Ethernet 10/100). new firmware can be downloaded to equipment from IONOSNMS without going to every site.4 MODULARITY This very important advantage is the result of a three dimensional concept. SIMPLE.1. The SAGEM IONOS-NMS is an SNMP management platform that includes a provisioning feature. it features multi-users and differentiated services with access security. The heart of system is made on 5 x 5 VC4 non blocking switch with VC4/VC3/VC12 granularity. And last.1 ADVANTAGES TRUE VOICE/DATA INTEGRATION 4. DTC SAGEM ADR155c ASP/SYS/2007-3098 6/31 .

The SAGEM ADR155C features 4 undedicated slots for aggregate or tributary.1. it is very simple to install and to commission (default configuration flexibility and self-adaptative behaviour) 4. 4. This enables monitoring of alarms or events and configuration of any equipment in the network with a web browser. 4. 4. Maintenance is reduced due to the high reliability of the equipment.1. This application is a friendly user friendly interface.1.2 PROTECTED EQUIPMENT The SAGEM ADR155C implements an HTTP server. LOW POWER EQUIPMENT Designed for the access network.1. The third point is the management and maintenance: the management is very simple with the centralised IONOS-NMS system. This software is adaptable to the size of the network. No special training is required for operators. a regenerator or a cross connect. Moreover.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). ADR takes advantages of SAGEM experience in designing third generation costeffective and highly integrated equipment. Its high level of integration means it is also reliable and low consumption equipment. such as industrial areas. These loops can be implanted in any areas served by fibre optic cable.ADR155C are used in access networks to create local loops connected to the public network.

At least one of the SAGEM .2 CENTRALIZED MANAGEMENT (IONOS-NMS) DCC channel communications are protected in the same way as the STM-1/4 line.ADR155C or ADR2500 eXtra in the network is linked to the SNMP manager. There are two possible centralized management levels: network view: showing all network links. The management network is composed of an Ethernet LAN which includes a workstation supporting IONOS-NMS (PC or SUN Server). equipment view: showing modules in a particular equipment unit..

It needs one ADR155C as a “gateway” which routes the management packets.1 The ADR has the possibility to transport management of ADR155C over VC12. This allows another supplier management traffic to be transparently handed over through an ADR155C sub-network. the ADR155C can be connected to all SDH vendors.
