APPLICATIONS


3. APPLICATIONS

3.1. ADVANTAGES

3.1.1. TRUE VOICE/DATA INTEGRATIONAND PROTECTION

SAGEM ADR2500 eXtra is compliant to SDHstandards and it is a versatile add-dropmultiplexer with a diversity of access (including 2Mbps, 34 Mbps, 45 Mbps, Ethernet, FastEthernet, 155 and 622 Mbps, evaluative to 2,48Gbps) with high quality of service (trafficprotection). From the LAN/WAN bridgetechnology, it can transport STM-4c and STM-16c with concatenation and Gig Ethernet.

3.1.2. HIGHLY PROTECTED EQUIPMENTSDH design of ADR2500 eXtra gives the benefitof standard traffic protections (SNCP, MSP, andMS-SPRing).Cards whose failure could affect the traffic canbe protected in 1+1 mode and tributaries can beprotected in 1:4.

3.1.3. COMPACT, SIMPLE, RELIABLE,LOW POWER EQUIPMENT

Designed for the Metro Network, the SAGEMADR2500 eXtra is very compact: dimensions are450 x 280 x 645 mm.Its high level of integration means it is also areliable and low consumption equipment.And last, but not least, it is very simple to installand to commission (default configurationflexibility and self-adaptive behaviour).

3.1.4. SCALABILITYThe SAGEM ADR2500 eXtra is a versatileplatform. It can be configured as an add-drop, aterminal multiplexer, a regenerator or a cross-connect.The SAGEM ADR2500 eXtra features 8 notdedicated slots for tributaries. It can give accessat the same time to 252 E1 (protected in 1+4)plus 12 STM-1 or 252 E1 unprotected plus 16STM-1.

The heart of the system is made on a 64x64VC4/VC4-4c/VC3/VC12 non-blocking Switch.

3.1.5. SNMP MANAGEMENT SYSTEMThe SAGEM ADR2500 eXtra implements anHTTP server. This enables monitoring of alarmsor events and configuration of any equipment inthe network. This application is a friendlygraphical windows-type man-machine interface.The SAGEM IONOS-NMS is an SNMPmanagement platform that includes aprovisioning feature. This software, adaptable tothe size of the managed network, runs on aWindows XP or a UNIX workstation; it featuresmulti -users and differentiated services withaccess security.

3.1.6. A SDH COST-EFFECTIVESOLUTION

Money saving is a leading goal of the SAGEMSDH family. Generally speaking, SDH/SONEThas proven to be one of the most cost-effectivetechnologies at the present time and the mostwidespread world-wide.This very important advantage is the result of athree dimensional concept.First, ADR2500 eXtra takes advantage ofSAGEM experience in designing next generationcost-effective and highly integrated equipment.The second point is, it is easy to install andcommission: the shelf is available with 19 andETSI mounting kit. Commissioning is timesaving.The third point is the management andmaintenance: the management is very simplewith the centralised IONOS-NMS system andMaintenance is reduced due to the highreliability of the equipment. Moreover, newfirmware can be downloaded to equipment fromIONOS-NMS without going to every site.

APPLICATIONS


FIBER OPTIC ACCESS NETWORK

The SAGEM - ADR2500 eXtra addressesaccess networks to create local loops connectedto the public network, with SDH, PDH interfacesfor voice, Gig, Fast and Ethernet interfaces fordata. These loops can be deployed in any areasserved by fibre optic.

3.2. INFRASTRUCTURE NETWORK

SAGEM ADR2500 eXtra is perfectly suited forinfrastructure networks in order to connect lowerlevel public switches to higher level publicswitches.

ADR2500 eXtra provides up to 252 E1 protectedplus 12 STM-1 in a single shelf. In case morePDH accesses are required, other ADR shelveswithout STM-16 interfaces can be connected(and then give access to the whole 1008 E1).

The granularity at VC4, VC3, VC12 levels willallow to optimise the traffic configuration.

3.3. PRIVATE NETWORK

The SAGEM - ADR2500 eXtra is ideal forbuilding high capacity private networks that

cover wide areas: e.g., industrial sites withmultiple buildings extended campuses.

The SAGEM - ADR2500 eXtra offers thebenefits of fibre optics and SDH technology(security, management).

For these applications, voice (inter-PABX links)and data (LAN interconnection, POS, ATM VC4-4c) compatibility is very important; open accessto the public network is also of major benefit forlinking remote sites.

3.4. PUBLIC UTILITY COMPANYNETWORKS

The SAGEM range of equipment (SAGEM -ADR155C, SAGEM FMX and SAGEM ADR2500eXtra) can be used for the construction of largelinear networks such as electrical, pipeline,railway, motorway or tunnel networks.Intermediate stations provide add-and-drop forup to 63 x 2 Mbps signals. Protection istherefore achieved with flat rings.

APPLICATIONS


3.5. ALTERNATIVE TO STM-64

Compactness of ADR2500 eXtra makespossible to install four shelves in two 42U racksplus the MUX 10000, which is a 1U high 4channels multiplexer / demultiplexer. Thissolution therefore is able to transmit the traffic at10 Gbps and makes an alternative to STM-64.This is also a scalable solution as it is possibleto start with one ADR2500 eXtra connected toMUX10000 and then to add the other oneswithout affecting the traffic (pay as you growsolution).

3.6. ETHERNET OVER SDH (EOS)

3.6.1. NEXT GENERATION SDHThe goal of Next Generation SDH is to transportdifferent type of services, both circuit mode andpacket mode at the same time. By incorporatingdifferent technologies the aim is to keep thestrong points and eliminate the weakness.The main points are :

- Multiservice transport based on SDH.SDH has efficient protection services as wellas mature technology.

- The flexibility of the trail creation iscarried by virtual concatenation and LCASprotocol. The virtual concatenation allowsstacking of bandwidth of different VC12,VC3or VC4 containers, in order to get the virtualcontainer to an adjustable bandwidthaccording to the needs. The granularityrespects 2 Mb/s, 50 Mb/s or 150 Mb/s. LCASprotocol insures the extremitysynchronisation when there is an adjustablebandwidth, avoids the momentaryinterruption services.

- Choosing the best encapsulation modefor each services :

- The in circuit flow mode, as a flow of E1PDH end E3/DS3 that are encapsulated in avirtual container (VC12/VC3) in following themultiplexing scheme proving SDH efficientquality.

- In flow packet mode using the new GFP-Fencapsulation mode which combine very lightoverhead, with the maintenance of the octetalignment and the packet size.

- The important innovation of thetranslater for Ethernet in the first mile

for transporting the flow of Ethernet packets :policing, shaping, double tagging, EthernetPrivat Line, Ethernet Virtual Private Lan.
