Element Manager.

4.2.5.2.3 Nortel Media Gateway 1000

Distributed throughout the IP network, Nortel Media Gateway 1000 acts as a bridge between IP

and traditional telephony networks (such as the PSTN) by housing various cards that perform

line, trunk, and translation functions. The hardware for the entire Media Gateway 1000 portfolio

has the same characteristics: four slots that can be used for media cards, analog and digital line

cards, analog and digital trunk cards as well as various applications.

4.2.5.2.3.1 Nortel Media Gateway 1000S

The Media Gateway 1000S is used with the Communication Server 1000S to support PSTN

trunks, analog/digital telephone resources, TDM application cards and Voice Gateway Media

Cards. Each Media Gateway can support one Media Gateway Expander. The Media Gateway

1000S contains a gateway controller card (called SSC card) and four slots for flexible

configurations of line, trunk, and application cards. The SSC card controls the interface and

application cards and acts as a call processor in the survivable mode. The Call Server database

is automatically synchronized onto this controller. Application cards provide interfaces to

applications like CallPilot and Nortel Integrated Applications portfolio.

4.2.5.2.3.2 Nortel Media Gateway 1000E

The Media Gateway 1000E is used with the Communication Server 1000E to provide basic

telephony media services – including tone detection and generation and conference – to phones.

It operates under direct control of the Call Server and can support an optional Media Gateway

1000E Expander. The Media Gateway 1000E contains a gateway controller card (called SSC

card) and four slots for IPE cards and Voice Gateway Media Cards. The Media Gateway 1000E

supports CallPilot and Nortel Integrated applications. It also provides direct physical connections

for digital and analog (500/2500-type) telephones as well as analog trunks for telephone and fax.

4.2.5.2.3.3 Nortel Media Gateway 1000T

The Media Gateway 1000T provides the Communication Servers 1000E/S with digital trunk and

PRI access to the PSTN and to other PBX systems. The Media Gateway 1000T contains a

gateway controller card (called SSC card) and four slots for IPE cards. It also supports an

optional MG 1000T Expander. Unlike the MG 1000Es, the MG 1000T platform does not operate

under the direct control of the CS 1000E Core Call Servers. Instead, the MG 1000T provides the

primary processing for the MG 1000T platform. The MG 1000T Core SSC card controls the circuit
