MG 1000B platform hardware description

The MG 1000B system has been enhanced for CS 1000 Release 5.0 Branch

Ofﬁce. The CP-PM Call Server and MGC replace the SSC (Motorola) used

in the Release 4.0/4.5 MG 1000B. The VoiceGateway Media Card is still

supported however,the DSPs are also availableon the MGC.

Twonew DSP Daughterboards are included in the CS 1000 por tfolioof

products. The daughterboards are available in two different sizes, a 32-port

daughterboard and a 96-port daughterboard. These daughterboards are

located on the Media Gateway Controller (MGC) card to provide DSP

resources for connecting IP and TDM devices. These daughterboards

eliminate the need to instal the VoiceGateway Media Cards within the CS

1000E Media Gateways (MG 1000B) chassis, to saveslots and reduce cost

over the current VoiceGateway Media Card solution. The addition of the

DSP Daughterboards into a MG 1000B system does not limit the use of

VoiceGateway Media Cards (either Pentium or Strong-Arm versions), either

for DSP-only functionality or for the full IP Line application within the same

system. The MGC is used only in the Media Gateway chassis or Option

11C-style cabinets. From a functional perspective, the DSP Daughterboards

behavein a similar manner as the current VoiceGateway (VGW) application

on the Voice GatewayMedia Card.

Support exists for four conﬁgurations:

•a system with no DSP DBs or Voice GatewayMedia Card (A pure TDM

system, single media gateway).

•a system with only Voice GatewayMedia Cards

•a system with only DSP DBs

— a 32-port daughterboard in daughterboard position 1

— a 32-port daughterboard in daughterboard position 2

— A 32-port daughterboard in daughterboard position 1 and a 32-port

daughterboard in daughterboard position 2

— a 96-port daughterboard in daughterboard position 1

— a 96-port daughterboard in daughterboard position 1 and a 32-port

daughterboard in daughterboard position 2

•a system with DSP DBs (all of the position combinations described in c)

and Voice GatewayMedia Cards.

The basic hardware of an MG 1000B platform includes the MG 1000B Core

and the Signaling Server.
