The diagrams throughout this document show a CS 1000E main office. All
of the systems appearing in the list perform identical main office functions
as far as the Branch Office feature is concerned.
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 Voice Gateway Media Card is still
supported however, the DSPs are also available on the MGC.
Two new DSP Daughterboards are included in the CS 1000 portfolio of
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 Voice Gateway Media Cards within the CS
1000E Media Gateways (MG 1000B) chassis, to save slots and reduce cost
over the current Voice Gateway Media Card solution. The addition of the
DSP Daughterboards into a MG 1000B system does not limit the use of
Voice Gateway 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
behave in a similar manner as the current Voice Gateway (VGW) application
on the Voice Gateway Media Card.
Support exists for four configurations:
• a system with no DSP DBs or Voice Gateway Media Card (A pure TDM
system, single media gateway).
• a system with only Voice Gateway Media 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 Gateway Media Cards.
The basic hardware of an MG 1000B platform includes the MG 1000B Core
and the Signaling Server.
