Main Office and Branch Office Migration
All Main Office call servers in CS 1000 Release 5.0 are large system based.
A CS 1000 Small System Main Office is no longer supported. Since all CS
1000 Release 5.0 Small System Controller (SSC) based Main Offices have
been migrated to Call Processor Pentium Mobile (CP-PM) Call Servers, the
Main Office TN (MOTN) Type in a Branch Office will always be set to the
large system MOTN Type.
In a system where the Main Office has been migrated from a SSC to CP-PM
call server, the LD 20 PRT on the branch will not correctly display the MOTN
using the small system TN format until the branch has been migrated or
upgraded. In the case where the branch is SSC based, the LD20 PRT will
remain incorrect until the Branch Office Call Server has been migrated to a
CP-PM call server. In the case where the branch is already a large system
(CP-PII or CP-PIV), then the LD 20 PRT on the branch will remain incorrect
until the branch has been upgraded to CS 1000 Release 5.0.
MG 1000B (MGC) compared to the MG 1000B (SSC)
The MG 1000B with MGC has a number of differences in hardware
capability when compared with Release 4.5 gateways.
The MGC has six Ethernet interfaces for connecting to external networking
equipment. Three are reserved for ELAN connections and three are
reserved for TLAN1 connections. The six external Ethernet interfaces on
the MGC are set to Auto Negotiate mode by default. You can change the
settings for ports 1E, 2T, E and T to 100 Mbps full duplex by using the
