Main Office and Branch Office migration

All Main Office Call Servers in CS 1000 are Large System software-stream-based. The Main Office
TN (MOTN) in a Branch Office is always set to the Large System software stream MOTN.
In a Branch Office where you migrated the Main Office from an SSC to a Server, the LD 20 PRT on
the branch may incorrectly display the MOTN using the Small System TN format until you reenter
the MOTN using the Large System TN format. You must manually correct the MOTN. Therefore,
you must manually change the Branch User ID, 63.20, to 96-0-3-20.

Media Gateway 1000B

The Media Gateway with Gateway Controller has a number of differences in hardware capability
compared with older Branch Offices. You can use an MGC card or a CP MG card as the Gateway
Controller.
The has six external Ethernet interfaces, and the CP MG has external four Ethernet interfaces. The
Ethernet ports are for connecting to The ELAN and TLAN subnets of the CS 1000E system. The
Ethernet interfaces on the Gateway Controller are configured to Autonegotiate mode by default. You
can change the settings for ports to 100 Mbps full duplex by using the setup command.
With a properly designed data network, you can use the multiple ELAN and TLAN interfaces to
implement a dual-home configuration for the MG 1000B
