Figure 15 "Multiserver port configuration: dual homing (distributed)" (page

67)

shows a typical network configuration for a dual CPU Call Server

configuration that supports dual-homing of both the ELAN and TLAN.

Multiple Layer 2 switches are used to ensure there is no single point of

failure. This is the recommended configuration in a dual CPU Call Server

configuration. In this configuration, the Call Server benefits from the

dual-homing feature of the MGC and remains connected to the network

even if one of the Layer 2 ELAN subnet switches fail, therefore avoiding a

CPU switchover because of a network outage.

Cascading of the MGC network connections is allowed, up to a maximum

of two chassis. The MGCs can be cabled directly without the need for

external Layer 2 switches, which is the type of configuration recommended

for a pure TDM solution.

ELAN and TLAN subnet connections

An MGC installed in the PRI Gateway requires both ELAN subnet and

TLAN subnet connections. These procedures are the same as for the

MG 1000E with the MGC. For a full description of connecting CS 1000E

system components, see Communication Server 1000E Installation and

Commissioning.
