42 Overview
Figure 7
Single server port network connections (dual-homing - distributed)
The following figure illustrates 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 ensure there isn’t a single point of
failure. Nortel recommends this configuration in a dual CPU Call Server
configuration. In this configuration, the CP-PM 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 switches fails, avoiding a CPU switchover
due to a network outage.
