The following figure illustrates a typical network configuration that supports
dual homing of both the ELAN and TLAN. With this configuration, however,
a single Layer 2 switch remains a single point of failure.

Single server port network connections (dual-homing - non distributed)
The following figure illustrates a typical network 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 for
the highest reliability in a single CPU Call Server configuration. You must
partition the layer 2 switch into separate VLANs to keep the ELAN and
TLAN traffic on separate subnets
