This configuration also improves the availability of the circuit switched telephony traffic on this
site because, only half of the circuit-switched telephony located in the Atlanta site is affected by
an IPSI failure.
Note:
Note:
With the addition of an additional port network, there will be increased loads on
the media processor circuit packs, as they now must support the
inter-port-network traffic generated by the circuit-switched endpoints. As a result,
the traffic-engineering calculator should be applied to this configuration to
determine the required number of Media Processors.
