The capabilities of survivable core servers are enhanced to support the connection of IP devices to the Processor Ethernet (PE) interface.

A survivable core server can use the PE interface to support IP devices, such as Branch Gateway, H.323 Gateways, IP Adjuncts, IP telephones, IP trunks, and SIP trunks. The survivable core server can provide the equivalent benefit of a survivable remote server. The survivable core server can be duplicated, providing more redundancy to the survivability of the system.

For PE on duplex servers to work, assign the PE interface to the PE Active server IP address and not the server unique address. The NIC assigned to the Processor Ethernet interface must be on a LAN connected to the main server.
