Connecting Call Server 0 to Call Server 1

The CS 1000E redundant architecture allows for the separation of

Call Server 0 and Call Server 1. The two processors are connected by either a direct 100BaseT crossover cable or a carefully engineered Layer 2/VLAN infrastructure.

Campus Redundancy provides the ability to separate the CS 1000E Call Servers in a campus environment for “campus mirroring”. This feature enables two Call Servers, one active and one redundant, to be connected through an Ethernet network interface. Campus Redundancy can operate using any vendor’s Layer 2 switching products, in addition to the BayStack 470. The distance depends upon network parameter limitations specified in Communication Server 1000: System Redundancy (553-3001-307).
