The two processors are connected by eithera direct 100BaseT crossover cable or a carefully engineered Layer 2/VLANinfrastructure.Campus Redundancy provides the ability to separate the CS 1000E CP PMCall Servers in a campus environment for “campus mirroring”. This featureenables two CP PM Call Servers, one active and one redundant, to beconnected through an Ethernet network interface. Campus Redundancy canoperate using any vendor’s Layer 2 switching products, in addition to theBayStack 470. The distance depends upon network parameter limitationsspecified in Communication Server 1000: System Redundancy(NN43001-507).To separate the redundant CP PM Call Servers, the ELAN subnet and thesubnet of the High Speed Pipe (HSP) can be extended between the twoprocessors with an Ethernet switch, using Layer 2 protocol.If the two CP PM Call Servers are collocated, they can be connected using astandard CAT5e or CAT6 crossover cable, limited to 100 meters in length.
