Connecting CP PM Call Server 0 to CP PM 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 CP PM
Call Servers in a campus environment for “campus mirroring”. This feature
enables two CP PM 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
(NN43001-507).
To separate the redundant CP PM Call Servers, the ELAN subnet and the
subnet of the High Speed Pipe (HSP) can be extended between the two
processors with an Ethernet switch, using Layer 2 protocol.
If the two CP PM Call Servers are collocated, they can be connected using a
standard CAT5e or CAT6 crossover cable, limited to 100 meters in length.
