PRI Cabling
The peripheral side of the PRI network interface module connects to 
the endpoint using a cable with keyed RJ-45 connectors. Figure 2-5 
shows this cable. Because it uses a non-standard connector, Polycom 
Inc. does not support cables of this type that are fabricated by other 
vendors.

Keyed RJ-45 Cable, System to Network Interface Module
A standard RJ-45 to RJ-45 cables connects the PRI to the network. 
This is the same cable used by the Quad BRI network interface. 
Figure 2-6 shows this type of cable.
