Quad BRI Cabling
The Quad BRI network interface module connects to the endpoint
using a cable with one keyed RJ-45 connector and one standard
RJ-45 connector. Figure 2-3 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.
