3 Extenders for 2-wire DCP endpoints
This chapter provides information on 2-wire voice and data terminals and digital
communications protocol (DCP) extenders. Extenders provide off-site employees
with the full feature set of the PBX.
2-wire DCP endpoints
Wire the tip and ring connections of 2-wire DCP endpoints to a TN2224B digital
line 2-wire circuit pack (or equivalent), similar to the 2-wire analog endpoints for a
TN747B analog line circuit pack.
The TN2224B supports 2-wire DCP sets only (not 4-wire).
The MM712 media module for the G700 Media Gateway is a 2-wire DCP
interface. The G700 Media Gateway supports 2-wire DCP sets only (not 4-wire).
!
CAUTION:
Except for auxiliary power, if necessary, these should be the only
connections to the modular wall jack. Do not bridge or parallel these
telephones.
Table 10 provides the pin-out configuration for 2-wire endpoints.
