Terminating Cables at Digital Telephone Locations
Terminate the digital telephone, single line phone, and playback device station cables on
four-conductor modular jack [six-conductor line jack unit in Europe] assemblies at the station
locations.
Do not mount the assemblies on the wall at this time; they will be wall-mounted later when the station
instruments are installed. See
Figure 15
and Figure 16 on
page 212
.
Newer 8528 and 8568 Digital Telephones
Unlike the 8520 and 8560 digital telephones, the newer 8528 and 8568 telephones use standard
RJ11 wiring configuration as defined in Telecommunications Industry Association (TIA) 968. See
Table 22 on page 112 for cable termination information.
