NOTE:
Only 1 pair of wires is available for emergency transfer, and 1 pair of wires
is available for attendant console power.
The wiring procedures are the same for most of the DEFINITY System telephones
and other equipment.
This chapter provides wiring examples of these similar installation procedures.
These are examples only and actual wiring procedures may vary at each site.
The system can connect to all DTE terminals. The system can have RS-232 (or
EIA-232) or DCP interfaces.
All wiring pinouts for port circuit packs are in the tables at the end of this chapter.
Refer to Figure 1-19 on page 1-37
for punch-down information for common circuit
packs. The figure shows the colors of the punch-downs and is best viewed from
CD-ROM or on-line.
After installing the hardware, the data for the system and telephone features is
administered. These procedures are provided in

Telephone Connection Examples
The 302C1 Attendant Console describes a typical telephone connection. This
information is typical of the 603E, 84xx (4-wire), and 94xx telephones. The
attendant console always requires auxiliary (adjunct) power (-48 VDC). See
Figure 1-25
. Only 1 console can be powered by the system through the AUX
connector. The primary console should be powered from the system so it has the
same power failure backup as the system.
The maximum cabling distance for the console powered from the cabinet is
350 feet (100 meters) using 24 AWG (#5) (0.26 mm
2
) wire.
The general steps to connect a telephone are:
1. Choose a device to connect such as a 302C1 Attendant Console.
2. Choose the port circuit pack and its carrier and slot number, such as
TN754B, Cabinet 1, Carrier A, Slot 06.
3. Choose a port circuit on the port circuit pack, such as Port 05.
