Telephone Connection Example

The 302C Attendant Console is used as an example telephone connection. This is typical of the 603E, 84xx (4-wire), and 94xx telephones. The maximum cabling distance for a console powered from the cabinet is 350 feet (100 meters) using

24 AWG (#5) (0.26 mm2) wire. The general steps to connect a telephone are:

1.Choose a device to connect such as a 302C Attendant Console.

2.Choose the port circuit pack, its carrier, slot number, and port; such as TN754B, cabinet 1, carrier C, slot 02, port 05.

3.Install cross-connect jumpers to wire the pins on the terminal to the pins on the port circuit pack. See Figure 5-2. This example is for the TN754B Digital Line circuit pack.
