AT&T 518-600-016 manual Wiring a Voice Terminal for TWO VOICE-PAIRS

WIRING A VOICE TERMINAL FOR TWO VOICE-PAIRS

If an analog voice terminal requires either the Voice Announcement to Busy Voice Terminal feature or the Simultaneous Voice and Data feature, you need to assign two adjacent odd/even station jacks (01 and 02, 13 and 14, etc.) on an analog station module to that voice terminal. For Release 3, Form 1d, System Form-Station Planning shows which stations receive either option. For Feature Modules 1 and 2, the Master Planning Form gives this information. The numbers of the station jacks to which each of these stations should be connected are boxed on the form.

The wiring requirement for either of these features is that two voice-pairs (one pair from each jack) must be connected from the control unit to the voice terminal. Refer to Figure 2-6for an example of wiring a voice terminal for adjacent odd/even jacks. In this example, a bridging adapter (BR-241-B1) is used to connect both voice pairs to the voice terminal.

Note that in Figure 2-6,the wire from station jack 39 on the line module connects to the jack labeled “Even” on the bridging adapter. This is because the label on the bridging adapter refers to the default intercom number, which does not necessarily match the station jack number in terms of odd and even. Odd/even wiring refers to jack numbers, not intercom numbers.
