SECTION 24 INTERCOM

24.1 DESCRIPTION

The intercom functions as an interface between the Switch and remote base station to aid in alignment of the system. The intercom allows technicians to communicate between the Switch and remote base station over one line pair while aligning a second pair. Then the lines are switched to align the first pair.

24.2 INSTALLATION

24.2.1 EQUIPMENT REQUIRED

1.Audio Oscillator, 600 ohm output

2.AC Voltmeter, HP400E or equivalent

24.2.2 INSTALLATION PROCEDURE

1.Insert the Switch Intercom in an open slot in a card rack. Shelf-1, Slot-3 is preferred.

2.Insert a 1 kHz tone at 0 dBm into the Rx portion of J702.

3.Verify 0 dBm ±1dB at U701, pin 7.

4.Insert the speaker/microphone in jacks J701 and J702.

5.Adjust R704 for maximum level out. (8V P-P across speaker jack J701).

6.Remove the tone.

7.Speak into the microphone in a normal voice and adjust R712 for -12 dBm ±3 dB at U703, pin 1.

8.Use the patch cord cables supplied in the installa- tion kit to patch from the Intercom RX to RX jacks to the transmit and receive jacks on the selected module (CIM). (Refer to VTM component layout.)

9.Adjust the volume knob on the front panel to the desired listening level.

NOTE: J703 can be jumpered on pins 1 and 2 to provide a 600 ohm load to the receiving line. The jumper may be placed on one pin only to provide a high impedance bridging input (refer to the component lay- out).
