Turn the power on. Verily the AC Power lamp on the back of the power supply glows. Inside
the TC4001 on the VC7166
MI0
board, an LED marked 12V and, to its right, two segments of
another LED (indicating the presence of 5 VDC and
-3
VDC) should also glow.
After a few seconds:
Telecenter IV
should show on the display, provided that there is
no call-in activity on the remote lines.
Pick up the test phone and verily the presence of dial tone; then press any key and verify dial
tone stops. Place the phone on-hook.
Take two phones off-hook simultaneously and verily each receives dial tone, then place one
back on-hook.
Dial an administrative phone. Verily it rings and, when answered, supports regular telephone
conversation.
Dial a speaker that is not in the privacy mode. Verify a talk and listen path exists through the
speaker.
Verify Call-ins can be produced in the following three ways: The type of call-in produced
depends on programming but can be simulated as follows:
Normal
Call-in:
Ground the T terminal on the desired speaker control circuit.
Emergency Call-in: Ground the T terminal through a
1.5K
resistor.
Normal Call-in:
Pick up a multi-link staff phone.
Dialing #OO and verily All-Page works. Adjust the power amplifier output if necessary.
If a Director Panel with Emergency Announce Button is included, verify it overrides All-
Page and adjust the output level at the Control Panel if necessary.
Activate the clock and verily speakers receive time zone tones. Types of tones and speaker
zone groupings depend on programming.
Call the speaker of stations with staff phones and speakers and verify that the communication
path moves from the speaker to the phone when the phone is taken off-hook. If the station is
not programmed for speaker first answering (A:7), use the ## function.
If graphic displays are installed, verily they are connected correctly to drive GRl to show call-
ins and/or to drive GR2 to show lines in use.
If a TC4400 Call Control Console is installed, check it according to the procedure in its
manual, KI-1559.
