If the response is Idle:
• Connect a known good telephone set to the wiring frame.
• If the phone works then the problem is with the wiring from the frame to the set or it is the set.
• Disconnect the suspected set and connect a known good set into the terminal jack.
- If the test set works then the faulty set should be replaced.
- If the set does not work then the problem is in the wiring from the frame already tested
or the jack.
• Check that the wiring in the jack is correct
- If the wiring is incorrect then make the adjustment required and try the known good set
again.
- If the set still does not work then the problem is in the wiring.
• Check the wiring from the known good point at periodic intervals.
If the Response is Busy:
• Is the telephone engaged in a call?
- If Yes then the phone is functioning normally.
- If No then the phone is not functioning normally; take the following steps:
• Disconnect the wiring going towards the phone at the internal frame.
• Connect a known good telephone to the internal frame wiring and verify that there is dial
tone.
- If there is dial tone then there is a fault in the wiring.
- If there is no dial tone then it could be the D-type connector (Amphenol) cable or a fault
with the ASU. Verify the integrity of the Amphenol by changing it out.
If the Response is Manbusy:
• Find out why the circuit was busied out.
• Run the RTS <location id> command to return the circuit to service.
If the Response is Locked Out:
• Disconnect the wiring going towards the phone at the internal frame.
• Connect a known good telephone to the internal frame wiring that connects to the Analog
Service unit or peripheral cabinet and verify if there is dial tone.
• If there is dial tone, then there is a fault in the wiring. If there is no dial tone:
- For an analog phone it could be the D-type connector (Amphenol) cable or a fault with
the ASU. Verify the integrity of the Amphenol by changing it out.
CAUTION: If you change the Amphenol connector this will affect all users who
are connected to that ASU.
