Diagnosing Phone Problems
No Dial Tone Analog Phone
1.
Log into the System Administration Tool and navigate to Maintenance Commands.
2. Establish the Location of the analog set using the Locate Extension maintenance
command.
3. Run the State <extension> command. You will get one of the following responses:
Idle, Busy, Manbusy, or Locked Out.
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.
