Notes:
A common trouble on DID trunks, which reports no errors or alarms, occurs when 
the CO busies out the port (disconnects port). This situation occurs when the CO 
thinks there are problems with the DID port. In this case, no incoming calls are 
possible through this port. In addition to complaints received from outside callers 
trying unsuccessfully to call in, this problem can be diagnosed by listing 
measurements on lightly used trunks. If a particular port is detected as not in use, 
a call to the CO is necessary to get the connection back in service.
a. This condition occurs when the tone detector times out waiting for digits.
1 – Verify trunk administered wink/immediate-start parameter.
2 – Verify the dial type.
3 – Refer problem to the CO.
b. Rotary dial before wink – This condition occurs when the CO starts dialing 
before the PBX sends wink on a wink-start trunk. 1 – Verify trunk 
administered wink/immediate-start parameter.
2 – Refer problem to CO.
c. Rotary dial too early – This condition occurs when the CO starts dialing too 
soon after seizure on an immediate-start trunk.
1 – Verify trunk administered wink/immediate-start parameter.
2 – Refer problem to CO.
d. Rotary dial pulse during wink – This condition occurs when the CO sends 
rotary dial digits too soon after seizure on a wink-start trunk.
1. Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer to the 
appropriate test description and follow the recommended procedures.
2. Minor alarms on this MO may be downgraded to Warning alarms based on the values used in the 
set options command. If the Minor alarm is not downgraded by the set-options values, the Minor 
alarm is upgraded to a Major alarm if 75 percent of the trunks in this trunk group are alarmed.
