Phone Rings When Call Should Go To Attendant
If an incoming call is detected while all attendant lines are busy, the TClV searches up
through physical numbers from the last Attendant line until an available administrative line
takes the call or it arrives at the physical number of a line that is not administrative. Then it
will return to the first Attendant line and repeat the search process.
There are not enough Attendant lines to handle incoming call traffic if overflow causes the
TCIV to send calls to administration phones other than the Attendant.
If the TCN fails to find an Attendant line or administrative phone to answer an incoming call,
it temporarily ignores the call and the caller will continue to hear ringing.
Location Code 64000 is not programmed to the proper physical number or a trunk is pro-
grammed with the A: attributes for DIL instead of AAI.
False Call-ins After All-Call or Time Tones
step 1. C h e c k the amplifier gain adjustment. If too high, the amplifier will clip the signal and cause
this symptom.
Step 2. Check each side of the amplifier to common signal ground. Make an all-call and press the
three bottom keys on the phone. Each side of the output must be within
1 volt ac of the
other. If not, a short or leakage to ground exists. Check each speaker line individually.
Alternative Method: Use the diagnostic function #73. disconnect the VCM2 and insert
meters in its place. Advance 1 physical number at a time and
check the readings.
step 3.
Step 4.
Step
5.
Check the amplifier for possible oscillations. Disconnect the amplifier input & repeat Step 2.
Perform RP2 adjustment procedure.
If the preceding steps don’t prevent the false call-ins, unplug the SC25 flat cable from the
MIO. If this eliminates the false call-ins, plug the SC25’s in one at a time to find out which, if
any are defective.
