TTP35: Dial Tone Does Not Stop after the

No Ring Sound Occurs after the

Dialing Completes

Initial Actions
Make sure that you have performed the
actions in TTP33: Control Panel Does Not
Communicate with Central Station by
Telephone on page 72.
Does the dial tone continue after the entire number is
dialed?
Using RPS or your D5200 Programmer, select
GV2MAIN Panel Wide Parameters Phone and
determine which of the four phone location numbers is
the primary central station phone number. If a backup
phone number is used, determine which phone
location number is the backup number. Verify the
primary and backup numbers.
Are the primary and backup numbers correct?
Enter the correct number or numbers and
repeat the test.
Is the control panel connected to a PBX system?
Enter C before the primary and backup
numbers to add a three-second pause before
the dialing begins.
A PBX system requires the user to enter a digit
on the phone (typically "9") to access an outside
line.
Enter C between the first and second digits of the
primary and backup numbers to add a three-second
pause between the PBX dial tone and the telco dial
tone before the dialing begins.
Replace the control panel. Repeat the test.
Does the new control panel operate properly?
The phone line connected to the control panel does
not operate correctly. Refer the customer to the local
phone company.
You cannot validate correct operation of the
phone line by measuring voltage during the
communication sequence.
The problem is solved.
