3. Listen for one of the following tones:
■ Dial Tone or Silence—trunk is connected. Go to Step 4. If you hear a
dial tone, it is coming from the far end. If the far end has been
disabled, you do not hear dial tone. However, depending on far-end
administration, you may still be able to dial digits. All digits dialed
after the port number are transmitted using end-to-end DTMF
signaling; therefore, if the trunk being tested is a rotary trunk, it is not
possible to break dial tone.
■ Reorder Tone—trunk is busy or maintenance busy.
■ Intercept Tone— a trunk or touch-tone (DTMF) receiver has not
been accessed.
4. Place a call. Even if you do not hear a dial tone, you may still be able to dial
digits, depending on the administration of the far-end switch.
All digits dialed after the port number are transmitted using end-to-end
DTMF signaling; therefore, if the trunk being tested is a rotary trunk, it will
not be possible to break dial tone.
If the call does not go through (that is, no ringing), determine if the trunk
circuit pack has been removed.
Touch-tone (DTMF) Receiver Test Call
The touch-tone (DTMF) receiver call accesses and tests the four touch-tone
(DTMF) receivers located on the Tone Detector circuit pack. To place the call:
1. Dial the Facility Test Call Feature Access Code (administered on the
Feature Access Codes screen), and listen for dial tone.
2. Dial the 6-digit port number "PCSSpp":
3. Listen for one of the following tones:
■ Confirmation Tone—touch-tone (DTMF) receiver is connected. Go
to Step 4.
■ Reorder Tone—touch-tone (DTMF) receiver is busy.
■ Intercept Tone—a touch-tone (DTMF) receiver or trunk has not been
accessed.
P = Port network number (01 for PPN or 02 or 03 for EPN)
C = Carrier number (A=1, B=2, C=3, D=4, E=5)
SS = Slot number (01—20)
pp = Touch-tone (DTMF) Receiver Port number (01, 02, 05, or 06)
