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 is
not 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 TN744D Tone Detector circuit pack. To place the
call:
1. Dial the Facility Test Call Feature Access Code (for example, 197, see
Note), and listen for dial tone.
NOTE:
The Feature Access Code (FAC) is administered on the Feature
Access Codes Form. The 197 FAC code used here is an example.
