The following Facility Test Calls are described below:
■
‘‘Trunk Test Call’’
■
‘‘Touch-tone (DTMF) Receiver Test Call’’
■
‘‘Time Slot Test Call’’
■
‘‘System Tone Test Call’’
Trunk Test Call
The trunk test call accesses specific Tie or CO trunks. DID trunks cannot be
accessed.
To place a call:
1. Dial the Facility Test Call Feature Access Code and listen for dial tone.
The Feature Access Code is set on the Feature Access Codes screen.
2. Dial the 6-digit port number PCSSpp
The channels on a DS1 trunk are addressed by using the channel number
for the port number.
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.
