DTMR Test Call
This call accesses and tests the dual tone multifrequenc y receivers (DTMR-PTs)
located on TN420 and TN748 Tone Detector circuit p acks. These tone receivers
are also known as touch tone receivers (TTRs). Before making the test c all, use
list configuration to determine the location of the TN420 or TN748 that you
which to test.
To place a tone receiver test call:
1. Dial the FAC described in the introd uction to this section and listen for dial
tone.
2. Dial the seven-digit port loc ation UUCSSpp of one of the four DTMR ports
located on a Tone Detector circuit p ack:
C = Carrier number (A=1, B= 2, C=3, D=4, E= 5)
SS = Slot number (00-20)
pp = Port circ uit number (DTMR ports are numbered 01, 02, 0 5, and 06.
3. Listen for one of the following tones:
4. Dial the sequence 1234567890*#.
If the sequence is entered a nd received c orrectly, dial tone is returned and
another test call can b e made. If the test fails, intercep t tone is returned. A
failure may indicate a faulty DTMR port or circ uit pack, a faulty voic e
terminal, or an error in the entry of the sequenc e.
5. To test another DTMR, repeat steps 2 through 4.
6. To terminate the test call, hang up the station set used for testing.
TDM Bus Time Slot Test Call
The time slot test call connects the voi ce terminal to a spec ified time slot on the A
or B TDM Bus of a specified p ort network. To connect to any out-of-service time
slots, refer to the ‘‘Out-of-Service Time Slot Test Call’’ section.
To test a specific time slot on the TDM bus of a spec ific port network:
1. Dial the FAC described in the introd uction to this section and listen for dial
tone.
Confirmation tone The DTMR is connected. Go to step 4.
Intercept tone The port entered is not a TTR, (if a trunk, see
above), or the board is no t inserted.
Reorder tone The DTMR is in use, (call processing), the
board is busied out, or inter-PN resources are
unavailable for the call.
Dial tone The port is a trunk. See the preceding section.
