DTMR Test Call
This call accesses and tests the dual-tone multifrequency receivers (DTMR-PTs)
located on TN420 and TN748 Tone Detector circuit packs. These tone receivers
are also known as touch-tone receivers (TTRs). Before making the test call, use
list configuration to determine the location of the TN420 or TN748 that you want
to test.
To place a tone receiver test call:
1. Dial the FAC described in the introduction to this section and listen for dial
tone.
2. Dial the seven-digit port location UUCSSpp of one of the four DTMR ports
located on a Tone Detector circuit pack:
C = Carrier number (A = 1, B = 2, C = 3, D = 4, E = 5)
SS = Slot number (00 – 20)
pp = Port circuit number (DTMR ports are numbered 01, 02, 05, and 06.
3. Listen for one of the following tones:
4. Dial the sequence 1234567890*#.
If the sequence is entered and received correctly, dial tone is returned and
another test call can be made. If the test fails, intercept tone is returned. A
failure may indicate a faulty DTMR port or circuit pack, a faulty voice
terminal, or an error in the entry of the sequence.
5. To test another DTMR, repeat step 2 through step 4.
6. To terminate the test call, hang up the station set used for testing.
Confirmation tone The DTMR is connected. Go to step 4.
Intercept tone The port entered is not a TTR or the board is not
inserted (if a trunk, see above).
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.
