Facility Test Calls
Issue 1 May 2002 5-17 555-233-143
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.
