Facility Test Calls

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 place a tone receiver test call:

1. Dial the FAC described in the introduction to this section and listen for dial

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:

Confirmation tone

Intercept tone

Reorder tone

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

6. To terminate the test call, hang up the station set used for testing.

The DTMR is connected. Go to

The port entered is not a TTR or the board is not

inserted (if a trunk, see above).

The DTMR is in use (call processing), the board is
