list testcalls

Last Updated : Apr 05, 2018 |

Use list testcalls to generate an Automatic Transmission Measurement System (S) report. S allows the voice and data trunk facilities to be measured for satisfactory transmission performance. The performance of the trunks is evaluated according to measurements produced by a series of analog tests (test analog-testcall) and are compared against user-defined threshold values. The purpose of the report is to provide measurement data to help determine the quality of trunk lines. The measurement report contains data on trunk signal loss, noise, singing return loss, and echo return loss.

The measurements are produced by a set of analog trunk tests (test analog-testcall). The tests are initiated by a maintenance demand test or by a set of scheduled tests. The largest portion of these measurements are generated through scheduled testing during system quiet hours (hours where the traffic volume is low). Each trunk test performed by the system stores the results in a database. The trunk measurements in this database reflect the state of each trunk at the time of its last test.

The test analog-testcall test aborts when attempting a test call on these trunk groups:

  • ISDN-PRI: The S Summary Report (list testcalls command) shows a 0 in the in the Busied Out Trunks field when test analog-testcall is run on an ISDN-PRI trunk.

  • SIP

  • DID

  • Any incoming trunk group (transmission tests can only be run on outgoing trunks).

detail

Detailed measurement report displayed.

summary

Summary measurement report displayed.

grp #

Measurements for a specific trunk group displayed. When used with the to-grp option, this option is the starting trunk group in a range of user-specified trunk groups.

to-grp #

Measurements for all trunk groups from 1 to the specified to-grp trunk group are displayed. When used with the grp option, this option is the ending trunk group in a range of user-specified trunk groups.

mem #

Measurements for a specific trunk group member displayed. When used with the to-mem option, this option is the starting trunk group member in a range of user-specified trunk group members.

to-mem #

Measurements for all trunk group members from 1 to the specified to-mem trunk group member displayed. With mem, this option is the ending trunk group member in a range of user-specified trunk group members.

port-location

Measurements for a specific trunk circuit (port) displayed.

result-identifier

Filter out the measurement results that do not match the user-specified result. Only measurement results that match the specified result are displayed. Examples of results are pass, marg, fail.

not-result-identifier

Filter out the measurement results that do match the user-specified result. Only measurement results that do not match the user specified result are displayed. Examples of results are pass, marg, fail.

count n

Specify the number of records displayed.

Field

Description

Group

Trunk group number selected.

Type

Trunk group type.

Vendor

Vendor of this trunk group.

TTL Type

Kind of test line for this trunk group.

Threshold Values

The list of marginal and unacceptable threshold values defined on the trunk group form.

The following fields display on the lower section of the form. Many of the column headings contain the abbreviations FE for far end and NE for near end. These abbreviations define which end took the measurements.

Trk Mem

The trunk member within the trunk group.

Test Date

The month and day this trunk was tested.

Test Time

The time of day this trunk was tested.

Tst Rslt

This field describes the results of the trunk transmission test.

1004Hz-loss Min

Far-to-near and near-to-far measurements of 1004-Hz loss from low-level tone.

1004Hz-loss Max

Far-to-near and near-to-far measurements of 1004-Hz loss at 0 dBm.

Loss dev at 404Hz

Transmission tests at low frequency. These tests measure a maximum positive and negative deviation of +9 and -9 dB from the 1004-Hz loss measurements.

Loss dev at 2804Hz

Transmission tests at high frequency. These tests measure a maximum positive and negative deviation of +9 and -9 dB from the 1004-Hz loss measurements.

C-msg Noise

Maximum noise interference (in dBrnC: decibels above reference noise, which is B(EQ)10 sup -12E(EQ) watts) terminating on a voice terminal within the voice-band frequency range (500 to 2500 Hz) between 15 and 55 dBrnC.

C-ntch Noise

Maximum signal-dependent noise interference on a line between 34 and 74 dBrnC.

SRL-LO

Singing return loss from 0 to 40 dB between the sum of the circuit (repeater) gains and the sum of the circuit losses. SRL-LO occurs most often in the frequency range of 200 to 500 Hz.

SRL-HI

Singing return loss from 0 to 40 dB between the sum of the circuit (repeater) gains on a circuit and the sum of the circuit losses. SRL-HI occurs most often in the frequency range of 2500 to 3200 Hz.

ERL

Echo return loss from 0 to 40 dB between the level of signal strength transmitted and the level of signal strength reflected. ERL occurs most often in the frequency range of 500 to 2500 Hz.
