Nortel Networks 553-3001-211 manual Cnfc loop, Cnfc MAN loop c, Cnfc Step

Acceptance tests Page 89 of 894

4Test the conference loop for channel, group, and switching faults:

CNFC loop

If the conference loop passes the tests, the output is OK.

If the system response is other than OK, see the Software Input/Output: Administration (553-3001-311) to analyze the messages.

5Prepare the system for a manual conference call on a specified loop:

CNFC MAN loop c

Where “c” is the manual conference group (1-15)

A manual conference test is performed by stepping through conference channels and groups, listening for noise that indicates a faulty card.

The manual conference test can be performed through a system terminal or BCS maintenance telephone. If commands are entered from a maintenance telephone, this telephone automatically becomes part of the manual conference call.

Only one manual conference call is allowed at one time. A manual conference consists of only two telephones, where one telephone acts as a signal source while the other acts as a listening monitor.

After you enter the CNFC command, any two telephones (one may already be the maintenance telephone) dialing the special service prefix code (SPRE) and the digits 93 will enter the manual conference call. The prime directory number (PDN) indicator, if equipped, will light on each telephone.

Going on-hook takes the telephone out of the manual conference call, and the test must be restarted.

See LD 38 in the Software Input/Output: Administration (553-3001-311) for more detailed information on using this command.

6Test various channels and conference groups audibly with the command

CNFC STEP

When stepping through channels and groups, a clicking followed by silence is normal. Any distortion or other noises indicates a faulty card.

Once the CNFC STEP command has been entered, entering C on the system terminal or maintenance telephone steps through the conference channels. Entering G steps through the conference groups. There are 15 channels per group and 15 groups per conference card.

Entering an asterisk (*) and END stops the test.
