Multifrequency sender cards

Procedure 5

Testing multifrequency sender cards

Use this procedure to test a multifrequency sender (MFS) card or the MFS function of an NT8D17 Conference/TDS card.

1Log into the system: LOGI (password)

2Test and enable an MFS loop:

LD 46 MFS loop

(on the NT8D17 Conference/TDS card, the TDS/MFS loop is the even loop of the conference/TDS loop pair)

Note: The conference/TDS card is not enabled automatically when it is inserted. You must enable the card with the command ENLX. (This command is used in LD 34 and LD 46 to address even loops and in LD 38 to address odd loops.) Enabling the loops with the command ENLL does not enable the hardware for the card.

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

3Access the system from a maintenance telephone; then enter:

LD 46

Give the system approximately 20 seconds to load the program.

See “Communicating with the Meridian 1” in the Software Input/Output: Administration (553-3001-311) for details on accessing the system from a maintenance telephone.

4Obtain 10-second bursts of digits 1 to 9, 0, and 11 to 15 (in that order) for all digits on the specified loop:

TONE loop ALL

Each burst should sound different. If the bursts do not sound different, replace the card.

5End the session in LD 46:
