End of Procedure

Connecting an off-premise telephone

Connect off-premise analog (500/2500-type) telephones through an NT1R20 Off-premise Line card or NTAK92AA Off-Premise Protection Module. Each NTAK92AA module can connect up to four analog (500/2500-type) telephones and can interface with the NT8D09 Message Waiting Line card.

DANGER OF ELECTRIC SHOCK

The message-waiting Line card produces -150 volts, which is considered hazardous on off-premise telephones. Make sure that the -150 volts are disabled on off-premise telephones.

The voltage is disabled when the telephone’s Class of Service (CLS) is Message Waiting Lamp Denied (LPD) and Message Waiting Denied (MWD) in LD 10.

Refer to the Software Input/Output: Administration (553-3001-311) for information about LD 10.

Do not assign a Class of Service of LPA or MWA to an off-premise telephone.
