—————————— End of Procedure ——————————
Connect off-premise analog (500/2500-type) telephones through an
NTAK92AA Off-Premise Protection Module. Each module can connect up
to four analog (500/2500-type) telephones and can interface with one of the
following:
•
NT1R20 Off-Premise Station Analog Line Card
•
NT8D03 Analog Line Card
•
NT8D09 Message Waiting Line Card
The message waiting line card produces -150 volts which is considered
hazardous on off-premise telephones. Make sure that the -150 V is
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 Overlay 10.
Refer to the X11 Software guides for information about Overlay 10.
Do not assign a Class of Service of LPA or MWA to an off-premise
telephone.
