NT1R20 Off-Premise Station Analog Line card
The NT1R20 Off-Premise Station (OPS) Analog Line card is an intelligent
eight-channel analog line card designed to be used with 2-wire analog
terminal equipment such as analog (500/2500-type) telephones and analog
modems. Each line has integral hazardous and surge voltage protection
to protect the system from damage due to lightning strikes and accidental
power line connections. This card is normally used whenever the phone
lines leave the building in which the switch is installed. The OPS line card
supports message waiting notification by interrupting the dial tone when
the receiver is first picked up. It also provides battery reversal answer and
disconnect analog line supervision and hook flash disconnect analog line
supervision features.
