ISDN BRI (U Interface) Adapter Module
ISDN BRI (U Interface) is a 2-wire BRI interface obtained from an ISDN
provider or local exchange. It cannot be directly connected to the network and
requires connection to an NT1 (Network Terminating unit, type 1), an external
device provided by the phone company. The NT1 accepts a 2-wire signal and
converts it to a 4-wire signal that sends and receives to and from devices within
the home or a business
Note:
This module is designed to accept an RJ-48 connector; however, it
is compatible with an RJ-45 cable connector.
