Quad BRI Network Adapter TA Connections
The Quad BRI network adapter supports ISDN BRI networks. It provides the S/T interface to a BRI NT1 device
in an ISDN network. The board includes an IMUX, enabling you to achieve higher line rates by connecting up to
four BRI lines. Each BRI line requires an NT1 interface.
The NT1 interface may be provided by the ISDN service provider.
With PBX systems, the NT1 interface is a component of the system.
The illustration below shows the back of the PC with a Quad BRI network adapter card installed:
