NT6D71 UILC line card
to connect ISDN BRI-compatible terminals over Digital Subscriber Loops
(DSL) to the CS 1000. For more information on ISDN BRI, see
A UILC can reside in a Media Gateway or Media Gateway Expansion. A
maximum of four UILCs are supported in a Media Gateway and Media
Gateway Expansion.

Functional description
Each U interface provides two B-channels and one D-channel and supports
one physical termination. This termination can be to a Network Termination
(NT1) or directly to a single U interface terminal. Usually, this physical
termination is to an NT1, which provides an S/T interface that supports up
to eight physical terminal connections. The length of a DSL depends on the
specific terminal configuration and the DSL wire gauge; however, it should
not exceed 5.5 km (3.3 mi).
The main functions of the UILC are as follows:
•
provide eight ISDN U interfaces conforming to ANSI standards
•
support point-to-point DSL terminal connections
•
provide channel mapping between ISDN BRI format (2B+D) and system
bus format
•
multiplex four D-channels onto one timeslot
