Overview
The NT6D71 U Interface Line Card (UILC) supports the OSI physical layer
(layer 1) protocol. The UILC is an ANSI defined standard interface. The
UILC provides eight two-wire full duplex (not polarity sensitive) U interfaces
that are used to connect ISDN BRI compatible terminals over DSLs to the
Meridian 1. A description of the ISDN BRI feature is contained in Option
11C ISDN BRI Hardware Installation and Maintenance (553-3011-311).
