Overview
The S/T Interface Line Cards (SILC) (NT6D70AA-48V North America,
NT6D70 BA -40 V International) provide eight S/T four-wire full duplex
interfaces that are used to connect ISDN BRI compatible terminals over DSLs
to the Meridian 1 system. A description of the ISDN BRI feature is contained
in Option 11C ISDN BRI Hardware Installation and Maintenance (553-
3011-311).
