Foreign and surge voltage protections
In-circuit protection against power line crosses or lightning is not provided
on the SILC card. When the SILC card is used in TIE trunk applications in
which the cabling is exposed to outside plant conditions, an NT1 module
certified for such applications must be used. Check local regulations before
providing such service.

Functional description
The NT6D70 SILC card provides eight S/T four-wire full-duplex
polarity-sensitive interfaces to connect ISDN BRI-compatible terminals over
Digital Subscriber Loops (DSL) to the system. Each S/T interface provides
two B-channels and one D-channel and supports a maximum of eight
physical connections that can link up to 20 logical terminals on one DSL.
