Power consumption is +5V at 800 mA and -48V at 480 mA.

Power consumption is +5 V at 800 mA and –48 V at 480 mA.

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.

A logical terminal is any terminal that can communicate with the system
over a DSL. It can be directly connected to the DSL through its own
physical termination or be indirectly connected through a common physical
termination.
