Configuring ISDN BRI hardware
Note 1: Power Source 1 (PS1): Up to 2 Watts of power is supplied by
the SILC to the terminals on the DSL. This power is simplexed over the
TX and RX pairs provided by -48 V (-40 V for Europe) supply on the
SILC. The RX pair is positive with respect to the TX pair.

U interface specification
The U interface uses a 2-conductor, twisted pair cable terminated with
an RJ-45 type jack. An RJ-45 type jack on the NT1 device connects the
terminal to the DSL using this twisted pair cable.
