The ADTRAN®NT1 ACE™provides the

network termination for 2B1Q ISDN basic

rate service. The NT1 ACE provides a 2B+D

basic rate interface between the subscriber’s

terminal equipment and the ISDN network.

Basic rate ISDN consists of two 64 kbps B

channels and a single 16 kbps D channel.

Connection to the ISDN network is made

with a U interface. Connection to the

subscriber’s terminal equipment is by an

S/T interface. The U and the S/T interfaces

conform to ANSI and CCITT standards and

perform all Layer 1 functions.

The NT1 ACE is designed with aesthetics as

well as functionality in mind. The unit is

enclosed in an attractive, durable plastic

housing appropriate for desk-top use. The NT1

ACE is powered by the wall-mount power

supply included with the unit. The wall-mount

power supply provides up to 8.9 W of power for

terminal equipment. The NT1 ACE monitors

the S/T interface for overcurrent fault condi-

tions. In the event of such a condition, the unit

automatically limits the amount of delivered

current until the fault condition is removed.

As many as eight passive bus devices may be

connected to the S/T interface of the NT1.

These connections can be in one of the

following two modes: multiple terminals within

50 meters of each other over the full 1,500

meter range of the interface, or multiple termi-

nals of arbitrary spacing within 200 meters.

Also, termination impedance options include

50 Ohm, 100 Ohm, or unterminated. The NT1

ACE is protected from lightning and harmful

line transients on the network interface.

Three LED status indicators on the NT1

ACE aid in fault isolation. Indicators display

the status for Power, Network Ready, Network

and Customer Errors.
