Termination resistors in both the transmit and receive paths (100
Ω
) are required (per CCITT I.430, ETSI
ETS 300012, and ANSI T1.605) for all Basic Rate ISDN (BRI) S/T interfaces operating in NT mode (User
Term) and TE mode (Network Term) in point-to-point applications. ANSI T1.605 provides examples of
S/T interfaces configured in a multi-point NT1 star operation. The NT1 star mode allows a single NT
device to support multiple T interfaces (TE devices). Custom cables are required for this type of
application, and are not available for purchase (from ADTRAN) for the ATLAS 550.

The ATLAS 550 is capable of providing 1W (at 40 V) power on each Basic Rate ISDN (BRI) S/T interface
to provide line power (phantom power) to TE equipment. Set this parameter to
to provide line power (phantom power) to TE equipment. Set this parameter to
ON
only if the TE
equipment connected to the S/T interface requires line power.
