Termination resistors in both the transmit and receive paths (100
ETS 300012, and ANSI T1.605) for all 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.
This parameter should be left in the default state for most applications.

The ATLAS 550 is capable of providing 1W (at 40 V) power on each BRI S/T interface to provide line
power (phantom power) to TE equipment. Set this parameter to
the S/T interface requires line power.
Do not enable line power on a BRI S/T interface configured for TE mode (Network
Term). Setting this parameter to
