S/T Option Module.

MODULES (ST-BRI-4) > CONFIGURATION > LINE TERMINATION

Write security: 3; Read security: 5

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.

This parameter should be left in the default state for most applications.

MODULES (ST-BRI-4) > CONFIGURATION > PS1 LINE POWER

Write security: 3; Read security: 5

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 ON only if the TE equipment connected 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 ON in a TE configuration (Network Term) may result in damage to the module.

MODULES (ST-BRI-4) > TEST

Write security: 5; Read security: 5

These options initiate different types of tests and display test results.

MODULES (ST-BRI-4) > TEST > PRT

Write security: 5; Read security: 5

Identifies the port number. There are 4 available interfaces on the Quad BRI-S/T Option Module.
