INTERFACES (DSX)

View the integrated DSX interface status and configure T1 parameters from this menu.

INTERFACES (DSX) > CONFIG

Configure the various DSX parameters and enable/disable loopbacks from this menu.

INTERFACES (DSX) > CONFIG > FORMAT

This sets the frame format for the DSX interface. The setting must match the frame format of the circuit to

which the interface is connected. Choices are

ESF, SF (D4). Extended Superframe (ESF) provides a

non-disruptive means of full-time monitoring on the facility datalink (FDL). Default is

ESF.

INTERFACES (DSX) > CONFIG > LINE CODE

This sets the line code for the DSX interface. The setting must match the line code of the circuit to which

the interface is connected. Choices are

B8ZS (bipolar with 8-zero substitution) and AMI (alternate mark

inversion). Default is

B8ZS.

INTERFACES (DSX) > CONFIG > EQUALIZATION

Select the line build out for the DSX1 interface. The choices are 0 dB, 266 FT, 399 FT, 533 FT, 655 FT, or

-7.5 dB

. Default is 0 dB. The 7.5 dB setting is provided for terminal equipment that has trouble recovering

a full 0dB level signal (typically one with a DS1 long haul line interface).

INTERFACES (DSX) > CONFIG > CSU LPBK

Choices are ENABLE, DISABLE, and DISABLE ALL. Default is ENABLE. This allows the unit to either respond

or not respond to CSU loop up commands.

INTERFACES (DSX) > CONFIG > RX SENSITIVITY

Configures the sensitivity of the T1 receiver for this interface to provide increased sensitivity for long-run

T1 applications. Choices are

AUTO, -36 dB, and -10 dB.

INTERFACES (DSX) > STATUS

Displays the T1 status including performance data and alarm histories.

INTERFACES (DSX) > STATUS > PERFORMANCE

Displays the T1 performance data.

INTERFACES (DSX) > STATUS > PERFORMANCE > CURRENT AND TOTALS

Provides current (15-minute window) status on key performance measures as specified in ANSI T1.403

and AT&T TR 54016 as well as historical statistical totals for the integrated DSX port.

INTERFACES (DSX) > STATUS > PERFORMANCE > CURRENT AND TOTALS > INTERVAL

Identifies the interval (CURRENT or TOTAL) for the listed performance statistics.
