SET LBO

Selects the line build out for the network interface.

 

 

 

 

In AUTO mode, the TSU 600 sets the LBO based

 

 

 

on the strength of the receive signal and displays

 

 

 

the selected value.

 

 

 

Choices: 0.0 dB, 7.5 dB, 15 dB, 22 dB, and Auto

 

 

 

To activate the -36 dB receiver sensitivity, set

 

 

 

the LBO to AUTO. This feature is useful in a

 

 

 

point-to-point application where no network

 

 

 

elements are involved. If a network element

 

 

 

such as a Smart Jack is installed on the circuit,

 

 

 

the LBO should be set to 0 dB.

 

 

 

 

 

 

INBAND

Sets unit to accept or reject the network interface

 

 

 

LPBCK

loop-up and loop-down codes as defined in ANSI

 

 

 

T1.403.

 

 

 

Choices: Accept, Reject

 

 

 

 

 

 

BIT STUFFING

When enabled, bit stuffing causes the TSU 600 to

 

 

 

 

monitor for ones (1s) density violations and insert

 

 

 

a one (1) when needed to maintain ones at 12.5%.

 

 

 

Choices: Enable, Disable

 

 

 

 

 

 

TR-08

The TR-08 submenu configures the unit for TR-08

 

 

 

 

applications. The submenu items and their

 

 

 

descriptions follow.

 

 

 

Alarm Report

 

 

 

Enables and disables the transmitting of alarm

 

 

 

reports.

 

 

 

Choices: SEND ALARMS, DISABLE ALARMS

 

 

 

Alarm Format

 

 

 

Sets the alarm frame format to 13 frames or 16

 

 

 

frames.

 

 

 

Choices: ORB-13, ORB-16

 

 

 

BPV Threshold

 

 

 

Sets the threshold for BPVs to trigger an alarm.

 

 

 

Choices: 10-4, 10-5, 10-6
