Table 3-21. ISDN PRI DBM Physical Interface Options (9128) (2 of 3)

Line Build Out (LBO)

Possible Settings: 0.0, –7.5, –15, –22.5

Default Setting: 0.0

Specifies the line build out for the signal transmitted to the ISDN.

0.0, –7.5,–15,–22.5– Specifies line build out in dB.

Network Initiated LLB

Possible Settings: Enable, Disable

Default Setting: Enable

Allows the initiation and termination of the line loopback (LLB) to be controlled by the receipt of LLB-Actuate and LLB-Release commands from the ISDN.

Enable – LLB is controlled by LLB-Actuate and LLB-Release commands. Receiving a LLB-Actuate command causes the system to enter a line loopback (provided an LLB can be performed in the system’s current state). Receiving an LLB-Release command terminates the LLB.

Disable – The system ignores the LLB-Actuate and LLB-Release commands.

NOTE: When disabled, the system is not in compliance with ANSI T1.403 or

AT&T TR 62411.

Network Initiated PLB

Possible Settings: Enable, Disable

Default Setting: Enable

Allows the initiation and termination of the payload loopback (PLB) to be controlled by the receipt of PLB-Actuate and PLB-Release commands from the ISDN.

Display Conditions – This option only appears when Line Framing Format is set to

ESF.

Enable – PLB is controlled by PLB-Actuate and PLB-Release commands. Receiving a PLB-Actuate command causes the system to enter a payload loopback (provided a PLB can be performed in the system’s current state). Receiving a PLB-Release command terminates the PLB.

Disable – The system ignores the PLB-Actuate and PLB-Release commands.

NOTE: When disabled, the unit is not in compliance with ANSI T1.403 or

AT&T TR 54016.

ANSI Performance Report Messages

Possible Settings: Enable, Disable

Default Setting: Disable

Specifies whether ANSI T1.403 compliance performance report messages (PRMs) are generated and sent to the ISDN over the ESF facility data link every second.

Display Conditions – This option only appears when Line Framing Format is set to

ESF.

Enable – Generates and sends PRMs.

Disable – Does not generate and send PRMs.
