3. Configuration Options

Table 3-7. T1 Network Physical Interface Options (3 of 4)

Network Initiated DCLB

Possible Settings: Disable, V.54_&_ANSI

Default Setting: V.54_&_ANSI

Allows the initiation and termination of the Data Channel Loopback (DCLB V.54 Loop 2) to be controlled by the receipt of a DCLB-actuate or DCLB-release sequence (either V.54 or FT1-ANSI compliant) from the network on the DS0s used for the network frame relay link. When enabled and a DCLB-activate sequence is received, the unit initiates a DCLB on the network interface. When a DCLB-release sequence is received, the DCLB is stopped.

Disable – DCLB-actuate and DCLB-release sequences are ignored.

V.54_&_ANSI – DCLB-actuate and DCLB-release sequences that comply with either V.54 or ANSI T1.403, Annex B standard will be recognized and will control initiation and termination of a DCLB for the network frame relay link. The actuate and release sequences do not need to match (for example, a DCLB started with a V.54 actuate sequence can be stopped with an FT1 release sequence).

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 network 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.
