Table C-3. Sync Data Port Configuration Options (4 of 5)

Port (DTE) Initiated Loopbacks: Disable (Factory 1) Both (Factory 2) Disable DTLB DCLB Both

Allows the initiation and termination of a local Data Terminal Loopback (DTLB) or remote Data Channel Loopback (DCLB) by the DTE connected to this port. (DTLB is equivalent to a V.54 loop 3, and DCLB is equivalent to a V.54 loop 2.) Control of these loopbacks is through the DTE interchange circuits as specified by the V.54 standard.

Disable – Disables control of local DTLBs and remote DCLBs by the DTE connected to this port.

DTLB – Gives control of the local DTLBs for this port to the DTE attached to this port. This loopback is controlled by the Local Loopback interchange circuit LL (CCITT 141).

DCLB – Gives control of the remote DCLBs for the far-end port connected to this port to the DTE attached to this port. This loopback is controlled by the Remote Loopback interchange circuit RL (CCITT 140). The far-end equipment must support in-band V.54 loopbacks.

Both – Gives control of local DTLBs and remote DCLBs to the DTE connected to this port.

Near-End Performance Statistics: Disable

Disable Maintain Send Both

Specifies whether the DSU/CSU maintains near-end performance statistics and sends performance report messages (PRMs) for a particular port.

Disable – Disables near-end performance statistics and does not send PRMs.

Maintain – Maintains near-end performance statistics for this port.

Send – Sends PRMs over the port’s EDL every second. Each PRM contains the performance statistics for the previous 4 seconds.

Both – Maintains near-end performance statistics and sends PRMs over the port’s EDL.

NOTES: – This configuration option is not available if EDL is disabled.

–If the local DSU/CSU is configured to send near-end performance statistics, then the remote device must be configured to maintain far-end performance statistics.

Far-End Performance Statistics: Disable

Disable Maintain

Specifies whether to monitor for far-end performance report messages (PRMs) and maintain far-end performance registers for a particular port.

Disable – Disables far-end performance statistics.

Maintain – Monitors the port’s EDL for PRMs and maintains far-end performance statistics.

NOTES: – This configuration option is not available if EDL is disabled.

–If the local DSU/CSU is configured to maintain far-end performance statistics, then the remote device must be configured to send near-end performance statistics.
