Net DCLB: Disab (Factory 1)

Both (Factory 2)

Next Disab V.54 FT1

Both Prev

 

 

Network Initiated DCLB. Allows the initiation and termination of a Data Channel Loopback (V.54 loop 2) by the receipt of a V.54 DCLB-actuate sequence or DCLB-release sequence from the network or far-end device. The sequences may be either V.54 or FT1 (ANSI) compliant sequences.

Disab – Ignores the DCLB-actuate and DCLB-release sequences for this port.

V.54 – Enables DCLB-actuate and DCLB-release sequences that comply with the V.54 standard for “Inter-DCE signaling for point to point circuits.”

FT1 – Enables DCLB-actuate and DCLB-release sequences that comply with the ANSI T1.403, Annex B standard for “In-band signaling for fractional-T1 (FT1) channel loopbacks.”

Both – Enables DCLB-actuate and DCLB-release sequences that comply with either the ANSI or V.54 standard. The type of actuate and release sequences do not have to match.

Port LB: Disab (Factory 1) Both (Factory 2)

Next Disab DTLB DCLB Both Prev

Port (DTE) Initiated Loopbacks. 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.

Disab – 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.

All Ones: Both

Next Disab DTR RTS Both Prev

Send All Ones on Data Port Not Ready. Specifies the conditions on the data port that determine when valid data is not being sent from the DTE. When this condition is detected, all ones are sent to the network on the DS0 channels allocated to the port.

Disab – Disables the monitoring of interchange circuits from the DTE connected to this port.

DTR – Monitors the DTE Ready interchange circuit CD (CCITT 108/1/2). When DTR is interrupted, all ones are sent to the network.

RTS – Monitors the Request-to-Send interchange circuit CA (CCITT 105). When RTS is interrupted, all ones are sent to the network.

Both – Monitors both DTR and RTS. If either is interrupted, all ones are sent to the network.

NOTE: If the Port Type configuration option is set to X.21, set this configuration option to RTS or Disab.
