Port Configuration Options

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, equivalent to a V.54 loop 3) or remote Data Channel Loopback (DCLB, equivalent to a V.54 loop 2) to be controlled by the DTE connected to this port.

NOTE: Control of these loopbacks by the DTE is done through the 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 interchange circuit RL (CCITT 140) ± Remote Loopback.

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 interchange circuit LL (CCITT 141) ± Local Loopback.

NOTE: 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 monitoring of interchange circuits from the DTE connected to this port.

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

RTS ± Monitors interchange circuit CA (CCITT 105) ± Request-to-Send (RTS). 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.

Rcv Yellow: Halt

Next None Halt Prev

Action on Network Yellow Alarm. Specifies the action taken on this port when a yellow alarm is received on the network interface.

None ± Makes the data port unaffected by yellow alarms received on the network interface.

Halt ± Stops the transmission of data on the port and disable the data port when yellow alarms are received on the network interface. When yellow alarms are received, all ones are sent on circuit BB(CCITT 104) ± Receive Data (RD) and circuit CB (CCITT 106) ± Clear-to-Send (CTS) is interrupted.
