Configuration Options

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

Send All Ones on Data Port Not Ready: Both

Disable DTR RTS Both

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.

Disable – 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 Disable.

Action on Network Yellow Alarm: Halt

None Halt

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 disables the data port when Yellow Alarms are received on the network interface. When Yellow Alarms are received, all ones are sent on the Received Data interchange circuit BB (CCITT 104). The Clear-to-Send interchange circuit CB (CCITT 106) is interrupted.

Network Init. Data Channel Loopback: Disable (Factory 1) Both (Factory 2) Disable V.54 FT1 Both

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.

Disable – 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.
