Paradyne 7112 manual Table A-4. Data Port Options 2, Invert Transmit and Received Data

Configuration Option Tables

Table A-4. Data Port Options (2 of 3)

Invert Transmit and Received Data

Possible Settings: Enable, Disable

Default Setting: Disable

Specifies whether the synchronous data port's transmitted data and received data are logically inverted before being transmitted or received. This configuration option is useful for applications where HDLC data is being transported. Inverting the data ensures that the density requirements for the network interface are met.

Disable ± Indicates the transmitted data and received data for this port are not inverted.

Enable ± Indicates the transmitted data and received data for this port are inverted.

Send All Ones on Data Port Not Ready

Possible Settings: Disable, DTR, RTS, Both

Default Setting: 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 synchronous data port.

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

Disable ± Disables the monitoring of interchange circuits from the DTE connected to the synchronous data 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.

Action on Network Yellow Alarm

Possible Settings: None, Halt

Default Setting: Halt

Specifies the action taken on the synchronous data port when a Yellow Alarm is received on the network interface.

Halt ± Stops the transmission of data on the data 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.

None ± Makes the data port unaffected by Yellow Alarms received on the network interface.
