Configuration Option Tables

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

Carrier Control by RTS

Possible Settings: Constant, Switched

Default Setting: Constant

Simulates Constant or Switched Carrier operation.

Constant ± The internal RTS is forced on and the DSU is in a constant Data Mode on the transmit line. The external RTS lead is ignored. The actual signal on the line is either all ones (DMI) or DTE transmitted data.

Switched ± RTS is monitored and CMI codes are transmitted when RTS is off.

CTS Control

Possible Settings: Standard, Follow RTS, Forced On, Circuit Assurance

Default Setting: Standard

Specifies the operation of the Interchange Circuit CT106, Clear to Send (CTS), which is an output from the DSU.

Standard ± CTS follows the internal RTS with a fixed delay, except that CTS will be off when a network interface related alarm is detected or a test is active. The active test may be initiated locally, remotely, or by the network.

Follow RTS ± CTS follows the external RTS lead without delay, regardless of alarms and tests.

Forced On ± CTS is always forced on after the unit is powered up with a successful self-test.

Circuit Assurance ± With circuit assurance, CTS operates the same as the Standard option, except that CTS will also be deasserted when CMI codes are being received.

RLSD Control

Possible Settings: Standard, Forced On

Default Setting: Standard

Specifies the operation of the Interchange Circuit CT109, Received Line Signal Detector (RLSD or CD), which is an output from the DSU.

Standard ± RLSD is asserted when Data Mode is on the receive line. RLSD deasserts when a DDS facility alarm is detected or the DSU is receiving CMI codes.

Forced On ± RLSD is forced on after the unit is powered up with a successful self-test.

DSR Control

Possible Settings: Standard, Forced On, On During Test

Default Setting: Standard

Specifies the operation of the Interchange Circuit CT107, Data Set Ready (DSR), which is an output from the DSU.

Standard ± DSR is always asserted, except when a DDS facility alarm is reported or the DSU is in Test mode.

Forced On ± DSR is forced on after the unit is powered up with a successful self-test.

On During Test ± DSU operates the same as the Standard option, except that DSR remains asserted when the DSU is in Test mode to allow the DTE to send test patterns.
