LSD Control: Stndrd_RS232

BridgeRetrain

Line Signal Detect Control. LSD is a signal indicating that the carrier signal is being received from the remote modem. It is normally turned Off to the DTE when the power level of the received carrier signal drops below the carrier detect threshold.

Standard RS232 – LSD is ON when the modem detects the remote modem’s carrier signal. LSD turns Off when the carrier signal strength drops below carrier detect threshold.

Forced On – Forces LSD to be ON at all times.

Wink When Disconnect – LSD is normally forced ON, but can be turned Off for 1 to 2 seconds upon a disconnect. This is used for UNIX DTEs.

Follows DTR – The state of LSD follows the state of DTR. When DTR turns ON, LSD turns ON. When DTR turns Off, LSD turns Off.

Simulated Control Carrier – LSD follows the state of RTS of the remote DTE via the V.13 simulated control carrier signaling. This is required for hosts that cannot support full-duplex operation.

NOTE: If LSD Control is set for simulated control carrier, then the RTS Action configuration option on the remote modem must be set for Simulated Control Carrier.

=DTR/Disconnect Off – The state of LSD follows the state of DTR except when disconnecting once a connection is established. In this instance, DTR remains ON and LSD turns Off. DTR must then toggle Off and then ON again for LSD to turn ON. This setting is required for AT&T DATAKITr dial-out applications.

BridgeRetrain – LSD behaves as if it were set for Standard RS232, except that it is turned off when a retrain condition lasts longer than10 seconds, and turned on again when no retrain condition is detected for a period of 10 seconds.

NOTE: If LSD Control is set for =DTR/DiscOff, then the DTR Action configuration option must be set for Stndrd_RS232.

For Async Dial, Sync Dial, and Sync Leased, Stndrd_RS232 is the factory default.

For UNIX Dial, WinkWhenDisc is the factory default.

AT command for Forced On is &C0.

AT command for Standard RS232 is &C1.

AT command for Wink When Disconnect is &C2.

AT command for Follows DTR is &C3.

AT command for Simulated Control Carrier is &C4.

AT command for =DTR/Disconnect Off is &C5.

AT command for BridgeRetrain is &C6.

TX Clock Source: Internal

Nxt Internal External RXC_Loop

Transmit Clock Source. Determines the source of timing for synchronous data transmitted from the DTE.

Internal – The transmit data’s clock source is derived from the modem’s internal clock and output on Pin 15 (TXC) of the EIA-232-D interface.

External – The transmit data’s clock source is provided by the DTE on Pin 24 (EXT) on the EIA-232-D interface.

Receive Clock Loop – The modem’s transmit clock is derived from its received signal and is output on Pin 15 (TXC) of the EIA-232-D interface.

NOTE: This configuration option only appears if Async/Sync Mode is configured for Sync.

The factory default is Internal.

AT command for Internal is &X0.

AT command for External is &X1.

AT command for RXC Loop is &X2.
