DBM Port Configuration Options

DTE Port: 232

Next 232 V.35 Prev

DTE Port. Selects which DTE port will be used for DBM data. This configuration option is forced to 232 (EIA-232) unless Primary Core is set to Yes.

232Ð For the EIA-232-D connector, the maximum cable length from the DBM to the router is 34 feet with shielded cable and 68 feet with unshielded cable when operating at 56 kbps.

V.35	Ð Only appears if Primary Core (DBM option set) is set to Yes. For the V.35 connector, all rates are
	available for distances up to 1000 feet.
RTS Cntrl: FrcOn for DiDg, DTE for other configurations
Next	FrcOn	DTE	Prev

Request-to-Send Control. This configuration option determines how the DBM will function with respect to the RTS lead.

FrcOn	Ð	The DBM keeps the internal RTS ON continuously, regardless of whether RTS at the DTE interface is ON
		or Off. FrcOn should be used when the DBM is connected to the console port of a router since the router
		does not support RTS signalling.
DTE	Ð	The DBM responds to RTS from the router.

CTS Cntrl: Std

Next Std =RTS FrcOn Prev

Clear-to-Send Control. Controls the behavior of the CTS lead.

Std	Ð	CTS is normally controlled by the router's RTS lead; however, the CTS lead can be affected by the
		response to abnormal conditions, such as no signal or test mode.
=RTS	Ð	CTS follows RTS.
FrcOn	Ð	CTS remains ON as long as the DSU has power.

AntiStream:Disab

Next Chang Prev

Antistreaming. Antistreaming provides circuit protection against a streaming DTE (a defective DTE that has its RTS lead constantly turned ON) by clamping the RTS lead of the tributary DBM.

If the tributary DTE turns ON RTS longer than the time specified for the Antistreaming configuration option, the tributary DBM turns on its alarm indicator and clamps RTS to Off. Although the tributary DTE is not allowed to send, the DBM can still respond to commands and is capable of being tested or disabled.

Upon detecting that RTS is no longer turned ON, the DBM turns Off its alarm and resets the streaming timer, and allows the DTE to send data once again.

This configuration option only has an effect at a DBM configured with RTS Cntrl set to DTE.

Chang Ð Set timer to Disab, or to any value from 1 to 100 second(s) in increments of 1. When Disab is selected, streaming terminal detection is not provided.

LSD Lead: Std

Next Std FrcOn Prev

Line Signal Detect Lead. Controls behavior of the Line Signal Detect lead.

Std	Ð	LSD lead goes Off in response to a loss of carrier or a switched network failure.
FrcOn	Ð	Keeps LSD on as long as the DBM has power.
