DBM Configuration Options

TxClkSource: Int for a control DBM, RXC for a tributary DBM

Next Int RXC Ext Prev

Transmit Clock Source. Source of timing for the DBM. Only appears for a V.32 DBM.

Int	Ð Internal clock source. The local DBM provides the timing. This source is used primarily in point-to-point
	applications.
RXC	Ð Receive clock source. This source is used primarily in multipoint tributary applications.
Ext	Ð External clock source. This source is used primarily in applications where the connected DTE must
	provide the timing, such as when a 3616 V.32 DBM with its DBM Primary Core configuration option set to
	Yes and where timing is received from the digital bridge.

CarrLossDisc: Yes

Next Yes No Prev

Carrier Loss Disconnect. Controls whether the V.32 DBM terminates a call when the receive signal carrier is lost or the signal becomes unacceptable.

Yes	Ð	Call is terminated upon loss of carrier.
No	Ð	For factory testing only. Never set Carrier Loss Disconnect to No. Doing so will cause an off-hook line
		condition, resulting in excessive telephone charges.

Auto Retrain:Yes

Next Yes No Prev

Automatic Retrain. Controls the automatic start of a retrain sequence by the DBM when received signal quality becomes unacceptable. Only appears for a V.32 DBM.

Yes	Ð	Retraining is initiated automatically.
No	Ð	Retraining is not initiated automatically; however, the DBM will respond to a retrain request from a remote
		modem.

Single Rate: No

Next Yes No Prev

Single Rate. Determines whether the DBM will adjust its rate to resolve a rate mismatch with a remote DBM. Single Rate must be set to Yes if rate adaption or non-disruptive diagnostics are enabled. Only appears for a V.32 DBM.

If Rate(Kbps) is set to 2.4, the DBM can only talk to a 2.4 kbps modem, regardless of the Single Rate setting. (Will only train at 2.4 kbps.)

Yes	Ð	The DBM operates only at the rate for which it is configured.
No	Ð	The DBM will adjust its rate downward to correct a mismatch.

AutoAnswer: Enab

Next Enab Disab Prev

Automatic Answer. Controls whether the DBM answers incoming calls.

Enab	Ð	DBM answers incoming calls.
Disab	Ð	DBM does not answer incoming calls.
