COMSPHERE DualFlow Data Service Units
TxClkSource: Int for a control DBM, RXC for a tributary DBM
Next Int RXC
Transmit Clock Source . Source of timing for the DBM. Only appears for a V.32 DBM.
Int — Internal clock source. The local DBM provides the timing. This source is used primarily in point-to-point
applications.
RXC — Receive clock source. This source is used primarily in multipoint tributary applications.
Ext — 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
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 — Call is terminated upon loss of carrier.
No — 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
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 — Retraining is initiated automatically.
No — Retraining is not initiated automatically; however, the DBM will respond to a retrain request from a remote
modem.
Single Rate: No
Next Yes No
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 — The DBM operates only at the rate for which it is configured.
No — The DBM will adjust its rate downward to correct a mismatch.
AutoAnswer: Enab
Next Enab Disab
Automatic Answer . Controls whether the DBM answers incoming calls.
Enab — DBM answers incoming calls.
Disab — DBM does not answer incoming calls.
