DBM Configuration Options
TxClkSource: Int for a control DBM, RXC for a tributary DBM
Next Int RXC Ext Prt1 Prt2 Prt3 Prt4 Prt5 Prt6 DSU Prev
Transmit Clock Source.
1
Source of timing for the 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.
3
This source is used primarily in applications where the connected DTE
must provide the timing, such as a DBM-V application where timing is received from the digital
bridge.
Prt1 — Ports 1—6. The DBM is timed by the Transmit Timing lead on the specified port.
to Prt6 These Prt6 selections are only available when a TDM or MCMP circuit card is installed and
enabled.
DSU — Data Service Unit Clock Source. This source is used when the DSU is connected to a DDS
network and the network provides the timing. DSU should not be selected if the DSU and DBM
operate at different rates.
CarrLossDisc: Yes
Next Yes No Prev
Carrier Loss Disconnect.
1
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 Prev
Automatic Retrain.
1
Controls the automatic start of a retrain sequence by the DBM or DBM-V when received
signal quality becomes unacceptable.
Yes — Retraining is initiated automatically.
No — Retraining is not initiated automatically; however, the DBM will respond to a retrain request
from a remote modem.
1
Does not appear for Switched 56 DBM.
3
In TDM, MCMP or Bridge mode, the DBM’s Transmit Elastic Store setting is ignored; instead, this
configuration option is selected on a per-port basis in the MUX submenu.
