DBM Configuration Options
V.13 Signl:Disab
Next Enab Disab Prev
V.13 Signaling. The emulation method used for switched-carrier operation. V.13 signaling applies to the DBM
when the DBM is in Dial Backup mode. If configured for point-to-point nondisruptive diagnostics or
point-to-point rate adaption, this configuration option must be disabled. When backing up a multipoint circuit
configured for nondisruptive or mixed diagnostics or rate adaption, this configuration option must be enabled.
For the V.13 sequence to be generated by a tributary DBM, the following must be set: RTS Cntrl = DTE,
CTS Cntrl = Std, and CTS Lead = Std.
For the V.13 sequence to function at the control DBM, the following must be set: LSD Lead = Std.
The normal RTS/CTS delay is 14 ms at 2.4 kbps and 11 ms at all other speeds when V.13 is enabled. It is
under 2 ms when V.13 is disabled.
NOTE: Although this configuration must be enabled in both the tributary and control DSUs in order to use
V.13 signaling, RTS Cntrl propagation only occurs in the tributary-to-control direction.
Enab — When enabled at both ends, LSD is turned ON at the control while RTS is ON at the tributary,
and is turned Off when RTS is turned Off at the tributary DBM. The V.13 sequence is sent over
the network to tell the control to turn ON LSD.
Disab — V.13 Signaling is turned Off.
Dial Test:Disab
Next Enab Disab Prev
Dial Test. When enabled, the DBM periodically checks for a signal or dial tone. If the test fails, the DSU
reports a Dial Test Failure alarm in its health and status reports. A Dial Test occurs once every 60 minutes
until a failure occurs. Then, the test repeats every minute until the network recovers.
If enabled, the V.32 DBM periodically tests receipt of dial tone, the 4-wire Switched 56 DBM goes off-hook
and checks for receipt of a data mode idle (DMI) signal burst (referred to as winkback detection), and the
2-wire Switched 56 DBM goes off-hook and checks for receipt of a signal to proceed to select from the
DMS-100.
Enab — Enables the Dial Test.
Disab — Disables the Dial Test.
Primary Core:No
Next Yes No Prev
DBM Primary Core. When enabled on a DSU with a DBM installed, the DSU function is disabled and the unit
functions as a V.32 DBM (DBM-V), or Switched 56 DBM (DBM-S or DBM-D). Primary Core can be used in
conjunction with the DTRCallCon configuration option to control dial backup.
Yes — Enables the Primary Core function so the unit operates like a DBM-V, DBM-S, or DBM-D.
When enabled and DTRCallCon is set to Orig, the DBM places a backup call when DTR is
raised and drops the call when DTR goes low.
When DTRCallCon is set to Ansr, the DBM will
not answer a call or will drop a call when DTR is low. Yes is the factory-set (default) setting for
a DBM-V, DBM-S, or DBM-D.
No — Disables the Primary Core function so that the DSU function is active. When disabled, the unit
only answers an incoming call when DTR is raised; it drops the call when DTR goes low.
No is
the factory-set (default) setting for a DSU with an internal DBM installed.
