Diagnostic DBM Configuration Options
Diag Type: Disr
Next NonD Disr None Prev
Diagnostic Type
. Defines the diagnostic interaction between the control and tributary DBMs in Backup mode. It must be
set consistently for all Dualflow DBMs on the same circuit.
NonD — Nondisruptive Diagnostics. An in-band secondary channel transport is derived to carry diagnostics data
between the control and the tributary DBMs.
Disr — Disruptive Diagnostics. The same (primary) channel that carries user-transmitted data between the
control and the tributary DBMs also carries diagnostic data. This mode should be selected for
compatibility with earlier releases that use session-disruptive diagnostics.
None — No diagnostic communications with remote devices; only local diagnostics are allowed.

In-band Secondary Channel Diagnostic Transport Speed (in bps)
. Determines the DBM’s port speed when NonD
(nondisruptive diagnostics) is selected and there is no excess bandwidth available for in-band secondary channel
transport operation. (This configuration option only appears when DiagType = NonD.)
The selection entered here allocates DBM port bandwidth to the in-band secondary channel transport. For example, both
the DBM port speed and the backup line speed are 9.6 kbps, and the Diagnostic Type entered is NonD and the In-band
Secondary Channel Diagnostic Transport Speed entered is 400. The resulting DBM port speed is 9.2 kbps. (Refer to the
following list for valid diagnostic speeds.)
