Diagnostic (DSU) Configuration Options

Diagnostic Type. This configuration option defines the diagnostic interaction between control and tributary DSUs. All DSUs on the same circuit should be set the same (e.g., if the control is set to NonD, all its tributaries should also be set to NonD).

NonD	Ð Select nondisruptive diagnostics for diagnostic data to be transmitted between the control and the
		tributary DSUs over a separate diagnostic channel.
Disr	Ð Select disruptive diagnostics for diagnostic data to be carried between the control and the tributary DSUs
		over the same (primary) channel as user-transmitted data. User-initiated commands are sent between the
		control and the tributary DSUs disruptively, interrupting data.
Mixed	Ð Select if operating over a multipoint network. This setting supports nondisruptive health and status
		updates, but user-initiated commands are sent between the control and the tributary DSUs disruptively,
		interrupting data.
None	Ð Select none if only local diagnostics are to be allowed; that is, there will be no diagnostic communications
		with remote devices.

In-band Secondary Channel Diagnostic Transport Speed in bps (only displayed when Diag Type is set to NonD and Full Mode is enabled). This configuration option allocates the DSU's port bandwidth when there is no excess bandwidth available for in-band secondary channel transport (used for diagnostic data) operation.

How to Select Bandwidth: Select one of the valid diagnostic speeds from the table below for the DSU's port and the

DDS line's speed, as specified in the Rate(Kbps) configuration option under the DSU option set. (Example: If the DSU's Rate(Kbps) configuration option is set to 9.6 kbps, you can select 100, 400, 800, 1200, or 1600. If you select 400, the resulting DSU port speed will be 9.2 kbps.)

NOTE: When The TDM/Flex is operating at a line rate greater than 19.2 kbps or with a multipoint configuration, 100 bps is not a valid in-band secondary channel transport rate.

If the DSU Rate(Kbps) is equal to Port Speed, or
if the underspeed port speed and sum of the
TDM/Flex ports is equal to the
aggregate speed on the DSU:	Valid diagnostic speeds are:
1.2	100, 400
2.4	100, 400, 800
4.8	100, 400, 800, 1200, 1600
9.6	100, 400, 800, 1200, 1600
19.2	100, 400, 800, 1200, 1600
38.4	100, 400, 800, 1200, 1600
48	100, 400, 800, 1200, 1600
56	100, 400, 800, 1200, 1600
