Diagnostic (General) Configuration Options
TribTimOut: 0:10
Next Chang Prev
Tributary Time-out
, specified in minutes and seconds (only displayed when any Diag Type is set to NonD or Mixed,
LinkConfig is set to M-Pt, and Full Mode is enabled). This configuration option specifies the amount of time that the
control DSU or DBM waits before it generates a Tributary Time-out alarm when a tributary does not return a health and
status message when RTS is raised (
only
applies to a MPTC configuration).
Chang — Determine the amount of time it takes for the control DSU to complete its polling cycle, then multiply that
time by the response period entered above (Resp Period). The range that can be entered is from 5
seconds up to 10 minutes.
Link Delay: 0s
Next 0s 1s 2s 5s 10s 20s 50s Prev
Link Delay
, specified in seconds (only displayed when any Diag Type is
set to NonD, LinkConfig is set to Pt-Pt, and Full
Mode is enabled). Used only in point-to-point configurations, this configuration option controls the amount of additional
time that a DSU or DBM will wait for a response from a device downstream (
only
applies to a PTPC configuration).
NOTE: If diagnostic time-outs are occurring during polling, increase the link delay to the next higher setting.
0s to 50s — Set the number of seconds the DSU or DBM will wait for a response from the downstream device. The
range that can be entered is from 0 seconds up to 50 seconds.
Packet Delay: 0s
Next 0s 1s 2s 5s Prev
Packet Delay
, specified in seconds (only displayed when Position is set to Cntrl and Full Mode is enabled). Used only for
a control DSU or DBM, this configuration option controls the amount of time that a DSU or DBM will wait for a packet to
complete from an NMS.
NOTE: Must be used when the DSU’s diagnostic channel operates over packet switch, satellite communications, or
other facilities that provide extended throughput delays.
0s to 5s — Set the amount of time the DSU or DBM will wait for the NMS. The range that can be entered is from
0 seconds up to 5 seconds.
M-PtSymPrt:Enab
Next Enab Disab Prev
Multipoint Symmetrical Port
(only displayed when LinkConfig is set to M-Pt and Full Mode is enabled). Used only in a
multipoint configuration, This configuration option enables rate adaption in the tributary DSU to control direction on a
multipoint circuit. An example of multipoint rate adaption would be when the port speed is
less than
the line speed (
only
applies to MPTC and MPTT configurations).
Use this configuration option when using multipoint rate adaption, or when the transmit data rate must match the
received data rate, or the tributary DSU is configured as a digital-sharing device (DSD).
Enab — Select when multipoint rate adaption is enabled, and when a multipoint network is configured for
nondisruptive diagnostics (
Diag Type
is set to NonD) and a symmetrical port speed is required for proper
DTE operation.
Disab — When disabled, the receive port rate on the control will be the DDS rate, and the transmitter will be the
port rate, minus the diagnostics.
