Table 5-6
Diagnostic General Configuration Options
Position: Cntrl for SyBC, Trib for DiDg and SyBT configurations
Next Cntrl Trib Prev
Network Position
. Determines the DSU’s position in the network, and defines its test and diagnostic capabilities.
Cntrl — Control
Trib — Tributary
RemoteDiag:Enhan
Next V.54 Enhan Prev
Remote Diagnostics
. Determines the type of loopback message generated by a DBM.
V.54 — The V.32 DBM generates a CCITT V.54 loopback sequence. This selection does not appear for a
Switched 56 DBM.
Enhan — The V.32 DBM uses enhanced 3600e protocol and the Switched 56 DBM uses Br56. Both the control and
tributary must be set for Enhan.
Link Delay: 0s
Next 0s 1s 2s 5s 10s 20s 50s Prev
Link Delay
. Controls the additional time (in seconds) that a control DBM will wait for a response from a device one level
downstream. This configuration option does not appear when Diag Type (Diagnostic DBM option set) is set to Disr and
Position is set to Trib (DiDg and SyBT configurations);
this configuration option only appears for a DBM configured as a
control.
NOTE: If diagnostic time-outs are occurring during polling, increase the link delay to the next higher value.
0s to 50s — Sets the time the DBM will wait for a downstream device response.
Packet Delay: 0s
Next 0s 1s 2s 5s Prev
Packet Delay
. Controls the time (in seconds) that a control DBM will wait for a packet to complete from an NMS.
This
configuration option only appears for a DBM configured as a control
.
NOTE: Must be used when the DualFlow DSU’s diagnostic channel operates over packet switch, satellite
communications, or other facilities that provide extended throughput delays.
0s to 5s — Sets the time the DBM will wait for the NMS.
