Fiber Link Status
If the fiber link is not OK, there are two possible causes: Either the fiber link has been
installed but disabled (because the license key does not include fiber support), or the
link could not be established even though an optical carrier was detected (due perhaps
to a broken TX fiber, or the link is disabled at the fiber link partner). Note that a
change of status may generate an SNMP trap and/or SMTP email alert.
Telecoms Channel A/B Status
Indicates an alarm condition on a telecoms channel(
Table 7-3
).
Table 7-3 Telecoms channel alarm conditions
Alarm Condition
Meaning
No Signal (Local)
There is no telecoms signal present at the connection to
the ODU at the local end.
No Signal (Remote)
There is an absence of telecoms data across the wireless
link.
No Signal (Local and
Remote)
The above two alarm conditions occur concurrently.
Remote Timing
There is insufficient wireless capacity available to carry
telecoms data. Under these conditions telecoms timing
information is still sent to keep the telecoms clocks
synchronized.
No Signal (Local)
and Remote Timing
Indicates both no local signal and remote timing.
In remote timing mode the ODU will transmit an Alarm Indication Signal (AIS),
consisting of all-ones, from the associated telecoms interface. A change of state may
generate an SNMP trap and/or SMTP email alert.
See
Configuring telecoms circuits
on page

for a description of the Telecoms
Interface.
Telecoms Channel A/B Loopback
The loopback status of telecoms channel A and B. These are intended for installation
testing and should be set to 'None' for normal operation. The wire connections to a
unit can be tested by applying a 'Copper' loopback to the local unit. The wireless
connection to the remote unit can be tested by applying a 'Wireless' loopback to the
remote unit with no loopback on the local unit.
