7.2.2 System Alarms
The following system alarms are defined:
Ethernet Link Status
Current status of the Ethernet link. If there are any problems with the Ethernet interface, this
alarm will be asserted. This alarm will most likely be seen if the unit has no Ethernet cable
plugged into its Ethernet socket. Note that a change of state may generate an SNMP trap
and/or SMTP email alert.
Telecoms Channel Status
Indicates an alarm condition on the telecoms channel. Alarm conditions are listed in Table 9.
Table 9 – Tel
ecoms Channel Status 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 telecoms interface. A change of state may generate an SNMP trap and/or
SMTP email alert.
See section 7.7.3.1 “Telecoms Interface” for a description of the Telecoms Interface.
Telecoms Interfa
ce Loopback
The loopback status of the telecoms channel. This is 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.
A change of state may generate an SNMP trap and/or SMTP email alert. The loopback can
be disabled from the telecoms configuration sub menu (see Section 7.5.5 “Telecoms
Config
uration”).
See section 7.7.3.1 “Telecoms Interface” for a description of the Telecoms Interface.
Region Cod
e
The region code prohibits the wireless unit from operating outside the regulated limits. An
invalid region code indicates a corrupted license key. Note that a change of state may
generate an SNMP trap and/or SMTP email alert.
