The PTP radio has changed wireless channel.
This has been caused by either
i) mandatory radar avoidance,
   a DFS impulsive interference event will also be
   detected,
or
ii) Dynamic Spectrum Optimization, (DSO)
    DSO improves link performance by selecting the
    most appropriate transmit and receive channels
    with the lowest level of interference.

Indicates if the unit is being installed. NB: a value 
other than 'disarmed' on startup, or a change of state 
during operation may generate an SNMP trap and/or SMTP 
email alert

The unit is out of calibration

The master and slave units have incompatible region 
codes. NB: Both units must have compatible licence keys

Spectrum Management was unable to locate a suitable 
wireless channel to operate on

The SNMP ifAdminStatus of the wireless interface has 
disabled wireless traffic

The SNMP ifAdminStatus of the Ethernet interface has 
disabled Ethernet traffic

The detection of Ethernet fragments (runt packets) when 
the link is in full duplex is an indication of an 
auto-negotiation or forced configuration mismatch

DFS impulsive interference detected event

A non-zero value indicates that the master and slave 
ends of a link are different hardware products, or have 
different software versions. NB: It is very unusual to 
detect this, because incompatible units will normally 
fail to establish a wireless link. However, some 
combinations may establish a partial wireless link and 
detect this situation. NB: A non-zero value may generate 
an SNMP trap and/or SMTP email alert

If SNTP Sync fails then check the server settings in the 
Remote Management page, or disable SNTP. NB: a change of 
state may generate an SNMP trap and/or SMTP email alert

Not Synchronized indicates failure of the external 
timing system for a period greater than the holdover 
timer. TDD frame timing will have drifted, and this link 
may cause interference with other links in a synchronized 
network. Timing System Failure is an early warning, 
indicating that 80% of the holdover period has expired.

The remote node of this link has been configured with a 
different link mode optimization

The local and remote units have different licensed 
capacity and/or the full capacity trial has been 
activated at only one unit. The wireless link is 
operating at the capacity of the lowest capacity unit

Current status of the Ethernet link. NB: a change of 
state may generate an SNMP trap and/or SMTP email alert

The syslog service has been enabled or disabled

The syslog local log is nearly full (90%)

The syslog local log has wrapped

Enable or disable the syslog client

Current status of telecoms channel. NB: a change of 
state may generate an SNMP trap and/or SMTP email alert

The loopback status of 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. When 
applying a wireless loopback, please ensure that the 
other end of the link has a loopback setting of 'None'. 
NB: a change of state may generate an SNMP trap and/or 
SMTP email alert

The region code prohibits the wireless unit from 
operating outside the regulated limits. An invalid region 
code indicates a corrupted licence key. NB: a change of 
state may generate an SNMP trap and/or SMTP email alert

A non-zero value indicates that signalling was received 
with the wrong MAC address or a mismatched link name. NB: 
It is very unusual to detect this, because units with 
mis-configured Target MAC Address will normally fail to 
establish a wireless link. However, rare circumstances 
may establish a partial wireless link and detect this 
situation. NB: A non-zero value on start-up, or a change 
of value during operation, may generate an SNMP trap 
and/or SMTP email alert
