12.2 CCU Troubleshooting

CCU troubleshooting can be broken down into several areas, based on the working history of

the CCU, the nature of the reported problem, and the extent of the reported problem. For the

purpose of this troubleshooting section, it is assumed that the CCU has been installed

according to the guidelines provided by WaveRider and EUMs have been successfully

deployed and operated. Subsequent problems can then be divided into the following

categories:

• Unable to add new EUMs

• New EUMs cannot get service

• Adding new EUMs causes degraded performance to existing EUMs

• Complaints of degraded performance

• Customer complaints of slow throughput

• Service outages

• All customers have no service

• Some customers have no service

• Key Statistics (refer to Monitoring the Network on page 127) indicate an increase in

retransmitted and/or lost packets

The possible causes for these problems can be identified as follows:

• Configuration error at CCU

• System congestion

• Impacts EUMs depending on their assigned GOS level

• Presence of an interferer

• Impacting the CCU

• Impacting all or most EUMs in the sector

• Hardware failure of the CCU system (CCU, power, antenna, etc.)

• Impacts all EUMs in the sector

Regardless of the extent of the reported problem, there exist remote and local tests that can

be used to isolate the cause.

Since there are so many possible entry levels to a troubleshooting procedure, the following

troubleshooting guides are intended to provide suggested tests that can be carried out as part

of the troubleshooting process. Some tests may not be required in all scenarios and good

judgement should be used when carrying out the tests.

The remote CCU tests outlined in Table34onpage146are generally useful as a starting point

for all CCU troubleshooting. These tests should be carried out prior to performing the local

tests outlined in Table35onpage147, keeping in mind the remote tests can be carried out

locally using the serial port to access the CLI command set.
