Diagnostics and Troubleshooting
General Information
This section covers information and operation of the system that you will
need to refer to when troubleshooting the CTPhone 1900 system.
CTPhone Controller LEDs
Boot Sequence
After power is applied to the CTPhone Controller, all LEDs except for
POWER, RLOS1, and RLOS2 go through the changes described below.
Note The POWER LED is always lit when the CTPhone Controller has
power. The RLOS LEDs flicker during boot tests and are lit when there is a
problem with base station connections.
1 LEDs are lit for one second to show that they all work.
2 LEDs are turned off for a brief moment.
3 LEDs are lit.
4 Each LED is turned off as the test(s) that corresponds to that LED
passes.
If an LED remains lit after the boot tests complete, one or more hard-
ware integrity tests have failed. Call processing software will usually
start even if some of the tests fail, although some failures prevent call
processing software from starting.
The MASTER LED is not turned off during boot up because it does not
correspond to a boot test.
Table 5-B on page 5-10 explains the meaning of various states of the
LEDs on the CTPhone Controller during boot up and normal operation.
