2000 ABRT Response to the test request was not received within the allowable time
period.
1. Retry the command at 1-minute intervals up to 5 times.
2012 ABRT Internal system error.
2103 ABRT The system could not make the conference connection for the test.
1. Retry the command at 1-minute intervals up to 5 times.
7 FAIL The conference circuit test failed. The conference circuit test is
performed only if the hybrid test passes. The conference circuit test
verifies that the network processing element (NPE) can correctly
conference several test tones together. The test is executed in two parts.
The first half of the test verifies the operation of the NPE's first three
conference channels, while the second half verifies the NPE's remaining
four conference channels. The test puts the NPE in loop around mode
and instructs it to talk on a specified time slot while listening to a 1004-Hz
tone, using the conference channels. A GPTD then measures the signal
and noise levels of the conferenced output and reports whether or not
these are within an acceptable range. The failure may be due to
off-board circumstances, the most common of which is an off-hook
occurring during the test. It is possible that the port may still be functional
from a user's point of view. Also, check the error logs against the
GPTD-BD, the TONE-BD, and the TONE-PT.
1. This error can be caused by a disconnected terminal. First, ensure
that the terminal is connected and the wiring is OK.
2. Then, enter display port and status station to determine
whether the station is idle. If so, enter test port for this port.
3. If test continues to fail, enter busyout port and release port,
and retest the port.
