CLSFY-PT (Call Classifier Port)
Issue 4 May 2002 10-413 555-233-123
Notes:
a. There are two possible alarm levels for this error type: major alarm and
minor alarm. A major alarm is raised if the total number of call classifier
ports currently in-service is less than or equal to 1/2 of the administered
threshold number. Otherwise, a minor alarm is raised. In either case, run
the short test sequence against the port and follow the error code
procedures for the individual tests.
The threshold number of call classifier ports for service is administered
using the change system-parameters maintenance command. For
details, refer to Chapter 5, “Routine Maintenance Procedures”.
b. The call classifier port lost its translation. Testing the call classifier port is
sufficient to reload its translation. If testing the call classifier port does not
clear the error, then the call classifier circuit pack containing the defective
call classifier port should be replaced.
c. This error indicates the call classifier port is having problems detecting
system tones (DTMF, etc.) or detecting and generating necessary R2-MFC
tones. This error should accompany some percentage of failed calls. If this
error type is persistently logged, then the call classifier circuit pack
containing the defective call classifier port should be replaced.
System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the following tables when
inspecting errors in the system. By clearing error codes associated with the Tone
Detection Verification Test, for example, you may also clear errors generated from
other tests in the testing sequence.
Tone Detection Verification Test (#42)
This test checks out each port in both the touch-tone receiver mode and in the
R2-MFC tone detection/generation mode. During the first half of the test, the
touch-tone receiver mode is tested. In the second half of the test, each port is put
into the R2-MFC mode. During this portion of the test, each port’s ability to
accurately detect and generate all forward and backward MFC tones is verified.
