1. Enter these commands in order: busyout board, reset board, release board.
The board reset is required to reload on-board RAM associated with the TN744’s DSPs.
This takes all 8 Tone Detector ports out of service for a few seconds. Only 4 of the 8
would be out of service due to the alarm. (There are five Tone Detectors on each of the
two DSPs.) Other than the unlikely potential of running out of Tone Detector resources in
the switch, there is no other effect when the board is reset.
2. Test the board with test board location long.
3. If the test still fails, replace the board.
b. Error 257: The CLSFY-PT lost its translation. Testing the CLSFY-PT 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. Error 513: This error indicates the call classifier port is having problems detecting call
classification tones or detecting and generating R2-MFC tones This is usually accompanied
by failures of some incoming or outgoing calls. If this error type is persistently logged, then
replace the call classifier circuit pack containing the defective CLSFY-PT.

Tone Detection Verification Test (#42)
This test checks the operation of the TN744 in touch-tone receiver, call classifier and R2-MFC
modes. It verifies the circuit pack’s ability to detect DTMF, ring back, busy reorder and modem
answer tones and to generate and detect forward and backward MFC tones.
