The TN744 Call Classifier is a service circuit pack that provides specialized tone detection 
capabilities to support the Outbound Call Management (OCM) and Inbound Call Management 
(ICM) features.  The TN744 supports both A-law and Mu-law companding.
The TN744 has eight ports (CLSFY-PTs), each capable of supporting call classification, 
touch-tone reception and MFC-tone generation and detection.  The CLSFY-PT MO implements 
a set of tests designed to ensure proper operation of the Call Classifier.

Notes:

a. 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.  For major or minor alarm,  run 
the short test sequence on the alarmed port and follow the error code procedures for the 
individual tests.

The in-service threshold number for alarming call classifier ports is administered using the 
change system-parameters maintenance.
