Voice Diagnostics

The software-initiated diagnostics supported on voice cards include the setting of both analog and digital loop backs toward the network and the generation of Quiet Tone and a Digital MilliWatt signal on a port-by-port basis. The operator can also monitor and set the state of the analog leads of any FXS, FXO or E&M port. They can set and monitor the state of the ABCD signaling bits of the digitized voice signal. In cross-connect systems, test functionality also includes the ability to generate test tones (300Hz, 1 kHz and 3 kHz) and transmit those toward the user side or the network side of the system. Refer to Table 26 for detailed information on the diagnostic capabilities of the voice cards.
