System Testing and Diagnostics

14.3.2 Voice Diagnostics

The software-initiated diagnostics supported are voice ports include the setting of both analog
and digital loopbacks 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 or E&M port. They can set and monitor the state of the ABCD
signaling bits of the digitized voice signal. In cross-connect system, 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. The table below shows detailed information
on the diagnostic capabilities of the Voice ports.
