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.
