COT Ring Detection

The COT channel unit recognizes an ac signal

between tip and ring leads with an amplitude

from 65 Vrms to 104 Vrms and frequency

between 16 Hz and 50 Hz as a ringing signal.

This signal may be superimposed on a dc

component of -36.0 Vdc to -56.5 Vdc applied to

the ring lead with respect to the tip lead. The

tip lead may or may not be referenced to

ground. The source impedance of the ringing

signal must be less than 500 ohms.
