Notes:
1. All specifications are for a single channel of Si3226/7 using Si3208/9 linefeed IC and based on measurements with all
channels in the same operating state.
2. ILOOP is the dc current in the subscriber loop during the off-hook state.
3. IAVE is the average of the full-wave rectified current in the subscriber loop during ringing (IAVE = IPEAK x 2/Ï€).
