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/π). |
