Channel Status and Control
The TECO3264 implements a highly provisionable architecture that offers per-channel control and status for
numerous functions via the respective data I/O pins. These I/O per-channel control and status pins include ENBP,
NLPFRZ, NLPEN, HRST, HFRZ, CALLB, VSC, TEST[0:7], TONE, TDPR, and VPA. For information on their pin
numbers and functions, please refer to Pin Descriptions, Table 1, on page 10. Figure 7, Control and Status Timing
shows the channel alignment for each control and status signal.
5-4902(F).ar.3
Note: There are 32 bits/frame for each serial stream. TS# represents the time-slot number.
