In the above example, CODEC 1 transmits and receives in the B3 time slot once the U transceiver has
completed the D channel. From the rising edge of FSC1, this is at least 19 DCL clocks later. In

channel. For example, let us say this is 1 DCL clocks long. This defines the programmable delay 1 value
to be 20, (19 + 1), or 0x0014. The DFSC3 signal synchronizes CODECs 3 and 4, and the rising edge of
this frame sync occurs 20 clocks after DFSC2, therefore 40 DCL clocks after FSC1. This defines the value
for programmable delay 3 to be 40, (19 + 1 + 20), or 0x0028.

In this example, ports 0 and 1 are connected to two S/T transceivers. Ports 0 and 1 are programmed in
slave mode. Ports 2 and 3 are not used, and may be disabled.
