NOTES:
1. TSYNC in the frame mode (TCR1.1=0).
2. TSYNC in the multiframe mode (TCR1.1=1).
3. TLINK is programmed to source only the Sa4 bit.
4. This diagram assumes both the CAS MF and the CRC4 begin with the align frame.

NOTES:
1. TSYNC is in the input mode (TCR1.0=0).
2. TSYNC is in the output mode (TCR1.0=1).
3. TCHBLK is programmed to block Channel 2.
4. TLINK is programmed to source the Sa4 bits.
5. The signaling data at TSIG during Channel 1 is normally overwritten in the transmit formatter with the CAS
multiframe alignment nibble (0000).
6. Shown is a non–align frame boundary.
