NOTES:

1. TLINK timing shown is for 193E framing; in 193E framing, TLINK is sampled as indicated for insertion into

F-bit position of odd frames. When S-bit insertion is enabled in 193S, TLINK is sampled during even frames.

2. If TCR.5=1, TSER is sampled during the F-bit time of CRC frames for insertion into the outgoing data stream

(193E framing only).
