NOTE 1: TSER DATA IN CHANNELS 1, 5, 9, 13, 17, 21, 25, AND 29 IS IGNORED.
NOTE 2: TCHBLK IS PROGRAMMED TO BLOCK CHANNELS 31 AND 1.
NOTE 3: THE F-BIT POSITION FOR THE T1 FRAME IS SAMPLED AND PASSED THROUGH THE TRANSMIT-SIDE
ELASTIC STORE INTO THE MSB BIT POSITION OF CHANNEL 1. (NORMALLY THE TRANSMIT-SIDE FORMATTER
OVERWRITES THE F-BIT POSITION UNLESS THE FORMATTER IS PROGRAMMED TO PASS THROUGH THE F-BIT
POSITION).
