NOTE 1: TCHBLK IS PROGRAMMED TO BLOCK CHANNEL 24 (IF THE TPCSI BIT IS SET, THEN THE SIGNALING DATA AT TSIG WILL BE
IGNORED DURING CHANNEL 24).
NOTE 1: TSER DATA IN CHANNELS 1, 5, 9, 13, 17, 21, 25, AND 29 IS IGNORED.
NOTE 2: TCHBLK IS PROGRAMMED TO BLOCK CHANNEL 31 (IF THE TPCSI BIT IS SET, THEN THE SIGNALING DATA AT TSIG IS IGNORED).
NOTE 3: TCHBLK IS FORCED TO 1 IN THE SAME CHANNELS WHERE TSER IS IGNORED (SEE NOTE 1).
NOTE 4: THE F-BIT POSITION FOR THE T1 FRAME IS SAMPLED AND PASSED THROUGH THE TRANSMIT SIDE ELASTIC STORE (NORMALLY
THE TRANSMIT SIDE FORMATTER OVERWRITES THE F-BIT POSITION UNLESS THE FORMATTER IS PROGRAMMED TO PASS-THROUGH THE
F-BIT POSITION).
NOTE 5: TCHCLK DOES NOT TRANSITION HIGH IN THE CHANNEL IN WHICH THE DATA AT TSER IS IGNORED (SEE NOTE 1).
