NOTE 1: TSERI 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 WILL BE
IGNORED).
NOTE 3: TCHBLK IS FORCED TO 1 IN THE SAME CHANNELS AS TSERI 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 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.)

NOTE 1: TCHBLK IS PROGRAMMED TO BLOCK CHANNEL 24 (IF THE TPCSI BIT IS SET, THEN THE SIGNALING DATA AT TSIG IS
IGNORED DURING CHANNEL 24).
