NOTES:
1) TSERI data in channels 1, 5, 9, 13, 17, 21, 25, and 29 is ignored.
2) TCHBLK is programmed to block channel 31 (if the TPCSI bit is set, then the signaling data at TSIG will be
3) TCHBLK is forced to one in the same channels as TSERI is ignored (Note 1).
4) The F-bit position for the T1 frame is sampled and passed through the transmit side elastic store into the MSB
ignored during channel 24).
