Figure 21-12 TRANSMIT SIDE 2.048 MHz BOUNDARY TIMING (with elastic
store enabled)
Notes:
1. TSER 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
3. TCHBLK is forced to one in the same channels as TSER is ignored (see Note 1)
4. The F-bit position for the T1 frame is sampled and passed through the transmit side elastic store into
TCHBLK
will be ignored).
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)
