RECEIVE SIDE 1.544 MHz BOUNDARY TIMING
(WITH ELASTIC STORE ENABLED) Figure 11-3
NOTES:
1. Data from the E1 channels 1, 5, 9, 13, 17, 21, 25, and 29 is dropped (channel 2 from the E1 link is
mapped to channel 1 of the T1 link, etc.) and the F-bit position is added (forced to one).
2. RSYNC is in the output mode (RCR1.5=0).
3. RSYNC is in the input mode (RCR1.5=1).
4. RCHBLK is programmed to block channel 24.
