13.3 E1 Mode
Figure 13-14. Receive Side Timing
NOTES:
1) RSYNC in frame mode (TR.IOCR1.5 = 0).
2) RSYNC in multiframe mode (TR.IOCR1.5 = 1).
3) This diagram assumes the CAS MF begins in the RAF frame.
(With Elastic Store Enabled)
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
2) RSYNC in the output mode (TR.IOCR1.4 = 0).
3) RSYNC in the input mode (TR.IOCR1.4 = 1).
4) RCHBLK is programmed to block channel 24.
