Figure 35-17. G.802 Timing, E1 Mode Only
Note 1: RCHBLK or TCHBLK programmed to pulse high during time slots 1 through 15, 17 through 25, and bit 1 of time slot 26.
Figure 35-18. Transmit-Side Timing
Note 1: TSYNC in frame mode (IOCR1.2 = 0).
Note 2: TSYNC in multiframe mode (IOCR1.2 = 1).
Note 3: TLINK is programmed to source just the Sa4 bit.
Note 4: This diagram assumes both the CAS MF and the CRC4 MF begin with the TAF frame.
Note 5: TLINK and TLCLK are not synchronous with TSSYNC.
