Figure 35-7. Transmit-Side ESF Timing
Note 1: TSYNC in frame mode (IOCR1.2 = 0) and double-wide frame sync is not enabled (IOCR1.3 = 0).
Note 2: TSYNC in frame mode (IOCR1.2 = 0) and double-wide frame sync is enabled (IOCR1.3 = 1).
Note 3: TSYNC in multiframe mode (IOCR1.2 = 1).
Note 4: TLINK data (FDL bits) sampled during the F-bit time of odd frame and inserted into the outgoing T1 stream if enabled through TCR1.2.
Note 5: ZBTSI mode is enabled (T1TCR2.1 = 1).
Note 6: TLINK data (Z bits) sampled during the F-bit time of frames 1, 5, 9, 13, 17, and 21 and inserted into the outgoing stream if enabled
Figure 35-8. Transmit-Side Boundary Timing (with Elastic Store Disabled)
Note 1: TSYNC is in the output mode (IOCR1.1 = 1).
Note 2: TSYNC is in the input mode (IOCR1.1 = 0).
Note 3: TCHBLK is programmed to block channel 2.
Note 4: Shown is TLINK/TLCLK in the ESF framing mode.
