Figure 20-8. TRANSMIT SIDE D4 TIMING
NOTES:
1) TSYNC in the frame mode (TCR2.3 = 0) and double-wide frame sync is not enabled (TCR2.4 = 0).
2) TSYNC in the frame mode (TCR2.3 = 0) and double-wide frame sync is enabled (TCR2.4 = 1).
3) TSYNC in the multiframe mode (TCR2.3 = 1).
4) TLINK data (Fs - bits) is sampled during the F-bit position of even frames for insertion into the
outgoing T1 stream when enabled via TCR1.2.
5) TLINK and TLCLK are not synchronous with TFSYNC.
