Figure 46
The Framer Mode G.751 E3 Transmit Input Stream diagrams (Figure 45 and
Figure 46) show the expected format of the inputs TDATI, TFPI/TMFPI, and
TICLK and the output TFPO/TMFPO (and TGAPCLK) when the TEMAP-84 is
configured for the E3 G.751 transmit format. TFPI or TMFPI pulses high for one
TICLK cycle and is aligned to the first bit of the frame alignment signal in the
G.751 E3 input data stream on TDATI. TFPO or TMFPO will pulse high for one
out of every 1536 TICLK cycles, providing upstream equipment with a reference
frame pulse. The alignment of TFPO or TMFPO is arbitrary. There is no set
relationship between TFPO/TMFPO and TFPI/TMFPI. The TGAPCLK output is
available in place of TFPO/TMFPO when the TXGAPEN bit in the DS3 and E3
Master Unchannelized Interface Options register is set to logic 1, as in Figure 46.
TGAPCLK remains high during the overhead bit positions. TDATI is sampled on
the falling edge of TGAPCLK.

The Framer Mode G.751 E3 Receive Output Stream diagrams (Figure 47 and
Figure 48) show the format of the outputs RDATO, RFPO/RMFPO, RSCLK (and
RGAPCLK), and ROVRHD when the TEMAP-84 is configured for the E3 G.751
receive format. RFPO or RMFPO pulses high for one RSCLK cycle and is
