Transmit DS3/E3/J2 Overhead Data
(TOH[4:1]). When configured for DS3
operation, TOH[4:1] contains the overhead
bits (C, F, X, P, and M) that may be
inserted in the transmit DS3 stream.
When configured for G.832 E3 operation,
TOH[4:1] contains the overhead bytes
(FA1, FA2, EM mask, TR, MA, NR, and
GC) that may be inserted in the transmit
G.832 E3 stream.
When configured for G.751 E3 operation,
TOH[4:1] contains the overhead bits (RAI,
National Use, Stuff Indication, and Stuff
Opportunity) that may be inserted in the
transmit G.751 E3 stream.
When configured for J2 operation,
TOH[4:1] contains the overhead bits
(TS97, TS98, Framing, X , A, M, E
)
1-5
1-3
that may be inserted in the transmit J2
stream.
If TOHINS[4:1] is a logic 1, the TOH[4:1]
input has precedence over the internal
datalink transmitter, or any other internal
register bit setting. TOH[4:1] is sampled
on the rising edge of TOHCLK[4:1].
