The transmit DS1 data (TD1DAT[28:1]) signals

carry the 28 DS1 streams to be multiplexed.

The TD1DAT[28:1] inputs are sampled on the

rising edges of the corresponding

TD1CLK[28:1] signals.

When the internal M12 multiplexers are

configured for G.747 multiplexing, every fourth

TD1DAT signal (TD1DAT4, 8, 12, 16, 20, 24,

28) is unused and ignored. The remaining

TD1DAT signals should then nominally be

2.048 Mbit/s data streams.

When the internal M12 multiplexers are

bypassed, every fourth TD1DAT signal

(TD1DAT4, 8, 12, 16, 20, 24, 28) may become

a DS2 rate data stream operating at nominally

6.312 Mbit/s. The remaining TD1DAT signals

for the particular M12 multiplexer bypassed are

then unused and ignored.

The internal M12 multiplexers may be

bypassed or configured for G.747 multiplexing

on an individual basis. Thus the configuration

of each of the seven blocks of four TD1DAT

signals is independently programmable.
