Functional Description
7 - 4
A(n),
B(n)
C(n),
D(n)
Transmit signaling Bits for Channel n. When control bit MSN = 1 and RPSIG = 1 this
nibble is used. For ESF links these 4 bits are transmitted on the associated DS1 channel
(see table 8) in frames 6, 12, 18 and 24. For D4 links bits A are transmit on the associated
Ds1 channel of frame 6 and bits B are transmit on the associated DS1 channel of frame 12.
For D4 links bits C and D are unused.
