8-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
NOTE: Any change in status will generate an interrupt (if enabled in channel register 0x04h and GIE is set to "1" in the
global register 0x80h). The status registers are reset upon read (RUR).

Arbitrary Pulse Generation
The transmit output pulse is divided into 8 individual segments.
This register is used to program the first segment which corre-
sponds to the overshoot of the pulse amplitude. There are four
segments for the top portion of the pulse and four segments for the
bottom portion of the pulse. Segment number 5 corresponds to
the undershoot of the pulse. The MSB of each segment is the sign
bit.
Bit 6 = 0 = Negative Direction
Bit 6 = 1 = Positive Direction
