Add Bus Parity Bit: This output bit represents an odd
parity calculation for each data byte that is mapped to the
Add bus in the add timing and Drop bus timing modes.
This lead is forced to a high impedance state when
Receive Line Positive Rail/NRZ Data for Channel n:
When control bit CODE (bit 6 in XC1H) is a 0 for the cor-
responding channel, this lead provides the received NRZ
output for the 44.736 (DS3) or 34.368 Mbit/s (E3) asyn-
chronous line data. When control bit CODE is a 1, a pos-
itive rail output signal is provided. This lead is forced to a
high impedance state when
Receive Negative Rail Data for Channel n: When con-
trol bit CODE (bit 6 in XC1H) is a 0, the corresponding
lead is set to low. When control bit CODE is a 1, a nega-
tive rail output is provided. This lead is forced to a high
impedance state when
