Digital Logic
The logic provides alarms, optional B8ZS coding, blue-
signal insertion (AIS) circuits, and maintenance loop-
backs. It accepts dual-rail or single-rail data patterns.
Single-Rail/Dual-Rail Option
To implement the rail-select feature, the dual pin (pin 23)
is cleared for single-rail mode and set for dual-rail mode.
When single-rail mode is selected, pin 8 (TDATA/
TPDATA) accepts transmit data and pin 6 (
RDATA
/
RPDATA) outputs inverted receive data. When dual-rail
mode is selected, pin 8 (TDATA/TPDATA) accepts the
positive rail transmit data, and pin 3 (BZSC/TNDATA) is
reconfigured to accept negative rail transmit data. Pin 6
(
RDATA
/RPDATA) outputs positive rail receive data, and
pin 4 (BPV/RNDATA) is reconfigured to output negative
rail receive data. In dual-rail mode, the B8ZS and bipo-
lar violation functions are disabled.
For single-rail operation, TDATA is active-high and
RDATA
is active-low. For dual-rail operation, TPDATA,
TNDATA, RPDATA, and RNDATA are all active-high.
This interface scheme is consistent with the dual-rail
interfaces of other Lucent Line Interface products.
