unipolar data transmission or B3ZS encoded data transmission.
The system interface consists of one receive clock input and either one receive data
input in unipolar mode or two receive data inputs in dual-rail mode, one for the positive
pulse and one for the negative pulse. In transmit direction the system interface is build
of one transmit clock input and one or two transmit data outputs.

The port handler is the interface between the serial ports and the chip internal protocol
and framing functions. It converts incoming serial data into parallel data for further
internal processing and in the outgoing direction it converts parallel data into a serial bit
stream.
The TE3-CHATT provides one port for operation at DS3 signal speeds. It provides
