8-CHANNEL E1 SHORT-HAUL LINE INTERFACE UNIT
FUNCTIONAL DESCRIPTION
REV. P1.0.0
The XRT83VSH28 is a fully integrated 8-channel short-haul line interface unit (LIU) that operates from a 1.8V
and a 3.3V power supply. The LIU features are programmed through a standard microprocessor interface or
controlled through Hardware mode. EXAR’s LIU has patented high impedance circuits that allow the
transmitter outputs and receiver inputs to be high impedance when experiencing a power failure or when the
LIU is powered off. Key design features within the LIU optimize 1:1 or 1+1 redundancy and non-intrusive
monitoring applications to ensure reliability without using relays. Additional features include RLOS, a 16-bit
LCV counter for each channel, AIS, QRSS generation/detection, Network Loop Code generation/detection,
TAOS, DMO, and diagnostic loopback modes.
1.0
HARDWARE MODE VS HOST MODE
The LIU supports a parallel or serial microprocessor interface (Host mode) for programming the internal
features, or a Hardware mode that can be used to configure the device.
1.1
Feature Differences in Hardware Mode
Some features within the Hardware mode are not supported on a per channel basis. The differences between
Hardware mode and Host mode are descibed below in
