The XR-2500A system consists of a transmitter, receiver, and signal processing circuitry that is compatible with conventional 1.544 Mb/sec T-1 telephone related signals.  The unit uses linear modulation throughout as well as a signal regeneration scheme that allows excellent transmission of even distorted input T-1 signals.  Input and output transformers assure correct line matching.  Integral LEDs and a loss of signal alarm are also provided to give a continuous indication of the presence of signals and proper operation of the units.  In addition, built in regulators allow operation from unregulated AC or DC sources thereby providing unparalleled versatility in a fiber optic transmission system.
