If installation at both ends of a hop are complete except for connecting to customer inputs/outputs and it is desirable to have an
alarm-free system, alarm reporting on the incomplete connections can be disabled temporarily through provisioning. You can
communicate over the hop even if you do not have the radio connected to customer DS1 inputs; however, you will alarm unless

•
ALWAYS SELECT ON WHEN LOCAL DATA IS INSERTED.
•
ALWAYS SELECT OFF AT EITHER A TERMINAL OR A
NON-PROTECTED REPEATER WHEN LOCAL DATA IS NOT
INSERTED.
•
ONLY SELECT NM ON UNUSED CHANNELS AT PROTECTED
REPEATERS.
UNUSED CHANNELS ARE DEFINED AS CHANNELS THAT HAVE
NEITHER LOCALLY INSERTED DATA NOR PASS-THRU DATA ACROSS
THE REPEATER CABLE. SELECT OFF IF LOCAL DATA IS NOT
INSERTED AND THE CHANNEL HAS PASS-THRU DATA ACROSS THE
REPEATER CABLE (NOTE: SELECTING NM IN THIS CASE WILL
CAUSE THE DATA FROM THE REPEATER TO BE OVERWRITTEN
WITH AN AIS SIGNAL PRIOR TO TRANSMISSION).
USING THE REPEATER CABLE TO PASS DS1 DATA ON CHANNELS
5-16 IS NOT RECOMMENDED ON MDR-8000 RADIOS. PASSING THE
DATA THROUGH ON THESE CHANNELS WILL PREVENT
INDEPENDENT SWITCHING BETWEEN THE DS1 I/O AND THE RADIO
TRANSMITTERS. THE DATA SHOULD BE DROPPED AND
REINSERTED AT EACH REPEATER NODE.

term "CHANNEL" is used to describe a multiplexed
signal, at a higher rate than DS1/E1.
channel is output of multiplexer circuit. The dropped
channel is input to demultiplexer circuit. The
multiplexer and demultiplexer circuits are located on
