Alcatel MDR-8000 User Manual page 12

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 you select OFF to disable INSERT CHANNEL (located on the
USI DS1 Facilities screen) for all equipped lines. Disabling the DS1 insert function disables both the lines and
alarm reporting for the lines. After all customer connections are complete, alarm reporting can be restored to
normal. To restore alarm reporting to normal, set INSERT CHANNEL on DS1 Facilities screen to ON.
The term "LINE" is used to describe an input/output signal at DS1/E1 rate (1.544 MB/S 2.043 MB/S). The
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 I/O interface module.
