technician
busy-out board
command before running the Internal Looparound
Test. When the Internal Looparound Test is initiated, maintenance software sends
appropriate messages to the DS1 Interface circuit pack to start the test. The test
uses the Tone Generator and Tone Detector to exercise a bit pattern consistency
test for all ports. If the transmitted and received bit patterns on a trunk are
different, the test fails.
When the test is complete, the maintenance software sends a stop loop around
message to the DS1 Interface circuit pack to put the circuit pack back into the
normal operation mode. All trunks of the DS1 Interface circuit pack are restored
to the in-service state after the
release board
command is entered
