Echo Canceller Test (#1420)
!
CAUTION:
CAUTION: This test is executed only for MM710 Media Modules that have been
administered on the DS1 Media Module form to provide echo cancellation. The
MM710 must be busied out before this demand test is run.
This test is for the MM710 Media Module. The test originates from a manually
initiated test board long demand test of a MM710 Media Module. The test
instructs firmware to test the echo cancellation circuity. The MM710 firmware
tests echo cancellation on a subset of channels. If any channel fails twice, or if
any two channels fail once, the test fails, and echo cancellation is bypassed on all
channels of the board. Otherwise, the test passes, and echo cancellation is
configured to the administered parameters.
