NO-OP Tests
The maintenance strategy for EMBEDDED AUDIX emulates the one for DIG-LINE. The tests
listed below apply only to DIG-LINE and not to EMBEDDED AUDIX. These tests always return
PASS.
● Electronic Power Feed test (#11)
● Station Lamp Updates test (#16)
● Station (Digital) Audits test (#17)
● Digital Terminal Remote Looparound test (#1201)
NPE Crosstalk Test (#9)
NPE Crosstalk Test (#9) verifies that this port’s NPE channel talks on the selected time slot and
that it never crosses over to time slots reserved for other connections. If the NPE is not working
correctly, one-way and noisy connections may be observed. NPE Crosstalk Test (#9) is part of a
port’s long test sequence, and it executes in about 20 to 30 seconds.
Crosstalk testing is performed on both the primary (for voice) and the secondary (for data)
information channel associated with each EMBEDDED AUDIX port. If this test fails on either
channel, the voice port is taken out-of-service.
