Processor Interface Loop Around Test (#182)
This test is destructive.
The Processor Interface Loop Around Test is an on-board Loop Around Test. The
test requires that the system technician issue a busyout link lnk-no command
before this test is run. This means that the DCS, AUDIX, or ISDN link, for
example, is torn down. It does not access the TDM Bus at all. When the circuit
pack is put into local loop around mode, frames are looped internally on the
circuit pack. If the test fails, the Processor Interface circuit pack reports the
failure. It is a good check of most of the working hardware on the Processor
Interface circuit pack.
1. D = Destructive; ND = Nondestructive
2. If the PI-LINK under test is BX.25 and if there is an MPDM or an MTDM as part of the link, then
the PI-LINK test sequence is expanded to include the tests on the data module. These tests are
run via the PDMODULE or TDMODULE maintenance object. Refer to the PDMODULE
TDMODULE (Data Module) Maintenance documentation for descriptions and details of these
tests.
