Far-End Internal Loopback Test (#797)
This test starts at the specified DS1 converter circuit pack location, traverses over the specified
facility, and loops at the internal facility interface on the other DS1 converter circuit pack in the
DS1 converter complex. See Figure 109: Far-End Internal Loopback Test Configuration.
The test sends digital data through every DS1 chel on this facility. For TN574 DS1 Converter
facilities, test patterns are sent through every DS1 chel. For TN1654 DS1 Converter facilities,
test patterns are sent through one DS1 chel.
If there is only one DS1 facility available, the system will not allow that last facility to be busied
out. In that case, the DS1 converter circuit pack must be busied out before executing this test.
For a standard-, duplex-, or high-reliability system (no PNC duplication), if there is only one DS1
facility available, then this test can only be executed at the endpoint that is closer to the server
relative to the neighbor DS1 converter circuit pack because of its impact on the system control
links. For TN574 DS1 converter boards, the completion of the test will be delayed in this
configuration to wait for the recovery of the system control links. For a critical-reliability system
(PNC duplication) or for a system with multiple DS1 facilities, the test can be executed on any
DS1 converter circuit pack.
If the test passes on a TN1654 DS1 facility, the round trip delay time appears in milliseconds in
the Error Code field. The round trip delay time is the length of time in milliseconds it takes for
the firmware to receive the test pattern after it has been sent.
This test runs on the DS1-FAC (DS1 Facility) maintenance object.
