Maintenance Demand Tests
The DS1 Facilities Connectivity Test checks the correct connectivity of the DS1 facilities at
opposite ends of the DS1 converter complex.
For TN574 DS1 Converter circuit packs, this test sends digital data through each time slot of
every DS1 facility chel. Two different test patterns are used: hexadecimal values 55 and AA.
For TN1654 DS1 Converter circuit packs, this test provides error codes that point to the exact
fault. The TN1654 test specifically identifies the two DS1 facilities that are cross-connected at
the near and far ends of the DS1 converter complex. In addition, a fault code will indicate the
condition of not being able to loop-up the far end, as required to run the test, due to the packet
DS1 facility being down.
The TN1654 connectivity test sends digital data through only one time slot. Instead of looping
back the facility to itself, the TN1654 version of the test loops-up the other three facilities. If the
test pattern comes back, the firmware fails the test due to an incorrect connection between DS1
facilities. It should be noted that this test will pass and give no indication of problems if the
non-packet facilities are down.
For a standard-, duplex-, or high-reliability system (no PNC duplication), 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. In addition, 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), the test
can be executed on any DS1 converter circuit pack.
This test runs on DS1C-BD (DS1 Converter Circuit Pack).

Description / Recommendation
ABORT Timed out while waiting for a response from the circuit pack.
Could not allocate the necessary system resources to run this test.
The downlink message necessary to run this test could not be sent.
The timer could not be set before sending the downlink message.
1. Retry the command at 1-minute intervals up to 3 times.
2316 ABORT Fiber link is not administered.
1. Enter addfiber-link to administer the DS1 converter fiber link.
2321 ABORT DS1 converter circuit pack is not busied out.
1. Enter busyout board to busyout the DS1 converter circuit pack.
2332 ABORT With this system configuration (unduplicated PNC), the test cot be run at
the far end when there is only one DS1-FAC available. The link would be
lost, and no test results would be seen at the server. Run the test at the
other end of the DS1C complex.
