Notes:
When problems persist, use reset board to reset the DS1 converter circuit pack. This may 
temporarily resolve the error condition and restore service until further assistance is provided.
a. Error Type 0: Run the short test sequence first. If every test passes, run the long test 
sequence. Refer to each test’s description, and follow its recommended procedures.
b.  Error Type 1: A major failure occurred on the DS1 interface hardware on the DS1 
converter circuit pack associated with this DS1 facility. Replace the DS1 converter circuit 
pack.
c. Error Type 18 indicates that the DS1 facility has been busied out via the busyout 
ds1-facility command. To resolve this error, release the DS1 facility via release 
ds1-facility
.
d. Error Type 257: A minor failure occurred on the DS1 interface hardware on the DS1 
converter circuit pack associated with this DS1 facility. Replace the DS1 converter circuit 
pack.
e. Error Type 513: DS1 converter circuit packs in this DS1 converter complex do not match in 
their framing formats or line coding formats.
Aux Data 1 indicates that the framing formats (ESF or D4) do not match. For TN574 DS1 
converter boards, the framing mode is administered on the fiber-link screen. The TN1654 
DS1 converter has option switches located on the component side of the circuit pack. If T1 
operation is selected via the first switch, four additional switches are used to select the 
framing mode for each facility. The Framing Mode field on the fiber-link screen is 
display-only for the TN1654 boards. It displays what the switch is set to for the DS1 facility. 
It cannot be administered.
Aux Data 2 indicates that the line coding formats do not match. Line Coding is an 
administrable value on the fiber-link screen. The line coding options are ami-zcs or b8zs for 
TN574 boards and TN1654 boards in T1 mode. For TN1654 boards in E1 mode, the line 
coding options are ami-basic or hdb3.
This error should clear in 15 minutes.
1. Verify that DS1 facility and the network is using the same line coding (ami-zcs, b8zs, 
ami-basic, hdb3) and framing mode (ESF, D4). Use list fiber-link and display 
fiber-link
 to check the values for this DS1 facility. Contact T1 Network Service to 
check the modes used by the network.
If the framing mode format differs on boards in a TN1654 DS1 converter complex, the 
DS1 converter board that has its option switch set incorrectly will have to be physically 
removed from the system in order to set the facility framing mode switch properly.
2. If the problem persists, reset both DS1 converter circuit packs via the reset board.
3. If the problem still persists, replace this DS1 converter circuit pack.
4. If the problem still persists, replace the DS1 converter circuit pack at the other end of the 
DS1 converter complex.
