Code Result Description / Recommendation
120 FAIL The SNI circuit pack cannot communicate with the SNI in slot 20 over the circuit
path.
1. Fix any on-board SNI-BD errors against this SNI and the SNI in slot 20.
2. Check the error log via display errors for other SNI circuit packs with
3. Replace this SNI.
4. Replace the SNI in slot 20.
122 FAIL The SNI circuit pack cannot communicate with its neighbor via the circuit path.
1. Fix any on-board errors (SNI-BD, EXP-INTF, and/or DS1C-BD) against the
2. Enter display errors and follow the associated repair procedures for any

4. Replace this SNI.
8-1452 Issue 1 May 2002
Use display errors to find any SNI-BD errors and check display alarms
to see whether the errors have on-board alarms. Then follow the
associated repair procedures for SNI-BD.
SNI-PEER error type 3841. If other SNI circuit packs have SNI-PEER
error type 3841, then replace the SNI in slot 20. Replacing an SNI may be
service interrupting. See
the procedure for replacing an SNI.
NOTE:
If other SNI circuit packs do not have SNI-PEER error type 3841 errors,
the problem could be at either of the peer SNI boards. It is arbitrary as to
which SNI is replaced first. Proceed as follows:
components of this fiber link by using display errors and display alarms
and following the associated repair procedures. (Use the list fiber-link
command to find the fiber link associated with this SNI. The display
fiber-link command can then be used to find the endpoints of the fiber link
and the DS1C circuit pack locations if this fiber link has a DS1 Converter
complex administered.)
FIBER-LK entries for the fiber this SNI is administered on. Check list
fiber-link to determine the administered fiber.
errors and display alarms and follow the associated repair procedures for
any off-board DS1C-BD or DS1-FAC entries for either of the DS1C boards
administered or for the DS1 facilities associated with either of the DS1C
boards administered.
