PKT-BUS (Packet Bus)
Issue 1 June 2005

e. Error Type 2049
S8700 MC
: The Maintenance/Test packet bus port (M/T-PKT) has detected 
a Packet Bus fault and has taken corrective action by swapping to spare leads. This error 
appears only in high/critical-reliability systems (duplicated PNC). The Aux Data value 
indicates the number of faulty leads. If this is the only active error against the packet bus, 
the packet bus is still in service. Due to the disruptive nature of the packet bus Fault 
Isolation and Correction procedures, repairs should be deferred until a time when the least 
interruption in service would result. This should be determined by consultation with the 
customer. However, do not delay repairs for too long, since the switch cannot recover from 
another packet bus failure until the current one is resolved. 
 in Maintenance Procedures (03-300192) contains a sub-section, 
Special Precaution Concerning the TN771D that describes how to ensure that the TN771D 
is providing correct information. A new TN771D may need to be taken to the customer site.
f. Error Type 2305: The Maintenance/Test packet bus port (M/T-PKT) has detected open 
leads on the packet bus. The Aux Data value indicates the number of open leads.
g. Error Type 3329: Packet circuit pack, port, and endpoint maintenance has been disabled 
due to a packet bus failure. The Aux Data value indicates the cause:
Keep in mind that although only packet circuit packs can detect and report packet bus 
problems, such problems can be caused by any circuit pack.
h. Error Type 3585: Packet circuit pack, port, and endpoint maintenance has been disabled 
due to more than one circuit pack reporting in-line errors. If this occurs more than three 
times in 15 minutes a Minor alarm is raised against the packet bus. This happens when 
maintenance is disabled due to errors and is then re-enabled because no more errors are 
reported.
This error may still be present in the error log even though the Packet Circuit Pack Audit test 
(#573) indicates that only one circuit pack is reporting a problem. This happens when more 
than one circuit pack has reported errors in any 1-minute interval since the packet bus fault 
occurred.
i. Error Type 3841: The Maintenance/Test packet bus port (M/T-PKT) for this port network is 
not in service. This alarm does not appear for PNs in standard- or high-reliability systems 
since a TN771D is not required there. The error indicates one or more of the following:
Aux Data
Cause
1
In-line errors from packet circuit packs
2
Uncorrectable packet-bus fault reported
Maintenance/Test packet-bus port (M/T-PKT)
3
Both of the above
100x
Packet-related circuit pack, port, and endpoint maintenance in the 
PN has been disabled due to a packet-bus failure in the PN. The 
last digit has the same meaning as the single digits listed above.
