Flowchart description and supplement
An uppercase letter in bold (for example, A, B, C, etc.) indicates that there is supplemental information
with details about the relevant process that could not fit into the appropriate box or diamond.
NOTE:
Due to space restrictions, individual error codes and alarms are not detailed on the
flowchart. The maintenance object descriptions in Maintenance Alarms Reference (555-
245-102), discuss which errors and alarms could cause or be indicative of Packet Bus
problems. In general, unless an error, alarm, or test refers explicitly to the TDM Bus, the
error, alarm, or test should be considered a possible cause of Packet Bus problems.
