Abstract
A system is provided for monitoring the operations of a mated pair of switching nodes in a telephone network. A first monitor is provided which is operable to capture data on all of the connection links of a first switching node of the mated pair. A second monitor is provided which is operable to capture data on all of the connection links of a second switching node of the mated pair. The first and second monitors capture selected telephone switching messages on the links of the mated pair. Each monitor compiles either a primary or secondary record of switching messages pertaining to a particular call or transaction being routed by the mated pair of switching nodes. The primary record is maintained by the monitor which detects the first message which initiates a particular call or transaction. Subsequent messages pertaining to that call or transaction that are captured by the other monitor are compiled in a secondary record. At the completion of the call or transaction, selected messages stored in the secondary call record are transferred to the monitor containing the primary record by means of a communications bus connecting the two monitors. The composite record is then analyzed …
