Abstract:

A system and method for capturing signaling units at international gateways in a communications network is disclosed. The signaling units are processed to determine the source and destination networks for the associated calls. The country code, nature of address field, destination point code and origination point code is used to process each message.

Abstract:

A system is provided for monitoring the operation 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 in the network. A second monitor is provided which is operable to capture data on all of the connection links of a second switching node. The first and second monitors capture selected telephone switching messages on the links of the nodes. Each monitor compiles either a primary or secondary record of switching messages pertaining to a particular call or transaction being routed by 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. During the call or 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.
