Abstract

A switch interface unit, a monitor unit, and a control system interface unit are connected as external units to a highway to which a subscriber information processing unit is also connected so that a monitoring process, that is, a special study process, can be simplified and a cost charged for the subscriber information processing unit can be prevented from increasing greatly. Furthermore, in an accounting process, accounting parameters are accumulated in an accounting information accumulating unit for variations on compressed source addresses, not on source addresses. As a result, the accounting information accumulating unit, etc. can be realized with normal circuit elements only.

Claims17

Dependent claims

A subscriber information processing system in a connectionless data service, comprising:

a connectionless data processing station connected to a highway;
switch interface means, provided to said connectionless data processing station and disconnectably-connected thereto as an external unit via said highway;
a subscriber information processing unit for processing subscriber information connected to said highway, said switch interface means being controlled to enter cells corresponding to predetermined source addresses or predetermined destination addresses from among cells entered by the highway;
monitor means, provided to the connectionless data processing station and being coupled to said switch interface means, for monitoring predetermined subscriber information in the cells entered by said switch interface means according to a predetermined instruction;
a control unit;
and
control system interface means, provided to the connectionless data processing station and being coupled between said control unit and said monitor means and said switch interface means, for communicating control information between said control unit and said monitor means and said switch interface means to control said monitor means and said switch interface means.
