COMMUNICATION SERVICE SYSTEM

摘要

PURPOSE:To simply offer the communication service to users despite several types of service available with a common node device or the change of the service by reading a service program out of a storage means and writing it into an information recording medium. CONSTITUTION:A desired service program is read out of a storage means 14 of a node device 1 and sent to the terminals 21 - 2n and written into an information recording medium 6 just by setting the medium 6 to the information recording medium access means of the terminals 21 - 2n and inputting a request of a prescribed service program via an input means 26. Such operations are carried out when the service of the device 1 is changed or different types of service are desired. Thus a desired service program is stored in the medium 6. Thus it is possible to secure the desired service with a simple operation even though the several service levels are available with a common node device or the service levels are changed.
