KR950023142A - Subscriber Network Circuit Switching Method for Data Communication - Google Patents

Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subscriber network circuit switched method for data communication, and more particularly to a method capable of flexibly coping with the addition of a service or an increase in the service amount in a data circuit switched method using information on a subscriber's data service registration status.

In general, the speed of the output signal is inversely proportional to the number of subscribers compared to the speed of the input signal, so if the subscriber wants additional services or the amount of signal sent to each subscriber increases, such services cannot be accommodated or at least the distributor hardware. Since this needs to be largely modified, such a problem is difficult to keep up with the ever-changing subscriber's information needs, and there is a problem in that there is little flexibility due to the change of service contents.

In view of the problems of the related art, the present invention uses a splitter using a time division switch and a space division switch in order to transmit a signal without a difference in speed between an input and an output. It can be distributed to each subscriber without a lot of time, and this extra can be used to provide additional services or increase the amount of data, it is characterized by the flexibility of service changes.

In other words, using a splitter that distributes the speed of the input signal to each subscriber without change, the speed delivered to each subscriber is not changed.

Claims (3)

It consists of a time-sharing switch 21 and a space-sharing switch 22 to secure the redundant data area of the output signal by eliminating the difference in transmission speed between the input signal multiplexed with the data of multiple subscribers and the output signal containing only one subscriber's data. Actively cope with data service addition or increase of service volume through distributor 20, and receive information about subscriber service registration status for switching control of distribution switch from total system control 23 'of circuit switched system. Subscriber network circuit switched system for communication. The time distribution switch 21 of claim 1, wherein 30 time frames are input for each input signal inputted in the CI frame format, and each time slot of the input signal is assigned to 30 CI frames to generate an output signal. )Wow; Subscriber network circuit switching method for data communication comprising a space distribution switch (22) which serves to map signals from the time distribution switch (21) to any number of subscriber transmission paths. The data communication according to claim 1, wherein information on the subscriber service registration status is not directly provided from the overall system control 23 'of the circuit switched system, but directly from the ROM 23 "inside the central processing unit 23. Subscriber network circuit switched. ※ Note: The disclosure is based on the initial application.
