Abstract: PURPOSE: A method for controlling an ATM(Asynchronous Transfer Mode) SVC(Switched Virtual Channel) connection of an ADSL(Asymmetric Digital Subscriber Line) system is provided to classify and manage a bandwidth use and the number of the ADSL users by the hour zone, and determine acceptance and rejection of the connection on the basis of the classified time zone when requesting a new connection. CONSTITUTION: A user number management unit divides 24 hours of a day by an interval of three hours and manages 8 data relating to the user number of 8 time zones. Also, the unit divides three sections of a week such as ordinary days, Saturday and Sunday. Accordingly, the unit manages total 24 data. Each data unit searches the number of users by an interval of 5 minutes, averages the searched data at every three hours and then stores it to a storage device such as a memory or a database and the like. So, data relating to the number of the connection formed by each user is constructed(S31-S32). A bandwidth management unit averages arithmetically the data of the connection provided to each user and calculates an average data transmission rate and a new standard deviation(S33-S34). When a new connection request is inputted, a CAC(Connection Admission Control) unit compares the number of users at the corresponding time and a day of the week with the current number of users with reference to the data relating to the managed user numbers(S35-S36). If the number of the current connection is less than that of the existing data, the new connection is accepted.
