METHOD FOR TRANSMITTING HDLC FRAME SETTING INFORMATION IN A FRAME RELAY LINE CARD OF AN ATM EXCHANGE

摘要

The present invention relates to a method for transmitting HDLC frame setting information in a frame relay line card of an ATM device, and more particularly, to a method for transmitting HDLC frame setting information in a frame relay line card of an ATM device which enables more effective HDLC frame setting management. The method of the present invention is based on a scheme of inserting HDLC frame setting information into user information for transmission and setting a path on a trunk for user information. The trunk path setting can be accomplished by using the function of extracting HDLC frame setting information from user information and the time division multiplexing function. With the trunk path setting, a network controller in a central station can allocate any time slot in a trunk for user information and transmit HDLC frame setting information originating from an ATM device frame relay line card, without having to use a separate communication route.
