Data transfer method for broadband integrated services digital network and broadband integrated services digital network using the data transfer method

摘要

A broadband integrated services digital network includes a network (104), first and second terminals (101, 107), and first and second terminal adapters (102, 105). Each of the first and second terminal adapters includes a buffer (103, 106) storing a predetermined number of bursts of data from either the first or second terminal and storing a predetermined number of bursts of data from the network, and a first part (134, 126) for sending ready notification information to the network and for receiving the ready notification information from the network. The ready notification information shows that the buffer has an available storage capacity equal to at least one burst. Each of the first and second terminal adapters further includes a second part (121, 136) for sending ready information to the corresponding one of the first and second terminals before the first part receives the ready notification information from the network. At least, one burst is written into the buffer each time the ready information is sent.
