  • Mechanism for conducting in-band communications between terminal adapter and digital terminal device during internet session
    Patent number: 6928071
    Abstract: A communication control mechanism installable in the communications controller of an ISDN terminal adapter is operative to conduct in-band communications with its digital terminal device during an internet communication session between the digital terminal device and a digital communication network interface of an internet service provider. The terminal adapter monitors the data link establishment communication exchange between the network access server and the personal computer, to identify and capture internet protocol addresses for the digital terminal device and the network access interface. These addresses are then used by the terminal adapter to communicate in-band with the digital terminal device using user datagram protocol (UDP)-based messages.
    Type: Grant
