摘要： Apparatus and method for enabling bilateral transmission of digital data between a local area network and telephone company networks employing both analog and digital telephone lines. A modem modulates signals responsive to signals from a local area network representing an outgoing call to form digital telephone signals suitable for transmission by a telephone line and suitable for demodulation by receiving analog modems. A circuit switched time division multiplex bus transmits the digital telephone signals to the telephone line. The modem also demodulates incoming digital telephone signals to form digital network bus signals divided into packets. A packet bus transmits the digital network bus signals to a network interface which processes the signals and transmits them to the local area network.

摘要： A method of processing incoming digital telephone calls from remotely located call originators which are destined for receipt by a host computer system. The host computer system is linked to the telephone network by a network access server. The call originators may be any type of data terminal, such as a personal computer or a credit card swipe, which is connected to a modem. The network access server extracts control signals imparted onto the telephone line and correlates the control signals with particular communications, routing or applications protocols identified with the call originators. The modem in the network access server which answers the call is configured during the call connect process and placed in a compatible format for the communications protocol of the incoming call. This dynamic custom configuration of the modem reduces the overall telephone call connection and processing time. The control signals may also be used by network access server for customized call routing or by the network access server or host computer system to run specialized application programs. The method is particularly suitable for use by large enterprises handling a high volume of incoming calls in which data is transmitted to the host computer system according to a variety of different communications protocols, or where the implementation of different routing paths or applications programs is desireable according to the identity or classification of the call originator.

摘要： A communication access chassis having a general purpose computing platform provides communication access between remote users and computer network via the public telephone network. The general purpose computing platform is connected to an internal chassis bus complex transmitting incoming calls between a telephone line interface and a signal conversion system and between the signal conversion system and a local area network interface. The computing platform has a conventional microprocessor and local or peripheral memory storage devices and implements a commercially available open network operating system such as Windows NT™. By virtue of the ability of the general purpose computing platform to run network server programs locally, i.e., in the communication chassis, server functionality that has been provided only by remote computers on a local area network in the prior art is incorporated into the communications chassis itself, providing for improved network management, increased network security and reduced access and processing time, all in a manner transparent to the remote user.

摘要： A method and apparatus for distributing protocol processing among a plurality of computing platforms. Data communications equipment such as Remote Access Devices, Communication Servers, Terminal Servers, and Dial-up Routers provide single user or large-scale multiple user communication access to various computing environments. The equipment costs and performance of levels of providing such access equipment is related to the amount of CPU processing capability and memory required to support the desired number of serial communication links. It is common to use protocols that terminate in their entirely in the same processing machine. This invention encompasses methods developed to increase the cost/performance capabilities of the communication equipment that supports these serial links, primarily by means of distributing the protocol processing across multiple computing platforms, including devices such as modems.

摘要： A method for coordinating and controlling multiple data streams representing a data transmission session that terminate in different termination units (such as network access servers). The data streams are transmitted over two or more links, collectively forming a "bundle". The termination units are linked together preferably over a local area network. One of the termination units that receives a data stream is designated as the termination unit to receive and reconstruct the call. The designated termination unit is the "owner" of the bundle. The termination unit broadcasts an advertisement consisting of a bundle mapping update packet software structure with an identification header to alert the other termination units that it is to reconstruct the call. The identification header in the advertisement notifies the other termination units that if they should receive a portion of the data stream in the bundle, they should forward their packets of data to the designated termination unit. The sharing of bundle information between the termination units gives a great deal of flexibility in the design and type of termination units that may be employed.
