Abstract:
Disclosed are call processing methods which are performed by a network terminator located at a subscriber's premise. The network terminator is coupled to a digital network and a communication device at the subscriber's premise and can perform call waiting, caller identification, call conferencing without intervention from a telco's switching system that requires an additional charge to the subscriber for these services. In addition, the network terminator can perform a method which allows two digital communication devices coupled to one S-bus to share a communication session. In another embodiment, up to a six way conference call can be established with an analog telephone coupled to an ISDN network via the network terminator of the present invention.
Abstract:
A technique is disclosed for use in conjunction with an ISDN communications system for permitting a host computer, that is executing a host session with a user and is connected through the system, to dynamically change an ISDN access path, that connects the user to the host computer and carries the host session therebetween, between a packet switched connection and a circuit switched connection during the occurrence of the session in order to provide the particular connection that is most suited to the communication requirements of a task currently being executed during the session by the host computer. Any such dynamic change of the ISDN access path is invoked by the host computer, does not disrupt the host session and is substantially transparent to the user.
Abstract:
An ISDN interface is provided on a card, which is adapted for mounting in a terminal computer and which is operable to exchange data with a terminal computer and an ISDN. The ISDN interface card includes a protocol processor that is programmable to process data encoded in accordance with a number of different protocols and a digital signal processor that is programmable for data compression, encryption and facsimile applications, and u-law and a-law conversion, among other applications. The ISDN card dynamically allocates data calls between one or two B-channels to achieve a data transmission rate of 128 kbps. A power supply with a ring generator is provided to allow for the use of an analog telephone with the ISDN card. The ISDN card is programmable to allow users to create customized screens for various call processes, and to allow for the updating of a flash ROM coupled to the protocol processor through the terminal computer and the ISDN.

Abstract:
A method and at least one subscriber station utilizes a software package in combination with at least one terminal adapter which links ISDN circuit-switched channels, such as "B", "H0", "H10", "H11" and the like, into a single logical connection and synchronizes the linked channels in an ISDN system. The station allows a subscriber to dynamically select various bandwidths (i.e. different channels) for data transfer, such as text or graphics. The software package and, preferably, multiple terminal adapters, reside on a personal computer and also permits simultaneous messaging and voice functions between several such subscriber stations. Any number of logical channels can be managed. ISDN data is segmented based on the channel's respective data rates and thereafter simultaneously sent on the channels of the logical connection. ISDN data is consequently transferred at a rate greater than the rate available on any single ISDN channel.
Abstract:
A network receives a connection request, from a wireless device, that includes a first Access Point Name (APN) that is invalid in a first wireless carrier network. The network device translates the first APN to a second APN that is valid in the first wireless carrier network. The network device uses the second APN in signaling associated with a connection between the wireless device and the first wireless carrier network.
Abstract:
A method and system for wireless communication between a moving vehicle and a remote server through at least one external mobile network are disclosed. The at least one exterior mobile network provides at least two concurrently useable data links. The method includes: providing at least one router in the moving vehicle for receiving and transmitting wireless data communication to and from a stationary communication server outside the moving vehicle through the at least one exterior mobile network; evaluating the quality of the data links on a host layer by repeatedly sending requests arranged to trigger a determinable automated response to the stationary communication server via the data links, and measure the time until the triggered automated responses are received; and assigning data streams to the data links at least partly based on the evaluated quality.

Abstract:
The invention relates to a circuit arrangement for the integration of EDP stems in the use of telephone installations which are connected to the public ISDN or Euro ISDN telephone systems. The aim is to connect a telephone installations to an EDP installation in such a way that all the functions of the EDP system can be used during the use of the telephone installation. This aim is achieved by using a circuit arrangement consisting of: the telephone sets (2;11;13) which are directly connected to the public ISDN or Euro ISDN telephone system (1) via a line (a) and an intelligent telephone installation (3); and an integration component (5) which is arranged between the intelligent telephone installation (3) and the personal computers (4; 12; 14), on the one hand receives signals via the SDLC or ISDN connector (8) by means of line (b) from the public ISDN or Euro ISDN telephone system (1) through the intelligent telephone installation (3) and send signals back to the public ISDN or Euro ISDN telephone system (1), and on the other hand transmits a set of data having suitable information via line (c), an LAN (9) which is connected via line (d) to the LAN server (10) and line (c) to the personal computers (4; 12; 14) and receives the set of data back from the personal computers (4; 12; 14). The conversion of the signals into the set of data and vice versa is performed by the integration component (5) via a computing system (6), a software layer (7) and an SDLC or ISDN connector (8) with internal software.
