Abstract: Conformance with established standards and interoperability between products in an integrated services digital network (ISDN) system defined by a layered hierarchy of interrelated protocols is ascertained by remotely testing the protocols between a tester in a local testing centre and a system under test located at a geographically removed site. The protocols tested relate to the first three layers of the system which are concerned mainly with the establishment, holding and release of a telecommunications path. Cost effectiveness in product testing is achieved by accessing both the tester and the system under test and communicating test procedures between the local and remote sites over a packet switching network to support testing at the remote site. Communications over a virtual circuit in the network are established between a pair of remote ISDN test access interfaces, one located at each site. A communications path from a test access interface and its corresponding local tester or system under test is provided by an ISDN interface. Under software control by a computer at each site, the test access interfaces function individually to split the corresponding ISDN interface so that the network may be inserted therebetween to link the tester with the system under test.

Abstract: In access to the ISDN from LAN, two B.sub.1 and B.sub.2 channels in the TDM signal in the ISDN are predetermined to be corresponding to the packet and the line switches in the ISDN switch. The packet data from LAN are transmitted through a virtual circuit on B.sub.1 channel through the packet switch to a called party under the call control on D channel. When the data packet from the LAN per a unit time is increased, another virtual circuit is set up on B.sub.2 channel through the line switch by a call control on D channel in response to a channel change signal. Then, the virtual circuit on B.sub.1 channel is cleared. Thus, the increased packet data is transmitted on B.sub.2 channel and through the line switch to the called party without interruption of data transmission.

Abstract: A packet switching method in a digital network includes a calling equipment and called equipment connected to the digital network for communication by packet switching, and further includes a destination end system to be connected to the called equipment for communication. Upon occurrence of a call demand by the calling equipment, a sub-address of the called equipment and a network address of the destination end system are inserted in a call demand packet and the call demand packet is transmitted to the digital network. Upon reception of a call setup message by the called equipment from the digital network which receives the call demand packet, the sub-address from the call setup message is extracted and a judgement is made as to whether the incoming call is designated to own equipment by checking matching of the extracted sub-address and a given sub-address assigned to own equipment. A response message to the digital network is transmitted when the incoming call is judged to designate own equipment. Upon the called equipment's reception of an incoming call packet which was transmitted by the digital network after receiving the response message, the network address from the incoming call packet is extracted and incoming call processing is performed based on the extracted network address for establishing the call.

Abstract: An improved Packet Assembler/Disassembler (PAD) optimizes the assembling of characters into packets for transmission over a packet network. The PAD is arranged to operably connect to and receive character asynchronous data from one or more terminal instruments operating in either a block transfer mode or an echoplexing mode. Characters received by the PAD from a terminal instrument operating in an echoplexing mode are forwarded with no PAD delay. Characters received by the PAD from a terminal instrument operating in a block transfer mode are similarly forwarded with no PAD delay and in full packets with the exception of the last few characters of each block of characters which only partially fill their respective packets. And these partially filled packets are quickly forwarded in a time period which just exceeds the period required for the reception of a single character at the rate of data reception from the terminal instrument.

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: A method and system are provided for connecting and billing a first user on an Integrated Services Digital Network to a second user on a voice-band network for packet data and circuit switched data connections. A network access device is used to extract the first user's billing information and the called party's phone number from the data packets received in the case of data packet transmission and call set-up messages received on an ISDN interface in the case of circuit switched digital connections. A voice-band call to the second user is transmitted over the voice-band network. The billing identification sent by the first user is used to bill the first user for the voice-band call established from the network access device over the public switched telephone network to the second user.

Abstract: A concentration method and concentrator arrangement enable a plurality of synchronous or asynchronous data terminals to be served by a common B channel of an ISDN to which the data terminals are connected by a digital subscriber termination and terminal adapters for transmission in packet mode. The terminal adapters are connected to the digital subscriber termination at the S0 basic access level. In the event of a request for B channel communication between a first data terminal served by a first terminal adapter and a packet mode ISDN port to which a second data terminal already has access via a second terminal adapter and via a first B channel, a transit connection is established between the two terminal adapters via the digital subscriber termination using a second B channel. Data packets conveyed between the first data terminal and the ISDN port are conveyed via the terminal adapter of the second data terminal.
