摘要： An improved telephone system (10) over a single telephone line within a residence or other building is disclosed, supporting exchange features and enabling easy expansion for multiple external lines. The existing telephone wiring is used as the medium for a local data communication network, carrying mutiple voice channels. In each outlet (88a, 105a), one or more voice channels are converted into a standard telephone-line interface. Life-line functionality is facilitated by using the lower band of the spectrum isolated from the data communication network, and a dedicated connector (91) in the outlet provides access to this band. External telephone feeders (86a, 86b) are converted to digital form for interfacing to the in-home data communication network.

摘要： This invention relates to a method to establish a conference connection between a plurality of conference nodes (2, 4, 8) arranged in a telecommunication network (1); and also to a node design (30; Fig 3) of such a conference node. The conference according to this invention is set up on a per call basis. Any of the conference nodes (2, 4, 8) shall, each time it activates, access a free information resource (11) among a plurality of resources (11, 12,...,n) and transmit it's message to this resource; while all the conference nodes during all the conference time, are listening to the messages present on all the activated or occupied resources. The maximum number of active (i.e. transmitting) conference nodes correspond to the total number of information resources. The maximum number of passive (i.e. listening) nodes are unlimited. A node is typically moving from a passive state to an active state and back again to the passive state leaving the resource unoccupied. Each resource may preferably be designed as a ring connection via which all the conference nodes are interconnected as the ring is looped through passive conference nodes, but where each activated ring connection is broken, only at one place, but in a dynamic manner, at the input of the active node associated with just this ring, which active node accesses this particular resource during the activated time period of just this node. The invention is well suited for digital crypto conferences, as speech decoding and decrypting is undertaken at each conference node input, while encryption and speech coding is done at each conference node output. In addition the invention is easily adapted to an Integrated Services Data Network (ISDN). Echo suppression, as well as addition and subtraction of conference signals, are totally avoided. The crypto keys to be used in such a crypto conference, may be distributed among the conference participating nodes before the conference starts; and/or they may be altered during the conference, in short lasting pauses in the conference, or on a free resource, or via the D-channel in the ISDN implementation.
摘要翻译：本发明涉及一种在电信网络（1）中安排的多个会议节点（2,4,8）之间建立会议连接的方法。并且还涉及这种会议节点的节点设计（30;图3）。根据本发明的会议是按每个呼叫建立的。每个会议节点（2,4,8）每次激活时，都要访问多个资源（11,12，...，n）中的空闲信息资源（11），并将其发送给该资源 ; 而在所有会议时间内的所有会议节点，正在监听所有激活或占用的资源上存在的消息。活动（即发送）会议节点的最大数目对应于信息资源的总数。被动（即收听）节点的最大数量是无限制的。节点通常从被动状态移动到活动状态，并且再次返回到被动状态，而将资源置于空闲状态。每个资源可以优选地设计为环形连接，当环通过被动会议节点循环时，所有会议节点都被互连，但是每个激活的环路连接仅在一个地方而是以动态的方式在与该环相关联的主动节点的输入，该活动节点在该节点的激活时间段期间访问该特定资源。本发明非常适用于数字加密会议，因为在每个会议节点输入端进行语音解码和解密，同时在每个会议节点输出端进行加密和语音编码。此外，本发明容易地适用于综合业务数据网（ISDN）。完全避免回声抑制，以及会议信号的加减。在这样的加密会议中使用的密钥可以在会议开始之前分配在会议参与节点之间; 和/或可能会在会议期间进行更改，短暂持续暂停会议或免费资源，或通过ISDN实施中的D-channel进行更改。

摘要： This invention relates to a telecommunication system including a conference information system including a number of participants each equipped with a separate node (2, 4, 8), which conference nodes may be interconnected via a switching network (1) such as a public switched telephone network, and where each participant node (2, 4 , 8) is including means for receiving a sum conference information signal from the other participating nodes, means for adding the signal generated in each conference node to the sum signal, and means for controlling the conferencing functions.
According to this invention all of the nodes (2, 4, 8) in the conference connection are interconnected in a complete conference ring (11) by means of one single connection (12) in which the information signals are transmitted from node to node in one single direction (arrow 12).
Some of the advantages of this system are

a conference may be established even if the possibly centrally arranged exchange is not provided with a conference facility.
The conference facility is introduced by equipment distributed in each node terminal.
The line requirement is reduced to the half, but still the same traffic capacity may be handled by the system.
all the nodes now get identical status in the ring, and therefore all of the nodes may be designed as quite identical circuits.

摘要： A system for selectively serially coupling a plurality of data stations into a single communications path includes a plurality of tap boxes (TBA) serially coupled into said path. Each station is coupled to a desired associated one of the tap boxes by way of an associated tap cable (TC). When the tap cable (TC) is connected to a first portion (75) of the tap box (TBA), a first impedane (79, 81) corresponding to the characteristic impedance of the single communications path is serially coupled into said path to enable the station associated with the tap cable to be coupled to said path by way of the first impedance (79, 81). When the tap cable (TC) is connected to a second portion (73) of the tap box (TBA), the first impedance (79, 81) is effectively removed from the single communications path and a test impedance (77) is coupled to the tap cable to enable the station associated with the tap cable to test itself.

摘要： A communications system that improves upon the availability of communications paths between devices and simplifies the connectivity requirements to communicate data and control information to and from a remote station (11). System nodes (21) are provided which are disposed along a time multiplex network signal stream. The nodes (21) serve to interface remote stations (11) to the network signal stream (25A, 25B) and may also switch information to different stations (11) connected to the same node (21). The nodes (21) are operative to allocate a variable bandwidth of the network signal stream for data communications between devices connected to different nodes. The nodes (21) include switching devices that may be configured to accomodate stations (11) that operate at different speeds. Allocation of bandwidth may be dynamically varied such that system resources are not unneccessarily diverted. Control of bandwidth allocation and internal switching within the node is accomplished via control information communicated to and from the node. Such control information may be contained within the network signal stream and decoded by the node (21) or communicated to the node (21) via a dedicated control communications line. Control information may be encoded into the signal stream communicated between the system node (21) and the remote station (11). Thus, communication of data and control signals between the stations (11) and the system node (21) does not require complex wiring. Accordingly, individual stations (11) may be more conveniently located.

摘要： The present invention relates to a communication system comprising a plurality of communication units (1, 2, 3) which are coupled together by coupling means (4), for example in the form of a physical conductor. Each unit is provided with first means (10) for receiving auditive information and/or second means (11) for transmitting auditive information. Certain units are allotted a group assignment and are arranged to establish a conference call facility, where an analogue signal deriving from transmitted auditive information is subjected to a sampling process. For the purpose of transmitting auditive information and/or for receiving auditive information, all units (1, 2, 3) associated with the group are arranged to utilize one and the same time slot (t3) in a time frame used for the sampling process, such that when information is transmitted simultaneously from two or more units (1, 2) the sampling contributions are summated within time slots (t3) via the unit-interlinking-means (4), so that a plurality of information signals can be evaluated simlutaneously via the first means (10) of the unit (3).
