    Abstract: A wireless in-building telecommunications system for voice and data communications is disclosed having at least one node (101) arranged for linking to the PSTN (151) and at least one digital information source (153, 155, 157, 159) multiplicity of user modules (103) (UM's) linked to the node via a shared RF communications path (107). Each UM is coupled to a voice telephone instrument (127) and to one or more data terminals (165). The UM's communicate with the node by exchanging fast packets via the common RF path (107). The node also includes a fast-packet-switched mechanism controlled by a bandwidth allocating scheme to prevent collisions of packets as they are transmitted between the various units (101, 103) (nodes and/or user modules) that may be accessing the RF path (107). Also disclosed is a method for allocating the required bandwidth to each of the users of the common communications path in a wireless in-building telephone system. The invention provides for the combination of both voice and data in a single switch using a common packet structure. It allows for the dynamic allocation of bandwidth based on system loading. This includes not only bandwidth within the voice or data areas of the frame, but also between the voice and data portions. It also synchronizes the transfer of the data and the allocation of bus bandwidth.

    Abstract: A line interface circuit (120) receives an audio signal from a signal generator (132). A reflected signal is produced at the output port (216) of a SLIC (210). The reflected signal is combined with the received audio signal to produce a combined audio signal. The combined audio signal is measured to determine if a fault exists in the subscriber loop (130).

    Abstract: In a network of interconnected wireless networks (NODE, UIM) and wired telephone networks (PSTN, PBX), there is provided a mechanism for sustained association of users with communications paths. It is characterized by: upon an attempted use of an unassociated telephone, identifying oneself to the network (via the wireless network) and activating one's telephone line (pair 1, 2, 3 . . . n) by keying ones' own telephone number (12345, 12346 or 12347) through the telephone keypad, locating his telephone line (12345, 12346 or 12347) by monitoring unassociated lines (pair 1, 2, 3 . . . n) for activity, and the one so identified receiving a sustaining association (for more than a few communications) with the telephone line (pair 1, 2, 3 . . . n and UIM) so located.

    Abstract: The system includes a line interface circuit, to which a signal analyser is linked measuring a combined audio signal to determine if a fault exists in the subscriber's loop defined by the subscriber's building network and the line interface circuit. The line interface circuit generates the combined audio signal by combining a reflection and the reception audio signal. Preferably, the signal analyser measures the combined audio signal to determine if a fault is present in the subscriber's building network. Typically the reflection signal depends on an impedance at a signal ring line gate of the line interface circuit.
