A peripheral access module transports voice and data between the common control equipment and the peripheral equipment of a telephone switch. The peripheral access module determines the protocol for transporting the voice and data, and determines the type of medium to effect the transporting. The peripheral access module operatively connects to the peripheral equipment and adaptively reside on a card of the common control equipment.

Modular digital telephone system and method including an universal telephony shelf

A modular digital telephone system and method featuring a universal telephony shelf adaptable for incremental expansion of legacy telephone switches and as a building block in the construction of new telephony switches. The shelf includes identification and connectors for shelf pairing, and is adapted to receive redundant power supplies, plural line cards, and either a peripheral shelf interface unit or a switch array card which provides both a local shelf interface and three interface units for connection to the peripheral interface units of other shelves. System wide fault displays are provided.

Device and method for expanding legacy switches

An apparatus and method for a telephone system includes a telephony switch comprising a timing and switch array card for effecting all switching and timing functions of the switch, a plurality of telephony line cards operatively connected to the timing and switch array card, and at least one power supply operatively connected to both the timing and switch array card and the plurality of line cards wherein said timing and switching functions comprise tone and conference functions, line card slot and alarm board interface functions, PCM switching functions, signal scanning and signal packet transfer buffer support functions, host computer interface functions, and clock and synchronization functions.

Shelf driver unit and method

In a wireless communication system in which a base station communicates with plural mobile stations using frames of digital data, each frame having a control slot and plural voice (or data) slots, the present invention divides at least some of the slots into two portions and receives communications from one of the mobile stations during a first portion of a voice slot and communicates with the same mobile station during the second portion of the same slot.

System for communicating digital information between a base unit and

In a wireless communication system in which plural base stations communicate with plural mobile stations using a control slot and plural voice (or data) slots, the present invention dynamically allocates which of a predetermined set of frequencies are used by a given base station at a given time. The base stations monitor the predetermined set of frequencies to determine which frequencies are being used within which slots within the range of radio reception of the base station. Currently unused frequency/slot combinations are assigned by a base station to service the next request for a voice slot.

Wireless communications system and method having dynamic reallocation of

In a wireless communication system in which a base station communicates with plural mobile stations using a control channel and plural voice (or data) channels, the present invention uses the control channel as a voice channel whenever the other voice channels are in use and a request is received from a mobile station for another voice channel. The base station's use of the control channel varies as the control channel switches from a control channel to a voice channel and back to a control channel again.

Wireless communications system and method using a reusable control

A method for routing a call to a called party who may be located at any one of plural sites which avoids delays in connecting the called party to the received call. When a call is received at a switch, a controller at the switch uses an embedded data base to identify plural sites where the called party may be located from among a multiplicity of sites to which the switch can be connected and causes the switch to initiate parallel connections from the switch to the identified sites. The received telephone call is routed through the switch to a one of the sites at which the called party responds to the initiated connections, and the initiated connections from the switch to the other of the identified plural sites are thereafter disestablished.

Method and apparatus for initiating parallel connections to identified

A system and method for readily varying the configuration of a telephone system and the functions/features available to the users of wireless telephone instruments on the system. The telephone instruments may include a display which can be configured by interaction with a base station to vary the interpretation given to inputs received from the user. Features available to the user of a particular telephone instrument may be specifically adapted to the user and may be readily modified as the user changes, as the user's authorization changes, and/or as the telephone system's capabilities are changed.

Method and apparatus for configuring dispersed components in a

A wireless PBX system utilizes base stations dispersed throughout an area to be served with wireless telephone service. The base stations utilize multiple antennae to reduce problems associated with fading and multipath. In the present invention, the antennae of a base station or similar apparatus are rotatable, at least in pairs, so that the base station may be hung vertically, horizontally, or at some other angle to the horizon and the antennae may be readily oriented to a position which provides for preferred propagation characteristics for the antennae for the local area in which the base station is mounted.

Multiple orientation, multiple antenna apparatus

System and method for operating a wireless telephone system particularly a wireless Private Branch Exchange (PBX), as both a voice system and a pager system. The system includes a protocol for communicating both voice conversations and display data to a remote unit. Remote units, which may be pagers, personal communications units, mobile telephones, and the like, communicate with the wired portion of the system using the same protocols and signalling techniques.

Multiple use wireless communications system and method

A method for combining signals for a telephone conference may include a multiplicity of identical adders for combining six signals and providing a single combined output. The adders may be arranged in a repeatable hierarchical scheme in which each group of six conference members includes an adder for combining all six signals, with the output of this adder being provided to other groups of six so that each conference member receives signals from every other conference member. As few as three hierarchical levels of addition may be used with up to 216 members. Adders may also be arranged so that a member of a first conference may monitor other conferences without affecting the first conference.
