摘要： An improved reed relay having a bobbin, an operating coil wound around the bobbin and at least one reed switch contained within the bobbin. The reed switch has a hermetically-sealed glass capsule that contains an atmosphere of dry inert gas. The capsule also contains two long thin contact blades having terminations extending from respective ends of the capsule. A first contact blade acting as the armature is formed at its contact end with multiple prongs, each prong containing a contact pad. The second contact blade acts as the fixed contact. The contact pads surround the contact end of the second blade so as to contact, during operation of the relay, a different surface area of the second blade. The prongs may be formed in any desired geometric arrangement (e.g., rectangular, triangular, etc.) to surround the contact end of the second contact blade.

摘要： A method of establishing a contact arrangement for a reed switch. The method increases the number of contact surfaces between the armature and the fixed contact by providing the fixed contact with a contact end that has multiple prongs and positions the armature and the fixed contact so that the prongs surround the armature. The method also adjusts the armature and the fixed contact so that there are prongs that contact the armature when the armature moves from the rest position during switch operation and prongs that provide additional multi-planar contact surfaces for the armature in the event that the armature and the fixed contact prematurely separate during switch operation.

摘要： A telephone wiretapping system having a call-forward event and reporting processor for producing a call-forward event control signal when a call from a calling party to a predetermined telephone line is to be call-forwarded to a different telephone line. A switch is responsive to the control signal produced by the call forward event and reporting system for switching the recording device from the target telephone line to the call-forward event and reporting processor when the control signal indicates a call-forwarding event. With such an arrangement, the recording device will recorded calling event signals to, or from, the target telephone line even though the calling event signals are occurring at the call-forwarded telephone line. The call-forward event and reporting processor produces signalling information taking place between the telephone line of the calling party and the telephone line of the different, call-forwarded telephone line. The switch couples the signalling information taking place between the telephone line of the calling party and the telephone line of the different, call-forwarded telephone line produced by the call-forward event and reporting processor to the recording device when the call-forward event control signal is produced. A tone generator is coupled between the switch and the call-forward event and reporting processor for producing a predetermined tone for the recording device when the switch couples the recording device to the call-forward event and reporting processor. The predetermined tone is a "fourth" column DTMF tone.

摘要： A device for operating lamps, such as fluorescent lamps includes an input protection circuit, a filter, a DC to DC converter, a power output stage, a lamp connecting circuit and a control circuit. The control circuit includes a pulse width modulator, a multivibrator and a start/stop controller. The pulse width modulator varies the duty cycle of a control signal supplied to the DC to DC converter based on a feedback signal from the DC to DC converter. The multivibrator assists in the control of the DC to DC converter. The start/stop controller initiates the operation of the power output stage when an output of the DC to DC converter reaches a predetermined level and halts the operation of the power output stage if a failure is detected.

摘要： A distributed database management (DDBMS) system for switching applications that combines rapid feature deployment with high real-time performance. The system architecture encompasses a new software boundary between application and database, yet provides the benefits of open standard interfaces and distributed transaction control. To accomplish this dichotomy, an object-oriented schema is used to arrange the DDBMS as an intelligent service provider, separating services from physical location and implementation. A software containment approach is utilized to optimize interfaces based on grouping of data so as to permit application-specific routines to be "plugged-into" the database. The DDBMS is arranged to address extendibility and real-time performance needs of capabilities such as ISDN and IN is switching offices and network nodes.

摘要： A method for enabling a plurality of Local Service Providers within a common Numbering Plan Area (NPA) to serve Subscribers of the plurality of Local Service Providers. The method includes the step of assigning to each Subscriber of a Local Service Provider within the common NPA a unique three digit code, hereinafter referred to as a service provider area (SPA) code. The SPA code is used by the telephone system in the same manner presently used for routing calls made when a calling Subscriber dials the NPA code of the called party. Here, however, the SPA code is not dialed by the calling Subscriber. The dialed directory number, NXX-XXXX, of a called Subscriber subscribed to a different Local Service Provider, is sent to a database. The database maintains a record of the relationships between the directory numbers of Subscribers and the SPA codes of the Subscribers. The database retrieves the SPA code associated with the dialed directory number presently serving the called Subscriber. The call is routed as SPA-NXX-XXXX. Because the ten digit format, SPA-NXX-XXXX, is the same as the present NPA-NXX-XXXX, ten digit format, existing signaling and routing mechanisms may be used to route the call. Thus, each one of the Subscribers of each one of the plurality of Local Service Providers is assigned a common SPA code, each one of the Local Service Providers having a different SPA code.

摘要： A device for enabling automatic restoration of network access for user lines within a communication system. The user lines interface with groups of transmission lines that include dedicated transmission lines which are connected to the user lines, idle transmission lines and reserved transmission lines. The device includes a line manager that makes a number of transmission lines among the groups of transmission lines available for user lines which have a dedicated transmission line in a group of transmission lines that fails and a reprovisioning element that couples each of such user lines to a respective available transmission line. The device may also include a monitor that delays the coupling of such user lines if a sufficient number of transmission lines are not available.
