Abstract: A method and system for updating a replicated database  of  a  telecommunications  network  system  is disclosed.  The database in a network system improves cost, setup time and system availability.  A call transport system has switches for forwarding calls from a local telephone station through the call transport system to a destination. A signaling system is operatively connected to the call transport  system and includes a primary site databases within the signaling system containing customer records for call routing and other signaling functions and at least one secondary site database containing the customer records of the primary site database.  Both primary and secondary site database maintain multiple versions of the same customer record so that queries of a call can use a version number to access the corresponding version of the record in the same database  for  consistent  routing  and  other  signaling information. A customer record is updated in the primary site database and then information concerning the updated database record is transmitted through the signaling network to the secondary site database containing the replicated version of  the  record.   The  records  are  then updated according to the sequence of the version number.   The processing of all calls querying the previous version of the primary and secondary site database record are completed before  the previous version of  the database  record is deleted.

Patent CA-2182730-A1 (CA)
Inventor: KAELIN RUEDI
IPC: H02J3/14
Filed: 1996-08-05
Abstract: A transformer, typically a miniature transformer, to provide low-voltage power between, usually, 2 to 12 V from a power network has an auxiliary winding (6) inductively coupled to the core (9) of the transformer. A reference signal is provided from the power supply, and a monitoring circuit (32), which includes a difference-forming circuit (16) is coupled to receive (a) a signal from the auxiliary winding (6) and (b) the reference signal, the difference-forming signal providing an output in dependence on the state of magnetization of the core, by evaluating differences in magnetization (.DELTA.B) depending on whether power is being supplied by the transformer, or not.  A circuit interruption element (10), typically a transistor, is serially connected between the power supply (1, 2) and the transformer. To determine if, after disconnection, the load should require power, for example if the load is a user-operated appliance, or a rechargeable battery, periodically requiring recharging even if the battery is not in use, an interrogation circuit (30) is coupled to the power supply to periodically, or aperiodically, based on time, or on the value of a physical parameter, reconnect the transistor (10) for a brief interval, in the order of milliseconds, to permit determination if power is being required, or not.  If power is required, the transistor will remain conductive; if no power is required, however, the circuit will again control the transistor to non-conduction, thereby saving magnetization current flowing into the transformer if there is no need, based on required power.
