摘要:
A multilingual operation and maintenance interface for a telecommunication exchange. The interface includes a plurality of modules and a plurality of resource files. Alphanumeric information in a different target language and related to interactive communication with the interface is included in a resource file. At least one resource file is an intermediate language file including intermediate language information other than alphanumeric information in a target language. An external device is provided to display a control response of the operation and maintenance interface in the target language.

A telecommunication network may be arranged in accord with the invention so that a change in provisioning data occurring at one element of the network is automatically supplied to the other elements of the network, thereby eliminating the need of having a network administration facility to communicate manually the change to the other network elements. For example, if a local central office switch is rehomed from a first toll switch to a second toll switch, then the first and second toll switches form messages respectively characterizing the rehome and then send the messages to each of the other network toll switches so that the other toll switches may update their respective routing and trunking data relating to the rehomed switch. The network is also arranged to implement a rule-based, end-to-end routing scheme which automatically selects a routing path from multiple candidates based on (a) class-of-service parameters and (b) availability of network capacity. The automatic selection of a routing path thus replaces the provisioning of routing data in the toll switches, which data was priorly needed to select the appropriate routing path.

A spark-advance mechanism for an internal combustion engine is operated by vacuum pressure in the engine intake manifold. A conduit connecting the spark-advance mechanism to the intake manifold includes a solenoid operated valve which is normally open, and which is closed by either of two switches connected in parallel. One of the switches is closed when the engine temperature is low, and the other is closed when the engine RPM is high. When the solenoid valve is energized by either or both switches to close the conduit, atmospheric air is bled through an orifice to cause slow advance of the spark timing.

A system for monitoring dialled numbers is disclosed which provides a subscriber with a record of numbers dialled over his telephone line or lines. The system provides a monitoring unit inductively coupled to each line which tapes the dial pulses as they are dialled. Aslo included is a control processing unit which processes the individual tapes to provide a written record. The system thus eliminates the need for duplicating costly equipment such as discriminators and printers at each line.
