摘要： External invocation of features on a switching system (10) from a network (18) is made possible by aliasing otherwise-unused network numbers that are assigned to the switching system within the network numbering plan to feature-access codes of the switching system's internal numbering plan, in the switching system's call processing arrangement (200) that uses stored definitions of syntax (320, 350) and grammar (400, 410) of the internal and network numbering plans. The aliasing is accomplished as follows. The syntax definitions of the internal numbering plan include definitions (312) of individual feature access codes, while the syntax definitions of the network numbering plan include definitions (312) of the aliased network numbers, which either are the same as the definitions of the corresponding feature access codes or direct the aliased network numbers to be translated into the corresponding feature access codes. In use, symbol strings received by the switching systems are parsed (210) to identify them as feature access codes or aliased network numbers, requisite translations are performed (230), and feature modules (205) that are pointed to (334) within the definitions are invoked (220).

摘要： Tone treatment given to callers by an originating switching system (10) during dialing may be customized in a call-processing arrangement (200) that uses stored definitions of syntax (320, 350) and grammar (400, 410) of the network numbering plan. The syntax definitions include definitions (312) of individual symbol strings and their associated tones (336), if any. Associations of tones with symbol strings are administratively reprogrammable to change the specified tone treatment. Following dialing and identification (340) of an individual symbol string, a caller is immediately fed back (906) the string's associated tone, if any. A caller is thus immediately advised during dialing of successful or unsuccessful input of a valid symbol string, and is selectively prompted for input of another string. Caller-perceivable feedback signals other than tones may be used with equal effect.

摘要： Any valid displayed called number may be properly visually segmented by a call-processing arrangement (200) that uses stored definitions of syntax (320, 350) and grammar (400, 410) of the whole network numbering plan. The syntax definitions include definitions (312) of individual symbol strings and their associated display demarcations (360), if any--such as spaces or dashes or parentheses--or even their associated replacement strings. Display demarcations or replacement strings that are specified for individual symbol strings are administratively reprogrammable to change the specified display demarcations or replacement string. Following dialing of an individual symbol string, the symbol string is identified and it or its replacement is displayed (986) on the display (19) of the caller's telephone set (17) along with any previously-dialed symbol strings and is demarcated therefrom as specified in the definition of the symbol string. A caller thus always receives a display of any valid dialed number either properly visually segmented into its logical components or replaced by its logical meaning.

摘要： A system for facilitating the translation of messages from an original language to a language preferred by an end user is provided. The system allows distributors, end users or others to create translated versions of messages used by an application program, while protecting against changes that might affect operation of the application program. More particularly, a new message editor application ensures that proper formatting of messages is utilized, and protects verified messages against unauthorized editing using a data conformance stamp. Before applying a new message, the application program recreates the data conformance stamp to ensure that the new message has not been altered outside of the message editor application.

摘要： Symbol sequences of varying lengths and having logical meanings other than as network addresses (e.g., subscriber names), are assigned and used as actual telecommunications network addresses, without imposition of predefined fixed lengths, formats, or orderings on their constituent segments (e.g., given name, surname), in a call-processing arrangement (200) that uses stored definitions of syntax (320, 350) and grammar (400, 410) of the network numbering plan. The syntax definitions include definitions (312) of individual address segments, called symbol strings, which have logical meanings. Each string's definition includes a string length range (332), a string type (331), and an indicator (VNI 334) of the string's influence on call treatment (e.g., route) selection. The grammar definitions include a matrix (400) that defines permissible sequences of string types, including string types (256) which cannot be dialed by users but only result from receipt of permissible sequences of strings of user-dialable types, and a matrix (410) that defines which string types' influences on call treatment selection may be combined to select a treatment for a call. A network digit analysis function (210) parses a received call-control symbol sequence by using the stored syntax and grammar definitions to select a treatment for the call.

摘要： A call-processing arrangement (200) views a network numbering plan as a language in the mathematical/computer science sense and takes a lexicographic approach to call processing. Numbering plan syntax is defined by data in tree data structures (320, 330), and numbering plan grammar is defined by data in matrix data structures (400, 410). The data structures are used by numbering plan-independent functions to determine the meaning of call-associated digit strings and to specify the treatment (e.g., routing, features,) to be given to the call based on that meaning. A string-identification function (340) applies collected digits to the trees and matrices to find leafs (312) that define digit strings that make up the number. A string-action function (341) uses the definitions in the found leafs to form a call-route-specifying or call-feature-specifying index (254) for the call. A generalized route-selection function (343) uses a set of first call characteristics including the route-or-feature-specifying index to select from multi-dimensional matrices (1200, 1202) either a feature module (205) to be invoked or a routing-pattern number (1201), and in the latter case uses a set of second call characteristics including the routing-pattern number to select a route preference (1701) from routing pattern-preference tables (1300). A digit-sending function (344) uses the route preference to select an entry of digit-sending information (1701) from a sending table (1700) and uses the sending information to establish a call path and to outpulse digits. A digit modification function (343) and a table (1000) of digit modifications are also provided for purposes of number conversion, such as between different network numbering plans when more than one is defined.

摘要： Which call feature module, if any, is invoked in response to a user's input of a feature access code is made dependent upon the context in which the feature request is made, in a call-processing arrangement (200) that uses stored definitions of syntax (320, 350) and grammar (400, 410) of the network numbering plan. The syntax definitions are definitions (312) of individual symbol strings, including the feature access codes, and include the string's associated virtual node-point identifier (VNI 334) which indicates the string's influence on feature selections. A VNI (254) resulting from the VNIs of symbol strings included in the entire symbol sequence input by a user serves, along with parameters (1230, 1231, 1232) of the context, as a multi-dimensional pointer into a matrix (1202) of feature numbers (1203). The feature module (205) which corresponds to the feature number pointed to in the matrix by the pointer is then invoked and executed to provide a corresponding call feature.

摘要： Choice of what portions of a dialed number are important and what weight they carry in deciding how to route or otherwise treat a call is customized and made contextually dependent via a call-processing arrangement (200) that uses stored definitions of syntax (320, 350) and grammar (400, 410) of the network numbering plan. The syntax definitions are reprogrammable definitions (312) of individual symbol strings and include the string's associated virtual nodepoint index (VNI 334) which indicates the string's influence on call treatment, an indicator (335) of whether digit collection is to continue, an indicator (339) of whether the VNI is to be combined with a VNI resulting from any preceding symbol strings in the dialed number, and an indicator (338) of whether the VNI resulting from this symbol string is to be combined with a VNI of any succeeding symbol strings in the dialed number. The dialed number is parsed (340) to identify therein all included symbol strings, and the definitions of the included symbol strings are used to selectively combine (341) their VNIs to form a resulting VNI that specifies the route or other treatment for the call.

摘要： Use codes representative of uses of calls are defined as a part of a network numbering plan, and a route or a destination for a call is selected in full or in part on the basis of the use code dialed by a caller in conjunction with the called number via a call-processing arrangement (200) that uses stored definitions of syntax (320, 350) and grammar (400, 410) of the network numbering plan. The syntax definitions are definitions (312) of individual symbol strings, including the use codes, and include the string's associated virtual nodepoint index (VNI 334) which indicates the string's influence on call route selection, an indicator (339) of whether the VNI is to be combined with a VNI resulting from any preceding strings in the caller-dialed symbol-sequence, an indicator (338) of whether the VNI resulting from this symbol string is to be combined with a VNI of any succeeding symbol strings in the symbol sequence, and an indicator (333) of the string's influence on destination selection that specifies whether, and how, the symbols of the string are to be modified. The dialed symbol sequence is parsed (340) into symbol strings and the definitions of those symbol strings are used to selectively combine (341) their VNIs and modify (342) their symbols to form a resulting VNI and symbol sequence that specifies the route and the destination for the call.
