International ClassesH04M 003/42H04M 001/00 AbstractThis invention relates to a method and apparatus for signaling telecommunications customer requests to a switching system. The basic signaling arrangement consists of a series of function calls, including a function type specifier and an optional parameter of the function. Function calls are separated by delimiters which are strings of characters, such as ** or *#, that are unique and not to be confused with function type specifiers or parameters. Strings of function calls can be stored in a switching system and can be called by a speed calling request. The function types include types wherein a customer supplies a parameter, such as a personal identification code in an otherwise prespecified string of function calls.Other References
