Methods and apparatus for controlling digital communications switching equipment

Abstract

A “generic” switch messaging protocol is disclosed for message handling and switch supervision in conjunction with a number of switching engines, each of which is conversant with the generic messaging protocol, each switching engine also being conversant with a specific switch messaging protocol. An object oriented development system is also disclosed utilizing a “generic” switch messaging protocol and a plurality of switching engines, each of which is conversant with the generic messaging protocol and each of which is conversant with a specific switch messaging protocol. Certain switch messages are not “genericized” because their functionality is different from the functionality of other switches. These messages generally include initialization and maintenance messages which are hardware specific and have no counterpart in another switch from a different vendor. In order to handle these messages, specific data files are provided in the switching engine for automatic download to the switch as well as a specific MML for interpreting configuration commands. Also, according to the invention, some commands or messages which are not otherwise supported by a particular switch can nevertheless be supported in the API by providing the switch engine with the intelligence to combine native switch messages to “emulate” a functionality which is not directly provided by the switch.

Dependencies are inferred from the claim text.
