Abstract
A programmable modem or PSTN interface whose electrical characteristics can be programmed by software to satisfy multiple international telecommunication standards is implemented. Specifically, this modem configures a data access arrangement (DAA) circuit to provide a telephone connection having characteristics suitable for each unique country standard, without requiring the DAA to be replaced or to have any hardware modifications. Furthermore, the required changes to the DAA may be made "on the fly" during homologation testing.
