Abstract:
1. A telephone adapter comprising: a plurality of ports for connecting a group of customer appliances to said adapter; a controller having an interface for connecting, through an entry point to a network, to an ISP; and a priority-imposing module that where at least some of said ports are physically distinct ports, and where at least one of said physically distinct ports (herein referred to as POTS port) is adapted for connecting to a POTS telephone, said adapter further comprising a series connection of an A/D/A module; a CM/UNCM module; and a D/IP/D module; where said A/D/A module converts analog signal received at said POTS port to digital signal, said CM/UNCM module performs speech compression on said digital signal of said A/D/A module to form a compressed signal, and said D/IP/D module converts said compressed signal to IP packets; and where said D/IP/D module converts IP packets destined to said POTS port to a digital signal, said CM/UNCM module performs speech decompression of said digital signal of said D/IP/D module to form a digitized analog signal, and said A/D/A modules converts the digitized analog signal to output analog signal, and applies said output analog signal to said POTS port.
