H04M 1100
US Classification:
379 9314, 379 9308, 375222
Abstract:
A method and apparatus are provided for efficient improved data transmissions on telephone links between service providers and remote clients. The method and apparatus perform the steps of receiving an analog encoded data signal, selectively routed by a switch which is communicatively connected to a set of central office switch assembly codecs, and performing a high precision, synchronized analog to digital conversion while the signal is relatively close to a phone company central office switch assembly. The signal is transferred to output circuitry used to transmit signals on phone company subscriber lines. The signal is converted back to an analog signal prior to its final transmission to a subscriber client modem. In an embodiment of the invention, the high precision, synchronized analog to digital conversion is performed by a client-type modem and the output is transferred to a server-type modem which transmits the converted signal, in digital form, over a pair gain system. In an alternative embodiment, the client-type modem resides on the central office terminal side of a pair gain system and the server-type modem resides on the remote terminal side of the pair gain system.
