ABSTRACT:
A method of forming a V.90 connection on an all digital connection. The method includes transmitting a request to connect from a digitally connected client modem (28) to a digitally connected server modem (24) and transmitting, by the client modem (28) to the server modem, a message requesting to form a V.90 connection, identifying the digitally connected client modem (28) as an analog connected modem.
