This document deals with the older type of radio telephone, known as a DRCS telephone. You can easily tell what type of phone you have by picking up the handpiece. If you get a dialtone immediately then you are on the new system. If you get a couple of clicks, then a dial tone about two seconds later, you have a DRCS one. Maximum Connection is between 7200 and 9600.
Dropouts are more common than on ordinary lines.
It is highly recommended you splash out on a more capable modem such as the Banksia WaveSP or similar. These usually give a connection of 7200 and in good conditions up to 9600. Some Radio telephones take a few seconds to give a dial tone after you pick up the reciever. This can upset some modems, as they don't wait long enough for the dial tone. In this case, pick up the reciever, then after 3 seconds hit the connect button.
