Usage/Comments
Sets this switch to "0" if the ring tone of remote unit
is mistaken for a busy signal.
7200 9600 14400
Re-enables echo suppression that is disabled by the
CED signal (2100 Hz). Also ignores the first DIS
signal and transmits the DCS signal in response to
the second DIS signal.
International telephone lines equipped with echo
suppression will cut the beginning portion of the
transmitted information which may cause the
receiver not to receive the training and data. To
protect the received image from degrading, a 0.5
second Echo Protect tone is placed prior to the
training using G3 high-speed modem training
(V.29).
