Setting Up EDR
The new EDR can be used at home where multiple phones are installed in
parallel. Once this function is enabled, the modem will go into EDR mode after
the ring disappears, and it will be able to detect the data/fax CNG tone and
DTMF tones, and report them as different types of rings. The EDR settings are
defined in S-register S51.

EDR detection (either CNG or DTMF tones) will be disabled once it . However,
a customer’s program might not answer because the setting of the software may
require multiple rings to answer. S51 bits 0-1 control the number of rings that the
modem will report once the CNG or DTMF tone is detected.
