Edr Application Example - ZyXEL Communications U-336S User Manual

Bits
EDR detection (either CNG or DTMF tones) will be disabled once
detection occurs. 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.
The timing relationship between the Caller ID (if enabled), EDR,
and ring detection is as follows:

EDR Application Example

If we use ZFAX as our fax receiving application and we don't want
it to answer the call unless it is a fax call, the way to set it up would
be:
1. Set ZFAX to answer on 2 rings.
