Special Functions 61

Bits Bin. Dec. Description

11 3 Report RING six times.

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:

ring1 ring2 ring3

***--------***--------***------------------------------

3sec 3s 3s 3s S7 time-out

ONOTE: DURING THE EDR PERIOD, ANY AT COMMAND WILL DISABLE THE EDR

FUNCTION.

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.
