Multi-Tech Systems, Inc. AT Commands for the MultiModem & SocketModem MT9234 Series (S000434H) 34

+VDR Distinctive Ring Report

Description: Enables reporting of ring cadence information to the DTE and specifies the minimum

ring cadence that will be reported.

The report format is one line per silence period and one line per ring period. The

length of the silence period is in the form DROF=number in units of 100

ms<CR><LF>, and the length of the ring is in the form DRON=number in units of 100

ms<CR> <LF>. The modem may produce a Ring event code after the DRON

message if enabled by the y parameter. The y parameter must be set to a value

equal to or smaller than the expected ring cadence.

Syntax: AT+VDR=<value x>, <value y>

Values: x = 0, 1 Distinctive Ring report control. Default = 0.

y = 0–255 Minimum ring interval in 100 ms units. Default = 0.

+VDR=0, N/A Disables Distinctive Ring cadence reporting.

+VDR=1, 0 Enables Distinctive Ring cadence reporting. Other call progress

result codes (including RING) are reported as normal.

+VDR=1, >0 Enables Distinctive Ring cadence reporting. The RING result code is

reported after the falling edge of the ring pulse (i.e., after the DRON

report).
