3.2.8 AT- Commands
-SDR=n - Enable/Disable Distinctive Ring
This command enables or disables detection and reporting of distinctive ring. The syntax is AT-SDR=n, where n is a number
from 0 to 7. One, two, or three distinctive ring types can be simultaneously enabled depending upon the value of n (bit
mapped). The detected ring type is reported in the long form (verbose) of the result code by appending the ring type number
to the end of the RING message.
-SDR=0 Disables Distinctive Ring. Any valid ring detected is reported as RING (default).
-SDR=1 Enables Distinctive Ring Type 1.
-SDR=2 Enables Distinctive Ring Type 2.
-SDR=3 Enables Distinctive Ring Type 1 and 2.
-SDR=4 Enables Distinctive Ring Type 3.
-SDR=5 Enables Distinctive Ring Type 1 and 3.
-SDR=6 Enables Distinctive Ring Type 2 and 3.
-SDR=7 Enables Distinctive Ring Type 1, 2, and 3.
Result Codes:
OK n = 0 to 7.
ERROR Otherwise.
The n value bit map is:
Bit 0=1 Enable RING type 1. RING type 1 is detected and reported as RING1.
Bit 1=1 Enable RING type 2. RING type 2 is detected and reported as RING2.
Bit 2=1 Enable RING type 3. RING type 3 is detected and reported as RING3.
The ring types supported and the corresponding ring cadence detect criteria are:
