S-Parameters
Reading and Setting S-Parameters
Commands that begin with the letter “S” are called S-Parameters. The number following the “S”
indicates the parameter number. The Telephone Module can select an active S-Parameter and
(where applicable) perform read/write operations. Commands can be performed on an S-
Parameter as follows:
ATSn – Makes S-Parameter n active
ATSn=v – Sets S-Parameter n to value v
ATSn? – Reads current value of S-Parameter n
Once a register is made active (the last register accessed), the register name is optional and can
be omitted from subsequent read/write commands that reference the same register. This is show
in the table below.

ATS7
Make “S7” Parameter Active
AT=51 or ATS7=51
Set “S7” to 51 (decimal)
AT?
Read Value of “S7”
If the number n (or the value v on a write) is out of range or invalid, the module will return the
“ERROR” message. All S-Parameter values and responses are in decimal format. All S-Parameters
can be read using “&V” command [Table 3-03].
