Appendix A AT Commands
57
The <max_rate> specifies the highest connections rate for the DCE.
Valid <max_rate> Range:
0
Determined by modulation selected in <carrier> (default).
300—57333 Value limited by modulation selected in <carrier>.
Valid <max_rate> for each <carrier>:
V34
2400 bits/s—33600 bits/s in steps of 2400 bits/s.
V32bis 4800 bits/s—19200 bits/s in steps of 2400 bits/s.
V32 4800 bits/s—14400 bits/s in steps of 2400 bits/s.
V22bis 2400 bits/s.
V22 2200 bits/s.
V23C, Bell212A 1200 bits/s.
V.21, Bell103 300 bits/s.
+MSC=<src_v34>—Seamless Rate Change Enable
Use this command to enable or disable V.34 seamless rate changes.
+MSC=0 Disables V.34 seamless rate change.
+MSC=1 Enables V.34 seamless rate change (default).
+PCW=<call_waiting>—Call Waiting Enable
Use this command to select how the modem responds to a call waiting signal.
The soft modems response is also dependent on the current setting of the
caller ID command, +VCID.
Valid <call_waiting> Values:
0 Enable the call waiting detector. When a call waiting signal is
detected, toggle V.24 circuit 125 and collect caller ID as set by
+VCID (default).
1 Enable the call waiting detector. When a call waiting signal is
detected, hang up the current call.
2 Disable call waiting detector.
+PIG=<value>—PCM Upstream Ignore
Use this command to enable or disable PCM upstream in a V.92 connection.
+PIG=0 Enable PCM upstream.
+PIG=1 Disable PCM upstream (default).
