+PMHR none
Initiate Modem on Hold: This command requests the DCE to initiate or to confirm
a modem on hold procedure. The DCE shall return ERROR if Modem on Hold is not
enabled or if the DCE is in an idle condition. The DCE shall return the string re-
sponse +PMHR: <value> where <value> is a decimal value corresponding to the
Modem on Hold timer value received or the request status during the DCE’s modem
on hold exchange procedure as defined below. This response may be delayed de-
pending upon the context under which the +PMHR command is made, i.e., if the
+PMHR is in response to an incoming Modem on Hold or if it is initiating a request.
m = 0 V.92 Modem on Hold Request Deniedor not available
m = 1 MOH with 10 second timeout Granted
m = 2 MOH with 20 second timeout Granted
m = 3 MOH with 30 second timeout Granted
m = 4 MOH with 40 second timeout Granted
m = 5 MOH with 1 minute timeout Granted
m = 6 MOH with 2 minute timeout Granted
m = 7 MOH with 3 minute timeout Granted
m = 8 MOH with 4 minute timeout Granted
m = 9 MOH with 6 minute timeout Granted
m = 10 MOH with 8 minute timeout Granted
m = 11 MOH with 12 minute timeout Granted
m = 12 MOH with 16 minute timeout Granted
m = 13 MOH with indefinite timeout Granted
Implementation of this parameter is mandatory if V.92 is implemented in the DCE.
+PIG=m 0
PCM Upstream Ignore: This command controls the use of PCM upstream in a V.92
DCE.
m = 0 Enable PCM upstream
m = 1 Disable PCM upstream
+PMHF none
V.92 Modem on Hold Hook Flash: This command causes the DCE to go on-hook
for a specified period of time, and then return on-hook. The specified period of time
is normally one-half second, but may be governed by national regulations. If this
command is initiated and the modem is not On Hold, ERROR is returned. This com-
mand applies only to V.92 Modem on Hold.
+PQC=M 0
V.92 Phase 1 and Phase 2 Control: This control controls the global enabling or dis-
abling of the V.92 shortened Phase 1 and Phase 2 startup procedures, not the initi-
ation thereof. This command is used in conjunction with the +PSS command.
m = 0 Enable Short Phase 1 and Short Phase 2
m = 1 Enable Short Phase 1
m = 2 Enable Short Phase 2
m = 3 Disable short Phase 1 and Short Phase 2
