0

0

Toggle V.24 Circuit 125 and collect Caller ID if enabled by +VCID

 

 

1

Hang up

 

 

2

Ignore V.92 call waiting

 

 

 

+PHSW=

 

This command causes the DCE to activate/de-activate the hook relay for supporting the 2C relay.

none

0

connects the telco terminals to the modem

m

 

1

connects the telco terminals to the phone terminals

 

 

 

 

 

 

 

PCM Upstream Ignore: This command controls the use of PCM upstream in a V.92 DCE.

+PIG=m

1

0

Enable PCM upstream

 

 

1

Disable PCM upstream

 

 

 

 

 

Modem on Hold Enable: This command controls whether or not modem on hold procedures are

+PMH=m

0

enabled during V.92 operation.

0

Enables V.92 modem on hold

 

 

 

 

1

Disables V.92 modem on hold

 

 

 

 

 

V.92 Modem on Hold Hook Flash: This command causes the DCE to go on-hook for a specified period

+PMHF

none

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 command applies only to V.92 Modem on Hold.

 

 

 

 

 

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 response +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 depending 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.

 

 

<value>
