COURIER HIGH SPEED MODEMS
Voice/Data Switch⎯S32=1, S32=2
1.Phone the other user to establish the bit rate, parity, word length and number of Stop bits the other person's modem accepts. (Both modems should be offline, in Command mode.)
You and the other user must also agree on which modem will go off hook in Originate mode and which in Answer mode. The Courier is factory set to go off hook in Originate mode, S32=1. The Answer modem should have S32 set to 2.
NOTE: If the stored command string command has been used (&ZC=s), the modem will default to S32=9, which executes the stored command string when the voice/data switch is pushed.
Either party's device can be the originate or answer modem; it doesn't matter who made the phone call. But one modem must first enter Originate mode and the other then enter Answer mode.
2.Without hanging up the phone, press the voice/data switch.
If S32 is set to 2, Answer mode, press the voice/data switch immediately after the remote user forces the remote modem off hook in Originate mode.
3.The other party should force the remote modem off hook in Answer mode by pressing the switch.
If yours is the Answer modem (S32=2), the other party should press the voice/data switch immediately before you do so.
4.If the remote modem has handset exclusion, the remote user should also keep the phone off hook in order to switch back to voice later. If the remote modem doesn't have handset exclusion, you can try to switch back to voice later. Or, you both can hang up your phones as soon as the modems go off hook.
