COURIER HIGH SPEED MODEMS
in mind that you can use the switch and, if the remote user does
not have a switch, he or she can follow the instructions for using
-
-
the appropriate AT command. -
Voice/Data 8witch-832= 1, 832=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, 532= 1. The Answer modem should have 532 set to 2.
NOTE: 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 532 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 (532=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.
