Enable modem connections (PPP) via serial port/modem:
select
Enabled
.

Baud rate to use (effects connection between us and the modem only):
select
115200
.
h
Init string:
leave as
ATE0S0=1&K3
(see below).
The baud rate dictates the connection speed between the
CTIP-01
’s serial port and the modem, and does
not affect the connection speed between the local and remote modems, as they will negotiate their own
connection speed when a connection is made. It is highly recommended that this setting be left at the default
for best performance.
The init string is the command (using the standardized Hayes AT command set) that the
CTIP-01
will send to
the modem to activate it. The string included should work with the majority of modems and configures the
following connection properties: answer incoming calls on the first ring, enable hardware flow control, and
lock the connection speed. Your modem’s documentation will describe other potential init strings that you
can use to alter the connection properties. For instance, you could commit the settings to the modem’s
non-volatile memory (NVRAM) or allow the modem to adjust the connection speed for greater stability (and
so on). You may wish to test the connection with the default init string first before making changes specific to
your modem model or situation to simplify the troubleshooting process.

Configuring the Remote Connection
This section describes how to configure a typical Windows dial-up session to access the modem connection
on the
CTIP-01
. The instructions here relate to a
Windows XP
configuration; other versions of Windows are
similar.
Step 1
. Open
My Network Places
from the desktop or the
Start
menu.
Step 2
. Click
View network connections
.
Step 3
. Click
Create a new connection
under
Network Tasks
.
Step 4
. The
New Connection Wizard
window will open. Click
Next
.
Step 5
. Select
Connect to the Internet
and click
Next
.
Step 6
. Select
Set up my connection manually
and click
Next
.
Step 7
. Select
Connect using a dial-up modem
and click
Next
.
Step 8
. In the space provided under
ISP Name
, type an appropriate name of your choosing for the
connection. Click
Next
.
Step 9
. In the space provided under
Phone Number
enter the phone number for the line to which the
CTIP-01
’s modem is connected. You may need to add the area code, country code, or other
digits needed to access the outside line as appropriate. When finished, click
Next
.
Step 10
. Make your choice from
Anyone’s use
or
My use only
and click
Next
.
Step 11
. Beside
User name
enter the user name of any valid user created using the Web interface of
the
CTIP-01
. Beside
Password
and
Confirm password
enter the password that the user you
entered above uses to access the Web interface.
Step 12
. This screen also includes 3 checkboxes.
Uncheck all 3 checkboxes
.
Step 13
. Click
Next
.
Step 14
. You may select to add a shortcut to the desktop for this connection.
Step 15
. Click
Finish
.
You can now use this connection to access the
CTIP-01
modem. Since you will still login to the unit through
the Web interface after establishing a dial-up connection, the user name on the PPP connection and the user
name used to access the Web interface do not have to be the same. For security purposes, you may wish to
create a separate user name for dial-up access.
The unit will negotiate a PPP connection based on the settings you provided, and no additional scripting or
configuration should be required under most circumstances. This is a summary of the settings for use with
non-Windows operating systems, or other versions of Windows besides XP:
