Introduction
This guide provides all the information you need to use
your Cable Modem TMX and an analog modem to dial into
one-way Broadband Service Providers (BSPs).
Not all cable companies and BSPs provide two-way service.
In the event that you have a one-way cable provider or BSP,
you need to use an analog modem to send data to the
provider, and then receive data from the provider over the
cable line using a cable modem like the TMX.
BSPs who currently offer one-way service may choose to
upgrade to two-way service at some point in the future.
Your new Cable Modem TMX is software upgradable to
the full operation of the 3Com
®
U.S. Robotics
®
Cable
Modem CMX. See the chapter in this guide about two-way
access for more information.
If you purchased the TMX Dialup Kit, the external analog
modem required for dialing into your provider is included.
If you purchased the TMX modem alone, you will need a
compatible external serial analog modem. (This product
will not work with an internal or USB-only analog modem.)
The diagrams and instructions in this guide assume you
have purchased the Dialup Kit.
Installation using a modem other than the one included in
the Dialup Kit should be very similar to the procedures
described in this guide. Consult your analog modem's
documentation for more details concerning its operation
and setup.
