The overwhelming majority of telephone connections in the world are based on POTS. If
you have a "normal" or analog telephone in your home, HM220dp is the right modem for
you. On the other hand, if you have an ISDN or digital phone, you will need HM220di. If
you are not sure which version is the right one for you, please contact your service
provider.
The modem sends and receives very high-speed signals via the regular telephone
network, using Discrete Multi-tone (DMT) Digital Subscriber Line (DSL) transmission.
HM220d utilizes the expanded capacity of ADSL-ready telephone lines to handle
Internet and multimedia data, while allowing you to make and receive phone calls on the
same line.
When installing the HM220d ADSL modem, you have the option of connecting it to your
computer with either a USB connection (if supported by your computer) or an Ethernet
connection. The plug-and-play aspect of USB simplifies installation, requiring only a
cable plug-in and the installation of a driver (supplied on the CD-ROM). An Ethernet
connection, which requires that a Network Interface Card (NIC) be installed on your
computer, allows you to connect multiple computers to a single modem.
Once you are connected, a simple press of the PipeLock button (located on top of the
modem) guarantees the security of your computer. When PipeLock is activated, the
modem remains logged on to the network, but direct communication between your
computer and the outside world is blocked. This prevents outsiders from gaining access to
any information on your computer, even when you are not there. To resume Internet
access, simply press the PipeLock button again.
Time and technological development never stand still. Ericsson will keep you updated
with the latest technology, and let you download the latest software update.
