Relationship among the Devices
What the Modem Does
The Wireless Gateway provides high-speed Internet access as well as cost-effective fax/modem services
over residential, commercial, and education subscribers on public and private networks via an existing
CATV infrastructure. The IP traffic can transfer between the Wireless Gateway and EURO-DOCSIS
compliant head-end equipment. The data security secures upstream and downstream communications.
What the Modem Needs to Do Its Job
The Right Cable Company:
Make sure your local cable company provides data services that
use cable TV industry-standard EURO-DOCSIS compliant technology.
Contact Your Local Cable Company
You will need to contact your cable company to establish an Internet account before you can use your
gateway. You should have the following information ready (which you will find on the sticker on the
gateway):
The serial number
The model number
The Cable Modem (CM) Media Access Control (MAC) address
SSID, WEP/WPA-PSK information

Your cable company should always be consulted before installing a new cable outlet. Do not attempt any
rewiring without contacting your cable company first.
