How Do I Subscribe to High-Speed Internet and Telephone
Service?
Before you can use your residential gateway, you need to have a high-speed Internet
access account. If you do not have a high-speed Internet access account, you need to
set up an account with your local service provider. Choose one of the options in this
section.
I Do Not Have a High-Speed Internet Access Account
If you do
not
have a high-speed Internet access account, your service provider will
set up your account and become your Internet Service Provider (ISP). Internet access
enables you to send and receive e-mail, access the World Wide Web, and receive
other Internet services.
You will need to give your service provider the following information:
The serial number of the modem
The Media Access Control (MAC) address of the modem (CM MAC)
Other MAC address numbers as needed
These numbers appear on a bar code label located on the residential gateway. The
serial number consists of a series of alphanumeric characters preceded by
S/N
. The
MAC address consists of a series of alphanumeric characters preceded by
CM MAC
.
The following illustration shows a sample bar code label.

How Do I Subscribe to High-Speed Internet and Telephone Service?
I Already Have an Existing High-Speed Internet Access Account
If you have an existing high-speed Internet access account, you must give your
service provider the serial number and the MAC address of the residential gateway.
Refer to the serial number and MAC address information listed previously in this
section.
I Want to Use the Application Server for Telephone Service
You will also need to set up a telephone account with your local service provider to
use your residential gateway for telephone service. When you contact your service
provider, you may be able to transfer your existing telephone numbers, or your cable
telephony service provider will assign a new telephone number for each current or
additional active telephone line. Discuss these options with your telephony service
provider.
