Can I buy my own modem?

The Cable Industry has adopted a standard for cable modems called DOCSIS. There are many companies producing DOCSIS certified modems. Retailers are offering these standardized modems for sale. Nationwide, most cable systems are in the process of deploying the DOCSIS architecture. As a result, a DOCSIS modem bought for use in our system will have a strong likelihood of compatibility with other cable systems in the future.

The multiple computers share the same primary account (which includes a total of 5 users and 3 email addresses-one is assigned and non-changeable and the other 2 are user designated).

What about security on the system? How do I know that my credit card can not be stolen?

While security is a concern for many current Internet users, all data passing through the H.S.I. modem is encrypted. Any transaction conducted over the H.S.I. service will be equally secured to those handled over your existing service provider - H.S.I. is just a lot faster. We do advise our customers to use all common sense precautions when using credit cards for electronic commerce - just as you would with any other form of credit cards purchasing.

Can other H.S.I. users see the data I send and receive?

No. Every byte of data H.S.I. sends to its cable modems is encrypted with the widely-used DES encryption algorithm designed by the U.S. government.

Any data sent from your computer to the Internet is also encrypted, and none is ever sent to other H.S.I. cable modems in your neighborhood.

However, as with any Internet account, data sent from your computer could be intercepted once it leaves H.S.I. We always recommend that our customers take care when sending any sensitive information by e-mail, and always make sure that you are using a `secure' form to submit credit card information. Check your Web browser's documentation for more information about secure forms.
