Chapter 1: Introduction
Welcome
Chapter 1: Introduction
Welcome
Thank you for choosing the Linksys Phone Adapter with 2 Ports for Voice-over-IP. This Phone Adapter will allow
you to make phone or fax calls using the your broadband connection.
How does the Phone Adapter do this? The Phone Adapter connects your phones or fax machines to your network
router or gateway, so telephone service is delivered through your cable or DSL Internet connection. Each of the
Phone Adapter’s two telephone jacks operates independently, with separate phone service and phone numbers,
so you can have up to two phone lines per Adapter.
But what does all of this mean? Networks are useful tools for sharing Internet access and computer resources.
With the Phone Adapter, your phones or fax machines can share your high-speed Internet connection and take
advantage of it. You will be able to make phone calls using the account you set up with your Internet phone
service provider, even while you’re surfing the Internet. So, networks not only are useful in homes and offices,
but also can be fun.
Use the instructions in the Quick Installation or this Installation and Troubleshooting Guide to help you connect
the Phone Adapter after you have set up an account with your Internet phone service provider. These instructions
should be all you need to get the most out of the Phone Adapter.
