Phone Adapter with Router

Welcome

Thank you for choosing the Phone Adapter with Router. This Phone Adapter will allow your computers to share a high-speed Internet connection as well as resources, including files and printers. And after you have set up your Internet phone service, also known as Voice over Internet Protocol (VoIP), you will be able to make phone or fax calls using the Internet.

How does the Phone Adapter do all of this? By connecting your computers and peripherals, including phones or fax machines, to the Phone Adapter and connecting the Phone Adapter to your cable or DSL modem, then the Phone Adapter can direct and control communications for your network. Each of the Phone Adapter’s two telephone jacks can operate independently, with separate phone service and phone numbers, so you can have up to two Internet phone lines per Adapter.

But what does all of this mean?

Networks are useful tools for sharing Internet access and computer resources. Multiple computers can share Internet access, so you don’t need more than one high-speed Internet connection. With Internet phone service, your Internet access can now be shared by your phones or fax machines as well. You will be able to make phone calls using the account you set up with your Internet Telephony Service Provider (ITSP), even while you’re surfing the Internet. Plus, you can access one printer from different computers and access data located on another computer’s hard drive. Networks are even used for playing multiplayer video games. So, networks not only are useful in homes and offices, but also can be fun.

PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is why the network is called “wired”.

network: a series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users.

lan (local area network): the computers and networking products that make up the network in your home or office.

ethernet: an IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium.

This focus on security makes the SPA2102 a reliable choice for businesses concerned about the confidentiality of their conversations.

The device is easy to configure and manage, thanks to its web-based interface. This allows administrators to quickly set up the adapter, manage network settings, and troubleshoot any issues that may arise.
