An analog adapter also known as an analog telephone adapter (ATA) is a small device that converts an analog signal into digital signal. In this case it is an analog telephone signal into a digital telephone signal (VoIP).
An analog adapter lets you use an analog telephone on a VoIP network because it has one or more FXS ports that you plug an analog phone into and one or more Ethernet ports that connect to a data network. Because VoIP runs over a data network, the analog adapter connects (adapts) the analog signal from an analog phone to VoIP which runs over the data network.
What is the difference between a locked and an unlocked adapter?
A locked adapter is an adapter where the software has been locked to a specific service provider. If you buy locked adapter you can only use it with the service provider that the software has been locked to. Vonage for instance locks the Linksys PAP2 to their service, if you buy a PAP2 from Vonage it will be very hard if not impossible to use it with a different provider.
An unlocked adapter is not locked to any service provider and can be used with any provider that supports the adapter. This does not mean that it will work with every provider, only that the adapter has not been locked to a specific service provider. It is always a good idea to call a service provider before signing up with them to see if they support the adapter you want to use.
*Voiplink only sells unlocked adapters
How do I tell the difference between a locked and an unlocked adapter?
With Linksys this is pretty easy, on the packaging if the model number above the barcode has an -NA then it is unlocked. As shown in the picture below, there are several places on the packaging that show the model number, but only the one above the barcode will have the "-NA" if it is unlocked.
This difference between locked and unlocked adapters has caused some of confusion for people, hopefully this article clears it up. If you still have more questions please contact a customer service representative at 866-987-8647.
What analog adapters does Linksys sell?
Linksys currently sells four different analog adapters and the main difference between them is how many and what kind of ports they have.
The base model is the SPA1001, which includes a single FXS port for connecting an analog telephone and a single Ethernet port for connecting to a data network. Like all Linksys adapters, the SPA1001 uses the SIP protocol and has all of the basic telephony features you would expect like call waiting, caller ID, caller ID blocking, call transfer and more. For more information please visit our SPA1001 product home page here.
The Linksys SPA2002 has been renamed by Linksys to the ï¿½Linksys PAP2ï¿½ see below for more information.
The Linksys PAP2 (formerly SPA2002) is one step up from the SPA1001 in that it has two FXS ports to connect analog phones to. So instead of connecting one analog phone as with the SPA1001 you can connect two. The Linksys PAP2 has been revised to the Linksys PAP2T and most if not all PAP2ï¿½s shipped will now be the PAP2T.
Like all Linksys adapters, the Linksys PAP2 uses the SIP protocol and has all of the basic telephony features you would expect like call waiting, caller ID, caller ID blocking, call transfer and more. For more information please visit our Linksys PAP2 product home page here.
The Linksys PAP2T is the most recent revision of the PAP2, it has twice as much memory as the PAP2 which makes the device very stable and it also supports two G.729 concurrent calls. The PAP2T has the same port configuration of the PAP2 and SPA2002 (two FXS ports and a single Ethernet port).
The Linksys SPA2100 is similar to the Linksys PAP2, in that it has two FXS ports for connecting two analog phones. But it also includes an extra Ethernet port and a built in router. The two Ethernet ports - one for the internal network (LAN) and one for the external network (WAN) allows you to put the device on the edge of the network or section it off from other devices so they do not interfere with telephone calls. This is handy if you have a lot of other devices on your data network or you do not have a data network at all, because the SPA2100 will create its own network or a sub network inside of your existing network.
The SPA2100 does require more technical knowledge than the previous adapters, but if you find you need its extra functionalities it might be worth learning more about data networking.
The SPA2100 has been revised, the new model number is the SPA2102. Most if not all SPA2100's shipped will now be the SPA2102.
The Linksys SPA2102 has the same port and router configuration as the SPA2100 but it has more memory and the Ethernet ports have been upgraded from 10Mbits to 100Mbits. This provides more bandwidth for the device which is useful especially if other devices are using it as the gateway. The router functionality of the SPA2102 is the same as the SPA2100, so it provides the same benefits as the SPA2100 for separating or creating networks.
The Linksys SPA3000 is a very popular model because it includes an FXS port and an FXO port. The FXS port allows you to connect a standard analog telephone like all the other adapters but the FXO port allows you to connect an incoming analog telephone line to the adapter. This is useful if you want to have a fail over connection incase something goes wrong with your internet connect or VoIP provider. If something does happen, you will have a back up line that will use a standard telephone connection to connect through.
The SPA3000 has been officially discontinued by Linksys, but at the time of this writing (01-09-07) they can still be found in the distribution channel. The replacement model of the SPA3000 is the SPA3102 (described below), orders for the SPA3000 may be shipped the SPA3000 or the SPA3102.
The Linksys SPA3102 is the replacement model for the SPA3000. The SPA3102 is similar to the SPA3000 except that it has a built in router and extra memory for storage. It has one FXS port for connecting to analog telephones, one FXO port for a failover analog connection, and two Ethernet ports. The two Ethernet ports ï¿½ one for the internal network (LAN) and one for the external network (WAN) allows you to put the device on the edge of the network or section it off from other devices so they do not interfere with telephone calls. This is handy if you have a lot of other devices on your data network or you do not have a data network at all, because the SPA3102 will create its own network or a sub network inside of your existing network.
