When we setup an EFM connection we install an EtherAccess LA-210 unit on your premises. This is referred to as the Network Termination Equipment (NTE) or occasionally the RAD box.
The purpose of the NTE is to 'bond' the multiple lines that are used on an EFM connection into one line. There are Ethernet ports on the rear of the NTE that allow you to plug your own equipment (such as a router) in.
It's important to realise that the LA-210 is not a router, and it is up to you to either configure your network to use the EFM connection, or purchase the optional Technicolor TG672 router from Gradwell. For more information please see this article.
Rear of the LA-210
The LA-210 provides four RJ-45 ethernet ports that the you can plug your own equipment into. These are on the far right of the picture below.
The two RJ-45 ports to the left are intended to accept the bonded copper lines. You should not need to touch these, and no other equipment should be plugged in here.
Front of the LA-210
The front of the LA-210 includes LED lights that can indicate the state of the unit and the connection.
Please note when reading the table below that the indicated status of the WAN light will vary depending on whether your EFM circuit is a two-pair or four-pair installation.
