The RAD LA-210 EFM SHDSL Box

Overview and description (Commonly Used By TalkTalk Business EFM)

When you order an EFM connection you are sent an RAD EtherAccess LA-210 unit to be installed on your premises. This is referred to as the Network Termination Equipment (NTE) or occasionally the RAD box.rad efm 3

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 router.

Because this RAD Box bonds 2 wire telephone lines (up to a total of 4 lines or 8 wires) together the effect is that you get an Eithernet cable/network cable that you can then plug in to your own kit

Some providers then have there own routers like Cisco, ZyXEL, and junipers connected to this box and can offer a whole range of services like VoIP, Data, CCTV etc.

Some providers also route your traffic directly in to there data centers, creating a private connection between you and the data center. This is usful for centrally managing internet connections and access, or to enable you to have a central hosted VoIP PBX in the cloud and connect all your phones to it.

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.
