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.
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.
|On: A test is active
Off: A test is inactive
|On: A new alarm is detected in the alarm buffer
Off: No alarm currently detected

FUN Stuff – Accessing the Config
FOLLOW THE BELOW AT YOUR OWN RISK!!! – I TAKE NO RESPONSIBILITY!!
THE BELOW IS FOR INFORMATIONAL EDUCATIONAL PURPOSES ONLY!!
Now that we know what the RAD box is and does. Lets see if we can have some fun with it.
If you have had an EFM service installed by TTB then, you should be able to access the config on the RAD box. You simply need a USB to Serial adaptor.
Open Hyper terminal or putty and use the rate of 9600 on your com port, open the connection, then press enter a few times. you should see a prompt like the below:
Loading ... Decompressing to RAM. Processing archive: FLASH Extracting LA_210.BIN ................................................................................................................................................................................................... CRC OK Running ... ******************************************************************* * In order to start working - press the ENTER button for few times* user>
Enter the user name “su” and password “1234”
user>su password>**** TEST#
if you type “info detail“, you will see the whole config of the RAD unit.
if you have a spare one or ha accuired it from someplease, then you can reconfigure it.
below i have listed a very simple config that you can copy and paste in to a factory reset unit.
to factory reset the box type “admin” <Prese enter> type “factory reset”
this shows you the simple syntax the RAD box uses and configures it with some simple test stuff
configure router 1 interface 1 address 192.168.1.125/24 management-access no shutdown exit default-gateway address 192.168.1.1 exit management manager 192.168.1.10 exit user su password password user oper password password user tech password password user user password password exit system date-and-time sntp server 1 address 184.108.40.206 zone gmt exit exit system name TEST contact "Bob The Builder" location "My Comms Room" exit exit all save save
