EAD versus Leased Line

[Brave_heart]

Whats the difference between Leased Line and EAD?

Which one do i want?

What are the pitfalls?

 

thanks!

Strictly speaking EADs are leased lines, but I assume you mean internet links? An EAD is a private dedicated P2P Fibre link.

 

 

Ethernet Access Direct (EAD) is a point-to-point data service offering high bandwidth connectivity over a standard radial distance up to 25km between sites. This enables a secure link between a combination of end user sites. It is ideal to extend LAN infrastructure over the network, with standard Ethernet connectivity.

Thanks for this.

So why would i want EAD as opposed to a leased line for my Internet connectivity?

 

Is EAD really to benefit the phone system while not really giving create internet access?

An EAD wouldn't give you internet connectivity itself, unless you were connecting to another site which already had internet connectivity.

 

You want something like these for site internet access. (You aren't limited to just BT mind)

so, Leased line is better, more adaptable and has greater expandability.

if a company is trying to sell us EAD then it must be running back to their place for Inet connectivity?

Hi Braveheart,

 

as mentioned EAD, strictly speaking is a short p2p circuit, sold by openreach to communications providers (who then sell it on to their customers) It's one component. They don't provide Internet in their own right, just connectivity. But you will find that the term 'EAD' is often used as a general one for leased lines by some companies as this is the underlying technology. You wouldn't be able to buy a true EAD circuit yourself.

 

Terminology is quite a fluid thing! Leased line is also another general term that is often misused. Better to try to understand;

 

is the ISP/reseller reputable?

focussed on education

any reference customers?

Does the service provide Internet access?

what is the contention?

no usage limits?

fixed IP?

filtering included or extra? (what kind)

 

and of course, price and term,

 

If you'd like a price to compare (that fulfils the requirements above) let me know - I'd be happy to help,

 

regards

Hi @Brave_heart,

 

EAD's come in two flavours from BT Openreach and are sold to Communication providers and ISP's.

 

EAD stands for Ethernet Access Direct. EAD LA stands for Ethernet Access Direct Local Access.

 

EAD allows two sites to be connected together (up to around 25km in length max distance) with a 10Mbit, 100Mbit, 1Gbit or 10Gbit) capable interface installed at each end. You can then run IP over these circuits. We often use them if a secondary school has lots of local primary schools and wants to build a WAN.

 

an EAD LA circuit connects a site (e.g. a school) AND the local BT telephone exchange where an ISP will have their own LLU equipment. Nearly all BT Openreach based leased lines are configured using a EAD LA circuit. You can not use an EAD LA circuit for two sites where one isn't the BT local telephone exchange. For this you must use a full EAD.

 

So the answer to the question is what are you looking to achieve? If all its just Internet access then any ISP will probably offer an EAD LA circuit (we would) as part of the solution.

 

happy to have a chat with you if that'd help?

 

Thanks

 

Dave
