Multiple E1's to Ethernet Converter

[forsudhaji]

Anybody has come across a converter which can take input as multiple E1's(say 2-many) and give output as Ethernet. Pls let me know..I am in need of that urgently..Pls let me know the Convertor name and vendore contact details.

What are you trying to do with it? There may be different products depending on what your objectives are.

For example, I know a product called an IPmux that will carry an E1 line over Ethernet, for example if you have two buildings connected by fibre, and you want to emulate an E1 line between then to carry your telephones. Details at http://www.tdmoip.com/Home/0,,5,00.html.

If, on the other hand, you want to use the E1 to link two sites, then Cisco will sell you any number of routers to do the job.

Please could you explain what you are trying to do.

This is what I need to do.......

I dont have enough serial ports in my Router to take E1's..But I have one FE port. My objective is taking 5 E1's from the exchange and put those 5 E1's in a convertor and take the o/p as Ethernet and terminate the same in My router's Eth port.

So I need to know if we have any E1's-Ethernet convertor. As I know RAD convertors which can do single E1-Eth conversion. But I need multiple E1's convertor.

It sounds like you are looking for a device called an "inverse multiplexer" or IMux. There are many for inverse multiplexing over ATM lines, but the following two models can use regular leased lines:

RAD Data Communications makes the IMX-4E1, which takes 4xE1 and bridges out to Ethernet.

Larscom 6000 Inverse Multiplexer takes up to 8xE1 on the WAN side and outputs to 10/100 Ethernet.

Remember, inverse multiplexers are used in pairs: you will need one unit at each end of your point-to-point E1 link.

So, if you need to connect two of your sites using multiple E1s, then this would be an easy solution for you.

If you are looking to for 5xE1 from an Internet Service Provider, it might be a little more difficult. You will need to negotiate with them to place one of your inverse multiplexers at their location. And they will need to connect it to one of their routers.
