Pineshn,

 

E1 and T1 are respectively the european and american standards for digital data transmission.

E1 bandwidht is at 2 Mbps (32 channels at 64Kbps) with two channels reserved for control and signalization.

T1 bandwidht is at 1.5 Mbps (24 channels at 64Kbps).

E1 and T1 lines may be interconnected for international use.

 

Concerning your question about the converter, yes of course it is possible to use a it but depending on how is the presentation of your cable, you can know which media converter at both ends of your fiber.

 

hope this helps

If you have the switches with GBICs you can eliminate need from media converters but there is no conn with T1 E1 lines the fiber media is used for more faster connections from 100Mbit/s to 10Gbit/s , T1 and E1 lines most used in conjunction with ISDN networks and Serial HDSL links.

In my opinion, Media converter is the best way to invest. if you compare the price of media converter and optic mux, you will see the big different. And media converter at 100Mbps can provide more bandwidth than E1 or T1. In your case, optical cable with media converter might be the best way to do.

 

From my experience,I found that most of E1 or T1 usage in for interconnecting to the traditional circuit switch of telecommunication industry such as PSTN, ISDN.

Media converter is just fine in case there is a dark fiber to be rented. I am in doubt that author has an dark fiber, he says bandwidth. And if he asks, what is E1 - that means that provider is giving them just a E1 over the the fiber using. the muxes.

Now, to get Ethernet connection over the E1, he can use for example any of those inverse muxes or converters:

I suggest you read the FAQs before posting, live links are not allowed on the boards.
