The base rate of an OC-3 would be 155Mbps. www.intelletrace.com
An OC12 circuit has the bandwidth of 622.08 Mbps. The OC12 is a product of the SONET standard for commercial bandwidth use. It is equivalent to having 336 T1 lines!
The data rate for an OC3 circuit is 155.52 Mbps. This is for a full port and not per line assigned from the connecting circuit. In other words, the full capacity.
OC3 bandwidth is 155.52 Mbps
An OC12 is equal to 4 OC3 bandwidth connections.
There are 3 DS3's in an OC3. Generally an OC3 or higher capacity circuit will be used to deliver a DS3 due to distance limitations of the DS3. http://www.intelletrace.com/internet-services/OC3-Internet-Services.html www.intelletrace.com Wholesale Internet for Business
A T1 is copper, and OC3 is fiber optic, so there is no way to make a T1 into OC3. Speed on a T1 is 1.544 Mbps, and speed on the OC3 is 155.52 Mbps, so in rounding, you need 100 T1 lines to equal the speed of an OC3.
An OC3 breaks down to three DS3's. A DS3 Breaks down to 28 T1's. Therefore there are 84 T1's on an OC3. If you go one step further there are 672 DS0's on a DS3 or 2016 DS0's on an OC3. a DS0 is a 64k Channel equal to a single POTS line. http://techblog.intelletrace.com/what-is-a-ds3-hub/

The rate that an OC3 can move data is at 155Mbps. For more answers go to. http://www.intelletrace.com/internet-services/OC3-Internet-Services.html
How much bandwidth required for e-gov application?
There is no information available as to how much bandwidth Essex FM online radio takes. It is not as much as required, but how much it takes up is what the worry is for. Most internet providers have a limit as to how much bandwidth you are allowed to use in a month.
The function of a bandwidth router is to moniter all the connections that are to do with the router and helps you work out how much bandwidth each connection is using.
A simple search of the net will find there are many bandwidth monitoring sites that are available for free. A popular one is callled Free Meter Bandwidth Meter. You also can use WFilter freeware for network bandwidth monitoring.
