leased Lines

Hi!

I have heard that when ever any company wants to get a Leased Line
then they ask for Compression ration
i.e they need 1 to 3 compression
or 1 to 4 or 1 to 8
what does this mean
which is more preferable
and which is cheaper
Reply with complete details
Thanks

leased Lines

by Barry Hensley In reply to leased Lines

When you purchase a leased line, you are simply purchasing a pair of copper wires from you local Telco. They don't configure the line for any particular compression, etc.

You will need to select equipment for each end of the leased line. This equipment must support the type of line (frame-relay, PPP, switched 56, etc), the type of service (data, voice, etc), and the QoS that you need. For instance, if you have a mission critical application that must have a certain amount of bandwidth, thenyour equipment must be smart enough to allocate a portion of the total bandwidth for this application. Also, if you are doing voice, then you are likely to break your leased line into channels that are dedicated to voice, leaving some channels for data.

A lease line is typically delivered in a group of channels representing either 56Kbs or 64Kbps capacity per channel. If you select a full T1, you are leasing 24 channels at 64Kbps per channel. Channels are grouped together to provide bandwidth for certain applications. You can group them all as one if you only have a single application (like data).

If you compress the data, you can send more data across the wire than what the circuit is designed to carry. For instance, a T1 will carry 1.544Mbps of data. If you compress 4:1 on each end, you can effectively get 6Mbps throughput on your T1. Compression allows you to gain more bandwidth without paying for a bigger pipe.

Yes I agree to the first answer but I would like to add that u may get a bit slower speed because of the overheads added for compression
