Depends on the provider. I'm sure you can get some type of SLA from the providers.

>What are the function of services like E-Line and E-Lan

E-Line would be an alternative to a point-to-point service such as a T-1 line.

E-LAN would be an alternative to a multipoint service such as Frame-Relay.

Do you mean "guaranteed data rate"??? If so then basically, yes. You have 1.5mbps of bandwidth.

>In Cable networks i think this doesnt happen!

For most consumers of cable internet access, this is true. There are no guaranteed data rates. But that doesn't mean it can't be done. It's just that most consumers of home cable internet access products aren't interested in the cost of a guaranteed data rate.

Right. Cable providers offer things like guaranteed bandwidth, uptime, minimal outages, etc. An SLA.

You contact your provider and ask what they have to offer.

Oh...

It's just a matter of QOS (or more specifically,  rate limiting). Of course, this assumes that you haven't oversubscribed the service. :-)

So for instance, for instance in ADSL i can have contention rates of 1:1 , with metro ethernet over docsis i can achieve certain a performance assured line by implementing QoS live CIR CBS etc ?

You could implement on any of the equipment that supports it (that you have control over).

Not to be anal, but it's almost all copper. ATM, T1, DSL, Cable.

Now if you mean specifically DSL...

DSL is distance limited. ~14,000 feet. And once you're out to distance, the bandwidth degrades. Someone that's 2,000' from the CO may get 8mbps while someone that's 12,000' can only get 1mbps. DSL bandwidth maxes out around 10mbps.

ME will work at whatever the max media rate is (100mbps is not unheard of) and will operate at max speed at whatever the working distance is.
