DSLAM Basics

Jah bless u ranger.. i feel updated and still reading...

its great to learn here

please neatly explain what is dslam in brief

Hi Tech Savvy,

This thread should have given you a good idea of what a DSLAM is but here is more:

1) DSLAM is piece of equipement designed to supply multiple Digital Subscriber Lines (DSL) to customers and providing those lines with connectivity to an ISP for WWW.

2) DSLAMs are normally housed in a chassis within an equipment rack, and consist of a number of cards, or plug in units. These typically are a CPU card, DSL interface cards and Gigabit ethernet cards (for ISP connection).

Hope this helps. If not start at page 1, make a list of questions, and next time I am passing I'll try to help.

Hi Ranger!

We setup a DSL setup in which we have Paradyne IP DSLAMs terminating via E1s to BRAS (Cisco VXR 7206 Box) .Now i've created one vlan per subscriber on dslams to segregate the traffic of different users but the problem is that when one subscriber is already transmitting traffic on say vlan 1 the other subscriber cant even connect to the dslam say on vlan 2 . Now i try putting all the subscribers on the same vlan then simultanous communication begins flawlessly. Tell me whts the reason of failure of simultanous transmission from different users having different vlans?
Do i have to create subinterfaces on BRAS (cisco 7206) having each subscriber to terminate at different subinterface? But we dunt want inter-vlan routing .Wht to do now...
Help will b appreciated.
