Hello,

We have a lab environment where we want to stream video over a dsl
network.  This is all in house and we have all of the equipment and
here's a basic diagram.  The problem we get is that the DSL line is
dropped whenver we try to stream video.  The size of the file is only
21k and it kills the connection back to the DSLAM.  The connection
between the DSLAM and the DSL modems is only 25 feet of cable, do you
think that this is the problem?  Do we need a 1000 foot cable to test?
 These are the problems.  Any help is appreciated.
