Calix C7 DSLAM
The picture shown in this thread is an outdoor cabinet. It is NOT a DSLAM.
It is used to hold rack mounted equipment such as a channel bank.
You would have to be able to look inside to determine what it contains.
Here is a picture of a DSLAM that could
be mounted into an outdoor cabinet.
As you can see, it is intended to be rack mounted and is not weatherproof, so it needs to me mounted in an environmental cabinet.
Just because you see an outdoor cabinet does not mean you can jump up and down waiting for the speed increase.
