Is that the 253B shelf?  Wire-wrap is not really the problem.  The real 
problem is availability (though size is also a consideration).  I just 
looked through the Tellabs equipment on ebay and don't see any of the 8-slot 
shelves available right now.

Either way, it doesn't solve my problem.  If I am installing asterisk in a 
small to medium sized office, I would like to find a product that is easy to 
purchase and easy to connect.  I don't want to rely on something that I 
*might* be able to get if I watch ebay close enough, never knowing just how 
much space it needs, how much I will have to pay for it, or if it will 
actually work when it arrives.

I didn't really mean to be short in the last email, but it seems (IMHO) that 
there is a huge need for a current product like this.  Evidently they *do* 
exist, at least according to the Ditech and Valient websites, but I can't 
seem to find anyone that actually sells them.  My hope was that some of the 
other integrators or suppliers on this list might have found a current 
product that fills this need.  Is everyone just using the ancient Tellabs 
stuff?
