If this is true then FORE will go to Nortel and Ascend will go to Lucent. I think BAY will also go to Nortel. You may be right about these, but a case could be made for the above sentence also, if Nortel was switched with Lucent in each instance. By "switch product", I take it you mean the ability to do SVC's, right? I believe the crossbar is used in Yurie's product. Crossbar switching is a pretty straight-forward and easily-implemented technology. What I mean is that the Yurie product is not a switch. There is no switch fabric (crossbar). It does not have the ability to take any input and move the data to any output. It is a concentrator. It takes various legacy type interfaces in, ie, T1/E1/DS0/DS1/frame/etc, and adapts this traffic to an ATM output. Conversely, it could take that same associated ATM input and adapts it into its corresponding component output (T1/E1/etc.). Each traffic stream might occupy a PVC or (if voice is involved) SVC in the ATM stream. These legacy types of ports also exist on a multiservice ATM switch. However, depending on the amount of the legacy traffic involved, it can be much more cost effective to put one of these Yurie boxes (or ASND SA box) in front of an ATM switch port on say a 500 or 550 box and concentrate the traffic before it enters the switch.
