So basically a 1G connection to the switch, buffering with frame drop, 
and a tri-rate RJ45 connector? Sounds like something that could easily 
be built into our Chronos platform 
We'd just have to remove the SyncE, and add the 10/100 Mb support.

Probably the most complex part is to build a business case for it to 
pitch to our management. Would anyone be willing to email me a price 
indication, and perhaps an indication of how many of these products 
would be needed? No obligations of course; just to get an idea of 
whether a business case can be built?

Kind regards,
