Hi all,

We have a customer who would like to upgrade their IPK to a PRI. There are two different PRI cards available PRT-1-U10 and PRT-1-U20. Does anybody know the difference between these two cards?

I believe the U-10 could not do E&M wink signalling. It was an early release with some limitations. Especially with regard to CID and CO protocol (ni-2). You are better off going with the U-20.
