Re: [nsp] HSSI Card Limitations ?

Yes... Everybody uses them at 45mb/s for t3's, they work well.

There is no Cisco imposed limitation on frame-relay PVC's.

Some providers may impose a limitation, for instance Bell Atlantic
aka Verizon aka VADI won't set up public frame PVC's of more than
2mbit/sec on a t3, and while you can set up 4-6 of them and route
across the set, this is a diminishing returns games.

Other providers (uunet loves frame) will have other rules.
