[c-nsp] Frame PVC -> 802.1q VLAN

[Matthew Crocker]

Seranoa had a product which did that (Frame Relay Frames -> dot1q  
VLAN tagging) called the WANPort.   Their techology was purchased by  
Whiterock (www.whiterock.com) and is now sold as the VLX300 &  
VLX400.   I have one of the old Seranoa boxes,  works great, too bad  
they never survived.  It can do FR-PVC, PPP, MLPP, HDLC framing to  
802.1q,  terminate an OC-12 worth of DS-1s into 336 vlans on a GigE  
trunk going to a router.
