- When you mix non-link integrity (pre 10BaseT) with 10BaseT
- standard you get massive collisions. I run both the old
- and new side by side by cascading hubs with an AT&T transceiver
- that has a switch for link-integrity - they work fine together.
- Some hubs (Asante, AT&T) have link-integrity switches on a per-port
- basis. And the newer StarLAN10 cards have a link switch on back.
