Check those errors after it's been up a while - it could be that a lot occurred during the sync negotiation and you gave no indication of the previous uptime when the count was very high.
Some routers - e,g. Speedtouch/Thomson/Technicolor certainly had a propensity to report huge numbers of FEC errors - I've no idea if the numbers were correct or not but they seemed to have no impact on performance when I had one.
Here is a thread showing some monster counts further down from a Speedtouch - http://forums.thinkbroadband.com/dslrouter/3100583-s...
