Well, do be careful.

Most carries have "performance objectives" which they adhere to,
and they specify some number of errored seconds per day per circuit,
and those numbers may vary based on route-milage.

Unfortunately I think most of those numbers are covered under NDAs,
but I can safely say that 1 errored second/day would be well
under the criteria and 1,000 would be well over, and anything in
between depends on your carrier and route miles, etc., etc.
