Do telcos in the US actually book contention ratio's on protection paths?! After thinking about it, it makes sense. Why else do seemingly minor fibre breaks cause so much disaster [hello Sean!] At COLT on our Metro SDH provided services if we say that its protected then its never overbooked, we do offer unprotected services to carriers. On Gemini and AC-1 they have protected paths, Gemini being the slightly better cable as according to the brochure I have AC-1's US leg comes into the same location [brookhaven?]. Regards, Neil.
