I can tell you that most carriers have neither type, at least in the US.
Most towers can survive a brown/blackout lasting a few minutes (usually enough to last the safety system cycling and the fuses blowing on a grounded leg). Major towers tend to have 8-12h of battery, with sometimes 24h. Most utility outages are restored in that time with the exception being major storms. In michigan we can get a credit for lack of restoration in 16 hours: -- snip -- A customer is eligible for a credit under normal conditions if the utility fails to restore service within 16 hours after an outage resulting from conditions other than catastrophic conditions. -- snip -- this lines up with the planning strategy of the utilities. - Jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
