Diverse carrier entrances
Two carriers are not physically diverse when their routes converge in the same trench, building entrance, riser or room.
How it works
Trace each service from an external route through separate entrance facilities and pathways to its intended termination.
Where it fits
Sites whose service objective depends on surviving a localized carrier or pathway event.
Where it breaks
Commercial provider names are being used as evidence of physical route independence.
Tradeoff register
- Reduces localized route exposure
- Requires outside-plant evidence
- Diversity can be lost during later carrier changes
