Path Diversity

A term used to describe the capability of a system to route information through alternate or multiple network paths to assure reliability. An example of a system that uses alternate paths is a system with redundant gateways. ASTRO® 25 systems use redundant gateways at the zone core and, as an option, the design can also implement redundant site gateways at the subsystem level. Redundant site gateways, together with redundant transport paths (T1s), provide higher reliability than the single gateway and single T1 implementation.
