E Link - Extended Link

An extended link connects an SP (Signalling Point) to an alternate STP (Signalling Transfer Point). E links provide an alternate signalling path if an SP home STP cannot be reached via an A link. E links are not usually provisioned unless the benefit of a marginally higher degree of reliability justifies the added expense.
