Diversity

Supporting businesses with critical operations, such as banking, requires strategies for predictable recovery, not only from regular network faults, but also from attacks on signaling networks. When planning to move to an SS7-over-IP network, the operator should consider equipment and connection diversity to assist in recovery.

The range of diversity will differ from customer to customer and it may include a multitude of factors:

• Entry diversity offers more than one cable entrance into a building
• Pair and cable diversity provides a local loop connection through multiple, nonadjacent pairs in more than one cable
• Path or route diversity provides end-to-end, physically or logically separate routes for a circuit
• Central office diversity provides local loops that terminate in more than one central office
• Site diversity provides alternative or backup locations
