Common use of SES Physical Access Diversity Clause in Contracts

SES Physical Access Diversity. For Physical Access Diversity, NBI offers two options. Primary physical option and secondary physical option. SES physical access diversity enables the Service Provider to order a secondary diverse SES physical circuit between the End User NTU to a physical port on the active PoH. A Service Provider can switch traffic from the primary SES physical circuit to the secondary diverse SES physical circuit in the event of a fault occurring on the primary SES physical circuit. This provides Service Providers and their End Users with a level of access resilience on SES physical circuits. The physical access is delivered on a fibre cable from the NBI network to a Service Provider PoH. For Dual NTU/Single active PoH/Dual Fibre/Dual Duct, where the physical network can support it, two separate SES physical circuits are implemented between two NTUs located at the End User site to two physical ports on the same serving active PoH. Both SES circuits are active, and both fibre paths are located in separate ducts.
