Optimize T1 access facilities and maximize Class 5 switch port capacity

In today's competitive telecommunications environment, extending capital budgets and lowering operating costs are often the keys to survival. The Access Navigator ® /GR-303 + Data Host can help carriers utilize existing resources more efficiently – slashing recurring T1 backhaul costs and reducing the required number of Class 5 switch ports. It also allows carriers to provide service to a greater number of customers without additional infrastructure investment.

The Access Navigator combines Telcordia™ compliant GR-303 oversubscription with a 1/0 Digital Cross-connect System (DCS) for grooming and concentrating voice and data traffic. GR-303 allows the service provider to oversubscribe T1 backhaul voice circuits by as much as 16:1 without losing GR-303 trunk redundancy. Using the 1/0 cross-connect capabilities, the service provider can efficiently groom multiple fractional T1s into fully utilized T1s, resulting in as much as 8:1 savings in T1 backhaul links. These two features combined allow the service provider to maximize utilization of T1 backhaul facilities; free unused bandwidth in fractional T1 links to service new/additional customers; and oversubscribe voice circuits to reduce the demand on Class 5 switch port capacity.

With its small footprint and low power requirements, the Access Navigator can be used in applications where traditional large, expensive DCS platforms would be impractical. This opens up a wide range of applications from the network core, to the network edge, and into the customer premises.

The Access Navigator is designed to help service providers optimize their existing architectures and open additional revenue-generating opportunities, including:

• Reduction in recurring T1 backhaul expenses (remote to central office)
• T1 1/0 grooming for cell site daisy-chaining (wireless)
• GR-303 oversubscription of voice channels (central office)
• Class 5 switch port optimization (central office)
• DCS augmentation or replacement (central office)
• DLC T1/fractional T1 offload (remote)
• Maximized router port utilization (network)
• Cost and rack space constrained 1/0 cross-connect applications (collocations, POPs, CEVs)
