Description

Carrier Access:GR-303 Access Navigator Platform Simple Type: Interface 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.
