The Access Navigator/GR-303 includes GR-303 to TR-08 translation to allow simple migration from
older AT&T SLC-96® type digital loop carrier systems with TR-08 interfaces to newer systems with
GR-303 interfaces (see Figure 10-2). In addition, the Access Navigator can perform GR-303 call
concentration and DCS grooming for data services.
