The Access Navigator provides all the grooming and filling functions of a 1/0 digital crossconnect system
(DCS) to maximize T1 usage. With carrier/customer demarcation testing, carriers are able to decrease
maintenance costs and labor, while increasing service availability. Fractional voice and data services from
multiple customers and applications are combined by the Access Navigator to save recurring backhaul
transmission costs, and capital costs on switch or router ports.
