Routes and translates local and long-distance calls

The Access ExchangeTM combines the features of an intelligent CSU/DSU, Digital Cross-Connect Switch (DCS), channel bank, and call router in a single product.  Economical local and long distance services, DID (Direct Inward Dial) and high-speed data can be accessed without changes to customer telephone equipment. The Access Exchange optimizes the use of T1 circuits with its ability to route and translate local and long distance calls.  Typically located on the customer premises, Access Exchange terminates all voice and data services over one or two T1 lines and allows Interexchange Carriers (IXCs) or other service providers to offer local phone service without deploying local switches. The Access Exchange translates local phone numbers to 11 digit numbers so that a Class 4 switch can handle local numbers. The carrier can offer local phone service directly from these switches, and the subscriber can utilize the benefits of Automatic Route Selection without having to upgrade their PBX or key system. The IXC can then offer local services along with long distance, which maximizes the use of connections and increases revenue opportunities for the carrier.

Maximize Data and Voice Revenue

If the T1 is not fully utilized for local or long distance trunks, the Access Exchange can fill the balance of the T1 with data via the V.35 interface or second T1 interface. Legacy 56 Kbps data connections can be increased to high-speed 128 Kbps to 1.5 Mbps connections, while saving monthly access costs. The Access Exchange allows carriers to maximize revenue on one or two T1 access lines by packing the pipe with other communications.  Carriers or customers can manage the routing database from a centralized location via the Ethernet SNMP management port on the Access Exchange. Database changes to area codes or revenue generating services can be made from the NOC without trips to the site, minimizing disruption to the customer’s normal operations.
