Long Distance Application

Long distance networks handle all traffic outside of local calling areas, including international calls, wholesaling, 8XX calling services, calling cards and the transport of wireless-originated traffic. This high-volume, long-haul network requires the highest level of scalability and performance, as well as, sophisticated algorithms for cost-effective routing. The long distance market also has the most competitive pricing, so carriers must look closely for ways to reduce costs and increase revenue.

Sonus Networks advanced, next generation, packet-voice solutions suit the long distance market perfectly. The Sonus IP Multimedia Subsystem (IMS) architecture combines robust routing and service selection capabilities, with unparalleled scalability and performance. This significantly reduces costs, while increasing your revenue opportunities by offering comprehensive services, such as global voice Virtual Private Networks (VPNs). The Sonus IMS architecture also delivers carrier-class reliability over a packet voice architecture that is geographically insensitive. Sonus components can be centralized or globally distributed, and share enhanced services, such as prepaid calling.

The IMS architecture has integrated international gateway capabilities, providing seamless global expansion without excess equipment. These capabilities include automatic A-law to µ-law conversions, signaling conversions, nature of address conversions, code manipulations, and other features. Flexible dial and tone plans are easily configurable for any country, and network timing can be based on BITS, SETS or loop timing. Sonus supports interworking between a large, growing list of ISDN and SS7 variants, and provides TDM connectivity by E1, STM-0, STM-1, T1, T3 and OC3. This flexibility ensures your long distance solution can easily meet your global connectivity needs.
