Network Connectivity

Mission-critical call centers rely on a robust network infrastrure. The USAN network & switching architecture consists of systems arranged in a distributed model for the highest possible resiliency. Components in each node are installed in an N+1 configuration so that a single USP failure will not impact traffic capacity at the node. Nodes are viewed by the network as single virtual nodes and all ports are capable of supporting all applications. This shared infrastructure is supported by our soft-switch architecture that allows all applications full access to our state-of-the-art, call center feature set - there is no stranded investment if enterprises want to add or change functionality over time.

Carrier Management

USAN's network architecture is unique as its nodes are co-located in carrier facilities and interconnect with them on a carrier-to-carrier basis, thus giving us full access to all network signaling protocols.

VoIP/TDM

The USAN platform connects with both TDM and IP circuits as the network interface is independent from applications, thus any given application can receive inbound calls on TDM and IP - providing enterprises complete flexibility and expanded call center capabilities.

Switching/Routing

By leveraging USAN's fault-tolerant, scalable platform, enterprises can design virtually limitless options for how their calls are handled. Several popular functions include routing based on the time of day, day of week, holiday, geographic, number of attempts, secondary number dialing, alternative/contingency dialing, percent allocations, and take back and transfer (T&T).

SS7 Signaling

USAN uses SS7 connectivity to allow for faster call set-up times and more rapid diagnosis of troubles. Our platform supports TDM connections through SS7 (U.S. and European standards), any type of in-band feature protocol, and ISDN interfaces. The platform supports release link trunking (RLT) for call transfers and trunk group ID terminations where supported by the carrier.
