TransNexus Solutions

BroadRiver Communication Corp., a Competitive Local Exchange Carrier (CLEC) based in Atlanta, GA, has deployed the TransNexus least cost routing (LCR) solution. BroadRiver serves customers throughout the Southeastern US. Since 2002, BroadRiver has focused on providing technology and communications solutions to businesses. BroadRiver’s VoIP business has grown rapidly through internal growth and acquisition. Initially, BroadRiver built a Cisco based H.323 VoIP network designed for serving business customers.

In 2005, BroadRiver made the strategic decision to expand its VoIP business by providing VoIP services to cable customers. Serving cable customers required being able to register and control thousands of IP based Media Terminal Adapters (MTAs). To meet these new service demands, BroadRiver chose the MetaSwitch VP 3500 softswitch which provides a full range of Class 5 features with SIP and SS7 interoperability.

In addition to enabling VoIP services to retail subscribers, the MetaSwitch provided BroadRiver with the benefit of easy access to multiple inter-exchange carriers via SIP trunks. By least cost routing long distance traffic across multiple carriers using SIP, BroadRiver would able to decrease the cost of its long distance services by 40%.

However, implementing VoIP least cost routing (LCR) for the domestic US market is becoming increasing complex for several reasons. First, the number of interexchange carriers (IXCs) and CLECs offering direct SIP access is increasing. Second, partitioning of wire centers (NXXs) between up to ten different operating companies (OCNs) is rapidly increasing the size of the domestic US routing table. Third, in addition to rates for inter-state and intra-state calls, more carriers are offering special rates for extended local calling areas. More carriers, more routes and more rate plans add up to a least cost routing table with up to two million routes or more.

Softswitches and other VoIP signaling devices are not designed to for managing a dynamic least cost routing table with 500,000 or more routes. To solve this problem, BroadRiver used the least cost routing and billing solution offered by TransNexus, a MetaSwitch OSS/Network Management Partner. The TransNexus solution provides BroadRiver with a single intelligent routing solution for its MetaSwitch and its Cisco H.323 network.
