TransNexus Solution Example for CLECs BroadRiver Communication Corp. is a Competitive Local Exchange Carrier (CLEC) based in Atlanta, GA serving 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 an H.323 VoIP network designed for serving businesses. 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 for the domestic US market is becoming increasing complex for several reasons. First, the number of inter-exchange 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 a 500,000 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 H.323 network.
One of the major operational benefits of the TransNexus solution is its ability to normalize carrier rates quoted by LATA, OCN or Tiers into a simple NPA-NXX-X format that includes rates for partitioned NXXs. For each long distance call, the MetaSwitch queries the TransNexus platform for routing information. The TransNexus route server returns a routing prefix indicating which trunk group, SIP or TDM, the MetaSwitch should use to complete the call. In addition to automating least cost routing, the TransNexus solution also provides detailed traffic analysis reports and hourly billing reports. Reconciliation reports enable BroadRiver to validate their long distance carrier bills by providing a comprehensive summary of rated Call Detail Records (CDRs) for traffic routed to each long distance vendor. "The TransNexus software provides BroadRiver with a very efficient, centralized solution for managing all our inter-network telephone traffic – VoIP and TDM. The payback period based on just the least cost routing benefits was less than two months" according to Michael Oken, Vice President and Chief Technical Officer of BroadRiver. "In addition, the TransNexus technical support has been excellent." |
