KD Ontime’s Solution Description KD Ontime offers a cost-effective, pre-paid/post-paid, centrally managed Calling Card solution for VoIP calling over public or private networks. This solution provides full traditional calling card functionality over IP with superior proven voice quality. Service providers can bypass the tolls and interconnection charges associated with circuit-switched networks, enjoy low-cost termination rates and expand their service destinations via KD Ontime-certified partners. The prepaid Calling Card solution lets service providers capture non-subscriber revenue, while avoiding consumer credit risk. Advanced features include real-time (prepaid) billing and a flexible IVR supporting multiple languages, currencies and call flows. Network Overview Liaoning Telecom rolled out its calling card services in June 2000. Liaoning Telecom’s VoIP network was initially comprised of a single Network Operations Center (NOC) and three POPS in Shenyang, Jinzhou and Dalian. Each POP contained two carrier-class VGW2000 gateways, controlled by three KD Ontime Gatekeepers in the NOC. The KD Ontime Network Manager is installed in the NOC and performs central management for the entire network. Billing is performed through an interface to MIND’s advanced billing system. Due to the high quality and attractive rates of the calling card service, Liaoning Telecom’s business developed very quickly. Within several months, the network began to experience problems related to congestion and overloading. After examining the issue, Liaoning Telecom management made the decision to expand. Three additional POPs were added in Anshan, Liaoyang and Huludao, and network capacity was increased from 56 to 156 E1s. This expansion was completed in February 2001 and effectively resolved the previously encountered network problems.
