KD Ontime Solution Description
KD Ontime’s multi-service platform supports local, national long distance, and international prepaid calling card voice services over a cost-effective packet voice architecture. This is an excellent solution for countries in which most users do not have direct access to a telephone. KD Ontime’s solution supports phone-to-phone and fax-to-fax calling, while the same platform can also be used to support enhanced services, such as calling card and Voice VPN.
KD Ontime provides Adesemi with a cost-effective, pre-paid/post-paid, centrally managed solution for VoIP calling over public or private networks. This solution provides full traditional calling card functionality over IP with superior proven voice quality. Adesemi can bypass the tolls and interconnection charges associated with circuit-switched networks, enjoy low-cost termination rates and expand its service destinations around the world via KD Ontime-certified partners. Advanced features include real-time (prepaid) billing and a flexible IVR supporting multiple languages, currencies and call flows. Virtual dialing plans enable Adesemi to support incoming calls to Public Pay Phones.
Network Overview
KD Ontime’s solution is implemented for Adesemi as part of a multi-vendor network architecture, including WLL and VSAT solution providers. In this deployment, KD Ontime’s customer premise equipment (CPE) gateways interface WLL equipment provided by Wiman. It is possible to co-locate a WLL base station with a VSAT earth station, which communicates with the satellite.
The initial deployment at Adesemi, which took place in 2002, includes seven Points of Presence (POPs). KD Ontime’s carrier-class VGW2000 gateways are located in each POP for interfacing the incumbent local carrier, NITEL, and GSM network. KD Ontime CPE gateways (VGW8) are deployed at the respective endpoints (CyberCafe, Public Pay Phone or corporate offices), each supporting up to 8 analog lines. The VGW8 can also be configured to interface the corporate PBX. The POPs are connected to the endpoints via WLL technology. Long distance calls within Nigeria are transmitted between Adesemi’s PoPs via satellite (VSAT). Connection to international networks is also supported by the VSAT network.
