xDSL and Voice over IP

Effective access solutions for rural/remote areas

CIG specializes in providing complex solutions for voice and data services in rural and remote areas. Such areas present challenge for any operators. That’s why the offered solutions should be carefully analyzed and reflect trends in the telecommunications industry, first of all - a transition to Next Generation Network (NGN). Internet traffic in North America exceeded voice traffic for the first time in 1998, surpassing in less than a decade the telephony market that has been growing for nearly a century. Since1995 the Internet economy growth has averaged 150%. With voice growing at 8%, in 7-10 years, voice will be a small minority of network bandwidth. The optimal strategy for the future is to handle voice as much as possible like data and use a single IP-based packet network infrastructure, or NGN, for both voice and data. This strategy has already started to work in many countries - IP telephony or Voice over IP (VoIP) has undercut a traditional long-distance telephony by offering as much as 80% saving over the fixed-line rates. It should be noted that NGN and the PSTN would co-exist for years, making smooth, cost-effective interoperability essential. NGN is associated with broadband. The only broadband network allows deployment of high speed data services and packetized voice services. Backbone networks have already become broadband. The critical problem is the deployment of broadband on the local loop. The local loops are the most expensive part of the entire network. Solutions for creation broadband local loops for rural/remote areas must meet the following requirements:

• support traditional and VoIP telephony,
• support xDSL services for high-speed Internet access and applications like Video on Demand,
• support VoDSL (multiple phones lines over a single copper pair),
• be cost effectively scalable at low numbers of subscribers/increments,
• be compact and environmentally hardened in order to be deployed in DLC remote cabinets,
• support different transport media between remote terminals and CO, first of all, wireless, to allow quick and cost-effective deployment,
• support Ethernet as an effective transport technology,
• minimize the use of CO space,
• provide remote operations, provisioning and maintenance.
