Hodges and Lawrence K. Vanston, Ph.D. Description Who Should Read this Report? Table of Contents Figures Pricing/Ordering information Sponsored by TTFG Description  [back to top] Incumbent local exchange carriers (ILECs) still mostly use traditional circuit switching equipment for voice services. This represents a tremendous sunk investment: $62.5 billion in digital circuit switching at year-end 2006. Newer competitors are using VoIP (voice over Internet protocol) switching, which are significantly less expensive and much more flexible, especially in offering integrated applications. This study examines the main options available to ILECs regarding the future of their circuit switches and provides recommendations for depreciation lives.
