2 Case Study PLDT Made up of over 7,000 islands in Southeast Asia, the Philippines has a population of 89 million. One of the Telco success stories of recent years, the Philippines has seen tremendous growth, especially in mobile communications. Increased demand for new services and functionality has fuelled investments in leading-edge technology for the country's communications infrastructure. About the customer Founded November 28, 1928, Philippine Long Distance Telephone Company (PLDT) started out as a POTS (plain old telephone service) provider. Now the leading telecommunications provider in the Philippines, PLDT offers the largest and most diverse range of telecommunications services across the country's most extensive fiber optic backbone and fixed line, cellular and satellite networks. PLDT's services are offered through its three principal business groups: Fixed line Wireless Information and Communication Technology The fixed line business group provides national and international long distance phone calls, data and other network services used for domestic and international communications, such as private networking and broadband Internet access. The wireless business group primarily offers cellular services, including wireless voice and data communications, as well as satellite and broadband network connectivity. The Information and Communications Technology business group operates call centres, Internet data centres, and an Internet and gaming business. The customer network With the increasing demands of modern communications, it is important for PLDT to keep its network infrastructure continuously updated to ensure delivery of advanced value-added services to both residential and business customers. The convergence of Voice, Video and Data traffic over the IP network necessitates using leading edge technology to provide seamless delivery of services. The Next Generation Network developed by PLDT offering both Voice and ADSL / ADSL2+ services saw a tremendous increase in access demand from both residential and business customers. PLDT now offers advanced solutions for residential and business clients as well as educational institutions.

Business customers are able to have 'always-on' Internet access enabled with services like I-Gate and BizDSL, for secure highspeed communications. Educational institutions making use of services like ecampus allows teachers and students to enjoy high speed wireless access to the school's LAN and the Internet anytime and anywhere. With these and many other offerings covering the whole spectrum of communications technology, PLDT's Next Generation Network needed the bandwidth and capacity for millions of users.
