PROPOSED INTEGRATED TELECOMMUNICATIONS NETWORK

TECHNICAL REQUIREMENTS


BACKGROUND

Telecommunications services are crucial elements in the conduct of business activities. Its availability on a regular and uninterrupted basis is essential for the efficient functioning of industries, commerce and trade, offices and institutions; it contributes directly to the over all development of the city and its neighboring communities. In aspiring to achieve this goal, the members of the newly created Olongapo City Telecommunications and Information Technology Board consider TELECOM and Information technology as “top priority” among the programs to be developed in order to meet the ever growing demand of efficient and reliable TELECOM and IT infrastructures and services.

Inspired by the leadership of Mayor James Gordon, Jr. we at the TELECOM and IT Board, put a premium on rendering service to its residents, businessmen and investors by performing our individual tasks and with teamwork in striving to contribute our share to attain this goal.

The growth and expansion of SBMA economy and activities imposes a continuing need for efficient, reliable and cost effective Telecommunications to satisfy and identify the best Telecommunications and IT provider, particularly in the area of technical requirements. The following should be considered:
