Nokia to Deliver USD 25 Million SDH Transmission System to TAC of Thailand
April 12, 1996
Nokia and Total Access Communications Public Company Limited (TAC) have signed a frame agreement for the supply of transmission equipment for the expansion of TAC’s regional transport network. The value of deliveries which will commence in April 1996 will total over USD 25 million.
Under the contract Nokia will deliver a nationwide SDH network on a semi-turn-key basis covering entire Thailand, and a network management system including a national management center and three regional management centers. The network is a nationwide Regional Transport network for TAC’s various operations, currently serving DCS1800 and AMPS cellular networks, trunking and paging. The network will enable TAC to rapidly expand their cellular services to cover the entire country while ensuring superior quality and reliability of service.
The fibre network consists of Nokia SYNFONET SDH node equipment with Multiplexing, Add-Drop, and Cross-Connection functionalities. Transmission capacities will range from STM-1 (155 Mbit/s) up to STM-4 (622 Mbit/s). The contract provides TAC with an option to acquire also Nokia’s STM-16 SDH equipment when higher capacities are required in the network. Nokia Digital Microwave Radios will be used in accessing the fibre network. The complete network will be managed by the Nokia NMS network management system.
The signed contract further strengthens Nokia’s position as one of the main suppliers to both cellular transmission solutions and DCS1800 infrastructure equipment to TAC.
TAC, a member in the UCOM Group, is a leading provider of wireless communications services in Thailand with the revenue of close to USD 300 million in 1995. TAC’s cellular operations consist of an analogue AMPS network and digital DCS1800 network. Total number of subscribers currently exceeds 500,000 and is increasing rapidly.
Note to editors:
SDH (Synchronous Digital Hierarchy) systems improve the capacity and availability in the telecommunications network. SDH enables the operator to e.g. supervise and allocate network resources for optimal performance at any time. SDH is also a platform for future telecommunications services.
