A Technical Specification is a Standard which prescribes the minimum technical requirements to be fulfilled by telecommunication equipment intended for sale and use in Singapore.
IMDA also publishes Reference Specifications & Documents which describe the network and network-to-network interface (NNI) standards adopted or yet to be adopted by operators in Singapore. Consistent with the policy of technological neutrality, these NNI standards are for general information of or reference by operators, equipment suppliers and the public.
The Telecommunication Standards Advisory Committee ("TSAC") is formally established to provide IMDA with the above telecommunications standards-setting recommendations.
