DEVELOPMENT OF TECHNICAL CODE S 
 
 
The Communications and Multimedia Act 1998 (‘the Act’) pro vides for Technical Standards Forum 
designated under section 184 of the Act or the Malaysian Communications and Multimedia 
Commission (‘the Commission’) to prepare a technical code. The technical code prepared pursuant to 
section 185 of the Act shall consi st of, at least, the requirement for network interoperability and the 
promotion of safety of network facilities.  
 
Section 96 of the Act also provides for the Commission to determine a technical code in accordance 
with section 55 of the Act if the technical  code is not developed under an applicable provision of the 
Act and it is unlikely to be developed by the Technical Standards Forum within a reasonable time.  
 
In exercise of the power conferred by section 184 of the Act, the Commission has designated the 
Malaysian Technical Standards Forum Bhd (‘MTSFB’) as a Technical Standards Forum which is 
obligated, among others, to prepare the technical code under section 185 of the Act.  
 
A technical code prepared in accordance with section 185 shall not be effective u ntil it is registered by 
the Commission pursuant to section 95 of the Act.
