The CYS has grouped 128 European Technical Committees of ETSI and CEN as shown in Table 1 and established CYS MC 07 Mirror Committee which is in charge of monitoring their respective work.

CYS MC 07 which is now the national mirror committee monitoring the work performed by the European technical standardization committees dealing with Information Technology and telecommunications is composed by stakeholders coming from all interested parties (government departments, professional bodies, academic institutions, Consumer Association).
