33.040.30 - Switching and signalling systems

This standard applies to electrical equipment using signals in the frequency range 3 kHz to 148,5 kHz to transmit information on low voltage electrical systems, either on the public electricity distribution network or within installations in consumers’ premises.
It specifies the frequency bands allocated to the different applications, limits for the terminal output voltage in the operating band and limits for conducted and radiated disturbance. It also gives the methods of measurement.

Corrigendum to EN issued October 2006

This European product safety standard applies to the filter part of portable devices for household and similar uses (hereafter referred to as portable decoupling filters) consisting of the filter part, a plug or an appliance inlet or a provision for connection by terminals or with a non-rewirable cord and one (multiple) socket-outlet or an appliance outlet. They are intended for single-phase circuits for nominal currents not exceeding 16 A and for nominal voltages not exceeding 250 V a.c. to neu...view more

Revised PICS.

Request for a new edition of the V5.1 interface specification (part 1) to incorporate/include the amendments A1 and the changes in the PSTN restart procedures by leaving the DiSCONNECT COMPLETE message as it is and not send DISCONNECT COMPLETE in state AN1 or LE1 and treat the message as an unexpected message in the OUT OF SERVICE  state. The aim is also to include further comments discussed during the time frame not later than milestone 6 for this work item.

PICS proforma for part 1

Second edition of the V.5.2 interface will align with the second editi on of the V5.1 interface.

Update the test specifications to be in line with the 3rd edition of the base protocol standard.
