oSIST prEN 50561-2:2015

When user data are being transmitted by the PLC port the disturbances from the PLC port may exceed the
disturbance limits of Table 1 at frequencies between 1,6065 MHz and 30 MHz provided that within:
a) all the excluded frequency ranges given in Table A.1 — the level of the transmitted signals shall comply
with the disturbance limits given in Table 1 using the methods and procedures given in 9.1.
b) all the excluded frequency ranges given in Table A.2 the level of the transmitted signals shall comply
with one of the following requirements:
1) the disturbance limits given in Table 1 using the methods and procedures given in 9.1;
2) the dynamic frequency exclusion requirements given in 6.2;
3) the remote dynamic frequency inclusion requirements given in 6.3.
NOTE “Frequency inclusion” implies that those frequencies are excluded by default, and are only included in the
allowed set of carriers when explicitly authorized by an action from the management entity. When the link with the
management entity is not available, the PLC access network apparatus automatically returns to the default state.
Without user data transmission, the unsymmetrical disturbances from the PLC port shall comply with the
disturbance limits given in Table 1 between 150 kHz and 30 MHz using the methods and procedures given in
9.1.
The maximum transmitted signal from the PLC port shall not exceed the maximum values given in Table 2
measured using the methods and procedures given in 9.2.
The PLC port shall implement a dynamic power control function for the purpose of minimizing the probability
of radio disturbance while still maintaining communication. The dynamic power control function shall be
capable of reducing the output power to the maximum levels given in Table 2 measured using the methods
and procedures given in 9.2.
In order to ensure the inherent symmetry of the PLC port it shall, in all operating conditions, comply with the
disturbance limits given in Table 1 using the methods and procedures given in 9.4.

Maximum transmitted signal in dB(μV) (PK) 75 85 105
The transmit power management function of an AE should function in the same way
as the EUT otherwise the signal of the AE may dominate and cause erroneous
results during measurement.
6.2 Specific requirements for Dynamic Frequency Exclusion
Within 15 s of a ‘valid’ HF radio broadcast service being present within the excluded frequency band given in
Table A.2 the transmitted PLC signal level shall not exceed a symmetrical voltage level of 56 dB(µV) (AV) in
a 9 kHz resolution bandwidth.
NOTE 1 This level of the symmetrical voltage is derived from the EN 55022 Mains Conducted Class B disturbance
limit (5 MHz to 30 MHz), which is U = 50 dB(µV) (Resolution Bandwidth 9 kHz, AV).
AMN
The transmitted PLC signal shall avoid using the frequency of an identified radio broadcast service. The
minimum width of the excluded frequency band shall be 10 kHz (±5 kHz centred on the carrier frequency of
the broadcast signal). The excluded frequency band shall also comply with the requirements of Figure 1 in
order to avoid adjacent channel interference, with respect to AM / DRM protection ratios as defined in ITU-R
Rec. BS.560-4, BS.1615-1 and BS.703, from transmissions outside the notch.
If several neighbouring radio broadcast services are identified or a digital (DRM) service occupying more
than a single conventional channel, the width of the excluded frequency range shall be increased, scaled to
integer multiples of 5 kHz.
NOTE 2 Usually, the channels of radio broadcast services are allocated with a minimum spacing of 5 kHz. Also, the
centre frequency is a multiple of 5 kHz.
The excluded frequency band shall remain excluded continuously for the entire duration that the ‘valid’ radio
broadcast service is present. After the detection of a ‘valid’ radio broadcast service has ceased, the excluded
frequency band shall remain excluded for at least 3 additional minutes.

6.3 Specific requirements for remote dynamic frequency inclusion
The PLC access network apparatus shall notch by default all frequencies listed in Table A.1 and Table A.2.
The frequencies given in Table A.2 or some of them may be temporarily released while the external
management entity detects no valid broadcast service at those frequencies.
Frequencies where notches have been released shall comply with the limits given in Table 2 using the
method defined in 9.2.
As soon as the external management entity detects a valid broadcast service or the connection to the
external management entity itself is interrupted, the frequencies in Table A.2 shall be notched according to
the requirements given in 6.2.
NOTE This function assumes that the network management entity fulfils requirements similar to 6.2 in terms of
timing for the detection of a ‘valid’ broadcast service.

7 Requirement for radiated disturbances
The EUT shall comply with the Class B limits, using the measurement conditions and the methodology
defined in EN 55032 for radiated disturbances.
8 Measurement conditions for PLC ports
To perform the tests requiring user data transmission through the PLC port, the following procedure shall
apply:
- Determine the maximum possible data rate between the PLC ports of the EUT and AE in the test setup.
- Exercise the EUT PLC port to transmit user data at a rate in excess of 10 % of the maximal possible
data rate determined for the setup.
- As an example the transmission of a large data file or a software tool which creates arbitrary data
streams could be used to exercise the port.
For EUT with an AC mains output port, no device shall be connected to this port during testing.
9 Measurement methods and procedures for PLC ports
9.1 Conducted unsymmetrical disturbances
The PLC port of the EUT shall be assessed using an AMN in accordance with EN 55016-1-2:2004, 4.3, the
measurement method given in Clause 9 of EN 55032:2012, A.3 for the mains ports and the arrangement
shown in Figure 2 below for frequencies between 150 kHz and 30 MHz.
The Coupling System (see Figure 3) shall:
- Allow the EUT to be exercised by the AE;
- Have sufficient loss to ensure signals from the AE do not influence the measurement result;
- Ensure that the EUT can transmit at its maximum power level.
The insertion loss (symmetric) of the Coupling System between its two ports is required for:
- providing a defined insertion loss between the EUT and AE;
- stabilization of the differential mode impedance;
- attenuation of the differential mode signal of the AE;
- isolation of the common mode signal of the AE;
- filtering of the differential- and common mode signal from the mains.
Figure 3 shows an example of a coupling unit with a nominal insertion loss of 40 dB.
Measurements in the following operating conditions and configurations shall be performed:
