†Note: For more information, see Chapter Relay application: Communication application .
For applying N=3 frame, set Wide for scheme switch [CH*_COM_WIDTH].
(ii) Operation of TFC countermeasure in DIFLG
The user should set On for scheme switch [DIFGL-TFC-EN] when the TFC countermeasure is
required in the DIFGL function. Note that Off is set in the scheme switch, as default.
Sending DIFGL operation signal for the opposite
The signals of the DIFGL elements should be exchanged mutually for the both terminals.
Figure 2.6-6 shows the DIFGL elements; the operated signal “DIFGL” is set for the opposite
by the communication.
