Note
The ISDN interfaces of the Gateway 400 support the Restricted Power Mode.
This may reduce the functionality of ISDN telephones (e.g., no permanent display) or
cause some telephones to not behave as expected (e.g., signaling of all incoming calls,
regardless of the configured MSN). If necessary, connect an ISDN bus power supply.
