AC ringing voltage (RWS)
AC ringing voltage is required for the central alarm bell (not included in PABX
scope of supply) for the PABX. The contact assembly through which the AC
ringing voltage is switched to the central alarm bell that must be connected
externally is located on the TFE module. AC ringing voltage may not be loaded
more than 15 mA.
Only possible in the slot for TFE1!.
