More information

Basic information
 

Modular system

  • Gateway configuration in basic version: 2 GSM lines (2 SIM cards) with 1 ISDN NT/TE port
  • Extension to 4, 6 or 8 GSM lines (4, 6 or 8 SIM cards) with 2, 3 or 4 ISDN NT/TE lines in the same unit
  • One and the same housing regardless of configuration
  • 1 antenna connector for 2, 4, 6 or 8 GSM lines (build-in antenna combiner included)
  • 1 power supply for the complete concept
 

ISDN configuration

  • ISDN S0 port configured as NT - emulates the city line - connection of the gateway to the PABX city line port
  • ISDN S0 port configured as TE - emulates terminal termination - connection under the internal contact S0 of the PABX
  • Operation in mode "Point-to-Point" or "Point-Multipoint"
  • Depending on the version, the gateway is available with 1, 2, 3 or 4 ISDN ports (2 GSM channels for each ISDN port)
