Technical specification
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)
- Possibility of parallel use of two ISDN ports for LCR function - one ISDN port in TE mode connected to the PSTN network, second port in NT mode connected to the PABX control panel (optional)
