Digital GSM Gateways (BRI) are used for saving costs related to calls to GSM from landlines by the smart directing of calls to two different operators (2 SIM cards inside the gateway). BRI gateways are very common among users who use an ISDN BRI connection as it is possible to connect to any digital PBX!
With the option of connecting to a free port of a digital PBX The user chooses from 2 versions - 1SIM/2SMI (calling one/two operators).
The 2N ISDN GSM Gateway (GSM router) connected to a PBX ISDN port (BRI, So) transmits GSM services to ISDN user terminals. In addition to cost-efficient calls, it provides the following services: calling line identification presentation (CLIP), connection status displaying, advice of charging (AOC), SMS send/receive using the ISDN telephone set, and billing data recording.
DISA provides DDI from the GSM network. The ISDN BRI GSM Gateway (ISDN router) welcomes the calling party with a DISA message and receives the number in the DTMF mode. Then, it converts the number into the DDI (in the PTP configuration) or MSN (in the PTMP configuration) mode. The least-cost routing (LCR) service helps establish connection alternatively by analysing the number (e.g. via the "netcall", etc.). The originally dialled number is completed as required by the Gateway program setup.
All called numbers, including connection date and time, are recorded in the 2N ISDN GSM Gateway buffer. Outgoing calls are checked by the call barring table, which disables expensive calls.
2N development department has implemented an interesting feature for those who don't want to learn 2N's ISDN BRI GSM Gateway configuration - Dynamic Clip Routing on ISDN-BRI Gateways. This feature enables you to make configuration settings on your company PBX only without programming our 2N GSM Gateways.
