5How does the GSM Gateway work GSM Gateway is a device for direct routing of GSM calls through its GSM modules into GSM network. Otherwise, routing of these calls through PSTN network to the GSM network would be much more costly.While using GSM gateway, there is no interconnect fee besides bills from SIM cards, which are used in GSM Gateway.The calls may originate in company’s PBX, in alternative carriers networks etc. E1 or VoIP connection to 2N StarGate is supported.
6Recommended settings at ISDN side * EuroISDN interface (Q.931 EDDS1)** If you set 2N StarGate as NT(MASTER), set switch as TE (SLAVE)E1*Port: NT**Synchronization: MASTERTEI: 0Port: TE**Synchronization: SLAVETEI: 0

8Outgoing calls settings 1. Assign GSM Modules to GSM groupsEvery single GSM Module may be assigned to one outgoing group and one incoming group. Incoming and outgoing groups are two different sets of groups.4. Define LCRLCR (Least Cost Routing) algorithm assigns GSM Groups to Network lists together with time dependency. In other words it says, through which GSM Modules will be calls routed (according to its prefix).2. Configure every GSM Group separatelyEvery set of GSM Modules (creating GSM Group) is configured separately. Configuration include CLIP/CLIR options, times of usage, minutes limit etc.3. Create network lists (one for each GSM network)Every Network list contains list of prefixes, which will be routed together with the same rules. Usually a Network list corresponds with all prefixes for one GSM Network.
9Data records about traffic CDR (Call Data Records)2N StarGate automatically saves information about every call into its memory (even unsuccessful calls if needed). With latest CPU board you have space for up to 245 thousand lines. In CDR you will find data about every call, which has been connected through 2N StarGateStatistics2N StarGate automatically generates detailed statistics data on all incoming and outgoing calls.. In Statistics you will find data about number of minutes routed through every GSM module, GSM Group
