4. How does the GSM Gateway work

5. How 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.

6. Recommended 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: MASTER
TEI: 0
Port: TE**
Synchronization: SLAVE
TEI: 0

7. The GSM side Outgoing calls 8 independent outgoing GSM groups
CLIP/CLIR features
possibility for limitation of minutes
Rotating of SIMs by time/random/limit
GSM network 1
GSM network 2
Incoming calls
4 independent incoming GSM groups
possibility to REJECT/IGNORE incoming calls
present with DISA message/dialling tone
passing to switch/VoIP gateway
GSM network 3

8. Outgoing calls settings
1. Assign GSM Modules to GSM groups
Every 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 LCR
LCR (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 separately
Every 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.

9. Data 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 StarGate
Statistics
2N 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

10. CDR (Call Data Records)
Example of one line in CDR file
** /11:07:53 O-OK CAU-016 aux/g02 GRP-1 0:23 001: /
1. column: **
2. column: date/time of start of the call
3. column: type of call
-I-FD : Unconnected attempt of incoming call (It will be implemented at higher version of the firmware)
-I-OK : Successfully connected incoming call (It will be implemented at higher version of the firmware)
-O-FD : Unconnected attempt of outgoing call
-O-OK : Successfully connected outgoing call
4. column: CAUSE sent to ISDN
5. column: number of used B-channel/number of used GSM module
6. column: used GSM group
7. column: time of establishing call
8. column: duration of call mmm:ss (max. 255:59) or error cause for unconnected calls
8. column: costs of the call (will be implemented in higher version of firmware)
9. column: called number
10. column: caller number
11. column: number of slot/IMSI* of used SIM card
*with GSM modules GM22(47) IMSI is presented, with TC35 GSM modules serial number of SIM card is presented

11. Easy remote control
2N STARGATE can be configured and supervised (remotely or locally) using the following connections:
locally via an RS232 interface
ISDN (or analogue) modem connected to an RS232 interface. An automatic detection of the modem connection and thus automatic modem configuration are a matter of course
10baseT interface - TELNET
Inbound B-channel in PRI ISDN connection

12. Other 2N PRI GSM Gateways
2N BlueTower
2N BlueStar

13. 2N BlueTower Up to 8 GSM channels – scalable capacity
Up to 2 PRI ISDN ports
Internal or external antenna splitter
Comfortable remote control and maintenance

14. 2N BlueStar Up to 16 GSM channels
Connection to your PBX via PRI ISDN (2x)
VoIP interface
