How does the GSM Gateway work

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.

Recommended settings at ISDN

side

Port: NT**Synchronization: MASTERTEI: 0

Port: TE**Synchronization: SLAVETEI: 0

E1*

* EuroISDN interface (Q.931 EDDS1)

** If you set 2N StarGate as NT(MASTER), set switch as TE (SLAVE)

Outgoing calls 8 independent outgoing GSM groups CLIP/CLIR features possibility for limitation of minutes Rotating of SIMs by time/random/limit

Incoming calls 4 independent incoming GSM groups possibility to REJECT/IGNORE incoming calls present with DISA message/dialling tone passing to switch/VoIP gateway

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.

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.

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).

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

Data records about traffic

• 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

Example of one line in CDR file

*with GSM modules GM22(47) IMSI is presented, with TC35 GSM modules serial number of SIM card is presented

CDR (Call Data Records)

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

Easy remote control
