2N BlueStar/Stargate GSM Gateway
Installation Notes

2N BlueStar

2N StarGate

The BlueStar supports 8 GSM boards (16 modules) and has an integrated Antenna splitter
The StarGate supports 16 GSM boards (32 modules) and requires an external Antenna splitter

The following has been compiled from the 2N Docs, and experience from other Techs in the field.
Use your own experience to fill in the blanks and adapt the settings to your own unique installation.

Further information: BlueStar manual | StarGate manual | AT Commands | PRI config program | 2N Telecoms Wiki

Key Notes:

AT commands: the serial data rate is 57600. When connected, enter the command: AT, and the CPU should respond OK.
To connect via telnet, the procedure is the same, except in PuTTY click Telnet and enter the CPU IP address.
Licenses: The initial license is only good for X amount of hours beginning when the ROM is placed on the CPU Card, not with power to the GSM. Typically, this license will expire before the equipment reaches the installation site. The first license will become invalid and a new license will be required after the X hours have passed.
Use the command ATI4 to print the factory number, which is required to obtain a new license. Or, in the configuration tool, goto: Gateway control ➤ Firmware / Licence : Information about gateway license, Load from Gateway.
SIM Cards: If you installing SIM cards from more than one cell carrier, make sure that they are separated in the gateway and control access in the PBX. By default, all SIM Cards are placed into Group 1 for incoming and outgoing calls. If Multiple SIM Card providers are used, a unique Group Id will need to be assigned to each carrier per GSM Card which has two modules. PINs MUST BE DISABLED ON ALL SIM CARDS OR ALL SIM CARDS MUST HAVE THE SAME PIN!
Check SIM credit with the command at&gXX=XTDussd, where XX is the GSM module and ussd the command.
Example: to check the credit on gsm module g08, the command is *101#, enter the following: at&g08=XTD*101#
Fiber Transceivers: Multi Mode SC 4048 Transceivers are designed specifically to work with 2.0 Meg PRI circuits with out-of-band signalling (a D-channel). All other Media Transceivers will not work.
PBX IS NETWORK (MASTER) if the GSM E-1 shares a cabinet with an E-1 that is connected to the local PTT, or other E-1 clocking source, GSM IS TERMINAL EQUIPMENT (SLAVE). Typically, two fields must be changed on the GSM gateway for the span to come up: "ISDN PRI port type: TE", and "Synchronization: Slave".
Test calls: connect a headset to the AUX interface. For example, to dial the number 741111111:
- Via LCR settings, route the call through LCR: AT!SG32= 9741111111
- To call through the first GSM module directly: AT!SG0= 741111111

PRI board:

The PRI RJ45 uses standard pairs 1 (pins 1&2) and 3 (pins 4&5). Transmit and receive pairs can be swapped by moving the TE/NT jumpers at JP2 & JP3. Note, these jumpers change only the pairs, the USR/SLAVE setting is done on the ISDN parameters screen.

Terminal (TE) mode:	Pair 1 - RX	Pair 3 - TX	The gateway is set to USR/SLAVE, the PBX is set to NET/MASTER.
Network (NT) mode:	Pair 1 - TX	Pair 3 - RX

Jumper JP4 activates/deactivates a back-up connection between PRI1 and PRI2 when the system is switched off, or the PRI board is faulty. By default, jumper JP1 is disconnected, jumper JP2 is connected as TE, jumper JP3 is connected as NT and JP4 is connected.

The front panel Layer 1-3 LED's indicate the following status:

Layer 3:	Active call	No active calls
Layer 2:	Established	Not established	Establishing
Layer 1:	Synchronized	Disconnected	Synchronizing

GSM board:

Each GSM board contains two GSM modules, each supporting up to 8 SIMs, though only one SIM card is connected to each GSM module at a time. Populate positions 1-1 (top left) and 2-1 (bottom right) to use both GSM modules with one SIM each.

The front panel GSM LED's 1 & 2 indicate the following status:

GSM module idle	SIM card initialization
GSM module in use	GSM module blocked or initializing
