1.3 Product Description

Basic Features

2N® StarGate / BlueTower is a compact yet highly sophisticated system. It supports full remote supervision and configuration via web interface or using an external modem over a BRI-ISDN and analogue line, or over a B channel in a PRI-ISDN trunk. The system has been designed and works with a lot of highly sophisticated functions, which make it fully client-oriented and highly reliable in cooperation with both GSM networks and ISDN. In addition, it provides full monitoring and comfortable (web interface) configuration without functional limitations. Configuration alterations can be made without resetting, i.e. under full operation. Hot-swappable plug-in GSM/UMTS boards, which can be swapped under full operation including SIM cards, are a matter of course. The use of up to eight SIM cards per GSM/UMTS module in combination with an intelligent SIM card switching tool and detailed statistics upgrade this system into a powerful LCR tool. There is also support of remote SIM cards (2N® SIM Star) and an external LCR machine (2N® External Routing Machine). High product stability is achieved by the fact that the gateway is programmed in the ASM, i.e. an OS-FREE system.  The system also features easy installation, simple operation and easy replacement of defective parts as it is composed of plug-in boards that communicate independently along system buses. As already mentioned, the system allows for an easy detection of defective parts, automatic locking against use and easy replacement (hot-swap). Thanks to the above-mentioned properties, the system can be installed and configured successfully within one hour!

Advantages of 2N® StarGate / BlueTower

  • Compact size, modularity and hot-swappable solution.
  • Up to 32 GSM/UMTS modules (8 in BlueTower).
  • Up to 256 SIM cards in a system (StarGate).
