GFGUB

The GFGUB is the GSM Fast ethernet and Gigabit ethernet Unit for the Abis interface. It can be installed in slots 18-27 in the GMPS/GEPS. If the BSC need not process packet services, the GFGUB can be installed in slots 14-15. The GFGUB can work in active/standby mode and work independently.

• Functions of the GFGUB
  The GFGUB enables the FE/GE transmission on the Abis interface.
• GFGUA/GFGUB/GFGUG(FG2a) Panel
  The physical boards of the GFGUA, GFGUB, and GFGUG are the same. After being loaded with different software, the physical boards perform different functions. These boards have the same appearance and the same LEDs and ports.
• LEDs on the GFGUA/GFGUB/GFGUG(FG2a) Panel
  The physical boards of the GFGUA, GFGUB, and GFGUG are the same. After being loaded with different software, the physical boards perform different functions. These boards have the same types of LEDs on the panels: RUN, ALM, ACT, LINK (for Ethernet port), and ACT (for Ethernet port).
• Ports on the GFGUA/GFGUB/GFGUG(FG2a) Panel
