GEHUB

The GEHUB is the GSM E1/T1 High level Data Link Control Unit for the Abis interface. It can be installed in slots 18-27 in the GMPS/GEPS. When the BSC need not process packet services, the GEHUB can also be installed in slots 14-15. The GEHUB can work in active/standby mode and work independently.
