The ZXG10 OB06 (V1.0) provides Abis interfaces and Um interfaces, as
well the cascade interface (defined as B interface) between OB06s,
interfaces of the tower amplification and local O&M interfaces.
The Abis interface is a communication interface between OB06 and BSC.
The Um interface is the interface between OB06 and MS. The B interface is
actually an extension of the Abis interface. The tower amplifier system
