2.1.2.4 Ethernet Infrastructure incl. Gigabit Ethernet Switched (GES)
The infrastructure for data transport is based on 1Gigabit Ethernet Switches (GES). Two
kinds of cables can be used for the interconnection: CAT5 (or higher) for distances of
maximum 100m (300ft) and optical fibers for longer distances. The GES support Power over
Ethernet (PoE).

2.1.2.5 Network Management System (NMS) Server
The NMS is in charge of:
Configuring the network elements
Mapping of RRH to BSI
Operation and administration
Supervision of system (monitoring and control functionality)
Maintenance of system
2.1.3 System Structure (deployment architectures)
ClearFill®Star allows building a star configuration (see Figure 8(a)), i.e. all RRH of the same
sector reside on the same switch level. It also allows a tree configuration (see Figure 8(b)),
i.e. RRHs of different sectors may reside on different switch levels.
