Technical Description (2)Standard Hardware Units

1. MBU (1-4)- Mounting Base Unit

The MBU is the mechanical mounting Inter-

face for the RBS 2308. It contains the inter-

face for the main power supply, and provides

surge and transient protection for incoming

lines. Circuit breakers for main power and

a switch for RRU power are located here.

2. IXU (1)- Interface and Switching Unit

The IXU is in the central control unit for oneRBS. All switching of traffic is performed inthe IXU. The IXU has integrated powersupply and climate control. The FlashMemory Card, the TIM, and all externalinterfaces except AC/DC power, antennasand the fan unit are located on the IXU.

The IXU is only used in RBS 2308 Master

2A. Flash Memory Card (1) 2A

All loadable software and the IDB are stored

on the Flash Memory Card. The cards

Contains all information for configuring

replacement units if RBS 2308s are

exchanged.

2B. TIM (1)Transmission Interface Module

2B

2A

The TIM provides an interface to various

transmission standards. Different TIMs can

be defined for different standards. Currently

only E1/T1 is supported.

3. RRU (1-3)- Remote Radio Unit

The RRU contains the transceivers;

it handles the combining and distributing

functions for the RBS 2308. The RRU has

integrated power supply and climate control.

4. Sunshields( 1 top, 1 front, 2 side / cabinet)

Main functions of the Sunshield are to reduce

heat from direct solar radiation and act as

lockable design cover.
