2. SYSTEM CONFIGURATION
This system consists of TRP-[ ]G-[ ] Transmitter-Receiver (Outdoor Unit
(ODU)) (see Fig. 2-1) and MDP-[ ]MB-[ ] Modulator-Demodulator
(Indoor Unit (IDU)) (see Fig. 2-2 and Fig. 2-3 ).
The [ ]GHz (2/4/8/16 x2 MB) MB digital radio system is used to
communicate from 2 to 16 data streams at 2.048 Mbps and/or up to 2
channels 10BASE-T/100BASE-TX LAN signals between two stations.
The system block diagrams of 2/4/8/16 x2 MB systems are shown in Fig.
2-4 and Fig. 2-5.

For details, refer to Appendix "Frequency Allocation Table" in TRP
equipment (ODU) description (Section II).

ALARM AND CONTROL
The simplified alarm and control functions are described in accordance
with the alarm indication and reporting, and network management.
Alarm Indication and Reporting
Alarm indication and reporting function are provided with the IDU. Alarm
signals initiated by detection circuits on the ODU are sent to the IDU.
Therefore the alarm indicator for the ODU is located on the front panel of
the IDU. The alarm indication for the IDU is also indicated by the
corresponding alarm indicator on the IDU. When the equipment is
operating normally, the alarm indicators on the IDU stay unlit. When an
abnormal condition occurs, the related alarm indicator is lit and a remote
alarm report is made
