2. SYSTEM CONFIGURATION
This system consists of TRP-[ ]G-[ ] Transmitter-Receiver (Outdoor Unit(ODU)) and MDP-[ ]MB-[ ] Modulator-Demodulator (Indoor Unit (IDU))and Hybrid (see Fig. 2-1).
The [ ]GHz 4 MB (2 MB × 2) digital radio system is used to communicatetwo data streams at 2.048 Mbps (equivalent to 30 voice channels) betweentwo stations.
The [ ]GHz 8 MB digital radio system is used to communicate one datastream at 8.448 Mbps (equivalent to 120 voice channels) or four datastreams at 2.048 Mbps (equivalent to 30 voice channels) between twostations.
The [ ]GHz 17 MB (2 MB × 8) digital radio system is used tocommunicate eight data streams at 2.048 Mbps (equivalent to 30 voicechannels) between two stations.
The [ ]GHz 34 MB digital radio system is used to communicate one datastream at 34.368 Mbps (equivalent to 480 voice channels) or sixteen (16)data streams at 2.048 Mbps (equivalent to 30 voice channels) between twostations.
A system block diagrams of 2 MB × 2, 2 MB × 4, 2 MB × 8 and 2 MB ×16 systems are shown in Fig. 2-2, and that of 8 MB × 1 and 34 MB × 1systems are shown in Fig. 2-3.

5. ALARM AND CONTROL
The simplified alarm and control functions are described in accordancewith the following items:
• Alarm indication and reporting
• Protection switching for main traffic
• Protection switching for WS *, ASC and DSC
Note: * Applies only to the 2 MB × 16 and 34 MB × 1 systems(optional).
• Network Management (Optional)
5.1 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 theIDU. Therefore, the alarm indications for the ODU are indicated by thealarm indicators on the IDU. The alarm indications for the IDU are alsoindicated by the alarm indicator on IDU. When the equipment isoperating normally, the alarm indicators on the IDU stay unlit. When anabnormal condition occurs, the alarm indicator and a remote alarm reportis made (see Table 2-3 in MDP Equipment Description).

5.2 Protection Switching for Main Traffic
A block diagram of protection switching for main traffic of the HS systemis shown in Fig. 5-2. Protection switching in this system is performed bythe RF CKTs of the ODUs at the transmitting end. Either signal in paralleltransmission (No. 1 and No. 2 channel) is normally selected. At thereceiving end, protection switching is performed by the RX switch on theSW BOARD of the IDU.
The control for RF CKTs of the No.1 and No.2 channel ODU/ RX SW ofthe IDU is made in any of the manual, remote and automatic switchingcontrol. The switching control priorities are shown below.
• Priority 1 - Manual switching control
• Priority 2 - Remote switching control
• Priority 3 - Automatic switching control
The manual switching control is performed by the OPR SEL No.1-AUTONo.2* switch on the IDU, the remote switching control by the functionkeys of the external equipment, and the automatic switching control** bythe alarm signal produced at the ODU and/or the IDU. In any of theswitching controls, a switch control signal is produced by the switchcontrol logic circuit on the SW BOARD to select a desired/normalchannel. For the switch control logic circuit, nonhoming type is employed.The nonhoming type switch control circuit produces a switch controlsignal to keep the channel selected at the prior switching. The switchingcondition is indicated by the TX OPR 1, TX OPR 2, RX OPR 1 and RXOPR 2 indicators on the IDU.
Notes: 1.* Switching the with OPR SEL No.1-AUTO-No.2 switch actsboth the transmit and receive sides at the same time.
2.**TX and RX switchover are independently performed.
5.2.1 Transmit Switching
When either the No. 1 or No. 2 channel fails, the ALM CONT circuit onthe SW BOARD of the IDU produces the T PWR CONT signal forselecting the normal channel. The T PWR CONT signal sends to RF CKTon the ODU of the normal channel. The ODU of the normal channeloperates to pass the data signal. The switching condition is indicated bythe TX OPR 1 or TX OPR 2 indicator on the IDU.

5.2.2 Receive Switching
When either the No. 1 or No. 2 channel fails, the ALM CONT circuit onthe SW BOARD of the IDU produces the RX SW control signal forselecting the normal channel. The RX SW control signal sends to the SWBOARD. Accordingly, the RX SW on the SW BOARD operates to passthe data stream. The switching condition is indicated by the RX OPR 1 orRX OPR 2 indicator on the IDU.
5.3 Protection Switching for WS, ASC and DSC
Protection switching for WS*, ASC or DSC signal is performed by theswitch on the SW BOARD of the IDU at the receiving end. Normally,either signal in parallel transmission (No.1 and No.2) is selected at thereceiving end.
When either the No. 1 or No. 2 channel of the main traffic fails, the ALMCONT circuit on the IDU produces the RX SW control signal for selectingthe normal channel. The RX SW control signal sends to SW BOARDcircuit. Accordingly, the selector (SEL) on the SW BOARD circuitoperates to pass the signal.
Note: * Applies only to the 2 MB × 16 and 34 MB × 1 systems(optional).
5.4 Network Management (Optional)
Configuration of network management system (NMS) is shown in Fig. 5-3. Pasolink network management system (PNMS) is connected withNMS/RA of IDU, and pasolink network management terminal (PNMT) isconnected with LA PORT in IDU to provide monitoring the status of thepasolink and actual microwave link, and also controlling the equipmentstatus. Communication with the remote station units is performed usingone of DSC channels.
