conversion,

Bipolar-to-Unipolar Code Conversion The signals applied to the TRAFFIC IN terminal are (*) 2.048 Mbps data streams in a bipolar pulse format of the high density bipolar-3 (HDB-3) code. Each bipolar-coded data stream is converted into an NRZ unipolar data stream. Note: *2 MB × 2 system: two 2 MB × 4 system: four 2 MB × 8 system: eight 2 MB × 16 system: sixteen

2.1.2

2.1.2

Multiplexing To obtain time slots for multiplexing, the 2.048 Mbps × N data streams are written in to a buffer memory and read out with radio section clock having a time gap. The data streams having a time gap are sent to a multiplexer (MUX) circuit, here, alarm information, AIS RCVD, loopback control/ answer, alarm/control signals and stuff information bits, etc. are inserted into the location of the time gap.

2.1.3

Parallel-to-Serial Conversion The signal streams which are formatted in radio frame, are fed to the DPU circuit.

2.2

Transmit Digital Processing This section describes the multiplexing, scrambling and parity check.

2.2.1

Multiplexing The data streams having a time gap are sent to the MUX in which frame pattern, multiframe pattern, analog service channel (ASC), digital service channel (DSC), WS, LAN data signals and parity check bits are inserted into the respective locations of the time gap. The multiplexed data streams are fed to the SCRB circuit.

2-17


2.2.2

ROI-S04488

Scrambling To smooth the RF spectrum and to restore the clock at the receiving end, the multiplexed data streams are scrambled with the 12th (for 4 x 2 MB) or 14th (for 2 x 2 MB, 8 x 2 MB and 16 x 2 MB,) pseudo random pattern generated by the timing generator (TIM GEN) so that the transmission mark ratio is 1/2. Then the scrambled data stream is sent to the differential encoder (DIFF ENCOD).

2.2.3

Parity Check For detecting the bit error at the receiving end, the parity check bits are calculated and multiplexed into the radio frame signal streams.

2.3

Modulation This section describes the differential encoding, 4-phase shift keying modulation and orderwire signal modulation.

2.3.1

Differential Encoding In the 4-phase shift keying modulation system, the demodulator phase may not coincide with the modulation signal of the opposite transmitting end which give raise to phase ambiguity. To avoid this, an absolute reference phase is needed between the transmitting and receiving ends. As shown in Table 2-1, the two independent data streams fed from the SCRB circuit are represented as an arrangement of Gray-coded binary digits. The two-bit Gray-coded data streams are then converted into pulse streams in natural binary code for facilitating differential encoding. Table 2-1 Binary Combinations DECIMAL

4-Phase Shift Keying Modulation To permit 4-phase shift keying modulation, the encoded data streams are converted into two separate two-level baseband signals for the P and Q channels by the digital-to-analog converter (D-A CONV) on the MOD section according to the logical status (see Fig. 2-3). To limit the associated transmitter output power spectrum, the voltage spectrum of the two-level baseband signal is shaped by each low-pass filter. The filtered signals are applied to a 4-phase modulator (4PH MOD). To obtain an 850 MHz IF carriers for 4PH MOD, an 850 MHz carrier is generated by the 850 MHz voltage controlled oscillator (VCO), and is split into two for the P and Q channels. The 850 MHz carrier for the Q channel is phase-shifted by π /2 from the P channel. The MOD modulates each of the 850 MHz carriers with a related twolevel baseband signal, and combines the modulated 850 MHz signals on the P and Q channels to arrange a four-phase assignment as shown in Fig. 2-2. The obtained 850 MHz IF signal is filtered by a LPF for eliminating the out-of-band components, amplified up to the required level by an automatic gain control (AGC) amplifier and sent to the ODU. Then, it is combined with 450 kHz amplitude-modulated engineering orderwire (EOW) signal and 10 MHz amplitude shift keying (ASK)-modulated control signal.

2.3.3

Orderwire Signal Modulation To facilitate an EOW between the IDU and ODU, the EOW signal is amplitude-modulated with the 450 kHz carrier by the orderwire modulator (EOW MOD) on the MOD section. The modulated EOW signal is filtered to eliminate higher out-of-band noise, amplified up to the required level and combined with the 850 MHz IF signal through a band-pass filter (BPF). This eliminates lower out-of-band noise, receiving IF signal (70 MHz), and an arrester (ARSR) protecting the equipment from harmful voltages caused by lightning.

2.4

Demodulation This section describes the EOW and alarm signal demodulation, main signal demodulation and differential decoding.

2.4.1

EOW and Alarm Signal Demodulation The received (RX) signal from the ODU contains a 70 MHz IF signal, 468 kHz amplitude-modulated EOW signal and 10 MHz ASK-modulated alarm (ALM) signal. The RX signal is branched into two separate signals; One is sent to the DEM section through the BPF which eliminates the transmitting IF, EOW and ALM signals, and the other goes through a BPF which eliminates the 70 MHz IF signal. The orderwire demodulator (EOW DEM) demodulates the 468 kHz amplitude-modulated EOW signal. The demodulated 10 MHz ASK alarm signal is sent to the CPU for further processing.

ROI-S04488

2.4.2

Main Signal Demodulation The incoming 70 MHz IF signal is amplified up to the required level by an AGC amplifier and split into two separate signals for the P and Q channels and then fed to the mixer. In addition to the 70 MHz IF signals, two carriers having a phase difference of π/2 produced by the carrier recovery circuit, which consists of a carrier synchronizer, a 70 MHz oscillator, and a carrier splitter (π/2), are applied to the decision circuit. In the decision circuit, each 70 MHz IF signal is coherent-detected with the related carrier to represent the original baseband signal corresponding to the phase assignment (see Fig. 2-4).

Fig. 2-4 Demodulation

The clock oscillator circuit generates a 38.383 MHz clock for the analogto-digital converter (A-D CONV) circuits. In the A-D CONV, two 38.383 Mbps data streams are regenerated with 38.383 MHz clock. Then the two re-generated 38.383 data streams enter the differential decoding (DIFF DECOD) circuit.

2.4.3

Differential Decoding The process of differential decoding is the reverse of the differential encoding at the transmitting end. In the natural binary-coded pulse streams, the phase of the time slot leading one bit before an incoming time slot is subtracted in quaternary notation from that of the incoming time slot. The decoded 38.383 Mbps data streams are sent to the frame synchronizer and descramblers on the DPU section of the MAIN BOARD for receive digital processing.

2.13 Alarm and Control Functions Alarm and control functions of the IDU are described herein. Fault detection circuits are provided in the IDU, sending signals to give alarm indications and remote alarm reports (see Fig. 2-1, Fig. 2-2 and Table 2-3). The alarm signals initiated by detection circuits in the ODU are also sent to the IDU. Therefore, the total alarm indications for the IDU and ODU are provided by the IDU and ODU indicators on the IDU. When the equipment is operating normally, these indicators on the IDU stay unlit. When an abnormal condition occurs in the IDU (except power supply failure), the IDU indicator lights and a remote alarm report is made. The same applies for the ODU indicator. To monitor/control the alarm and status of IDU/ODU, PM CARD module communicates with pasolink network management system (PNMS) or pasolink network management terminal (PNMT) via RS-232C (19.2 kbps). The PM CARD (Pasolink Management Card) provides the following functions: • Communication with PNMS and PNMT • Communication with ALM CONT of the IDU • Communication with opposite PM CARD • Data collection of performance monitor • Forward input housekeeping alarm signals to PNMS or PNMT • Outputs of dry contact by control from PNMS or PNMT

2-27


ROI-S04488

The PM CARD collects up to 300 items of events and performance information from IDU and ODU, and stores performance information for up to eight days. Notes in the Table 2-3 are as follows. Notes:*1. These alarms are initial value condition (for setting method, refer to paragraph 3.4.2 in this Section III). * 2. The alarm indication depends on system requirement (for setting method, refer to paragraph 3.4.2 in this Section III). * 3. The WS alarm indications can be inhibited. The WS alarm items are masked when the WS is not provided. 1. In an alarm condition, when the equipment is set to maintenance condition, the TX ALM, RX ALM and BER ALM for remote reporting are disabled. 2. When the IF cable between the IDU and ODU is electric short circuit condition or open condition, the IDU and ODU ALM LEDs are synchronously flashing.

4. MAINTENANCE This section provides instructions for periodic maintenance and corrective maintenance of the IDU. Also included is information on precautions, test equipment and accessories.

4.1 Precautions The following maintenance.

precautions

must

be

carefully

observed

during

1. The −43 V DC power is superimposed on the centre conductor of the coaxial cable between the IDU and ODU. Connecting a measurement set directly may damage the test equipment and touching the coaxial cable core may cause electrical shock. So, power down IDU before disconnection or connection of cable. 2. To protect the internal circuits against electrostatic discharge, engineers are requested to wear a wrist band and connect it to the frame ground terminal (FG) for Electrostatic Discharge (ESD) before detaching the shield cover (see Fig. 4-1). 3. Before the start of maintenance, including operation of the OPR SEL SW on the front panel of the equipment, select the equipment to maintenance mode using the LCT. After all operation for maintenance have been completed, perform MAINT OFF setting. 4. Do not turn on the power of the IDU leaving cable connection between the PC and RA PORT of the IDU. 5. Replacing the IDU, if new IDU has a history to be used in other hop, the new IDU may has former frequency channel setting and may make the ODU to transmit in an undesired TX frequency. NEC recommend to set the frequency channel before connecting the ODU.

Before beginning maintenance, notify the opposite station that maintenance is about to begin.

(b) After equipment start-up, allow the equipment to warm up for at least 30 minutes. (c)

After completing the maintenance operation, restore all connections to normal.

(d) In 1+1 system, to power ON the IDU, take the following steps. (1) When neither channel No.1 nor No.2 are working, first set the OPR SEL switch to the desired (No.1 or No.2) position and power on the selected MD unit or set the OPE SEL switch to neutral (Auto) position and power on both MD units. (2) When either channel No.1 or No.2 is working, set the OPR SEL No.1-No.2 switch on the IDU to the working channel side, then, turn on the power switch of the not working channel. (e)

During maintenance, the IDU is set to maintenance condition using a PC as described in 4.2 Maintenance Condition Setting:

Caution:

4.5 Corrective Maintenance Here, corrective maintenance in the field is described, and covers fault isolation, equipment replacement and alignment. When the equipment is faulty, it should be replaced with a spare. Replacement for the IDU is at the equipment-level in 1+0 system. Replacement for the IDU of 1+1 system is at panel-level (No.1, No.2 or SW unit) (see Fig. 4-2). During corrective maintenance, carefully observe the precautions given in paragraph 4.1 until alignment is completed.

4.5.1 Fault Isolation Flow Chart Alarm conditions are identified through: • Alarm LED (red) indication on the IDU or • Notification from external equipment During alarm conditions, red alarm LEDs on the IDU are lit except when there is a power supply failure. Faults can be isolated using the LED indicators on the front panel of the IDU. Table 4-4 provides information for isolating faults at a station. Connect the LCT to the equipment and check the equipment conditions in according with the flow chart are shown in Fig. 4-2 to Fig. 4-5. Refer to para. 3.4.2 for monitoring procedure using the LCT.

4.5.2 Replacement The Manufacturer does not recommend replacement of modules in the IDU (for 1+0 system) or Unit (for 1+1 system). Whenever a fault is identified on the IDU, the complete IDU equipment or Unit should be replaced with a spare. The faulty equipment is to be returned to the factory for repair. Whenever any unit fails in 1+1 system, replace only the unit that fails with a spare as described in procedures below. Caution: While the power supply is ON, do not remove/connect the power supply connector. Otherwise, the DC-DC CONV may fail. Caution: Before the start of maintenance, including operation of the OPR SEL SW on the front panel of the equipment, select the equipment to maintenance mode using the LCT. After all operation for maintenance have been completed, perform MAINT OFF setting. Caution: Do not disconnect IF cable between the IDU and the ODU in operating condition, if not, may damage the IDU and ODU. Do not remove/connect the IF cable with IDU power ON, turn IDU power OFF before remounting the IF cable. Caution: While the SW UNIT replacement is proceeding, the traffic is interrupted. Caution: It is recommended that you connect the IDU to ODU after the TX/RX frequency and TX power control setting has been set on the IDU. This process is most important for the following ODUs that may be emitted TX power if you set the channel number to "0ch" which is not defined (excepting 13/26/38 GHz band) by the Radio Frequency Assignment. Code No. of Corresponding ODU: H0738 (7 GHz), H0739 (8 GHz), H0330 (13 GHz), H0331 (15GHz), H0332 (18GHz), H0333 (23 GHz), H0334 (26 GHz), H0335 (38 GHz)
