5.4.2 From the PO1/PH1 Board to the E1 PanelWhen the IDU 605 uses an E1 panel as the DDF, use this E1 cable to connect the IDU 605 tothe E1 panel. Use a DB44 connector at the end of the E1 cable that is connected to the IDU 605,and use a DB37 connector at the other end that is connected to the E1 panel.Each E1 cable can transmit eight E1 signals. The interface impedance of the E1 cable is 75 ohms.

5.6 Network CableNetwork cables are used to connect Ethernet equipment. Both ends of a network cable use RJ-45connectors.RJ-45 connectors have two types of interfaces. The first type is the medium dependent interface(MDI) used by terminal equipment such as network card. Refer to Table 5-6. The second typeis the MDI-X used by network equipment. Refer to Table 5-7.

Straight through cables are used between MDI and MDI-X interfaces, and crossover cables areused between MDI interfaces or between MDI-X interfaces. The only difference between thetwo network cables are the connections.The ETH and ETH-HUB ports on IDU support MDI/MDI-X auto-sensing. Thus, both straightthrough cables and crossover cables can be used between these ports and the MDI/MDI-Xinterfaces.

A microwave link protection system composed of one working channel andone protection channel. Two ODUs and two IF boards are used at each endof a microwave link.

AATPC Automatic Transmit Power Control. A method of adjusting the transmit

power based on fading of the transmit signal detected at the receiver. BBit error An error occurs to some bits in the digital code stream after being received,

judged, and regenerated, thus damaging the quality of the transmittedinformation.

DDC-C The power system with the GND and PGND connected.DC-I The power system with the GND and PGND isolated.Digitalmodulation

Digital modulation controls the changes in amplitude, phase, and frequencyof the carrier based on the changes in the baseband digital signal, so that theinformation can be transmitted by the carrier. The digital modulation methodsof the OptiX RTN 600 include QPSK, 16QAM, and 128QAM.

Equalization A method of avoiding selective fading of frequencies. Equalization cancompensate for the changes of amplitude frequency caused by frequencyselective fading.

FFD Frequency Diversity. Two or more microwave frequencies with certain

frequency space are used to transmit/receive the same signal and selection isthen performed between the two signals to ease the impact of fading.

FEC Forward Error Correction. A bit error correction technology that adds to thepayload at the transmit end the correction information based on which the biterrors generated during transmission are corrected at the receive end.

demultiplexing, and IF processing for services.IF Intermediate Frequency. IF is the transitional frequency between the

frequencies of a modulated signal and an RF signal.IF board A board that processes microwave services. N Non-primarystation

amplification for RF signals.Orderwire Orderwire is a channel that provides voice communications among operation

engineers or maintenance engineers of different stations. PPDH Plesiosynchronous Digital Hierarchy. A multiplexing scheme of bit stuffing

and byte interleaving. It multiplexes the minimum rate 64 kit/s into the 2Mbit/s, 34 Mbit/s, 140 Mbit/s and 565 Mbit/s rates.
