About This Chapter

This section describes the purpose, appearance, and connections of various cables of the IDU605.

5.1 Power CableThe power cable connects the –48 V/–60 V power supply equipment such as the powerdistribution box on the top of the cabinet to the IDU 605 to carry the –48 V/–60 V power intothe OptiX RTN 600 system.

5.2 Protection Ground CableThe IDU, ODU, and E1 panel need to be grounded through their own protection ground cables.

5.3 IF JumperThe IF jumper is used to connect the ODU and IF cable. The IF jumper is used together withthe IF cable to transmit the IF signal between the ODU and the IDU, O&M signal, and -48 Vpower.

5.4 E1 CableThe E1 cable is available in two types. One type of E1 cable connects the IDU 605 to the externalequipment and the other type of E1 cable connects the IDU 605 to an E1 panel.

5.5 Orderwire LineThe orderwire line is used to connect orderwire phone sets. Both ends of the line use RJ-11connectors. One end connects the PHONE interface of the IDU 605 and the other end connectsthe interface of the orderwire phone set.

5.6 Network CableNetwork cables are used to connect Ethernet equipment. Both ends of a network cable use RJ-45connectors.

5.3 IF JumperThe IF jumper is used to connect the ODU and IF cable. The IF jumper is used together withthe IF cable to transmit the IF signal between the ODU and the IDU, O&M signal, and -48 Vpower.

The IF jumper is a 2 m RG223 cable. The IF jumper uses a type-N connector at one end toconnect to the IF cable, and a TNC connector at the other end to connect to the IF board.

5.4 E1 CableThe E1 cable is available in two types. One type of E1 cable connects the IDU 605 to the externalequipment and the other type of E1 cable connects the IDU 605 to an E1 panel.

5.4.1 From the PO1/PH1 Board to the External EquipmentWhen the IDU 605 directly inputs/outputs E1 signals from/to the external equipment, use thisE1 cable to connect the IDU 605 to the external equipment. Use a DB44 connector at the endof the E1 cable that is connected to the IDU 605. Make a connector for the other end that isconnected to the external equipment as required by the site.

The E1 cables that are connected to the external equipment are categorized into 75-ohm coaxialcables and 120-ohm twisted pair cables. One E1 cable can transmit eight E1 signals.

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.
