Radio Work Mode

The IF board can operate in the following seven radio work modes.

E3 16QAM 14 (13.75)

STM-1 128QAM 28 (27.5)

NOTE

l The channel spacings 13.75 MHz and 27.5 MHz are applied to the 18 GHz frequency band.

l The channel spacings listed in the table are the minimum channel spacings supported by the OptiXRTN 600. The channel spacings larger than the values are also supported.

Radio Link ID

The radio Link ID is an identification of the microwave link. The transmit end continuouslysends the radio Link ID byte, so that the receive end can learn that the transmit end is in a constantconnection state. If the receive end detects a mismatch of the radio Link ID, the MW_LIM alarmis reported on the corresponding IF port.

Wayside Service Attributes

When the IF board works in the STM-1 mode, one wayside service can be transported by radio.The following are the two parameters of wayside services:

l 2M wayside Enable Status




Issue 07 (2010-05-25)

This parameter determines whether the NE enables the 2M wayside service. By default,the 2M wayside service is disabled.

l 2M wayside input board

This parameter determines through which PXC the wayside service is accessed.

ATPC Attributes

ATPC is a technology that automatically adjusts the transmit power of the transmitter accordingto the attenuation of the received signal level (RSL) at the receive end. The following are theparameters of ATPC:

l ATPC enable status

This parameter determines whether the NE enables the ATPC function to control thetransmit power of the transmitter. By default, the ATPC function is disabled.

l ATPC upper threshold

When the RSL at the receive end is higher than this parameter, the receive end notifies thetransmit end of reducing the transmit power by using the ATPC overhead in the microwaveframe. The decrement depends on the value of the ATPC adjustment parameter.

l ATPC lower threshold

When the RSL at the receive end is lower than this parameter, the receive end notifies thetransmit end of increasing the transmit power by using the ATPC overhead in themicrowave frame. The increment depends on the value of the ATPC adjustment parameter.

l ATPC adjustment

This parameter determines the decrement/increment of an ATPC adjustment.

l Automatic ATPC threshold setting

This parameter can be set to Enabled or Disabled. When this parameter is set to Enabled,the preset ATPC upper threshold and ATPC lower threshold do not take effect. Theequipment sets the ATPC thresholds automatically according to the IF modulation scheme.When this parameter is set to Disabled, the preset ATPC upper threshold and ATPC lowerthreshold are used.

NOTE

ATPC adjustment cannot exceed the range of the ODU transmit power.

J1 Byte

The board supports four modes, which are as follows:

l Single-byte mode

l 16-byte mode with CRC

l 16-byte mode without CRC

l 64-byte mode

By default, the board does not monitor the received J1 byte, that is, the J1 byte to be received isset to the disabled mode. The J1 byte to be sent is a 16-byte string with CRC. The first byte isautomatically created and the following 15 bytes are the ASCII code "HuaWei SBS ". Thelatter five characters of the string are blank spaces.

3.4.6 NM Configuration ReferenceIn the NM system, the board parameters that you may frequently set are as follows: the radiowork mode, radio Link ID, wayside service attributes, ATPC attributes, XPIC attribute, and J1byte.

Radio Work ModeThe IFX supports only one radio work mode.

Table 3-16 Radio work mode


STM-1 128QAM 28 (27.5)

NOTE

l 27.5 MHz is the channel spacing of the 18 GHz frequency band.

l The channel spacing described in the table is the minimum channel spacing supported by the equipment.The channel spacing larger than the value is also supported.

Radio Link IDThe radio Link ID is an identification of the microwave link. The transmit end continuouslysends the radio Link ID byte, so that the receive end can learn that the transmit end is in a constantconnection state. If the receive end detects a mismatch of the radio Link ID, the MW_LIM alarmis reported on the corresponding IF port.

Wayside Service AttributesWhen the IF board works in the STM-1 mode, one wayside service can be transported on radio.The following are the two parameters of wayside services:

l 2M wayside Enable StatusThis parameter determines whether the NE enables the 2M wayside service. By default,the 2M wayside service is disabled.

l 2M wayside input boardThis parameter determines through which PXC the wayside service is accessed.

ATPC AttributesATPC is a technology that automatically adjusts the transmit power of the transmitter accordingto the attenuation of the RSL at the receive end. The following are the parameters of ATPC:

l ATPC enable statusThis parameter determines whether the NE enables the ATPC function to control thetransmit power of the transmitter. By default, the ATPC function is disabled.



3-27

l ATPC upper threshold

When the RSL at the receive end is higher than this parameter, the receive end notifies thetransmit end of reducing the transmit power by using the ATPC overhead in the microwaveframe. The decrement depends on the value of the ATPC adjustment parameter.

l ATPC lower threshold

When the RSL at the receive end is lower than this parameter, the receive end notifies thetransmit end of increasing the transmit power by using the ATPC overhead in themicrowave frame. The increment depends on the value of the ATPC adjustment parameter.

l ATPC adjustment

This parameter determines the decrement/increment of an ATPC adjustment.

l Automatic ATPC threshold setting

This parameter can be set to Enabled or Disabled. When this parameter is set to Enabled,the preset ATPC upper threshold and ATPC lower threshold do not take effect. Theequipment sets the ATPC thresholds automatically according to the IF modulation scheme.When this parameter is set to Disabled, the preset ATPC upper threshold and ATPC lowerthreshold are used.

NOTE


XPIC Attributes

The XPIC enabled parameter can be set to enabled or disabled.

l When the XPIC function is enabled, the IFX splits the received IF signal, outputs one signalto the XPIC OUT port, and performs XPIC by using the reference IF signal from the XPICIN port.

l When the XPIC function is disabled, the XPIC IN port and XPIC OUT port must be loopedback by using an XPIC cable.

3.7 SL4The SL4 is an SDH single-port STM-4 board.

3.7.1 Version DescriptionThe functional version of the SL4 is SL61.



3-53

3.7.2 Functions and FeaturesThe SL4 receives and transmits 1xSTM-4 optical signals.

Optical Interface Specificationsl The SL4 provides S-4.1, L-4.1, or L-4.2 optical interfaces.

l The optical interface complies with ITU-T G.957.

Optical Module Specificationsl Adopts the SFP optical modules and provides LC fiber connectors.

l Supports the setting of turning on or shutting down the laser.

l Supports the querying of the technical parameters of the optical modules.

l Supports the reporting of the performance events related to the transmit optical power andreceive optical power.

l Supports the automatic laser shutdown (ALS) function.

NOTEThe ALS functions as follows:

1. When the optical module detects the R_LOS alarm at the receive port and the alarm persists for 500ms, the corresponding laser at the transmit port is automatically shut down.

2. The laser starts to launch an alternative laser pulse. The light is emitted for 2s after a 60s interval.

3. When the R_LOS alarm is cleared, the laser returns to the normal working state and emits lightcontinuously.

Overhead Processingl Processes the regenerator section overheads of the STM-4 signals.

l Processes the multiplex section overheads of the STM-4 signals.

l Processes the higher order path overheads of the STM-4 signals.

l Supports the setting and querying of the J0/J1/C2 byte.

NOTE

Higher order path overheads are processed in two modes. The first mode is called the pass-through mode.The path overheads are detected in the receive direction only and the overhead values are not modified.The second mode is called the termination mode. When the path overheads are detected in the receivedirection, the transmit direction resets the overheads according to the default value of the board. By default,the board adopts the pass-through mode.

Pointer Processing

Processes AU pointers.

Protection Processingl Supports the monitoring and reporting of the status of the working and protection channels

in an SNCP group.l Supports the monitoring and reporting of the status of the working and protection channels

in a two-fiber bidirectional MSP ring.

3.12.6 NM Configuration ReferenceIn the NM system, the board parameters that you may frequently set are as follows: SDHparameters, Ethernet external port parameters, and Ethernet internal port parameters.

SDH Parameters

The J1 and J2 bytes are the SDH parameters that you may frequently set.

l J1 byteThe board supports four modes, which are as follows:– Single-byte mode

– 16-byte mode with CRC

– 16-byte mode without CRC

– 64-byte mode

By default, the board does not monitor the received J1 byte, that is, the J1 byte to be receivedis set to the disable mode. The J1 byte to be sent is a 16-byte string with CRC. The firstbyte is automatically created and the following 15 bytes are the ASCII code "HuaWeiSBS ". The latter five characters of the string are blank spaces.

l J2 byteThe board supports two modes, which are as follows:– Single-byte mode

– 16-byte mode with CRC

By default, the board does not monitor the received J2 byte, that is, the J2 byte to be receivedis set to the disable mode. The J2 byte to be sent is a 16-byte string with CRC. The firstbyte is automatically created and the following 15 bytes are the ASCII code "HuaWeiSBS ". The latter five characters of the string are blank spaces.

Ethernet External Port Parameters

The EFT4 provides four external ports, that is, PORT1 to PORT4. The parameters that you mayfrequently set for every external port are as follows: port enabled, working mode, maximumframe length, and flow control.

l Port enabled




Issue 07 (2010-05-25)

This parameter is used to control the enabled/disabled status of Ethernet ports. By default,this parameter is set to disabled.

l Working modeThe board supports three working modes as follows:– Auto-negotiation

– 10M full-duplex

– 100M full-duplex

By default, the working mode is auto-negotiation. When the equipment on the oppositeside adopts the auto-negotiation, 10M full-duplex, or 100M full-duplex mode, the localequipment should be set to the same working mode. When the equipment on the oppositeside adopts 10M half-duplex or 100M half-duplex, the local equipment should be set to theauto-negotiation mode.

l Maximum frame lengthThe board supports a maximum frame length that ranges from 1518 to 1535 bytes. Bydefault, the maximum frame length is 1522 bytes. This parameter should not be set smallerthan the maximum length of the Ethernet frame transmitted from the equipment on theopposite side. Usually, the default value can meet the requirement.

l Flow controlThe board supports three flow control modes as follows:– Disabled mode

– Autonegotiation flow control mode

– Non-autonegotiation flow control mode

By default, the flow control mode is set to the disabled mode.The autonegotiation flow control mode can be as follows:– Enable dissymmetric flow control

The port can transmit PAUSE frames during congestion but cannot process the receivedPAUSE frames.

– Enable symmetric flow controlThe port can transmit PAUSE frames during congestion and process the receivedPAUSE frames.

– Enable symmetric/dissymmetric flow controlThe port adopts the symmetric flow control mode or dissymmetric flow control modeaccording to the auto-negotiation result.

The non-autonegotiation flow control mode can be as follows:– Send only


– Receive onlyThe port can process the received PAUSE frames but cannot transmit PAUSE framesduring congestion.




3-103

The flow control parameter should be set depending on that of the equipment on the oppositeside.

Ethernet Internal Port ParametersThe EFT4 provides four internal ports, that is, VCTURNK1 to VCTRUNK4, corresponding toPORT1 to PORT4 respectively. The parameters that you may frequently set for every internalport are as follows: encapsulation/mapping protocol, bound path, and LCAS.

l Encapsulation/Mapping protocolThe board supports three encapsulation/mapping protocols: GFP, HDLC, and LAPS. GFPis the default protocol. The protocol and related parameter settings should be the same asthe protocol and related parameter settings of the equipment on the opposite side.

l Bound pathAll the VC-3s in VC-4-1 and VC-4-2 can be bound to the VCTRUNK. The maximumnumber of bound paths is 6. All the VC-12s in VC-4-2 can also be bound to the VCTRUNK.The maximum number of bound paths is 63.

l LCASThe board supports the enabling/disabling of the LCAS function. By default, the LCASfunction is disabled. The enabling status and parameter settings of the LCAS functionshould be the same as the enabling status and parameter settings of the equipment on theopposite side.

3.13.7 NM Configuration ReferenceIn the NM system, the board parameters that you may frequently set are as follows: SDHparameters, Ethernet external port parameters, and Ethernet internal port parameters.

SDH Parameters

The J1 and J2 bytes are the SDH parameters that you may frequently set.

l J1 byte

The board supports the following four modes: single-byte mode, 16-byte mode with CRC,16-byte mode without CRC, and 64-byte mode. By default, the board does not monitor thereceived J1 byte, that is, the J1 byte to be received is set to the disable mode. The J1 byteto be sent is a 16-byte string with CRC. The first byte is automatically created and the



3-115

following 15 bytes are the ASCII code "HuaWei SBS " (five blank spaces after thecharacter string).

l J2 byteThe board supports the following two modes: single-byte mode and 16-byte mode withCRC. By default, the board does not monitor the received J2 byte, that is, the J2 byte to bereceived is set to the disable mode. The J2 byte to be sent is a 16-byte string with CRC.The first byte is automatically created and the following 15 bytes are the ASCII code"HuaWei SBS " (five blank spaces after the character string).

Ethernet External Port Parameters

The EMS6 provides six external ports, that is, PORT1 to PORT6. The parameters that you mayfrequently set for every external port are as follows:

l Basic attributes

l TAG attributes

l Network attributes

l Flow control

l Advanced attributes

The basic attributes are applicable to all Ethernet services and include the following threeparameters: port enabled, working mode, and maximum frame length.

l Port enabledThis parameter is used to control the enabled/disabled status of Ethernet ports. By default,this parameter is set to disabled.

l Working mode– The FE interface supports 10M full-duplex, 10M half-duplex, 100M full-duplex, 100M

half-duplex, and auto-negotiation working modes.– The GE electrical interface supports 10M full-duplex, 10M half-duplex, 100M full-

duplex, 100M half-duplex, 1000M full-duplex, and auto-negotiation working modes.– The GE optical interface supports 1000M full-duplex and auto-negotiation working

modes.Set the working mode of the equipment on the local side depending on the working modeof the equipment on the opposite side. For the setting suggestions, refer to the OptiX RTN600 Radio Transmission System Feature Description.

l Maximum frame lengthThe board supports a maximum frame length that ranges from 1518 to 9600 bytes. Bydefault, the maximum frame length is 1522 bytes. This parameter should not be set smallerthan the maximum length of the Ethernet frame transmitted from the equipment on theopposite side. Usually, the default value can meet the requirement.

The TAG attributes are used to specify whether and how the VLAN services are processed. TheTAG attributes include the following parameters:

l TAGThe TAG parameter is used to identify the type of packets. The TAG parameter can be setto TAG aware, access, and hybrid. By default, the TAG parameter is set to TAG aware.The principles for processing packets are as follows:




Issue 07 (2010-05-25)

– Tag aware: The port allows only the packets that contain a TAG to pass, and discardsthe packets that do not contain a TAG.

– Access: The port allows only the packets that do not contain a TAG to pass, and discardsthe packets that contain a TAG.

– Hybrid: The port processes both the packets that contain a TAG and the packets that donot contain a TAG. In the case of the packets that do not contain a TAG, the port addsa TAG to the packets according to the VLAN ID of the port. In the case of the packetsthat contain a TAG, the port receives the packets without change.

l Ingress checkThis parameter is used to specify whether the TAG of a packet is checked. This parametercan be set to enabled or disabled. By default, this parameter is set to enabled. If thisparameter is set to disabled, the TAG flag is invalid. In this case, the port transparentlytransmits the received packet.

l Default VLAN IDWhen the TAG parameter is set to access or hybrid, you can set a default VLAN ID for theport. The default VLAN ID ranges from 1 to 4095. By default, the default VLAN ID is 1.

The network attributes are used to specify whether and how the QinQ services are processed.The network attribute of each port can be set to UNI, C-aware, or S-aware. By default, thenetwork attribute of a port is UNI. The principles for processing packets are as follows:

l UNI: The port processes the TAG attributes of the 802.1Q-compliant packets. The UNIport has the tag aware, access, and hybrid attributes.

l C-aware: The port does not process the TAG attributes of the 802.1Q-compliant packets.The port considers that the accessed packet does not contain an S-VLAN tag.

l S-aware: The port does not process the TAG attributes of the 802.1Q-compliant packets.The port considers that the accessed packet contain a S-VLAN tag.

The board supports the following flow control modes:autonegotiation flow control mode andnon-autonegotiation flow control mode. By default, the flow control mode is set to the disabledmode. The flow control parameter should be set depending on the flow control parameter of theequipment on the opposite side.

l The autonegotiation flow control mode can be as follows:– Disabled

The port does not work in the autonegotiation flow control mode.– Enable dissymmetric flow control



– Enable symmetric/dissymmetric flow controlThe port adopts the symmetric flow control mode or dissymmetric flow control modeaccording to the auto-negotiation result.

l The non-autonegotiation flow control mode can be as follows:– Disabled

The port does not work in the non-autonegotiation flow control mode.



3-117

– Send onlyThe port can transmit PAUSE frames during congestion but cannot process the receivedPAUSE frames.

– Receive onlyThe port can process the received PAUSE frames but cannot transmit PAUSE framesduring congestion.


The advanced attributes are used to set the broadcast packet suppression function. The broadcastpacket suppression function prevents broadcast packets from affecting normal data services andalso effectively prevents network attacks. The following parameters need to be set for thebroadcast packet suppression function: Enabling Broadcast Packet Suppression and BroadcastPacket Suppression Threshold.l The Enabling Broadcast Packet Suppression parameter can be set to Enabled or Disabled.

– When the Enabling Broadcast Packet Suppression parameter is set to Disabled, the portdoes not use the broadcast packet suppression function.

– When the Enabling Broadcast Packet Suppression parameter is set to Enabled, the portdiscards the received broadcast packets when the traffic of the received broadcastpackets exceeds the set broadcast packet suppression threshold.

l The Broadcast Packet Suppression Threshold parameter can be set to a value in the rangefrom 1 to 10. When this parameter is set to N, the port discards the received broadcastpackets when the ratio of the received broadcast packets to the total packets exceedsNx10%.

Ethernet Internal Port ParametersThe EMS6 provides eight internal ports, that is, VCTURNK1 to VCTRUNK8. The parametersthat you may frequently set for every internal port are as follows: encapsulation/mappingprotocol, bound path, and LCAS.

l The TAG attributes are used to specify whether and how the VLAN services are processed.The TAG attributes include the following parameters:– TAG

The TAG parameter is used to identify the type of packets. The TAG parameter can beset to TAG aware, access, and hybrid. By default, the TAG parameter is set to TAGaware. The principles for processing packets are as follows:– Tag aware: The port allows only the packets that contain a TAG to pass, and discards

the packets that do not contain a TAG.– Access: The port allows only the packets that do not contain a TAG to pass, and

discards the packets that contain a TAG.– Hybrid: The port processes both the packets that contain a TAG and the packets that

do not contain a TAG. In the case of the packets that do not contain a TAG, the portadds a TAG to the packets according to the VLAN ID of the port. In the case of thepackets that contain a TAG, the port receives the packets without change.

– Ingress checkThis parameter is used to specify whether the TAG of a packet is checked. Thisparameter can be set to enabled or disabled. By default, this parameter is set to enabled.




Issue 07 (2010-05-25)

If this parameter is set to disabled, the TAG flag is invalid. In this case, the porttransparently transmits the received packet.

– Default VLAN IDWhen the TAG parameter is set to access or hybrid, you can set a default VLAN ID forthe port. The default VLAN ID ranges from 1 to 4095. By default, the default VLANID is 1.

l Encapsulation/Mapping protocolThe board supports three encapsulation/mapping protocols: GFP, HDLC, and LAPS. GFPis the default protocol. The protocol and related parameter settings should be the same asthe protocol and related parameter settings of the equipment on the opposite side.

l The network attributes are used to specify whether and how the QinQ services areprocessed. The network attribute of each port can be set to UNI, C-aware, or S-aware. Bydefault, the network attribute of a port is UNI. The principles for processing packets are asfollows:– UNI: The port processes the TAG attributes of the 802.1Q-compliant packets. The UNI

port has the tag aware, access, and hybrid attributes.– C-aware: The port does not process the TAG attributes of the 802.1Q-compliant packets.

The port considers that the accessed packet does not contain an S-VLAN tag.– S-aware: The port does not process the TAG attributes of the 802.1Q-compliant packets.

The port considers that the accessed packet contain a S-VLAN tag.l Bound path

All the VC-3s in VC-4-1 and VC-4-2 can be bound to the VCTRUNK. The maximumnumber of bound paths is 6. All the VC-12s in VC-4-2 can also be bound to the VCTRUNK.The maximum number of bound paths is 63.

l LCASThe board supports the enabling/disabling of the LCAS function. By default, the LCASfunction is disabled. The enabling status and parameter settings of the LCAS functionshould be the same as the enabling status and parameter settings of the equipment on theopposite side.

External Clock Unit

In the receive direction, the external clock unit accesses one 2 MHz or 2 Mbit/s signal. If thesignal accessed is a wayside service signal, it is multiplexed into a 2M timeslot of an 8M overheadsignal and then sent to the SCC. If the signal accessed is a clock signal, it is sent to the clockunit.

In the transmit direction, to output the external clock, the unit receives an external clock signalfrom the clock unit. To output the wayside service signal, the unit demultiplexes the waysideservice signal from the 8M overhead signal.

Clock Unit

The clock unit detects and selects the external clock source or the service clock source fromservice boards. Through the phase-locked loop, the unit outputs the system clock and frameheaders of service signals and overhead signals for other units on the PXC and also other boards.

Cross-Connect Unit

The cross-connect unit is a three-level cross-connect matrix. The first level and the third levelare space division cross-connect matrixes that support VC-4 cross-connection only, with a cross-connect capacity of 16x16 VC-4s. The first level is called forward cross-connection and the thirdlevel is called backward cross-connection. The second level is a time division matrix thatsupports VC-4/VC-3/VC-12 cross-connection, with the cross-connect capacity equivalent to16x16 VC-4s. It is called lower order cross-connection.

The lower order cross-connect matrix is the core of a cross-connect unit. The forward andbackward cross-connect matrixes are used to improve the speed at which the cross-connect unitimplements service protection switching.

Power UnitThe power unit processes the input -48 V/-60 V power as follows:

1. Uses a protection circuit to protect the board from very high input current.2. Uses a protection circuit to protect the board from reverse polar connection of the input

power.3. Performs EMI filtering for the input current and detects whether the input current is very

high or very low.4. Distributes one power input to the -48 V power bus in the backplane, to supply -48 V power

to the SCC and IF boards.5. Uses a DC/AC power module to convert the other power input into +3.3 V power and then

sends it to the +3.3 V power bus in the backplane, to supply +3.3 V power to the otherboards.

The power unit also supplies power to the chips on the PXC.

Logic Control UnitThe board is directly controlled by the CPU of the SCC. The CPU issues configuration data andquerying commands to the various units of the board through the control bus. The commandresponse reported by the units inside the board, and the alarms and performance events arereported to the CPU also through the control bus.

NOTEAn SCC integrates an EOW subboard which occupies the logical slot 21.

3.15.7 NM Configuration ReferenceIn the NM system, the board parameters you may frequently set are as follows: the NE ID/IPaddress, orderwire interface parameters, synchronous data interface parameters, andasynchronous data interface parameters.

NE IDThe NE ID is a 24-bit hexadecimal number, which is used to identify the NE in ECCcommunication. The higher 8 bits of an NE ID are called the subnet ID, or the extended ID,whereas the lower 16 bits are called the basic ID. For example, for the NE ID 0x090001, "9" isthe subnet ID or extended ID and "1" is the basic ID.

By default, the NE ID is 0x09BFF0, with the subnet ID or extended ID as "9" and the basic IDas "49136".

NE IP AddressIP addresses are used and thus are valid only in TCP/IP communication.

By default, the NE IP address is 129.9.191.240.

Orderwire Interface ParametersOrderwire interface parameters include the orderwire phone number and the overhead byte usedto transmit orderwire.

The orderwire phone number is used to identify the phone in point-to-point addressing call. Thisparameter is set based on the orderwire planning. Generally, the orderwire phone number is setwith three digits.

The overhead byte used to transmit orderwire can be set to use the E1 or E2 byte, however, thissetting is invalid for SDH/PDH microwave links because the microwave system always uses amicrowave self-defined byte to transmit orderwire, regardless of whether the E1 or E2 byte isset.

Synchronous Data Interface ParametersIn the case of optical and electrical SDH lines, the synchronous data interface always uses theF1 byte. In the case of SDH/PDH microwave links, the synchronous data interface always usesa microwave self-defined byte.



3-141

Asynchronous Interface ParametersAsynchronous interface parameters include the asynchronous data interface type and theoverhead byte used to transmit asynchronous data.

The asynchronous data interface type is RS-232.

The overhead byte used to transmit asynchronous data can be set to any byte of Serial 1 to Serial4, as shown in Figure 3-70. This setting is, however, invalid for SDH/PDH microwave linksbecause the microwave system always uses a microwave self-defined byte to transmit orderwire,regardless of which serial byte is set.

5 Cables

About This Chapter

This section describes the purpose, appearance, and connections of various cables of the IDU610 and the IDU 620.

5.1 Power CableThe power cable connects the power supply system such as the power distribution box on thetop of the cabinet to the PXC of the IDU to carry the -48 V power into the OptiX RTN 600system.

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 XPIC CableThe XPIC cable is used to transmit the reference IF signal between the two IFX boards of theXPIC working group to realize the XPIC function.

5.5 Fiber JumperFiber jumpers are used to transmit optical signals. Fiber jumpers use LC/PC connectors at oneend to connect the OptiX RTN 600 optical interface boards. The connectors at the other end offiber jumpers depend on the type of optical interfaces of the equipment to be connected.

5.6 E1 CableThe E1 cables are available in four types: the E1 cables (with DB44 connectors) to the externalequipment, the E1 cables (with RJ-45 connectors) to the external equipment, the E1 cables tothe E1 panel, and the E1 transit cables.

5.7 External Clock Cable/Wayside Service Cable/STM-1e CableExternal clock cables, wayside service cables, and STM-1e cables use the same type of coaxialcables. This type of coaxial cable uses the SMB connector at one end to connect the PXC, SLE/SDE or PL3 board. The other end of the cable connects the DDF. The connectors are made asrequired by the site.

5.8 Auxiliary Interface Cable

OptiX RTN 600 Radio Transmission SystemIDU 610/620 Hardware Description 5 Cables


5-1

Auxiliary interface cables are used to input/output external alarms, synchronous interface data,and asynchronous interface data. The cable uses a DB26 connector at one end to connect to theALM/AUX interface on the SCC board. The other end of the cable is divided into four wires,which are wire W1, wire W2, wire W3, and wire W4. Wire W4 is terminated with one DB37connector and is connected to the external alarm equipment through an alarm transfer cable.Wire W2 is terminated with one DB9 connector and is connected to the equipment that is usedto transmit asynchronous data through a serial port cable. Wire W1 is also terminated with oneDB9 connector but the DB9 connector is reserved for future use. Wire W3 is not terminated witha connector and is used to transmit synchronous data.

5.9 External Alarm Transit CableExternal alarm transit cables are used to transit external alarm data. The cable uses the DB37connector at one end to connect the external alarm and asynchronous interface cable. The otherend of the cable connects external alarm equipment. The connectors are made as required by thesite. The external alarm transit cable transits two alarm outputs and six alarm inputs.

5.10 Serial Port CableSerial port cables are used for the management and maintenance of the OptiX RTN 600. Thecable uses the DB9 connectors at both ends, one for connecting the COM interface of the SCCboard, the other for connecting the computer, NM serial, or modem. Serial port cables are alsoused to transit asynchronous data services. In this case, the cable connects the external alarmand asynchronous interface cable and the equipment that transmits asynchronous data.

5.11 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 SCC boardIDU 605 and the otherend connects the interface of the orderwire phone set.

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

The XPIC cable is an RG316 cable with SMA connectors at both ends. One end of the XPICcable is connected to the XPIC IN port of one IFX board of an XPIC working group, and theother end of the XPIC cable is connected to the XPIC OUT port of the other IFX board of thesame XPIC working group.

When the XPIC function of an IFX board is disabled, use an XPIC cable to connect the XPICIN port and XPIC OUT port of the IFX board to loop back signals.

The XPIC cable is available in the following two types:

l XPIC cable using angle connectors: The XPIC cable using angle connectors is very long,and is used to connect the two IFX boards in the horizontal direction, for example, the IFXboards in slots 5 and 6 or the IFX boards in slots 7 and 8.

l XPIC cable using straight connectors: The XPIC cable using straight connectors is veryshort, and is used to connect the two IFX boards in the vertical direction, for example, theIFX boards in slots 5 and 7 or the IFX boards in slots 6 and 8. The XPIC cable using straightconnectors is also used to connect the XPIC IN port and XPIC OUT port of the same IFXboard to loop back signals.

5.6 E1 CableThe E1 cables are available in four types: the E1 cables (with DB44 connectors) to the externalequipment, the E1 cables (with RJ-45 connectors) to the external equipment, the E1 cables tothe E1 panel, and the E1 transit cables.

The following E1 cables can be delivered together with the equipment: the E1 cables (with DB44connectors) to the external equipment, the E1 cables (with RJ-45 connectors) to the externalequipment, the E1 cables to the E1 panel, and the E1 transit cables. The E1 cables (with RJ-45connectors) to the external equipment need to be made on site by terminating network cableswith RJ-45 connectors. The description of the E1 cables (with RJ-45 connectors) to the externalequipment is not provided in this topic.

5.6.1 E1 cables (with DB44 connectors) to the external equipmentWhen the SL61PO1/PH1 board directly inputs/outputs E1 signals from/to the externalequipment, use this E1 cable to connect the SL61PO1/PH1 board to the external equipment. Usea DB44 connector at the end of the E1 cable that is near the SL61PO1/PH1 board. Make aconnector for the other end that is near 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, and one E1 cable transmits eight E1 signals. The 75-ohm coaxial cables are further categorized into 2x8 core cables and 1x16 core cables.

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 5-16. The second typeis the MDI-X used by network equipment. Refer to Table 5-17.

Table 5-16 Pin assignments of the MDI











Table 5-17 Pin assignments of the MDI-X











Issue 07 (2010-05-25)






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 the SCC board, the four FE ports on the EFT4 board and theGE/FE electrical ports on the EMS6 board support MDI/MDI-X auto-sensing. Thus, bothstraight through cables and crossover cables can be used between these ports and the MDI/MDI-X interfaces.

sub-network Sub-network is the logical entity in the transmission network and comprises a group ofnetwork management objects. The network that consists of a group of interconnected orcorrelated NEs, according to different functions. For example, protection subnet, clocksubnet and so on. A sub-network can contain NEs and other sub-networks. Generally, asub-network is used to contain the equipments which are located in adjacent regions andclosely related with one another, and it is indicated with a sub-network icon on atopological view. The U2000 supports multilevels of sub-networks. A sub-networkplanning can better the organization of a network view. On the one hand, the view spacecan be saved, on the other hand, it helps the network management personnel focus onthe equipments under their management.

SubNetworkConnection

A "transport entity" that transfers information across a subnetwork, it is formed by theassociation of "ports" on the boundary of the subnetwork.

SubNetworkConnection Protection

A working subnetwork connection is replaced by a protection subnetwork connection ifthe working subnetwork connection fails, or if its performance falls below a requiredlevel.

Synchronization StatusMessage

A message that is used to transmit the quality levels of timing signals on the synchronoustiming link. Through this message, the node clocks of the SDH network and thesynchronization network can aquire upper stream clock information, and the two performoperations on the corresponding clocks, such as tracing, switchover, or converting hold),and then forward the synchronization information of this node to down stream.

Synchronous DigitalHierarchy

SDH is a transmission scheme that follows ITU-T G.707, G.708, and G.709. It definesthe transmission features of digital signals such as frame structure, multiplexing mode,transmission rate level, and interface code. SDH is an important part of ISDN and B-ISDN. It interleaves the bytes of low-speed signals to multiplex the signals to high-speedcounterparts, and the line coding of scrambling is only used only for signals. SDH issuitable for the fiber communication system with high speed and a large capacity sinceit uses synchronous multiplexing and flexible mapping structure.

synchronous transportmodule

An STM is the information structure used to support section layer connections in theSDH. It consists of information payload and Section Overhead (SOH) information fieldsorganized in a block frame structure which repeats every 125 . The information is suitablyconditioned for serial transmission on the selected media at a rate which is synchronizedto the network. A basic STM is defined at 155 520 kbit/s. This is termed STM-1. Highercapacity STMs are formed at rates equivalent to N times this basic rate. STM capacitiesfor N = 4, N = 16 and N = 64 are defined; higher values are under consideration.

TelecommunicationManagement Network

The Telecommunications Management Network is a protocol model defined by ITU-Tfor managing open systems in a communications network.An architecture formanagement, including planning, provisioning, installation, maintenance, operation andadministration of telecommunications equipment, networks and services.

Time DivisionMultiplexing

It is a multiplexing technology. TDM divides the sampling cycle of a channel into timeslots (TSn, n=0, 1, 2, 3……), and the sampling value codes of multiple signals engrosstime slots in a certain order, forming multiple multiplexing digital signals to betransmitted over one channel.

TMN See Telecommunication Management Network

trail A type of transport entity, mainly engaged in transferring signals from the input of thetrail source to the output of the trail sink, and monitoring the integrality of the transferredsignals.

TransmissionControlProtocol

The protocol within TCP/IP that governs the breakup of data messages into packets tobe sent via IP (Internet Protocol), and the reassembly and verification of the completemessages from packets received by IP. A connection-oriented, reliable protocol (reliablein the sense of ensuring error-free delivery), TCP corresponds to the transport layer inthe ISO/OSI reference model.

User DatagramProtocol

A TCP/IP standard protocol that allows an application program on one device to send adatagram to an application program on another. User Datagram Protocol (UDP) uses IPto deliver datagrams. UDP provides application programs with the unreliableconnectionless packet delivery service. Thus, UDP messages can be lost, duplicated,delayed, or delivered out of order.UDP is used to try to transmit the data packet, that is,the destination device does not actively confirm whether the correct data packet isreceived.

User Network Interface A type of ATM Forum specification that defines an interoperability standard for theinterface between ATM-based products (a router or an ATM switch) located in a privatenetwork and the ATM switches located within the public carrier networks. Also used todescribe similar connections in Frame Relay networks.

Virtual Container A Virtual Container is the information structure used to support path layer connectionsin the SDH. It consists of information payload and path Overhead (POH) informationfields organized in a block frame structure which repeats every 125 or 500 μs.

Virtual Local AreaNetwork

A logical grouping of two or more nodes which are not necessarily on the same physicalnetwork segment but which share the same IP network number. This is often associatedwith switched Ethernet.

Virtual PrivateNetwork

The extension of a private network that encompasses encapsulated, encrypted, andauthenticated links across shared or public networks. VPN connections can provideremote access and routed connections to private networks over the Internet.
