There are two methods for mounting the ODU and the antenna: direct mounting and separatemounting.

l The direct mounting method is generally adopted when a small- or medium-diameter andsingle-polarized antenna is used. In this situation, if one ODU is configured for one antenna,the ODU is directly mounted at the back of the antenna. If two ODUs are configured forone antenna, an RF signal combiner/splitter (hence referred to as a hybrid coupler) mustbe mounted to connect the ODUs to the antenna. Figure 1-3 illustrates the direct mountingmethod.The direct mounting method can also be adopted when a small- or medium-diameter anddual-polarized antenna is used. Two ODUs are mounted onto an antenna using anorthomode transducer (OMT). The method for installing an OMT is similar to that forinstalling a hybrid coupler.

Figure 1-3 Direct mounting

l The separate mounting method is adopted when a large- or medium-diameter and single-

or dual-polarized antenna is used. Figure 1-4 shows the separate mounting method. In thissituation, a hybrid coupler can be mounted (two ODUs share one feed boom).

Figure 1-4 Separate mounting

NOTE

The OptiX RTN 950 provides an antenna solution that covers the entire frequency band, and supportssingle-polarized antennas and dual-polarized antennas with diameters of 0.3 m to 3.7 m along with thecorresponding feeder system.

System Control and Communication Unit

The system control and communication unit consists of the CPU unit and logic control unit. Thesystem control and communication unit performs the following functions:

l The CPU unit controls and manages the other units on the board and collects alarms andperformance events using the control bus.

l The CPU unit controls and manages the other boards in the IDU and collects alarms andperformance events using the control bus.



21

l The CPU unit controls and manages the ODU by transmitting the ODU control signal tothe SMODEM unit in the IF board over the control bus in the backplane.

l The CPU unit processes network management messages in DCCs using the logic controlunit.

l The CPU unit communicates with the NMS by its Ethernet NM port and NE cascadingport.

l The CPU unit implements software loading by reading information from the CF card withthe bus.

l The CPU unit monitors and manages an outdoor cabinet by reading the outdoor cabinetmonitoring signal with the bus.

l The logic control unit decodes the address read/write signals from the CPU unit and enablesFPGA loading.

l The logic control unit cross-connects the overheads between the auxiliary interface unit,the CPU unit, and other boards. This helps to achieve the following purposes:– Adding or dropping DCC information processed by the CPU unit– Adding or dropping orderwire and asynchronous data services– Exchanging the orderwire bytes, DCC bytes, and K bytes between different lines

l The system control and communication unit on a CST board communicates with the systemcontrol and communication unit on the paired CST board by carrying FE signals over thecommunication bus in the backplane. In this manner, 1+1 hot backup between paired boardsis achieved.

Cross-Connect UnitThe cross-connect unit grooms services over the entire system using the higher order cross-connect module and the lower order cross-connect module. Figure 3-5 shows the functionalblock diagram of the cross-connect unit.

Figure 3-5 Functional block diagram of the cross-connect unit

Source TDMservice unit Higher order

cross-connectmoduleHOXC

Lower ordercross-connect

Sink TDMservice unit

The source TDM service unit transmits VC-4 signals to the higher order cross-connect moduleover VC-4 buses. If the VC-4 signals carry only VC-4 services, the higher order cross-connectmodule processes the VC-4 signals and then transmits the signals to the sink TDM service unit.



22

If the VC-4 signals include VC-12 or VC-3 services, the higher order cross-connect modulegrooms the VC-12 or VC-3 services to the lower order cross-connect module. The lower ordercross-connect module processes the VC-12 or VC-3 services and then transmits the servicesback to the higher order cross-connect module. The higher order cross-connect module processesthe services and then transmits the services to the sink TDM service unit.

Clock Unitl The clock unit selects an appropriate clock source from external clock sources or service

clock sources at service ports based on clock priorities. Locking the clock source by meansof the phase-locked loop, the clock unit provides the system clock.

l The clock units on the main and standby boards transmit clock signals to each other.

Power Supply Unit

The power supply unit performs the following functions:

l Combines and then converts the two -48 V power inputs into the power supply required bythe chips of the other units on the local board.

l Combines and then converts the two -48 V power inputs into the +3.3 V power supplyrequired by the other boards in the IDU.

l Combines and then converts the two -48 V power inputs into the +12 V power supplyrequired by the fan.

NOTE

The NMS/COM port and the EXT port are equivalent to two ports on a hub. This means that no externalEthernet link should be configured between the two ports during the networking process; otherwise, anEthernet loop will be formed. As a result, a broadcast storm is generated on the network, leading to repeatedresetting of NEs.

3.3.5 DIP Switches and CF CardThis board has a set of DIP switches and a pluggable CF (compact flash) card.

NE databases, system parameters (including NE-IP, NE-ID, and subnet mask), softwarepackages, and NE logs are stored on the CF card. After you press the CRV button on the systemcontrol, switching, and timing board and hold it for eight seconds, the data stored on the CF cardwill be loaded to the board. To synchronize the NE databases, system parameters, and NE logson the system control, switching, and timing board to the CF card, enable the regular backupfunction.

NOTE

The software packages on the CF card are synchronized with those on the system control, switching, and timingboard during package diffusion. Therefore, automatic backup mechanisms or manual operations are not neededto synchronize software packages on the system control, switching, and timing board and the CF card. If thesystem control, switching, and timing board and the CF card have different software packages or data, theSWDL_PKGVER_MM alarm will be reported.

The NMS/COM port and the EXT port are equivalent to two ports on a hub. This means that no externalEthernet link should be configured between the two ports during the networking process; otherwise, anEthernet loop will be formed. As a result, a broadcast storm is generated on the network, leading to repeatedresetting of NEs.

Figure 3-16 shows the two common incorrect connections.

Button Name Description

CF RCV CF configuration restorationbutton

After this button is pressed and held foreight seconds, the board automaticallyrestores the NE database from the CFcard.

RST Warm reset button After this button is pressed, a warmreset is performed on the board.

Latches

There is a latch near each ejector lever on the front panel of the board. When removing a board,you can rotate the ejector levers only after pushing the latches to the middle positions. In addition,rotating the ejector levers triggers the tact switch on the board and then triggers working/protection switching.

3.4.4 DIP Switches and CF CardThis board has a set of DIP switches and a pluggable CF (compact flash) card.

NE databases, system parameters (including NE-IP, NE-ID, and subnet mask), softwarepackages, and NE logs are stored on the CF card. After you press the CRV button on the systemcontrol, switching, and timing board and hold it for eight seconds, the data stored on the CF cardwill be loaded to the board. To synchronize the NE databases, system parameters, and NE logson the system control, switching, and timing board to the CF card, enable the regular backupfunction.

NOTE

The software packages on the CF card are synchronized with those on the system control, switching, and timingboard during package diffusion. Therefore, automatic backup mechanisms or manual operations are not neededto synchronize software packages on the system control, switching, and timing board and the CF card. If thesystem control, switching, and timing board and the CF card have different software packages or data, theSWDL_PKGVER_MM alarm will be reported.

234

Two types of interfaces use RJ45 connectors, which are medium dependent interfaces (MDIs)and MDI-Xs. MDIs are used by terminal equipment, for example, network card. The pinassignments for MDIs are provided in Table 5-8. MDI-Xs are used by network equipment. Thepin assignments for MDI-Xs are provided in Table 5-9.

Table 5-8 Pin assignments for MDIs











Table 5-9 Pin assignments for MDI-Xs










235






Straight-through cables are used between MDIs and MDI-Xs, and crossover cables are usedbetween MDIs or between MDI-Xs. The only difference between straight-through cables andcrossover cables is with regard to the pin assignment.

The NMS/COM port, NE cascading port, and Ethernet electrical service ports of the OptiX RTN950 support the MDI, MDI-X, and auto-MDI/MDI-X modes. Straight-through cables andcrossover cables can be used to connect the NMS/COM port, EXT port, and Ethernet electricalservice ports to MDIs or MDI-Xs.

When a nodeon the ring detects oneor more new faults, itstarts up the hold-offtimer if the presethold-off time is set to avalue that is not 0.During the hold-offtime, the fault is notreported to trigger anERPS. When the hold-off timer times out, thenode checks the linkstatus regardlesswhether the fault thattriggers the startup ofthe timer exists. If thefault exists, the nodereports it to trigger anERPS.

As aresult, the outdated R-APS packets may existon the ring network.After a node on thering receives theoutdated R-APSpackets, an incorrectERPS may occur. TheERPS guard timer is anR-APS timer used forpreventing a node onthe ring from receivingoutdated R-APSpackets. When a faultynode on the ringdetects that theswitching condition iscleared, the node startsup the guard timer andstarts to forward the R-APS (NR) packets.During this period, theR-APS packetsreceived by the nodeare discarded. Thereceived R-APSpackets are forwardedonly after the time ofthe guard timerexpires.



482


WTR Time(mm:ss) 5 to 12, in step of 1 5 l This parameterindicates or specifiesthe WTR time of theWRT timer in the caseof ERPS protection.

When a nodeon the ring detects oneor more new faults, itstarts up the hold-offtimer if the presethold-off time is set to avalue that is not 0.During the hold-offtime, the fault is notreported to trigger anERPS. When the hold-off timer times out, thenode checks the linkstatus regardlesswhether the fault thattriggers the startup ofthe timer exists. If thefault exists, the nodereports it to trigger anERPS.

As aresult, the outdated R-APS packets may existon the ring network.After a node on thering receives theoutdated R-APSpackets, an incorrectERPS may occur. TheERPS guard timer is anR-APS timer used forpreventing a node onthe ring from receivingoutdated R-APSpackets. When a faultynode on the ringdetects that theswitching condition iscleared, the node startsup the guard timer andstarts to forward the R-APS (NR) packets.During this period, theR-APS packetsreceived by the nodeare discarded. Thereceived R-APSpackets are forwardedonly after the time ofthe guard timerexpires.



607


WTR Time(mm:ss) 5 to 12, in step of 1 5 l This parameterindicates or specifiesthe WTR time of theWRT timer in the caseof ERPS protection.

l The WTR time refersto the duration fromthe time when theworking channel isrestored to the timewhen the switching isreleased. When theworking channel isrestored, the WTRtimer of the RPLowner starts up. Inaddition, a signal thatindicates the operationof the WTR timer iscontinuously output inthe timing process.When the WTR timertimes out and noswitching request of ahigher priority isreceived, the signalindicating theoperation of the WTRtimer is nottransmitted.

LAG Type StaticManual

Static l Static: A static LAG is created by theuser. To add or delete a member port, youneed to run the Link AggregationControl Protocol (LACP) protocol. In astatic LAG, a port can be in selected,standby, or unselected state. By runningthe LACP protocol, devices exchangeaggregation information so that theyshare the same aggregation information.

l Manual: A manual LAG is created by theuser. When you add or delete a memberport, you need not run the LACPprotocol. In a manual LAG, a port can bein the UP or DOWN state. The systemdetermines whether to aggregate a portaccording to its physical state (UP orDOWN), working mode, and rate.

Load Sharing SharingNon-Sharing

Sharing l Sharing: In a sharing LAG, all memberports always share the traffic load. Thesharing mode can improve bandwidthutilization on a link. When the memberports are changed or some member portsfail, the traffic load of each member portis automatically re-allocated.

l Non-Sharing: In a non-sharing LAG,only one member port carries the trafficload and the other member ports are inStandby state. Actually, a non-sharingLAG works in hot-standby mode. Whenthe active port fails, the system selects astandby port to substitute for the failedport, thus preventing a link failure.

Sharing Mode IP Sharing ModeMAC Sharing Mode

IP Sharing Mode You can set this parameter only when LoadSharing is Sharing.

Revertive Mode RevertiveNon-Revertive

Revertive l You can set this parameter only whenLoad Sharing is Non-Sharing.

Scheduling Mode SPWRR

Queue 1: WRRQueue 2: WRRQueue 3: WRRQueue 4: WRRQueue 5: WRRQueue 6: WRRQueue 7: WRRQueue 8: SP

By default, queue 8 (with the CoS priorityof 7) of the EMS6 board is the SP queue, andqueues 1-7 (with the respective CoS priorityof 0-6) are the WRR queues and theirweights are in the proportion of1:2:8:16:32:64.The scheduling principles of the SP+WRRare as follows:l A port immediately transmits the packets

in the SP queue and can transmit thepackets in the WRR queue only when nopackets exist in the SP queue.

l If multiple SP queues exist on a port, theport compares the SP queues accordingto their priorities (queue 8 has the highestpriority and queue 1 has the lowestpriority).

l According to the fixed weight value, youcan allocate the time slice to each WRRqueue. Then, the port transmits thepackets in the corresponding WRRqueue in each time slice. If a WRR queuein a time slice does not contain anypackets, the WRR queue removes thistime slice and then transmits the packetsin the corresponding WRR queue in thenext time slice.

Weight An integer rangingfrom 1 to 64

IfGigabit Ethernet is, however, deployed to be the private bandwidth system with a bridge(switch) or a router as the center, it gives full play to the performance and the bandwidth.In the network structure, Gigabit Ethernet uses full duplex links that are private, causingthe length of the links to be sufficient for backbone applications in a building and campus.

Root alarm An alarm directly caused by anomaly events or faults in the network. Some lower-levelalarms always accompany a root alarm.

route A route is the path that network traffic takes from its source to its destination. In a TCP/IP network, each IP packet is routed independently. Routes can change dynamically.

route table A mapping table that stores the relationship between the original address, destinationaddress, short message (SM) protocol type and account. The SMSC delivers an SM tothe designated account according to the information set in the route table.

Routing InformationProtocol

A simple routing protocol that is part of the TCP/IP protocol suite. It determines a routebased on the smallest hop count between source and destination. RIP is a distance vectorprotocol that routinely broadcasts routing information to its neighboring routers and isknown to waste bandwidth.

routing table A table that stores and updates the locations (addresses) of network devices. Routersregularly share routing table information to be up to date. A router relies on thedestination address and on the information in the table that gives the possible routes--inhops or in number of jumps--between itself, intervening routers, and the destination.Routing tables are updated frequently as new information is available.

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 equipment located in adjacent regions and closelyrelated with one another, and it is indicated with a sub-network icon on a topologicalview. The U2000 supports multilevels of sub-networks. A sub-network planning canbetter the organization of a network view.

Synchronization StatusMessage

A message that carries quality levels of timing signals on a synchronous timing link.Nodes on an SDH network and a synchronization network acquire upstream clockinformation through this message. Then the nodes can perform proper operations on theirclocks, such as tracing, switching, or converting to holdoff, and forward thesynchronization information to downstream nodes.

synchronous digitalhierarchy

A transmission scheme that follows ITU-T G.707, G.708, and G.709. It defines thetransmission 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 used only for signals. SDH is suitablefor the fiber communication system with high speed and a large capacity since it usessynchronous multiplexing and flexible mapping structure.

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.

A STM-N is the information structure used to support section layer connections in SDH.See ITU-T Recommendation G. 707 for STM modules of order 1, 4, 16 and 64.

T

tail drop A type of QoS. When a queue within a network router reaches its maximum length,packet drops can occur. When a packet drop occurs, connection-based protocols such asTCP slow down their transmission rates in an attempt to let queued packets be serviced,thereby letting the queue empty. This is also known as tail drop because packets aredropped from the input end (tail) of the queue.

Tail drop A congestion management mechanism, in which packets arrive later are discarded whenthe queue is full. This policy of discarding packets may result in network-widesynchronization due to the TCP slow startup mechanism.

A multiplexing technology. TDM divides the sampling cycle of a channel into time slots(TSn, n=0, 1, 2, 3, ...), and the sampling value codes of multiple signals engross timeslots in a certain order, forming multiple multiplexing digital signals to be transmittedover one channel.

time to live A technique used in best-effort delivery systems to prevent packets that loop endlessly.The TTL is set by the sender to the maximum time the packet is allowed to be in thenetwork.

The purpose is to prevent the congestion caused byunbalanced loads.

traffic engineeringdatabase

TEDB is the abbreviation of the traffic engineering database. MPLS TE needs to knowthe features of the dynamic TE of every links by expanding the current IGP, which usesthe link state algorithm, such as OSPF and IS-IS. The expanded OSPF and IS-IS containsome TE features, such as the link bandwidth and color. The maximum reservedbandwidth of the link and the unreserved bandwidth of every link with priority are ratherimportant. Every router collects the information about TE of every links in its area andgenerates TE DataBase. TEDB is the base of forming the dynamic TE path in the MPLSTE network.

Traffic shaping It is a way of controlling the network traffic from a computer to optimize or guaranteethe performance and minimize the delay. It actively adjusts the output speed of trafficin the scenario that the traffic matches network resources provided by the lower layerdevices, avoiding packet loss and congestion.
