4 Crocus SHDSL G703 Chapter 1User manualIntroducing the Crocus SHDSL G7031.1 Crocus SHDSL G703 featuresThe Crocus SHDSL G.703 (Single-Pair High Bit Rate Digital Subscriber Line) is a manageable basebandmodem offering full 2,3 Mbps duplex transmission over unconditioned unshielded twisted-pair cable.A dedicated 2-pair version offers the possibility to extend the reach to longer distances or higher speeds(up to 4.6 Mbps). For extreme long distances, the equipment can fall back to a lower transmission rate,offering reduced speeds on the Fractional E1 (FE1) operation. The equipment is based on the TC-PAM(Trellis Coded Pulse Amplitude Modulation) modulation, which guarantees higher speeds and longerloop performance. It also guarantees spectral compatibility with legacy and ADSL transmission systemsin the same cable bundle. The unit can be used in a point-to-point configuration, or can be used with acentral solution based on card-nest 4 (CN4) or the Telindus 2300. The Crocus SHDSL G.703 is availableas a locally or remotely powered (RP) unit. The remotely powered unit can also be locally powered at -48VDC directly or by 230Vac through an external power adapter. The unit is designed for integration intodemanding network environments and can be controlled by the complete set of network maintenanceand management tools.Summarised:• data transmission rates up to 2304 kbps (Crocus SHDSL G703 1 pair version) or even 4608 kbps(Crocus SHDSL G703 2 pair version)• extended management possibilities for configuration and inspection purposes• easy self-test and link-test functions• flash memory for easy software updating• different powering possibilities (115/230 Vac or -48 Vdc)• central site high density card nest solution.

6 Crocus SHDSL G703 Chapter 1User manualIntroducing the Crocus SHDSL G7031.3 Identifying the Crocus SHDSL G703 non-RP and RP versionThis manual describes both the Crocus SHDSL and Crocus SHDSL RP version. The front panel of theCrocus SHDSL (i.e. the non-RP version) and the Crocus SHDSL RP are the same. However, you canidentify them by looking at the back panel:VersionBack panelCrocus SHDSL G703 • 9 Vdc power connector• RJ45/BNCCrocus SHDSL G703 RP • 9 Vdc power connector• 48 Vdc power connector• RJ45/BNCFor a view of the back panels of both Crocus SHDSL versions, refer to 2.6 - Connecting the CrocusSHDSL TT on page 18.The Crocus SHDSL G703 (i.e. the non-RP version) can not be powered by remote power. Only use theCrocus SHDSL G703 RP version in a remote power setup.

Crocus SHDSL G703 Chapter 1 7User manualIntroducing the Crocus SHDSL G7031.4 Power back-offThe Crocus SHDSL G703 features power back-off. Power back-off is a part of the ITU-T G.991.2 SHDSLrecommendation. It reduces the maximum transmit power level if the line conditions are sufficiently goodto operate at a lower transmit level.Power back-off is performed by default (no configuration attribute). During the ITU-T G.994.1 handshake,the two sides of the line mutually agree on the transmit level. The transmit level is loweredbetween 0 and 6 dB in steps of 1dB.Important remarkWhen 2 devices are connected point to point using the lowest speeds, an attenuation is always neededto get into data state, despite the power back-off mechanism. Connecting the devices with a cable of 1meter for instance will not work.For the lowest speeds, a minimum distance of 2 kilometers (simulated or not) is required between thedevices.

Crocus SHDSL G703 Chapter 2 25User manualInstalling and connecting the Crocus SHDSL G7032.7.1 What is remote power (RP)?Remote powering means that a local modem (RP source modem) supplies operational power over theline to a remote modem (RP sink modem). Remote powering is in accordance with the ITU-T recommendationK.15.The RP sink modem typically is dual powered. This means that it is either powered by a local power supplyor by remote power over the line.

Therefore the LTU or central modem can not be configured in slave-receive clocking.• In case you have two Crocus SHDSL G703 2P (2 pair) versions, you can not use two Crocus SHDSLRepeater 1P (1 pair) version on each line pair. This does not work.For more information on the Crocus SHDSL Repeater, refer to the Crocus SHDSL Repeater manual.Maximum 8 Crocus SHDSL repeaters can be used on a link.

Crocus SHDSL G703 Chapter 5 57User manualStep-by-step configuration5.2.1 What is EOC?SHDSL devices can communicate with each other through the Embedded Operations Channel (EOC).For instance the Crocus SHDSL G703 can send the following types of EOC requests:• inventory, to get information (manufacturer, release, etc.) about the remote SHDSL device,• enable / disable network loop-backs on the remote SHDSL device,• retrieve statistics or failure information (SNR Margin, loop attenuation, number of CRC errors, etc.).The EOC messages are defined in G.991.2 to provide interoperability.5.2.2 The EOC handling attributecrocusShdslTtRpG703/line/eocHandlingUse the eocHandling attribute to define the handling of the EOC messages.The eocHandling attribute has the following values:Default:noneRange: enumerated, see belowValuenonediscoveryinventoryinfoalarmConfigurationDescriptionThe Crocus SHDSL G703 does not send EOC requests. However, the CrocusSHDSL G703 will answer on EOC requests coming from other SHDSL devices.The Crocus SHDSL G703 "scans" the SHDSL line. For every device it discovers,it adds an object to the containment tree. Refer to 5.2.3 - Discovering devices onthe SHDSL line on page 58.Then the Crocus SHDSL G703 retrieves information from these devices and displaysit in the corresponding objects. Exactly which information is retrieveddepends on the setting of the eocHandling attribute. Refer to 5.2.4 - EOC retrievedinformation on page 58.Also in this case the Crocus SHDSL G703 "scans" the SHDSL line, adds theobjects to the containment tree and retrieves information from the devices. Referto 5.2.3 - Discovering devices on the SHDSL line on page 58 and 5.2.4 - EOCretrieved information on page 58.Additionally, the central 1 SHDSL device forces the remote 2 SHDSL device andany intermediary repeater to use the link alarm thresholds lineAttenuation and signal-Noise as configured on the central device in the attribute line/linkAlarmThresholds. Inother words, the settings of the lineAttenuation and signalNoise on the central deviceoverrule those of the remote device and repeaters.Refer to crocusShdslTtRpG703/line/linkAlarmThresholds on page 115 for moreinformation.1. The central device is the device on which the channel attribute is set to central.2. The remote device is the device on which the channel attribute is set to remote.

58 Crocus SHDSL G703 Chapter 5User manualStep-by-step configuration5.2.3 Discovering devices on the SHDSL lineWhen you change the eocHandling attribute from none to any other value, the Crocus SHDSL G703 starts"scanning" the SHDSL line in order to determine which devices are present between itself and its remotecounterpart. When the scan is finished, some new objects are added to the containment tree on thesame level as the line object:• If one or more repeaters are present on the SHDSL line, a repeater[ ] object is added for every repeater.• For the remote counterpart, an end object is added.The new objects are not added instantaneously. It can take up to 5 minutes before these objects appearin the containment tree.For example, suppose you have a link with a Crocus SHDSL G703 as central device, a Telindus 1421SHDSL Router as remote device and one Crocus SHDSL G703 Repeater in between. Suppose you setthe eocHandling attribute to discovery. In that case the one repeater[ ] object and an end object is added tothe containment tree as can be seen in the screenshot:The first discovered repeater will have id 3, the second one will have id 4, etc.5.2.4 EOC retrieved informationAs said before, exactly which information is retrieved from the remote SHDSL device(s) through the EOCchannel depends on the setting of the eocHandling attribute.This section gives an overview in which case which information is retrieved:• EOC status information, refer to EOC status information.• EOC performance information, refer to EOC performance information.• EOC alarm information, refer to EOC alarm information.

In this mode, all possible clocking modescan be selected.In this mode the SHDSL frame does not have stuffing bits to compensate clockdeviations towards the user interface clock. In this case only internal and slavereceive clocking is allowed. What is more, internal clocking is only allowed at oneside of the link (e.g. the central side) and slave receive clocking at the other side(e.g. the remote side).Synchronous mode is the typical timing mode in DSLAM set-ups.• If you set the framing attribute to framed, then the Crocus SHDSL G703 always operates in plesiochronousmode regardless of the setting of the timingMode attribute.• You always have to work in the same timing mode at both sides of the link. In other words:- central: synchronous - remote: synchronous → allowed- central: plesiochronous - remote: plesiochronous → allowed- central: synchronous - remote: plesiochronous or vice versa → not allowed• For compatibility with other SHDSL devices, setting this attribute to the correct value might be essential.Refer to 5.13 - Crocus SHDSL G703 compatibility with other SHDSL devices on page 96.

66 Crocus SHDSL G703 Chapter 5User manualStep-by-step configuration5.5.1 Important remark on the minimum line pair speedIf you configure the minimum line pair speed (i.e. you set the minLinePairSpeed attribute to any value differentfrom ), then only one master clock is allowed in the system.In other words, only the following clocking combinations are allowed:One sideinternalexternalexternalstationOther sidealways slave receiveslave receiveexternal (provided the application on both sides use the same network clock)station or slave receiveExecuting an ET test on both sides will not work in case both sides change their clocking modes to internal!ExampleThe following is a perfectly legal set-up as long as the minimum line pair speed is not configured (i.e.minLinePairSpeed = ):• clocking = internalPreferred• speed = 640kbps• minLinePairSpeed = • clocking = internalPreferred• speed = 640kbps• minLinePairSpeed = However, if you set the minimum line pair speed to a value higher than the user speed, then the SHDSLline operates in slotted E1 mode. In that case, only one master clock is allowed in the system. So youwould have to change the configuration to, for example:• clocking = internalPreferred• speed = 640kbps• minLinePairSpeed = 1024kbps• clocking = slaveRcvPreferred• speed = 640kbps• minLinePairSpeed = 1024kbps

Crocus SHDSL G703 Chapter 5 67User manualStep-by-step configuration5.5.2 The minimum line pair speed attributeAlso see 5.5.1 - Important remark on the minimum line pair speed on page 66.The location of the minimum line pair speed attribute in the Crocus SHDSL G703 containment tree is:crocusShdslTtRpG703/line/minLinePairSpeedUse the minLinePairSpeed attribute to determine what the minimum speed onthe line pair has to be when the Crocus SHDSL G703 trains.The purpose of this is:Default:Range: 192kbps up to2048kbps (in steps of64kbps)• To be able to set the line speed independently from the user speed. This allows easy upgrading to ahigher user speed.• To be able to use less than 3 time slots (or 6 time slots on a 2 pair version).

68 Crocus SHDSL G703 Chapter 5User manualStep-by-step configurationThe minLinePairSpeed attribute has the following values:Value192kbps up to2048kbps (in stepsof 64kbps)DescriptionThe line speed follows the user speed.For example, if the user speed is set to 640 kbps (speed(2P) = 640kbps), then thespeed on the line pair equals …• 640 kbps in case of a Crocus SHDSL G703 1P (1 pair) version.• 320 kbps on each line pair in case of a Crocus SHDSL G703 2P (2 pair) version.The line speed no longer follows the user speed. The line trains on the speed asset with the minLinePairSpeed attribute.For example, if the user speed is set to 640 kbps (speed(2P) = 640kbps) and the minimumline speed is set to 1024 kbps (minLinePairSpeed = 1024kbps), then the speedon the line pair(s) equals 1024 kbps. (On a Crocus SHDSL G703 1P (1 pair) versionthis is also the total line speed. On a Crocus SHDSL G703 2P (2 pair) version,however, the total line speed then is 2048 kbps since the minLinePairSpeed attributesets, as the name implies, the minimum speed on the line pair.)RemarkNote that the maximum total line speed that you can set using the minLinePair-Speed attribute is 2048 kbps. So for a Crocus SHDSL G703 1P (1 pair) versionyou can set the minLinePairSpeed attribute to its maximum value (being 2048kbps). For a Crocus SHDSL G703 2P (2 pair) version, however, you can only setit up to 1024 kbps (which is a total line speed of 2048 kbps). If you neverthelessset the minLinePairSpeed attribute to a value higher than 1024 kbps, then a messageis displayed in the messages table and the Crocus SHDSL G703 2P continuesto operate with a total line speed of 2048 kbps.• Make sure that you set the minLinePairSpeed attribute to the same value on both the central and remoteSHDSL device.• When using the minLinePairSpeed attribute on the central or remote SHDSL device, the user speed ofthe other device may not be set to autospeed.

Crocus SHDSL G703 Chapter 5 69User manualStep-by-step configuration5.5.3 Purpose of the minimum line pair speedEasily upgrading the user speedYou could determine in advance what the maximum speed is that can be achieved on the line (e.g. 1024kbps) and set the minimum line pair speed to this value (e.g. minLinePairSpeed = 1024kbps). Suppose thecustomer initially wants 256 kbps. So you set the user speed to 256 kbps (speed(2P) = 256kbps). Now whenthe customer decides he wants a higher user speed (e.g. 640kbps), then you can easily change the userspeed to this higher speed (e.g. speed(2P) = 640kbps) without first having to determine again whether theline can handle this speed. What is more, the line does not have to retrain after you changed the userspeed. So you can perform user speed upgrades in an easy, cost-efficient way.Low speed operation - compatibility with other SHDSL devicesIf you want to use only 1 or 2 time slots (or 2 or 4 time slots in case of a 2 pair version), then you haveto set the minimum line pair speed to 192 kbps (minLinePairSpeed = 192kbps). This to insure correct time slotsynchronisation on both sides.Low speed operation - 2 time slots and 2 applicationsIf you want to use only 2 time slots (or 4 time slots in case of a 2 pair version) and each time slot carriesthe data of a different application, then you also have to set the minimum line pair speed to 192 kbps(minLinePairSpeed = 192kbps). This to insure that on the remote side the data is separated correctly.The reason is the following:• In case you select only 2 time slots (or 4 time slots in case of a 2 pair version) but you do not configurethe minimum line pair speed (minLinePairSpeed = ), then the SHDSL line operates in Nx64 mode(refer to crocusShdslTtRpG703/line/framerType on page 138 for more information on this mode).Since in this case the user data has become a continuous bit stream on the SHDSL line, it is almostimpossible to correctly separate the data from the two different applications at the remote end.• In case you select only 2 time slots (or 4 time slots in case of a 2 pair version) but you configure theminimum line pair speed to be 192 kbps (minLinePairSpeed = 192kbps), then the SHDSL line operates inslotted E1 mode (refer to crocusShdslTtRpG703/line/framerType on page 138 for more informationon this mode). Since in this case the user data is also put in time slots on the SHDSL line, it is perfectlypossible to separate the data from the two different applications at the remote end.

Else you might get unexpectedresults (e.g. devices that do not answer to polling, answer of several devices at once when pollingone device, etc.).• Once your network starts to become complex on management level (i.e. more than just in-line connectionsas depicted in Relative addressing on page 78), you are advised to use absolute addressinginstead of relative addressing (refer to Absolute addressing on page 78).In practice, it is best to use absolute addressing when you configure one of the attributes listed belowas follows:- ctrlPortProtocol attribute to management,- g703/saBits to anything else than transparent.• Changing the ctrlPortProtocol attribute causes the Crocus SHDSL G703 to reboot.• When sending management information to the three management interfaces (the line, the G703 interfaceusing SA bits, and the CTRL port), a problem may occur. Due to insufficient processing powerof the Crocus SHDSL G703, it could occur that a device connected to the Crocus SHDSL G703 cannotbe reached anymore (on management level).Conclusion is that sending management information to the three management interfaces simultaneouslyis not possible, due to lack of processing power of the Crocus SHDSL G703.

By doing so (and by setting the appropriate attributes as seen on theprevious page), the management data can pass from one device to another, not only over the line butalso over the E1 interface.Special points of interest in this network are:• On TT 2 and TT 4, you have to set the saBits to o10Management or o10-pathManagement. By doing so,you are able to forward management data over the E1 interface connection between TT 2 and TT 4.On TT 3, however, you have to set the saBits to transparent, because on CV 1 internalDmm is enabled.Else you have two possible paths towards the management system for CV 1 and all modems afterCV 1:- one path through TT 3,- one path through TT4.In this case, you might get unexpected results. Therefore, make sure there is only one path towards themanagement system!• You have to enable internalDmm on CV 1, because the management data has to be able to pass frommodem B to modem A. By doing so, you are able to forward management data over the …- line to TT 3,- E1 interface connection between CV 1 modem A and CV 2 modem A.• On modem A of both CV 1 and CV 2, you have to set the saBits to o10Management or o10-pathManagement.By doing so, you are able to forward management data over the E1 interface connection betweenmodem A of CV 1 and CV 2. On modem B of both CV 1 and CV 2, however, you have to set the saBitsto transparent, because on CV 1 and CV 2 internalDmm is enabled. Else you have two possible pathstowards the management system. Make sure there is only one path towards the management system!• You have to enable internalDmm on CV 2, because the management data has to be able to pass frommodem A to modem B. By doing so, you are able to forward management data over the line to bothCV 3 modem A and B.• You have to disable internalDmm on CV 3, because else you have two possible paths towards the managementsystem for CV 3. E.g. if you would enable internalDmm, then modem A could contact the managementsystem …- either over the line and then through CV 2 modem A etc.- or through CV 3 modem B, over the line and then through CV2 modem B etc.In this case, you might get unexpected results.

It influences the relationshipbetween the line clock and the user interface clock.Use the timingMode attribute to set the timing mode.The Crocus SHDSL G703 has two clock sources:• one takes care of the clocking on the SHDSL line.• one takes care of the clocking on the modular user interface.Using the timingMode attribute you can define whether these two clocks run independent from each other(i.e. plesiochronous mode) or whether they are "coupled" with each other (i.e. synchronous mode).The timingMode attribute has the following values:Default:pleisiochronousRange: pleisiochronous / synchronousValueplesiochronoussynchronousDescriptionIn this mode each SHDSL frame has 0 or 4 stuffing bits to compensate clock deviationstowards the user interface clock. In this mode, all possible clocking modescan be selected.In this mode the SHDSL frame does not have stuffing bits to compensate clockdeviations towards the user interface clock. In this case only internal and slavereceive clocking is allowed. What is more, internal clocking is only allowed at oneside of the link (e.g. the central side) and slave receive clocking at the other side(e.g. the remote side).Synchronous mode is the typical timing mode in DSLAM setups.• You always have to work in the same timing mode at both sides of the link.

The background block error ratio is the ratio of background block errors tototal blocks during a 2 hour time interval. The count of total blocks excludes allblocks during severely errored seconds. So if the background block error ratio …• exceeds this value within a 2 hour period4, then the bBErrRatioExceeded alarm israised.• drops below this value within a 2 hour period, then the bBErrRatioExceeded alarmis cleared.1. The central device is the device on which the channel attribute is set to central.2. The remote device is the device on which the channel attribute is set to remote.3. The 2 hour periods run synchronous with the 2 hour periods of the line/h2Line performanceattribute. Because alarms are raised or cleared within 2 hour periods, there is a delay in thealarm status. For example, suppose that in the first minute of a 2 hour period the errSecRatioExceededvalue is exceeded, then the errSecRatioExceeded alarm is raised. The alarm stays on forthe remainder of the 2 hour period. The alarm is only cleared if also in the next 2 hour periodthe errSecRatioExceeded value is not exceeded.

The status attribute maxLinePairSpeed displays the highest possiblespeed that could be achieved on the line pair(s) during the training cycle.In case you configure a fixed user speed (i.e. you set the configuration attributespeed(2P) to a fixed value) and a minimum line pair speed (using the configurationattribute minLinePairSpeed) and the user speed is lower than the line speed, then theline trains at the configured line speed.So in this case, the status attribute min-LinePairSpeed displays a speed that is equal to the configured minimum line pairspeed. What is more, the status attributes minLinePairSpeed and maxLinePairSpeed displaythe same speed.RemarkNote that this only applies when the configured user speed is lower than the configuredline speed. In case the configured user speed is higher than the configuredline speed, the user speed (fixed) situation applies. See above.user speed(auto) + linespeedIn case you configure an auto user speed (i.e. you set the configuration attributespeed(2P) to auto) and a minimum line pair speed (using the configuration attributeminLinePairSpeed), then during the training cycle the lowest (which is the minimumline pair speed) and highest possible line speed is determined. Then the line trainsat the highest possible speed and this becomes the user speed.So in this case, thestatus attribute minLinePairSpeed displays a speed that is equal to the configuredminimum line pair speed. The status attribute maxLinePairSpeed displays the highestpossible speed that could be achieved on the line pair(s) during the training cycle.

138 Crocus SHDSL G703 Chapter 7Reference manualStatus attributescrocusShdslTtRpG703/line/framerTypeThis attribute displays which type of framing is used on the SHDSL line: Nx64 or slotted E1.The line of the Crocus SHDSL G703 can operate in two modes: Nx64 or slotted E1. These modes arenot directly user configurable (i.e. there is no attribute with which you can select these modes), butdepending on which interface is used, which user/line speed is chosen, etc. the Crocus SHDSL G703will select one of these modes.ModeNx64slotted E1DescriptionIn this mode the data on the SHDSL line is a continuous bit stream with a speedof N x 64 kbps, where N ranges from 1 up to 36 (or from 2 up to 72 in case of aCrocus SHDSL G703 2 pair version). So the line speed ranges from 64 kbps up to2304 kbps (or 128 kbps up to 4608 kbps in case of a Crocus SHDSL G703 2 pairversion).In this mode the data on the SHDSL line is put in N x 64 kbps time slots (similar toframed data on a G.703 interface), where N ranges from 3 up to 32 (or from 6 upto 64 in case of a Crocus SHDSL G703 2 pair version).

These statistics can be useful to locate and solve the problem.• By collecting performance information, an operator can keep track of the global performance of thenetwork, e.g. network bottlenecks can be traced, etc.Before discussing the performance attributes of the Crocus SHDSL G703 in detail, some general informationon the performance attributes of the Crocus SHDSL G703 is given.The following gives an overview of this section.• 8.2.1 - Introducing the performance timing on page 161• 8.2.2 - Introducing the performance terms on page 162

Crocus SHDSL G703 Chapter 8 161Reference manualPerformance attributes8.2.1 Introducing the performance timingThe following table explains the performance information timing.Performancetiming2 hours,24hours,7 dayssince bootDescriptionThe performance information is accumulated during a certain time span, called aperiod. After a period, the accumulated performance information is written into abuffer. Then a new period starts. An interval contains several periods:• To cover a 2 hours interval, 8 periods of 15 minutes are kept.• To cover a 24 hours interval, 12 periods of 2 hours are kept.• To cover a 7 days interval, 7 periods of 24 hours are kept.The buffer in which the information is stored, is a circular buffer. I.e. every period(15 minutes, 2 hours or 24 hours) the most recent measured and calculated valuesare added, and the oldest values are lost.In this case, the performance information is kept since the latest cold boot of theCrocus SHDSL G703. This can be considered as a performance information summary.The Crocus SHDSL G703 does not contain a real-time clock, therefore time information is related to itsinternal clock. To allow you to situate the time intervals in the real time, the sysUpTime attribute is returnedtogether with the performance information. It reflects the time since the latest cold boot of the CrocusSHDSL G703.Only the available performance information is displayed. If the interrogation happens shortly after boot,no values are displayed. For example for the 24 hours intervals, the new performance information isavailable only when a complete time span (i.e. 2 hours) has elapsed.

182 Crocus SHDSL G703 Chapter 9Reference manualAlarm attributesThis section explains the attributes that allow you to configure the alarm behaviour of the Crocus SHDSLG703. These configuration alarm attributes are:crocusShdslTtRpG703/…/alarmMaskUse this attribute to mask or unmask the alarms of an object. This determines whether an active alarm …• is forwarded to the central management system (e.g. TMA Element Management or HP OpenView)or not.• causes a change of colour in the subsystem picture (refer to Chapter 10 - TMA subsystem picture ofthe Crocus SHDSL G703 on page 201).The alarms in the alarmMask attribute have the following values:ValueenableddisabledIs the active alarm being forwarded to the central management system?Does the active alarm cause a change of colour in the subsystem picture?Yes. So the alarm is unmasked.No. So the alarm is masked.Alarms are always seen in the alarmInfo alarm attribute of an object, regardless of the masking of thealarm. I.e. even if an alarm is set to disabled in the alarmMask of an object, if the alarm condition is fulfilledthen the alarm will be set to on in the alarmInfo of that object. However, because this alarm is disabled itwill not be sent to the central management system.Only the most important alarms are unmasked (i.e. enabled) by default. All other alarms are masked (i.e.disabled).crocusShdslTtRpG703/…/alarmLevelUse this attribute to assign a priority level to each alarm of the corresponding object. The alarm levelrange goes from 0 to 254, where 0 is the lowest and 254 is the highest priority level.The alarmLevel of an unmasked, active alarm is sent to the totalAlarmLevel of the top objectcrocusShdslTtRpG703.

These are:crocusShdslTtRpG703/totalAlarmLevelThis attribute is only present in the top object of the containment tree of the Crocus SHDSL G703,crocusShdslTtRpG703.It displays the priority level of an unmasked, active alarm. When several alarms are generated at thesame time, the highest priority level is shown. If the alarm levels are set in a structured manner, one lookat the totalAlarmLevel attribute enables the operator to make a quick estimation of the problem.The value of the totalAlarmLevel attribute is also communicated to the central management system (e.g.TMA Element Management or HP OpenView) where it determines the colour of the icon. This colour isan indication of the severity of the alarm.crocusShdslTtRpG703/…/alarmInfoThe alarmInfo contains the actual alarm information of the corresponding object. This information isupdated each time there is a change in the status of an alarm within this object.The alarmInfo attributes are:AttributediscriminatorcurrentAlarmspreviousAlarmsalarmMaskalarmLevelDisplays for the corresponding object …the total number of alarm status changes in this object since the last cold boot.the current alarm status of this object.the previous alarm status of this object.the alarmMask as configured in the Configuration group.the alarmLevel as configured in the Configuration group.
