Human Services Department emphasized those carve-outs in newly issued regulations Wednesday." Notably, "HHS clarified that themandate doesn't apply to people who are eligible for Medicaid but live in states that don't take part in the law's Medicaid expansion."In a separate report, The Hill (1/30, Baker) "Healthwatch" blog writes, "The Obama administration took new steps Wednesdaytoward implementing the individual mandate in its signature healthcare law, downplaying the scope of the unpopular provision by stressingrules that allow exemptions from the requirement to purchase insurance." In announcing the exemptions, HHS said, "A principle inimplementing the individual shared responsibility provision is that the shared responsibility payment should not apply to any taxpayer forwhom coverage is unaffordable, who has other good cause for going without coverage, or who goes without coverage for only a shorttime."Modern Healthcare (1/31, Daly, Subscription Publication) reports that in a fact sheet accompanying the regulations, CMS said,"Both agencies' proposed regulations include rules that will ease implementation and help to ensure that the payment applies only to thelimited group of taxpayers who choose to spend a substantial period of time without coverage despite having ready access to affordablecoverage."From NAHUAccess NAHU's latest information on PPACA, including a timeline, through our Compliance Corner by clickinghere. This section of the website is constantly being updated, so be sure to check in often!| |Legislation and PolicyBill Would Eliminate Part Of ACA.The Washington Times (1/31, Howell) reports that Sens. Tom Coburn and Claire McCaskill on Wednesday announced "a bill todissolve part of President Obama's health care law that critics say skews some of the benefits to hospitals in Massachusetts, at theexpense of other states." The bill "would eliminate a money-shifting 'gimmick' that resulted from the use of rural hospitals as the wage floorfor Medicare reimbursements - a system that went askew because the Bay State's benchmark hospital happens to be on Nantucket, thewell-to-do island off the Atlantic Coast."Unions Push White House For Healthcare Subsidies.In a front-page article, the Wall Street Journal (1/31, A1, Adamy, Trottman, Subscription Publication) reports on the concerns somelabor unions have with the Affordable Care Act. Union leaders worry that some of its requirements will increase healthcare costs, giving anedge to smaller, non-unionized contractors. Because these contractors will likely have fewer than 50 employees, they will also not have topay a penalty for not providing health insurance, thus being able to provide a workforce at a lower cost. Unions are asking the ObamaAdministration to provide Federal subsidies to their lowest-paid members while also staying on their plans. The Administration is wary ofupsetting unions, a stout ally, but acknowledges the subsidies will also raise the cost of the new law..Medicare Adjusting Reimbursement For Dialysis.The Washington Post (1/31, Whoriskey) reports, "The Medicare system is recalculating how much it will reimburse hospitals andclinics for the drugs used to treat dialysis patients after federal auditors found recently that the program could save as much as $880million annually." An August analysis by the Post "showed that the government was overspending by hundreds of millions for just onegroup of those drugs." This occurred because the government was reimbursing for a dose that was higher than most people received.Dennis Cotter, president of the Medical Technology and Practice Patterns Institute, a research group, who called for price changes in2011, said, "It's good that Medicare is finally going to set a new, more accurate price. It's unfortunate that they could have done this twoyears ago. This has so far cost taxpayers more than $1.6 billion."Growing Healthcare Costs Straining Texas Budget.The AP (1/31, Tomlinson) reports, "Texas will use 'all the money that there is available to spend' in the state budget just paying thehealth care costs of the growing number of poor, disabled and elderly unless dramatic changes are made to the Medicaid system, the

It iscomposed of a number of objects that are ordered in a tree. This tree resembles aWindows directory structure:• it is also a levelled structure, with nodes which can be expanded or reduced• the containment tree objects can be compared with file folders• the objects contain attributes like file folders contain files.objectAn object represents a physical interface, an application or a combination of both.Each object has its own set of attributes.Example:The top object crocusDXC contains the sub-object crossConnect. This object containsall the attributes concerning the cross connections. E.g. the configuration attributecrossConnectTable.attributeAn attribute is a parameter related to a certain object. It has a certain value.Example:The object e1Interface[ ] contains the status attribute ifOperStatus, which has aspossible values up and down.valueAn attribute has a certain value which is …• changeable in case of a configuration attribute (provided you have write access)• read only in case of a status, performance and alarm attribute.Example:The configuration attribute stationClock can be set to the value enabled or disabled.structured valueSome attribute values contain underlying values: a structured value. These valuesare displayed in the structured value window. If an attribute contains structuredvalues then a bit string, or is displayed after the attribute.Example:The alarmLevel attribute contains a structured value which displays alarms and theircorresponding priority level.groupGroups assemble a set of attributes related by functionality. There are four groupsin TMA, which correspond with the four tabs in the attribute window:• configuration• status• performance• alarms.actionA group in combination with an object may have actions assigned to them. Theseactions are displayed in the action window.Example:The Activate Configuration action only appears when the object crocusDXC is selected incombination with the group Configuration.User manual 31

However, the Crocus DXC regularly checks the presence of a valid clock signal on theE1 interfaces (depending on the settings of the lineClocks attribute). If the Crocus DXC finds one(again), then it uses this as master clock.• A cross connection is only defined in one direction. In other words, transmit and receive data arealways cross connected on the same interface and time slots. I.e. in and out are symmetric.• If the signal on an E1 interface is used as master clock signal and if you execute an external loopbacktest on this E1 interface, then the Crocus DXC checks the presence of a valid clock signal on theremaining E1 interfaces (depending on the settings of the lineClocks attribute) or falls back to internalclocking mode.User manual 43

Step-by-step configurationCrocus DXC5.3.3 Clocking mode priorityDepending on which clocking modes are enabled (stationClock or lineClocks) the Crocus DXC always tries toselect a clocking mode with the highest priority. The clocking mode priority is as follows:PriorityClocking modeHighmediumlowstation clockingE1 interface clockinginternal clockingExampleSuppose the stationClock attribute is set to enabled and the lineClocks attribute is set to lines 1, 2, 3, 4. Thisresults in the following:PhaseAction1 The Crocus DXC tries to select the station clock.2 If no valid station clock signal is present, then the Crocus DXC scans the first four E1interfaces and tries to select a clock on one of these interfaces.3 If no valid clock signal is present on any of the first four E1 interfaces, then the CrocusDXC goes to internal clocking.However, the Crocus DXC regularly verifies all the different clocking possibilities. If theCrocus DXC detects it can select a clocking mode with a higher priority than the currentclocking mode, the Crocus DXC will do so.44 User manual

Crocus DXCStep-by-step configuration5.6 Configuring the management attributesThis section explains the management attributes of the Crocus DXC. These attributes allow you to makeall the devices in your network accessible for management from one central location.First this section gives you some rules of thumb and remarks concerning the management of the CrocusDXC in a network. Then it explains the attributes that have an impact on the management of the CrocusDXC. Finally, it gives an example of a network and how to configure the Crocus DXC to make itaccessible for the central management system.The following table gives an overview of this section:Section Title Page5.6.1 Rules of thumb and remarks concerning management 525.6.2 Using relative or absolute addressing 535.6.2 Selecting the purpose of the control connector 535.6.4 Configuring the SA-bits on an E1 interface 555.6.5 Example – management over the E1 interfaces 56User manual 51

Step-by-step configurationCrocus DXC5.6.1 Rules of thumb and remarks concerning managementThe following lists some rules of thumb concerning the management of Telindus devices in a network:• Make sure there is only one path towards the management system. Else you might get unexpectedresults (e.g. devices that do not answer to polling, answer of several devices at once when polling onedevice, etc.).• Once your network starts to become complex on management level (i.e. more than just in-lineconnections as depicted in Relative addressing on page 53), you are advised to use absoluteaddressing instead of relative addressing (refer to Absolute addressing on page 53).In practice, it is best to use absolute addressing when you configure one of the attributes listed belowas follows:− ctrlPortProtocol attribute to management,− e1Interface[ ]/saBits to anything else than transparent.• Changing the ctrlPortProtocol attribute causes the Crocus DXC to reboot.52 User manual

Crocus DXCStep-by-step configuration5.6.2 Using relative or absolute addressingIn order to connect with TMA to the Crocus DXC (refer to Section 4.1 - Starting a TMA session on theCrocus DXC), you can use two addressing schemes:Address typerelativeDescriptionThis type of addressing is meant for a network topology where the devices areconnected in-line on management level. I.e. with extended managementconnections between two devices.To enable relative addressing, no address has to be specified in the device. In otherwords, you can leave the cms2Address attribute at its default value, being 0.Relative addressingAn extended management connection is realised with a crossed cable between thecontrol connectors of the two Telindus devices. You also have to set thectrlPortProtocol attribute to the value management.absoluteThis type of addressing is meant for a network topology where the devices are notconnected in-line on management level. I.e. when there is a digital multipoint devicepresent (e.g. the Orchid DM).To enable absolute addressing, an address has to be specified in the device. Dothis using the cms2Address attribute. The absolute addressing range goes from 1 upto 65535. Refer to crocusDXC/management/cms2Address.Absolute addressingUser manual 53

Step-by-step configurationCrocus DXC5.6.3 Selecting the purpose of the control connectorcrocusDXC/management/ctrlPortProtocoldefault: consoleThe setting of the ctrlPortProtocol attribute depends on what purpose the control connector of the CrocusDXC has to serve. This is explained in the following table:ValuemanagementDescriptionSelect this value if you want to connect the control connector of the Crocus DXC to…• a management concentrator (e.g. the Orchid 1003 LAN or Telindus 1035 Orchid)for management purposes.• the control connector of another Telindus device using a crossed cable (i.e. theyare connected back-to-back) in order to create an extended management link.For more information on extended management links, refer to Relativeaddressing on page 53.When connecting the control connector of the Crocus DXC to a COM port of yourcomputer, you can still open a TMA session on the Crocus DXC. You can howevernot open a CLI or ATWIN session.consoleSelect this value if you want to connect the control connector of the Crocus DXC toa COM port of your computer in order to manage the Crocus DXC using TMA, CLIor ATWIN.54 User manual

Crocus DXCStep-by-step configuration5.6.4 Configuring the SA-bits on an E1 interfacecrocusDXC/e1Interface[ ]/saBitsdefault: pathManagementUse the saBits attribute to determine whether and which management data is inserted in the SA-bits. Ifmanagement data is inserted in the SA-bits, then it is inserted in SA registers SA5, SA7 and SA8. SA4 isused as a control register and contains bandwidth information.The saBits attribute has the following possible values:ValueTransparento10ManagementpathManagementDescriptionNo management data is inserted in the SA-bits. The SA-bits are passedtransparently.This inserts the proprietary Telindus O10 protocol in the SA-bits. This allows youto forward management data over the E1 interface in a similar way as you canover the control port. This allows more flexibility in managing your network ofTelindus devices.This inserts path management information in the SA-bits. This allows you tomanage complete paths instead of managing individual devices (i.e. elements).For more information on path management, refer to the Path Managementmanual.o10-PathManagementThis inserts both the proprietary Telindus O10 protocol as the path managementinformation in the SA-bits.• Note that forwarding management data over the E1 interface can be very slow. The speed liesbetween 200 and 1200 bps.• When running an external loop-back test on an E1 interface, AIS bits are only sent to the application ifthe value of the saBits attribute is set to transparent. In all other cases, timeslot 0 is unchanged in ordernot to lose O10 and/or path management information.• It is important to enable CRC-4 insertion when the saBits attribute is set to include O10 and/or pathmanagement information. Refer to Section 5.5 - Configuring the E1 interfaces.User manual 55

Crocus DXCStep-by-step configurationExample – management over the E1 interfaces (continued)In the network depicted on the previous page, the E1 interfaces of the Crocus DXC are connected to theE1 interfaces of several modems. By setting the appropriate attributes, the management data can passfrom the Crocus DXC to the modems.Special points of interest in this network are:• On E1 interface 1 and TT 1, you have to set the saBits to o10Management or o10-pathManagement. By doingso, you are able to forward management data over the E1 interface connection between the CrocusDXC and TT 1.• On E1 interface 2 and 3 and on both modem A and B of CV 1, you have to set the saBits too10Management or o10-pathManagement. By doing so, you are able to forward management data over theE1 interface connection between …− E1 interface 2 and CV 1 modem A.− E1 interface 3 and CV 1 modem B.• On CV 2 the situation is different than on CV 1, because on CV 2 internalDmm is enabled. This meansthat management data is exchanged between modem A and B. This implies that …− you can reach modem B through modem A and vice versa.− you can not set the saBits to o10Management or o10-pathManagement on the E1 interface connectionbetween E1 interface 5 and modem B. Else you create two possible paths towards themanagement system. E.g. modem A could be reached over its E1 interface connection as well asthrough modem B. In this case, you might get unexpected results. Therefore, make sure there isonly one path towards the management system!User manual 57

Performance attributesCrocus DXC8.2 Introducing the performance attributesPerformance information can be used for the following:• If network problems arise, information about the history of the communication link can be reviewedand analysed. 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.The following table explains the performance information timing.Performance timing2 hours,24 hours,7 daysDescriptionThe performance information is accumulated during a certain time span,called a period. After a period, the accumulated performance information iswritten into a buffer. Then a new period starts. An interval contains severalperiods:• 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. everyperiod (15 minutes, 2 hours or 24 hours) the most recent measured andcalculated values are added, and the oldest values are lost.since bootIn this case, the performance information is kept since the latest cold boot ofthe Crocus DXC. This can be considered as a performance informationsummary.The Crocus DXC does not contain a real-time clock, therefore time information is related to its internalclock. To allow you to situate the time intervals in the real time, the sysUpTime attribute is returned togetherwith the performance information. It reflects the time since the latest cold boot of the Crocus DXC.Only the available performance information is displayed. If the interrogation happens shortly after boot, novalues 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.88 Reference manual

Alarm attributesCrocus DXC9.2 Introduction to the alarm attributesBefore discussing the alarm attributes of the Crocus DXC in detail, some general information on thealarm attributes of the Crocus DXC is given.The following table gives an overview of this section.Section Title Page9.2.1 Configuration alarm attributes 1019.2.2 General alarm attributes 1039.2.3 Alarm signalling 104100 Reference manual

Crocus DXCAlarm attributes9.2.1 Configuration alarm attributesThe following four configuration alarm attributes are already explained in Chapter 6 - Configurationattributes, but are explained more thoroughly below.crocusDXC/…/alarmMaskUse this attribute to mask or unmask the alarms of an object. This determines whether an active alarm isforwarded to the central management system (e.g. HP OpenView) or not.The alarms in the alarmMask attribute have the following values:enableddisabledValueIs the active alarm being forwarded to the central management system?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 (e.g. HP OpenView).Only the most important alarms are unmasked (i.e. enabled) by default. All other alarms are masked (i.e.disabled).crocusDXC/…/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 alarm attribute of the top objectcrocusDXC.Continued on next pageReference manual 101

Alarm attributesCrocus DXCConfiguration alarm attributes (continued)crocusDXC/…/alarmContactHighMaskUse this attribute to mask or unmask the alarms of an object. This determines whether an active alarmactivates the high alarm contact of the CN4 card nest or not. By connecting an alarm circuit to the alarmcontact, e.g. a light bulb or a buzzer, you can generate an external alarm.The alarms in the alarmContactHighMask attribute have the following values:enableddisabledValueDoes the active alarm activate the high alarm contact of the CN4 card nest?Yes. So the alarm is unmasked.No. So the alarm is masked.For more information on the high alarm contacts, refer to the CN4 card nest manual.All alarms are masked (i.e. disabled) by default.crocusDXC/…/alarmContactLowMaskUse this attribute to mask or unmask the alarms of an object. This determines whether an active alarmactivates the low alarm contact of the CN4 card nest or not. By connecting an alarm circuit to the alarmcontact, e.g. a light bulb or a buzzer, you can generate an external alarm.The alarms in the alarmContactLowMask attribute have the following values:enableddisabledValueDoes the active alarm activate the low alarm contact of the CN4 card nest?Yes. So the alarm is unmasked.No. So the alarm is masked.For more information on the high alarm contacts, refer to the CN4 card nest manual.All alarms are masked (i.e. disabled) by default.102 Reference manual

Crocus DXCAlarm attributes9.2.2 General alarm attributesThe general alarm attributes totalAlarmLevel and alarmInfo are explained below.crocusDXC/totalAlarmLevelThis attribute is only present in the top object of the containment tree of the Crocus DXC, crocusDXC.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. HPOpenView) where it determines the colour of the icon. This colour is an indication of the severity of thealarm.crocusDXC/…/alarmInfoThe alarmInfo contains the actual alarm information of the corresponding object. The alarmInfo attributesare:AttributediscriminatorcurrentAlarmspreviousAlarmsDisplays for the corresponding object …the total alarm count since the last cold boot.the current alarms.the second most recent alarms.alarmMask the alarmMask as configured in the Configuration group. Refer to Chapter 6 -Configuration attributes.alarmLevel the alarmLevel as configured in the Configuration group. Refer to Chapter 6 -Configuration attributes.Reference manual 103

Alarm attributesCrocus DXC9.2.3 Alarm signallingIf you do not have a central management system, you could perform alarm signalling with the alarmcontacts of the CN4 card nest.ExampleSuppose that you …• set the LOS alarm of the e1Interface[ ] objects to enabled in the alarmContactHighMask.• connect the high alarm contacts of the CN4 card nest to an external alarm circuit (e.g. with a lightbulb).Now, when on one of the E1 interfaces an LOS alarm occurs, the light bulb will light up.104 Reference manual

You can also use TML without opening TMA.To download firmware with TML, proceed as follows:StepAction1 Connect a serial port of your computer(e.g. COM1) through a straight DB9male - female cable with the controlconnector of your Crocus DXC asshown in the following figure:2 Open a DOS window on your computer.3 Go to the directory where the TML executable is located. Typically this isC:\Program Files\TMA.4 Place the firmware file you want to download in this directory.5 Type the following command: tml -c1 –v -f@CONTROLwhere …• tml is the executable (Telindus Memory Loader) to download files to the Telindusdevices through their control port• -c1 specifies the COM port of the computer connected to the Crocus DXC (in thisexample COM1)• -v returns graphical information on the download status• -f is the firmware file you want to download (e.g. T1212001.00)• CONTROL (in capitals!) specifies that the destination is a flash bank of the CrocusDXC.To see a list of all the possible TML options: type TML in your DOS windows and pressthe ENTER key.6 If you press the ENTER key, the firmware download begins.If you used the –v option together with the TML command, a graphical bar shows thedownload progress.Reference manual 115

Firmware downloadCrocus DXC11.3 Downloading in boot modeWhen a flash memory software download has failed or when a flash memory error occurs, it may bepossible that the Crocus DXC becomes inaccessible. In that case, new software can still be downloadedby setting the Crocus DXC in boot mode. This is done by means of the start-up mode DIP switch.The location of the start-up mode DIP switch is:DIP switch name DS1 no. Setting Functionstart-up mode1 on Start up from flash memory.offStart up in boot mode.The Crocus DXC can be forced in boot mode by setting DIP switch bank DS1 position 1 to off. If a newsoftware download is successfully completed, the DIP switch must be reset to on in order to restartoperation from flash memory.Note that this DIP switch setting cannot be overruled by TMA.To download firmware to a Crocus DXC in boot mode, proceed as follows:StepAction1 Disconnect the Crocus DXC from the power supply.2 Set DIP switch bank DS1 position 1 to off.To locate this DIP switch bank and for the DIP switch setting procedure, refer to Chapter3 - DIP switches and straps of the Crocus DXC.3 Reconnect the power supply to the Crocus DXC.⇒ The Crocus DXC is now in boot mode.4 Now proceed as explained in the previous section, Section 11.2 - Downloading withTML.5 When the download is finished, disconnect the Crocus DXC from the power supplyagain.6 Reset DIP switch bank DS1 position 1 to on.7 Reconnect the power supply to the Crocus DXC.116 Reference manual

Crocus DXCFirmware download11.4 Downloading via a management concentratorIf many Crocus DXC Card Version modems need a firmware update, it is more efficient to use thesoftware distribution feature of a management concentrator (e.g. the Orchid 1003 LAN or Telindus 1035Orchid). In that case, the firmware file that is present on the file system of the management concentratoris downloaded over the high speed bus to the Crocus DXC CV.Also the Crocus DXC CVs their remote counterparts (which are often Table Tops) can get a firmwareupdate using the management concentrator its software distribution feature.For more information, refer to the manual of the management concentrator.Reference manual 117
