Abstract

Improved DSL and/or other communication system services can be provided by motivating users, service providers and operators to implement and comply with one or more operational conditions, such as parameter value limits and/or ranges, that enhance operation of the communication system. Enhanced operation can include providing a reward such as an operational benefit to one or more users and/or mitigating problems experienced by other users in the communication system, which can be one or more communication lines. A DSL line implementing and complying with one or more operational conditions is provided with a reward (such as an operational benefit like a higher maximum data rate), which is otherwise withheld if the line fails to comply with the condition(s). Each operational condition may be set and monitored by a controller, such as a DSL optimizer that collects and analyzes operational data to determine compliance. Other requirements may be imposed for a DSL line to be eligible for the reward, such as the requiring the DSL line to provide operational data to the controller and requiring the DSL line's acceptance of control signals from the controller. The controller can use the operational data and line control to enhance system operation, for example to reduce crosstalk between lines in a common binder.

More particularly, the operation interests among some embodiment can relate to the obtainable maximum data rate of communication line.For example, given maximum rate R _NCCan divide that circuit meets and the boundary between non-meeting.In such embodiment, when the circuit operational-condition compliance, this circuit may operate in R _NCOn, and the circuit that does not meet service conditions can not adopt and is higher than R _NCData rate.Service conditions can be one or more a plurality of operational parameter values, and for example the DSL circuit transmits the Maximum tolerance of data in the DSL system.When circuit operation exceeded the operational condition value for Maximum tolerance rank (for example, according to the MAXSNRM parameter measurement in ADSL1 and the ADSL2 system) setting, this circuit was restricted to and is not higher than R _NCData rate.The user who operates in or be lower than for the operational condition value of Maximum tolerance rank setting is allowed to be higher than R _NCData rate transmit.As that kind that it will be appreciated by those skilled in the art that,, can also use other operation interests and other service conditionss except that relating to the Maximum tolerance restriction except that maximum data rate according to the present invention.

In certain embodiments of the invention, controller (for example DSL optimizer and/or Dynamic Spectrum Management device) is provided with service conditions for the DSL circuit.This controller is gathered service data, and these service datas allow this controller monitoring wire meeting service conditions.When circuit is ineligible; The controller prevention perhaps stops the operation of this circuit or performance is awarded or the execution of interests; And/or prevent or stop and identically (for example face the territory operating in; Same electric wire is tied or possibly is same telephone operator zone or central office) in any or whole circuits operation or performance is awarded or the execution of interests, the maximum data rate through any main line of restriction for example.When circuit is in match state, award is provided to this circuit (and possibly be the All other routes of safeguarding by this ISP, suppose that these All other routes are in match state equally).Controller is gathered service data, analyzes this data, produces operating instruction to the DSL circuit then and realizes embodiments of the invention.Under the situation that adopts a plurality of service conditionss; Can require circuit to meet the smallest subset of all conditions or these conditions; So that (can comprise in addition, the benefit to the All other routes that also in approximate accordance, moved by this ISP) rewarded in the useful operation of the qualified acquisition of these circuits.After checking the present invention, this or other variations of the present invention are obvious to those skilled in the art.

With common use or the independent fully mode of using, the multiple network management essentials are used to carry out the management of ADSL and VDSL physical layer resources, and key element refers to the parameter or the function of the modem pair of ADSL or VDSL here.Network management framework comprises one or more by management node, and each node comprises an agency.By management node can be router, bridge, switch, modulator-demodulator or other equipment.At least one is commonly called gerentocratic network management system (nms) to being kept watch on and control by management node, and usually based on common PC or other computers.Manager and agency use NMP to come exchange of management information and data.The unit of management information is an object.The related object collection is defined as management information bank (MEB).

Fig. 1 illustrates the G.997.1 model reference system of standard (G.ploam) of basis, and as well known to those skilled in the art, this system applies is in various ADSL and VDSL system, and the embodiment of the invention can be implemented in these systems.This model is applied to meet the ADSL that comprises or do not comprise splitter and the VDSL system of variety of protocol; For example ADSL1 (G.992.1), DSL-Lite (G.992.2), ADSL2 (G.992.3), ADSL2-Lite are G.992.4, G.993.X ADSL2+ (G.992.5), VDSL1 (G.993.1) and other form the VDSL standard; Also have G.991.1 and DHDSL standard G.991.2, all above-mentioned systems have or do not have binding (bonding).These standards, its variation and they and G.997.1 relevant application are known to those skilled in the art.

G.997.1 standard is for having stipulated physical layer management based on the clearly ADSL and the VDSL transmission system of embedded operation channel (EOC), and this EOC defines in G.997.1, and uses the G.992.X indicator bit and the EOC message of standard definition.Further, G.997.1 stipulated the content of network management element for configuration, fault and performance management.When carrying out these functions, the multiple service data that system's utilization can be obtained and gather on access node (AN).The TR69 report of DSL forum has also been listed MIB and how have been visited MIB.In Fig. 1, customer terminal equipment 110 is connected on the home network 112, and this home network 112 is connected to network temination unit (NT) 120.Situation for the ADSL system; NT120 comprises that ATU-R122 (for example; Modulator-demodulator by the definition of one of ADSL and/or VDSL standard also can refer to transceiver in some cases) or any other network terminal modulator-demodulator that is fit to, transceiver or other communication units.Remote equipment in the VDSL system can be VTU-R.As that kind understood by one of ordinary skill in the art and described herein, each modulator-demodulator is mutual with connected communication system, and can generate the service data by the decision of the modem performance in the communication system.

NT120 also comprises management entity (ME) 124.ME 124 can be any suitable hardware device, the circuit state machine in microprocessor, microcontroller or firmware or the hardware for example, and these equipment can move according to the requirement of applicable standard and/or other standards.ME124 gathers and stores the performance data among its MIB; This MIB is the information database of being safeguarded by each ME, can conduct interviews through the NMP such as Simple Network Management Protocol (SNMP); This snmp protocol is a kind of management (Administration) agreement; Being used for from the network equipment acquisition of information offers supervisor console/hypervisor or provides through the TL1 order; This TL1 is the command lanuage of having established for a long time, is used for arranging response and the order between the telecommunication network element.

Each ATU-R in the system is connected to and is positioned at central office (CO) or other ATU-C up and/or center.In the VDSL system, the VTU-R in each system is connected to and is positioned at CO or other VTU-O (for example, any line scan pickup coil side equipment such as ONU/LT, DSLAM, RT etc.) up and/or the center.In Fig. 1, ATU-C142 is positioned at the access node (AN) of CO 146 and locates.As it will be appreciated by those skilled in the art that, AN140 can be the DSL system unit, for example DSLAM, ONU/LT, RT etc.ME144 is same to safeguard the performance data MIB relevant with ATU-C 142.As that kind that it will be appreciated by those skilled in the art that, AN140 can be connected to broadband network 170 or other networks.ATU-R 122 and ATU-C 142 are joined together through loop 130, and this loop is the twisted pair telephone that also carries other communication services in ADSL (and VDSL) usually.

Part in the interface shown in Figure 1 can be used to confirm and gather operation and/or performance data.In the different scope of interface shown in Figure 1 and other ADSL and/or VDSL system interface scheme, these systems are well-known, and these differences are known and obvious to those skilled in the art.Q interface 155 provides interface between the ME 144 of the NMS 150 of operator and AN 140.All parameters of in standard G.997.1, stipulating all are applied to Q interface 155.The near-end parameter that ME 144 is supported is obtained from ATU-C142, and obtains from can two interfaces from u interface any one of the far-end parameter of ATU-R 122.Channel 132 sends and in indicator bit and EOC message that pmd layer provides, can be used in ME 144, generate needed ATU-R 122 parameters through embedding.Alternatively, operation, operation and management (OAM) channel and suitable agreement can be used for when ME 144 requires, from ATU-R 122, fetching parameter.Similarly, the far-end parameter from ATU-C 142 can be obtained from any in two interfaces on the u interface.Indicator bit that on pmd layer, provides and EOC message can be used in the ME122 of NT 120, generate needed ATU-C 142 parameters.Alternatively, the OAM channel can be used for when ME 124 requires, from ATU-C 142, fetching parameter with the agreement that is suitable for.

In u interface (being loop 130 in essence), there are two management interfaces, one at the ATU-C142 place (U-C interface 157), and one at ATU-R 122 places (U-R interface 158).Interface 157 provides ATU-C near-end parameter for ATU-R 122, so that obtain through u interface 130.Similarly, interface 158 provides ATU-R near-end parameter for ATU-C 142, so that obtain through u interface 130.The parameter that is adopted can depend on the transceiver standard that adopted (for example, G.992.1 or G.992.2).

G.997.1 standard code the optional OAM communication channel through u interface.If realize this channel, ATU-C and ATU-R transmit physical layer OAM message to using this channel.Thereby the transceiver 122,142 of this system is shared in the various operations and the performance data of preserving among its MIB separately.

Can be in March, 1998 on the date, from the title of ADSL forum among the DSL forum technical TR-005 of " management of ADSL network element ", find more information about ADSL NMS.Also have, the date is in January, 2004, from the title of the DSL forum work text WT-87 (Rev.6) of DSL forum for " CPE WAN management agreement ".Also have at last, the date is on January 5th, 2005, from the title of the DSL forum work text WT-082v7 of DSL forum for " local area network side DSL CPE configuration instruction book ".These files have proposed the different situations of cpe side management, and information wherein is well known to a person skilled in the art.More information about VDSL can find in the DSL forum that G.993.2 the ITU standard (is called as " VDSL2 ") sometimes and some are the making progress work text during G.993.1 the ITU standard (is called as " VDSL1 " sometimes) and forms, and these all are known in those skilled in the art.For example, can in following file, obtain other information: the DSL forum technical TR-057 (former WT-068v5) that is entitled as " management of VDSL network element " (in February, 2003); The technical report TR-065 that is entitled as " FS-VDSL EMS requires to the NMS interface function " (in March, 2004); And in forming to the ITU standard of VDSL1 and VDSL2 MIB key element version G.997.1; Perhaps draft Dynamic Spectrum Management in ATIS North America is reported NIPP-NAI-2005-031.

In ADSL, share same bundle circuit and can adjust in same Line cards or same on the equipment of transmission and stop, be unlikely like this, but bundle to terminate in but be practicable among the VDSL in this same line an outpost of the tax office (same-line-card).Yet, can extend to ADSL to the discussion of xDSL system, this is owing to can take the common termination (particularly in the DSLAM of the renewal that can handle ADSL and VDSL) of same-binder lines.In the canonical topology of dsl device, the transceiver of some is to being in service and/or can utilizing, and the part of each local loop disposes with many loops to other users in bundle (perhaps bundle (bundle)).After very being close to the frame of client's front device (CPE), loop adopts the form of lead-in, and exists with the form of bundle.Therefore, local loop passes two different environment.The part of loop can be arranged in ties, and loop is sometimes shielded from outside electromagnetic interference and comes here, but but can be crosstalked.After frame, when for most of lead-ins, when this to bundle away from other to bundle the time, lead-in does not receive cross talk effects usually; But because lead-in does not have conductively-closed, therefore transmission still can be weakened by electromagnetic interference significantly.All have 2 to 8 twisted-pair feeders in many lead-ins, and perhaps connect under the situation of (the multiplexing or demultiplexing of a service) in the ownership of a plurality of these circuits of services arrival, significantly crosstalking in addition possibly take place between these circuits of introducing line segment.

Fig. 2 shows common exemplary DSL deployment scenario.All local loops of (L+M) individual user 291,292 pass at least one common binder altogether.Each is with being connected to central office (CO) 210,220 through industrial siding per family.Yet each local loop also can pass different environment and medium.In Fig. 2, L client or user 291 are connected to CO 210 through the combination of using optical cable 213 and copper twisted pairs 217, this typically refer to optical cable to the chamber (Fiber to the Cabinet, FTTCab) or Fiber To The Curb (Fiber to the Curb).From the signal of transceiver 211 among the CO 210, by ONT Optical Network Terminal 215 among optical line terminal 212, the CO 210 and optical network unit (ONU) 218 conversions.Modulator-demodulator 216 among the ONU 218 serves as the transceiver of signal between ONU 218 and the user 291.

The common subscribers feeder that stops in position such as CO 210,218 and ONU 220 (and other) can be operated with the such coordination of for example vector quantization (coordinated) mode.(for example vector quantization ADSL and/or VDSL system) can reach the coordination of signal and processing in the communication system of vector quantization.When many line transmissions from DSLAM or LT were produced by common clock and processor jointly, descending vector quantization will take place.In having the VDSL system of this common clock, crosstalking between the user takes place with respect to each audio frequency independently.Like this, for many users, each downstream tones can independently be produced by public vector transmitter.Similarly, when common clock and processor are used for receiving the signal of many circuits jointly, up vector quantization will take place.In having the VDSL system of this common clock, crosstalking between the user produces with respect to each audio frequency independently.Like this, for many users, each upstream tones all can be come independent process by public vectorial receiver.

M remaining user 292 loop 227 is copper twisted pairs just, refers to optical fiber to office (Fiberto the Exchange, situation FTTEx).Any maybe and economically feasible the time, FTTCab is superior to FTTEx, because FTTCab has reduced the copper part of local loop, thereby has increased accessible speed.The existence of FTTCab loop can throw into question to the FTTEx loop.In addition, hope that FTTCab will become general gradually topology in future.Such topology can cause significant crosstalk interference, and might mean, because the specific environment of its operation, the circuit of different user has different Data-carryings and performance capability.This topology can be that fiber-fed " chamber " circuit and exchange line are mixed in same bundle.

As can be seen from Figure 2,292 Line sharing ties 222 from CO 220 to the user, and does not use this bundle 222 from the circuit between CO210 and the user 291.Further, another bundle 240 for all lead to/from CO 210 and CO 220 with and separately user 291,292 circuit be public.In Fig. 2, far-end cross talk (FEXT) 282 and near-end cross (NEXT) 281 are illustrated as at least two that influence in the circuit 227 that is configured in CO220.

As that kind that it will be appreciated by those skilled in the art that, at least a portion in described service data of these files and/or the parameter can be used with embodiments of the invention.Further, at least a portion of system description can be used in an embodiment of the present invention equally.Can find the different types of service data and/or the information that can from ADSL NMS, obtain therein, other are known to those skilled in the art.

The flow chart of Fig. 4 shows one embodiment of the present of invention.Method 400 is with 410 beginnings, with the maximum allowable number of in the communication system or more circuits according to speed R _MaxBe set to the non-rank R that meets _NCAt 415 places, give any system line of participation condition/reward incentives program then with the value and/or the limitation notification of the accordance that is used to definite any applicable service conditions.Should " communication system " can be any kind system (for example; The DSL system), and can comprise single line, many circuits, bundle, all circuits in cable, whole service merchant's sets of lines, single ISP's all circuits, CO or the zone or the like.In 420, use R _MaxFunctional arrangement is according to normal operation transmission data.In 430, can the employed any service conditions of measurement circuitry, for example use the service data of being gathered.In judgement 440, assess accordance then.If circuit does not satisfy accordance, then in 450, keep R _MaxPerhaps with R _MaxBe re-set as R _NCIf circuit satisfies accordance, in 460, keep R _MaxPerhaps with R _MaxBe re-set as R _COMPLYAlternately, when detecting accordance, can be only with R _MaxFrom R _NCDischarge in the restriction.In case in 450 or 460, carry out the speed adjustment, circuit returns the operation at 420 places, and can be reappraised afterwards.Method 400 and any other method of the present invention can realize on computer program that this is stated computer program and comprises machine-readable medium and be included in the program command on this machine-readable medium.These program instructions specify disclosed herein one or more a plurality of methods.

Whether circuit is had the right to obtain to move the assessment of interests and/or to any other assessment of service data, can be needed as based on the nearest obtainable service data relevant with service conditions, perhaps based on historical data and current data.If the use historical data, can be in any suitable manner weight in addition.For example, can give every circuit and/or service conditions with data weighting vector (W), the current like this function that can be used as the current degree of data with weight historical data is used.For example,, then when estimating accordance, identical weight is gone over three update cycles the data in (for example, sky) if weight vectors is W1=[111].If weight vectors is W2=[10000000.5], come from last data of being reported the service conditions data so and have weight 1, the data that come from 7 update cycles (for example, before the week) early have weight 0.5.Ignore the data that come from other update cycles.If hope to use only from bimestrial data of past according to identical weight, adopt one day so during as the update cycle, weight vectors has 60 length, and all is 1 (W3=[111...111] just).According to embodiments of the invention, can use different weight vectors to different service conditionss, for example, depend on whether read as the basis of confirming circuit or system operation interests and/or other changes with single.

Except the time of considering service data, whether circuit, system etc. is had the right to obtain the assessment of any operation interests and/or to other assessments of service data, can be needed as based on enough obtainable service datas.For example, in some cases, data acquisition system possibly break down or by deexcitation, have only in other words very little or do not have an available service data.In these cases, when not having enough data when making reliable assessment basic, system abandons system and/or circuit operation are made any change, perhaps abandons making any restriction and/or available parameter, possibly be helpful like this.In order to prevent to carry out inappropriate change, the execution of change can be limited in only to the situation of perhaps in one section official hour, having gathered abundant excessive data from last assessment.Can use radix technology and data probability distributions to check service data.Can use ripe distribution estimating technology to reduce the influence of past data far away and the data that enhancing is gathered recently, these technology are known to those skilled in the art.If do not satisfy data abundance property and time rule, circuit can only keep current state so, makes till the new data that such rule is satisfied up to having gathered.

As shown in Figure 5, an alternative embodiment of the invention adopts slightly different operation to reward and to its adjustment.In method 500, its transmitting uplink data frequency band of adsl line is set to f _Low≤f _Transmit≤f _HighUpper limiting frequency f _HighBe used for uplink, and can select, perhaps reach other preferred targets with minimise cross talk in appropriate initial rank.In 520, suitably use this frequency band to operate this circuit then.In 530, measure the accordance of (for example, crosstalking does not surpass specified threshold value), and this accordance preferably can be based on the service data of being gathered with given compatibility standard.In 540, judge accordance with one or more a plurality of service conditionss.If circuit does not meet the service conditions that is adopted, then adopt current frequency bandwidth to continue this circuit of operation in 520.If the circuit operational-condition compliance is then judging that rank (it is different disturbing with any service conditions that adopts) is disturbed in assessment here in 550.If the interference compatibility of circuit operation is exactly a service conditions, judge that so 540 and 550 can merge into a step.If circuit operational-condition compliance and do not exceed the interference rank will increase the upper limit f of frequency band so in 560 _HighCan in fact, perhaps, increase f through improving the frequency rank through increasing the highest frequency upper limit of frequency band _HighIn 520, next circuit adopts newly-installed frequency band to move.If the upper end of frequency range is too high, can in 570, reduce f so _High

In other embodiments of the invention, can be so that qualified circuit obtain less restrictive PSDMASK, and ineligible circuit is imposed more restrictive PSDMASK.In addition, CARMASK and/or BCAP [n] can use equally in a comparable manner.And in certain embodiments, the power spectral density rank of a plurality of frequency bands and any one frequency band can be used for confirming accordance.Other operational factors and/or characteristic are obvious to those skilled in the art.Further, can also use other awards of a plurality of level of a plurality of level of conformance of foundation among the present invention.

More particularly, embodiments of the invention comprise method, device and computer program, the example below can in these methods, device and computer program, implementing:

Example 1---only when the DSL service that is directed against all identical suppliers in the same cable, when the Maximum tolerance of measuring at all audio frequency places was no more than 11dB, qualified system was to transmit up to the downstream data rate that meets maximum data rate.The appropriate regional power spectral density masks of qualified modulator-demodulator observation can be required, and all audio frequency in this mask should be the measurement of Maximum tolerance put on.When the ISP can't confirm that all DSL of himself have used Maximum tolerance in the public domain; Maximum data rate should not surpass the non-maximum data rate that meets of the service that is provided in this zone, and still must adhere to adopting power spectral density masks.Further, the transmission descending power of any ADSL service can be limited in not being higher than 20.5dBm.In the situation of all ADSL2, the PSDMASK of programmed representes should be by the maximum power spectral densities of finding simultaneously.If at the appointed time at interval (for example; 15 minutes) the code violation counting measured surpasses 250 (perhaps selected appropriate threshold) in protection place of obtainable maximum impulse, then can require ISP DSM accordance in set place of any Maximum tolerance.

If example 2---identical supplier all DSL route surveys in same-bar cable to given restriction (for example; 11dB is perhaps still less) interior Maximum tolerance; Then qualified system is transmitted with the data rate up to maximum data rate on loop; Minimal attenuation value (for example, 40dB or approximate 13000 feet loops) is satisfied in measured up decay, and can use the power up to 20.5dBm.Qualified modulator-demodulator can be at 138kHz to any PSD value of using the carrier mask that is lower than ISP's regulation between the 500kHz; Suppose that this mask is no more than-28dBm/Hz at any frequency place that is lower than 138kHz, and be no more than-32dBm/Hz at any frequency place that is higher than 138kHz.In any use of such long range compliance, should satisfy all POTS-protection requirements.

If example 3---in a bundle on all audio frequency of all identical supplier's circuits; Measured up MAXSNRM is no more than 11dB; (for example then be shorter in length than given maximum line length; 9000 feet or the up decay of measuring are lower than 30dB) qualified ascending communication system can be used the audio frequency that is up to audio frequency 63 on the circuit, transmit with the data rate of height to 2.5Mbps.Under all such situation, it is other that PSD can be no more than given even lower level.Do not find that MAXSNRM is that the qualified up-link of 11dB is transmitted with the data rate that is not higher than 384kbps.

Example 4---if the MAXSNRM on all audio frequency (just frequency band is preferred) is equal to or less than 11dB, and MAXATP＜10dBm, and then qualified VDSL system correctly carries out the PSDMASK of limited ISP's programming.To being restricted to of PSDMASK, must abide by (for example, between 1.1 to 4.4MHz) applicable PSD constraint in given frequency range.

In the system that uses such as the top method that proposes, technology and device; Observe the DSL circuit of margin limits with good conditionsi, characteristic and/or parameter, will help to alleviate the negative effect that causes by crosstalking in the DSL system, too high power etc. other users' signal.The availability excitation user that higher data rate and/or other operations are rewarded adopts rational margin limits etc.It will be understood by those skilled in the art that according to the present invention, can in various communication systems, adopt other service conditions and award.

Employing is such as technology disclosed herein, method and apparatus, and can reach is not only the DSM achievement of a cover maintenance parameters.DSM can also comprise the spectrum-management standards ability, to distinguish and to adjudicate the DSL spectrum compatible property in the cable.If set about carrying out compatibility specification task, for example adopt embodiments of the invention, then general high speed DSL disposes the possibility more that becomes, and can be used for confirming and encourage DSL deployment faster.

The ADSL downstream transmission signals typically has-power spectral density (PSD) restriction of 40dBm/Hz.Actual PSD can be up to more than the 2.5dB, but it on average must be on this level.In addition; Though-40 roughly are meant most of frequency bands; But can be in the annex of various criterion and in T1.417 spectrum-management standards (other countries possibly have the document that is similar to the T1.417 spectrum-management standards) for example to the North America, find accurate PSD template to zones of different.The ADSL down-link transmitter can use the through-put power up to 20.5dBm.Unfortunately, only under the situation that whole downstream bands is activated, 20.5dBm could with should-the 40dBm/Hz restriction is allowed simultaneously, and the situation that whole downstream bands activates only accidental generation in short loop.Typically, short loop does not require the through-put power of 20.5dBm, and this is to be higher than the desired speed on these short loops usually far away because maximum can reach data rate.On the other hand, usually must use the long loop of whole 20.5dBm through-put powers, but the restriction owing to-40dBm/Hz PSD is limited to the numerical value that is low to moderate 12-13dBm.Yet as that kind that it will be appreciated by those skilled in the art that, long loop requires higher power, and has seriously limited the DSL generality in the loop qualification for inappropriate transmit power restrictions of these longer DSL loops.The embodiment of the invention can help to provide more effectively and the adapt that still less bothers; Come to realize better communication system for sharing the various users that tie, this adapt is the adapt to the variation of these types of the demand of loop-length and power and restriction.

Extra 6dB through-put power (when still being lower than 20.5dBm) is about 1000 feet additional range on any long loop almost.Be low to moderate on the speed of 100kbps, 1000 feet additional range can change the DSL economy significantly.Like this; Spectrum management in advance allows and encourages on the short loop more broadband, more high-power ADSL downlink transfer; Thereby set up to get into the maximum of crosstalk in the longer loop that has been weakened, this longer loop produces crosstalking and must transmit with lower power still less.If short loop is positioned at the older longer ADSL signal based on CO and shares on the remote fiber feedback terminal of tying (remote-fiber-fed terminal), then the ADSL situation can worsen more.Adsl deployment surpasses 90% in the North America is disposed, increased the scope of being put into practice caused problem by these.

The embodiment of the invention provides spectrum management system, method, device and the technology based on excitation, with more reasonably using of encouragement telecommunication system resources, and hinders those practices that the family causes disadvantaged user's service disruption and/or degeneration.In certain embodiments, controller can encourage MAXSNRM parameter correct Application more widely, and this parameter is left in the basket at present or is observed by error with very high ratio in DSL basis, North America.Other are these technological themes about tolerance limit and/or the parameter that influences performance too.Can reach desired excitation through allowing circuit to enjoy interests, to enjoy the interests that can't obtain for those circuits of not observing this restriction, the consistent and/or general use of this circuit is just at 11dB or other Maximum tolerance of even lower level.For example, the circuit of in ADSL1, allow observing the Maximum tolerance restriction transmits with height to the speed of 7Mbps, and the circuit that will show excessive 17dB or more tolerance limits is limited in lower 1.5Mbps speed.Like this, excitation ISP and seller alleviate and/or reduce overall crosstalk through correct with use " based on the courtesy of parameter " widely.As that kind that it will be appreciated by those skilled in the art that, it is possible that the probability that under such practice, reduces service disruption is assessed.In another one embodiment of the present invention; When loop-length during greater than the 12k foot (for example; When assessing through the up decay of report), if for the speed of height to 768kbps, tolerance limit＜MAXSNRM=11dB; Then controller can allow the 20.5dBm transmission on the adsl loop road, and has no the PSD constraint.

Embodiments of the invention can also be compatible with the symmetric services such as HDSL (the perhaps following SHDSL), and this symmetric services and ADSL share and tie.Causing a consideration of-40 dBm/Hz PSD masks of ADSL is that the descending ADSL near-end cross (NEXT) that gets into up HDSL receiver can jeopardize HDSL (or SHDSL).

Whether probability can clearly be expressed maximum length HDSL and tie with the ADSL that grows very much that needs 20.5dBm power (and the PSD that is higher than-40 dBm/Hz) is shared.If HDSL only be present in the DSL circuit 2% on, and the long ADSL conditional probability adjacent with HDSL only is 10% (is not very possible because of long transmission line) in bundle (perhaps cable), this probability is 0.02% so.Further, crosstalking between these two circuits can cause the incompatibility of HDSL service disruption under 1% worst case rank.In addition, there are some so long ADSL all just can cause problem (remind: correct MAXSNRM observes the power that will reduce most of adsl circuit) with maximum power transfer.Like this; The probability of being assessed is reduced to far below 0.000002; Perhaps each is in 1,000,000 twice (if no matter the probability during-40 dBm/Hz transmission that on all frequencies, allows with maximum well below all ADSL as that kind that in current T1.417, is allowed to, is why).

Like this, under the rule of flexibility formerly, very low, but be to have bigger incompatible probability.No matter be that long loop ADSL user's that possible millions of speed is lowered to practice thrift the loss probability on the small amount of H DSL only; Still substitute small amount of H DSL with fiber optic circuit, the probability of reduction/replacement demand will be higher than in said fixing/static spectrum management according to the probability in the management that the present invention is based on excitation.In some examples of discussing herein, loop information operation report and/or that assess out, for example loop-length and decay as the input of the judgement of using 20.5dBm, can bring the marked improvement of DSL service.As that kind that it will be appreciated by those skilled in the art that, use extra information can further reduce the probability of service disruption.

Further, point out by error that sometimes the ISP does not understand other loops in tying.In fact, the ISP can carry out " loop is formed report " on any circuit, and finds the situation with other services in a bundle or the cable.If these records come forth and be obtainable for any competitive service supplier; And through using these records from any DSL service of current service supplier, to select pairing, then these records can not use under the situation of not adjusting the non-fact.Can also these records and noise/crosstalk in measured or the ADSL system reported be connected then.Then just know the position of the HDSL that possibly be affected on a small quantity at an easy rate, also be easy to replace their (perhaps being more preferably the DSL that still can work) with optical fiber.

Higher upstream data rate is normally attracting, particularly for some application.The ADSL2 standard has annex J and M, allows wideer upstream bandwidth, and allows the overlapping of uplink and downlink at least in theory.The NEXT that comes from the descending ADSL receiver of entering of the increase that causes thus for the worry of the wideer upstream bandwidth of ADSL2 modulator-demodulator.G.992.2/5 the noise of the relative loop-length of certain hypothesis takes place in the supposition of annex cut-off frequency of advising and bandwidth, and this is can not be applied under most of concrete conditions.One or more a plurality of embodiment discussing above using can use in following getable extra bandwidth of these standards in some cases.

In the another one example; The service data of being gathered can show; Observe the uplink of given circuit of the MAXSNRM of 11dB, and can not have the PSD constraint and under total uplink transmit power of 13.5dBm, use wideer upstream transmission frequency band up to audio frequency 64.So most of uplink have the PSD that goes up being lower than of allowing-38dBm at whole upstream bandwidth (perhaps other values, from corresponding annex).Near the length restriction of the speed uplink of only trying hard to reach being directed against loop can use full power.The probability of the descending ADSL of one of these length-limit loops next-door neighbour can not determine performance characteristic or obtainable operational factor.On the contrary, upstream cut-off frequency can be used as the function of report adsl line and is programmed by dynamic controller (for example, the DSL optimizer) and adjust, and reaches its desired performance level up to these circuits.Obviously this frequency can rely on situation, and can dynamically be provided with according to quite simple program.Basically, only under following situation speed uplink will increase:

1---there are not other downstream systems report; And/or

2---system in future has the low probability of service disruption or problem.

This is the example of the reaction of the dynamic and on-fixed of another one, is reflected in the deployment the higher DSL speed of excitation significantly in then.According to the present invention, anyly want the ISP who operates in the speed higher that needs are followed the understanding to the accordance program than the current speed that allows.
