高速銅纜共存系統與其自動設定方法 High-speed copper cable coexistence system and its automatic setting method

本發明係關於一種纜線系統及方法，特別為一種高速銅纜共存系統與其自動設定方法。 The present invention relates to a cable system and method, and more particularly to a high speed copper cable coexistence system and an automatic setting method thereof.

隨著電信業者持續積極佈建光纖網路到家，在最後一哩的光纖建設上面臨了成本、時效性、用戶意願等等議題。為了更具經濟效益提供高速寬頻上網服務，充分利用既存銅線之價值，縮短最後一段銅線的距離，以降低線路的衰減再輔以使用高頻帶之銅線接取技術，達到高頻寬之上網需求，因而逐漸衍生FTTdp(Fiber-to-the-distribution point)架構的應用概念。FTTdp主要是將FTTEx(Fiber-to-the-Exchange)、FTTC(Fiber-to-the-Curb)光纖再更往用戶端推進，光纖終點與銅纜起點的DPU(Distribution Point Unit)設備已非常接近用戶住家，例如放置樓層電信箱或大樓電信室，大幅縮短銅線距離以提升連線速率，DPU上行光纖介面可採用PON(Passive Optical Network)或是GE(Gigabit Ethernet)技術，DPU下行銅纜介面初期主要仍為VDSL2(Very-high-bit-rate digital subscriber line 2)，並採用向量(Vectoring)技術及綑綁(Bonding)技術來提高接取頻寬與距離，為了滿足電信業者提供高速服務之需求，ITU-T組織(ITU Telecommunication Standardization Sector，國際電信聯盟電信標準化部門)近來發展下一代的銅纜接取技術，以提供Gbps等級的頻寬，技術命名為”FAST(Fast Access to Subscriber Terminals)”，亦稱為G.fast技術，並於2014年完成G.9700與G.9701標準制定。電信業者以G.fast技術發揮最大可供裝距離在200公尺內作為考量，估計可能供裝之G.fast DPU位置有大樓樓層、用戶屋外(非大樓)、大樓電信室。其中大樓內因故(管道壅塞等因素)無法佈建光纖到用戶宅內，只能佈建到大樓電信室，位於大樓電信室的G.fast DPU設備透過大樓內的垂直及水平銅纜與用戶端設備相接，但此時大樓電信室已存在許多既有VDSL2數位線路接取器，因此如何整合既有VDSL2與新一代線路之共存，成為各方所研究之議題。 As telecom operators continue to actively build fiber-optic networks to the home, they face the issues of cost, timeliness, and user willingness in the final fiber construction. In order to provide high-speed broadband Internet service with more economic benefits, make full use of the value of existing copper wire, shorten the distance of the last copper wire, reduce the attenuation of the line and supplement the copper wire access technology with high frequency band to achieve high-frequency wide Internet access. Therefore, the application concept of the FTTdp (Fiber-to-the-distribution point) architecture is gradually derived. FTTdp mainly pushes FTTE (Fiber-to-the-Exchange) and FTTC (Fiber-to-the-Curb) fiber to the user side. The fiber end point is very close to the DPU (Distribution Point Unit) device of the copper cable starting point. The user can live in the home, for example, the floor telecommunications box or the building telecom room, which greatly shortens the copper distance to improve the connection speed. The DPU uplink optical interface can adopt PON (Passive Optical Network) or GE (Gigabit Ethernet) technology, and the DPU downlink copper interface. In the initial stage, VDSL2 (Very-high-bit-rate digital subscriber line 2) is still used, and vectoring technology and binding technology are used to improve the access bandwidth and distance, in order to meet the needs of telecom operators to provide high-speed services. , ITU-T organization (ITU Telecommunication The Standardization Sector (Telecommunication Standardization Sector of the International Telecommunication Union) has recently developed the next generation of copper access technology to provide Gbps-class bandwidth. The technology is named "FAST (Fast Access to Subscriber Terminals)", also known as G.fast technology. And in 2014 completed the G.9700 and G.9701 standards. The telecom operators use G.fast technology to maximize the available distance of 200 meters. It is estimated that the G.fast DPU location may be installed on the building floor, outside the user's house (non-building), and building telecom room. In the building, the fiber could not be built into the user's house due to factors such as pipeline congestion. It can only be built into the building's telecommunications room. The G.fast DPU equipment in the building's telecommunications room passes through the vertical and horizontal copper cables and the customer premises in the building. The equipment is connected, but at this time there are many existing VDSL2 digital line accessors in the building telecommunications room. Therefore, how to integrate the coexistence of the existing VDSL2 and the new generation lines has become the subject of research.

本發明之G.fast技術使用頻帶為2.2~106MHz，頻譜與既有VDSL2訊號有重疊之情況，G.fast電路輸出功率只有4dBm，遠小於VDSL2的14.5dBm，測試結果分析當VDSL2進行連線時將造成G.fast電路斷線，而G.fast進行連線未對G.fast電路造成影響，VDSL2與G.fast之頻譜分佈如圖1所示。因此，如圖2所示，為了保護G.fast電路訊號品質，最簡單方式為採用避頻方式，但G.fast因少掉VDSL2頻帶，而只能使用32M~106MHz，且當沒有VDSL2訊號或VDSL2因VDSL2訊號因距離衰減而頻帶限縮而沒有使用至30MHz，G.fast避頻方式則顯浪費。 The G.fast technology of the present invention uses a frequency band of 2.2 to 106 MHz, and the spectrum overlaps with the existing VDSL2 signal. The output power of the G.fast circuit is only 4 dBm, which is much smaller than the 14.5 dBm of the VDSL 2. The test result is analyzed when the VDSL 2 is connected. This will cause the G.fast circuit to be disconnected, and the G.fast connection does not affect the G.fast circuit. The spectrum distribution of VDSL2 and G.fast is shown in Figure 1. Therefore, as shown in Figure 2, in order to protect the signal quality of the G.fast circuit, the simplest way is to use the frequency avoidance mode, but G.fast can only use 32M~106MHz because there is no VDSL2 band, and when there is no VDSL2 signal or VDSL2 is not used because the VDSL2 signal is limited by the distance attenuation and is not used up to 30MHz. The G.fast frequency avoidance method is wasteful.

(1).共存系統內的VDSL電路 (1). VDSL circuit in the coexistence system

如圖6所示，為共存系統內VDSL電路之運作示意圖，G.fast+VDSL設備代表同一機房端設備內可提供G.fast電路與VDSL電路，例如機架型設備之同一卡板內提供G.fast埠或採VDSL fallback埠，或者不同卡板提供不同G.fast與VDSL。高速銅纜共存系統採用SNR，bitloading之carrier方法偵測VDSL電路頻譜分佈。假若VDSL2電路只提供低速電路，用不到較高頻帶，可設定該電路的使用頻譜(如8x profile)。 As shown in FIG. 6 , for the operation diagram of the VDSL circuit in the coexistence system, the G.fast+VDSL device represents G.fast circuit and VDSL circuit in the same equipment room end device, for example, G is provided in the same card board of the rack type device. .fast埠 or VDSL fallback埠, or different cards provide different G.fast and VDSL. The high-speed copper coexistence system uses SNR, bitloading carrier method to detect the spectrum distribution of the VDSL circuit. If the VDSL2 circuit only provides a low-speed circuit and does not use a higher frequency band, the spectrum of use of the circuit (such as 8x profile) can be set.

(2).共存系統外的既有VDSL電路 (2). Existing VDSL circuits outside the coexistence system

如圖7及圖8所示，為共存系統外之既有VDSL電路之運作以及群組外VDSL2判斷實例示意圖，偵測鄰路是否有VDSL訊號(取樣四次；N=4；每間隔時間T)，若無，則不考慮其他外在雜訊，若有，利用LDM記錄雜訊最大頻率點，並取多次以決定最大頻率點，取多次用意在於可刪除暫態之強雜訊。 As shown in FIG. 7 and FIG. 8 , it is a schematic diagram of the operation of the existing VDSL circuit outside the coexistence system and the VDSL2 judgment example outside the group, and detecting whether the neighbor has a VDSL signal (sampling four times; N=4; each interval time T) ), if not, do not consider other external noise, if any, use LDM to record the maximum frequency of the noise, and take multiple times to determine the maximum frequency point, take multiple times to remove the strong noise of the transient.

本發明之本發明之高速銅纜共存系統的自動設定方法智慧判斷原則如下： The wisdom judging principle of the automatic setting method of the high-speed copper cable coexistence system of the present invention of the present invention is as follows:

判斷1：監控高速銅纜共存系統內的VDSL電路，若有，利用SNR Bitloading等機制判斷出最大頻率點f1送至共存分析模組，若無，則持續監控 Judgment 1: Monitor the VDSL circuit in the high-speed copper coexistence system. If yes, use SNR Bitloading and other mechanisms to determine the maximum frequency point f1 to be sent to the coexistence analysis module. If not, continue to monitor.

判斷2：監控高速銅纜共存系統外的VDSL電路若有，每一段時間(例如T分鐘)利用G.fast電路迴路雜訊監控模組之LDM-QLN判斷最大頻率點出f2，共N次，將N次的最大頻率點f2送至共存分析模組，若無偵測到VDSL雜訊，則持續監控。 Judgment 2: If there is a VDSL circuit outside the high-speed copper cable coexistence system, use the LDM-QLN of the G.fast circuit loop noise monitoring module to judge the maximum frequency point f2 for a period of time (for example, T minutes). The maximum frequency point f2 of N times is sent to the coexistence analysis module, and if no VDSL noise is detected, the monitoring is continued.

判斷3：共存分析模組取f3=max(f1,f2)，頻譜設定模組將f3頻帶參數設定入G.fast電路之啟始頻帶。 Judgment 3: The coexistence analysis module takes f3=max(f1, f2), and the spectrum setting module sets the f3 band parameter into the starting band of the G.fast circuit.
