Description

具有自检功能的局端宽带设备及其检测的方法 技术领域 本发明涉及通信技术领域， 具体地说， 涉及一种局端宽带设备相关 检测的方法。
背景技术
随着网络技术的迅速普及以及多媒体技术的飞速发展， 用户 对带宽的要求越来越高。数字用户线路（ DSL， Digital Subscriber Line ) 技术在 2003年进入高速发展阶段， 非对称数字用户线路 (ADSL)和甚 高速数字用户线路（VDSL ) 的用户数量正在以迅猛的速度发展。 与 此同时， 宽带网络的测试和维护成为运营商头疼的问题， 特别是宽 带网络比起以前的传统窄带电信网要更加复杂， 技术含量更高， 因 此检测和维护更成为全球化的问题， 严重限制了宽带网络的发展。 目前， 市面上对宽带网絡进行仿真测试的系统都是单独的盒式测试 设备， 如图 1所示； 要求数字用户线路接入复用器 （DSLAM, Digital Subscriber Line Access Multiplexer )抓线 （断开 DSLAM的用户内线和 外线， 将内线和外线分別连接到测试总线上） 的同时， 将测试线交 给测试设备进行测试， 测试设备运用仿真模块对抓住的测试线发送
ADSL测试信号， 然后对测试得到的数据分析得到最后的结果， 并对测试 结果进行处理， 其方式有两种：
1、 给控制台显示分析， 这样就需要一台测试控制计算机， 而且需要 安装软件， 还需要由测试人员到设备所在地。
2通过网口将测试得到的数据发送到远端， 由远端分析处理， 同样， 需要一台安装了专门软件的测试控制和显示计算机， 同时需要独立的公 网 IP地址。
为此带来了以下问题：
1 ) 需要增加专门的测试设备， 增加建网成本以及组网难度； 2 ) 现有的测试设备昂贵， 尤其对于一些县、 乡地区， 用户比较 分散， 且几乎不可能接受如此昂贵的测试系统； 3 ) 用测试设备检测， 需要专用软件和计算机处理显示测试结果， 或支持远程测试， 需要给测试设备分配公网 IP地址， 占用相关资源； 而 且， 成千上百的 DSL用户故障申 4艮， 维护工作量大， 可能难以及时 处理且运营费用高昂；
4 )只能测试 ADSL端口， 而不能测试 VDSL端口； 否则需要再增加
VDSL的测试设备；
5 ) 测试操作复杂。
发明内容
本发明所要解决的技术问题是： 在不增加专门测试设备的前提下， 利用自身局端宽带设备对端口故障做出快速的定位和判断， 从而降低运 营商的维护、 运营成本。
本发明提供的一种具有自检功能的局端宽带设备， 包括若干个 XDSL 局端端口； 设置有至少一个控制开关组， 所述 XDSL局端端口通过所述控 制开关组与连接远端用户设备的外线相接；
所述控制开关组根据所述局端宽带设备发出的控制信号， 连接或断 开所述 XDSL局端端口中的任意端口， 以使所述 XDSL局端端口中的任意两 个端口连接的所述外线互相交换。
所述的控制开关组釆用继电器组或模拟开关组。
所述的 XDSL局端端口可以是 ADSL局端端口或 VSDL局端端口。
根据本发明还提供一种采用如权利要求 1所述的局端宽带设备进行 检测的方法， 包括步骤：
根据用户申报的故障信息中携带的故障线路编号， 查找该线路编号 与所述局端端口的对应关系， 确定故障线路在所述局端宽带设备中的具 体端口位置；
查找并确认一个当前没有业务流的正常端口；
根据局端宽带设备内控制信号， 控制连接在局端端口与外线之间的 所述控制开关组断开或闭合， 用所述正常端口替换所述故障端口， 对所 述故障端口原来外接的用户驻地设备进行测试， 从而判断是所述故障端 口自身的故障还是用户侧的故障。 根据局端宽带设备内控制型号， 控制连接在局端端口与外线之间的 所述控制开关组断开或闭合并用所述正常端口替换所述故障端口， 包括： 控制所述控制开关组， 将所述故障端口与连接用户驻地设备的外线 断开；
用所述正常端口连接所述外线；
所述局端宽带设备下发激活命令， 用所述正常端口激活原来与故障 端口连接的用户驻地设备。
当所述正常端口连接所述第一外线后， 能够激活原来与所述故障端 口连接的用户驻地设备， 则判断为故障端口自身的故障； 否则判断为线 路故障或用户侧的故障。
由于本发明只是在现有局端宽带设备的基础上加以改进， 使改进后 的局端宽带设备能对自身端口故障做出快速的定位和判断 , 无需增加专 用测试系统以及任何硬件设备， 因此节省资源、 极大地降低了组网和运 营成本； 由于操作人员可以在局方或远程控制操作， 无需再到设备所在 地， 因此节省了大量时间和人力， 从而降低了网络维护成本； 又由于局 端宽带设备自身既有 ADSL端口又有 VDSL端口，因此既可以找到好的 ADSL 端口又可以找到好的 VDSL端口去测试故障端口的用户驻地设备 ( CPE )。 附图说明
图 1为利用现有局端宽带设备加测试系统的组网图；
图 2为现有设备内 ADSL/VDSL CO端口与用户 MODEM的连接示意； 图 3为本发明设备内 ADSL/VDSL CO端口与用户 MODEM的连接示意。 具体实施方式
下面根据附图和实施例对本发明作进一步详细说明。
首先要对现有局端宽带设备进行改进， 使现有局端宽带设备成为具 有自检功能的设备。 图 2所示， 现有局端宽带设备中， 每个局端 （CO ) 端口通过外线直接与远端用户的 MODEM连接， 并且这个连接是——对 应并且固定的， 即 CO端口 P1只能与外线 Linel连接的 MODEM相连， 并依次类推。 改进后的设备如图 3所示， 包括有若干个 ADSL局端端口 或若干个 VDSL局端端口； 在 CO端口与连接远端用户 MODEM的外线 之间设置至少一个控制开关组 50, 使 ADSL /VDSL的各局端端口通过所 述控制开关组与外线相接， 控制开关组可以采用继电器组或模拟开关组； 通过设备内控制系统提供的控制命令， 使继电器组或模拟开关组动作， 就能将所述 ADSL/VDSL局端端口中的任意端口断开， 并将 ADSL局端 端口中任意两个端口连接的外线互换， 或将 VDSL局端端口中任意两个 端口连接的外线互换。 例如， H没图 3所示的 CO端口 1和 CO端口 2 都是 ADSL端口， CO端口 1和 CO端口 2经继电器组分别接外线 1和外 线 2， 当设备内控制系统下达一控制命令给继电器组时， 可以使 CO端口 1与外线 1断开， CO端口 2与外线 2断开， 并使 CO端口 1连接外线 2, CO端口 2连接外线 1。
改进后的局端宽带设备就能对自身端口发生故障的现象进行检测， 并对发生故障的具体原因做出定位和判断。 检测及定位方法包括以下基 本步骤：
A、根据用户申报的故障信息中携带的故障线路编号， 查找该线路编 号与所述局端端口的对应关系， 确定故障线路在所述局端宽带设备中的 具体端口位置， 并将该端口称为故障端口； 而引起故障的原因可能是端 口自身的故障， 也可能是用户侧的故障， 用户侧的故障包括线路故障和 用户 CPE故障；
B、局方维护人员在控制台上查找并确认一个当前没有业务流的正常 端口；
C、 根据设备内控制系统的命令， 使连接在局端端口与外线之间的控 制开关组动作， 即断开或闭合， 用已确认的正常端口替换所述故障端口 去测试该故障端口原来外接的用户驻地设备， 从而判断是端口自身出现 的故障还是用户侧的故障。
步骤 C具体包括如下步驟：
Cl、 控制所述控制开关组， 将所述故障端口与连接用户驻地设备的 第一外线断开， 以及将所述正常端口与连接用户驻地设备的第二外线断 开；
C2、 用所述正常端口连接所述第一外线； C3、 设备内控制系统下发激活命令， 用所述正常端口激活原来与故 障端口连接的用户驻地设备， 当所述正常端口连接所述第一外线后， 能 够激活原来与所述故障端口连接的用户驻地设备， 则是故障端口自身的 故障； 当所述正常端口连接所述第一外线后， 仍然不能激活原来与所述 故障端口连接的用户驻地设备， 则是线路或用户 CPE故障。
在有些电信运营商的 XDSL规范中， 要求局端宽带设备 ( DSLAM ) 具有抓线功能， 为本发明的实现提供了硬件保证。
与现有技术相比， 釆用本发明的技术方案无需另加任何硬件设备， 只 是利用已有的设备本身 ADSL/VDSL端口， 通过控制开关将故障端口的 CPE接到一个已知的 CO端口， 用正常的 CO端口去激活故障的端口连接的 CPE; 对于测试端口来说， 只是像正常业务流程一样去激活被测的 CPE同 时得到数据， 如果成功激活故障端口连接的 CPE, 则基本判定是端口本身 故障， 如果仍然不能激活， 则更大的可能是线路或用户 CPE错误。
由于正常工作的端口在 DSLAM设备上可以轻松查询到， 所以可以保 证测试端口本身没有问题的。
由于 DSLAM网络定位于边缘设备， 大多不在中心机房， 尤其在一些 县、 乡村， 存在机房环境较差的情况， 在加上北方的灰尘颗粒、 南方的 潮湿， 都可能导致单板短路而个别端口故障， 利用本发明可以迅速定位 端口故障的问题。
根据目前统计， 一旦已经开通的 XDSL业务， 用户申报的故障为非线 路故障， 而是端口故障或 CPE设置故障，本技术方案可以快速定位端口故 障或用户侧故障。
既能检测 ADSL端口又能检测 VDSL端口； 由于局端宽带设备自身 既有 ADSL端口又有 VDSL端口， 因此既可以找到好的 ADSL端口又可 以找到好的 VDSL端口去测试故障端口的用户驻地设备 ( CPE )。
综上所述， 本发明提供了一种既不用增加设备成本， 又可以快 速定位用户故障的解决方案， 这是全球运营商翘首企盼的事情， 因 此， 本发明技术方案所带来的效果和意义是时分显著和重大的。
可以理解， 对本领域普通技术人员来说， 可以根据本发明的技 术方案及其发明构思进行等同替换或改变， 而所有这些改变或替换 都落入本发明所附的权利要求的保护范围。
