Definitions

  • xDSL is a collective term for DSL (Digital Subscriber Line), which is a point-to-point transmission technology using a copper telephone line as a transmission medium.
  • DSL technology supports symmetric and asymmetric transmission modes on the traditional POTS (telephone network) subscriber loop, solving the transmission bottleneck problem that often occurs in the last mile between network service providers and end users. Because xDSL utilization already exists The copper resources provide high-bandwidth services, effectively protect operators' investments, provide broadband services to customers, and are therefore thriving around the world.

So far, more than 50 million users around the world have enjoyed the high-speed Internet access, video services and other multimedia services brought by ADSL.

Description

通讯装置及节省通讯装置静态功耗的方法
技术领域 本发明涉及通讯领域， 尤其涉及一种通讯装置及节省通讯装置静态功耗的方法。 发明背景 xDSL是 DSL (Digital Subscriber Line, 数字用户线） 的统称， 是以铜电话线为传 输介质的点对点传输技术。 DSL技术在传统的 POTS (电话网络） 的用户环路上支持对称 和非对称传输模式，解决了经常发生在网络服务供应商和最终用户间的 最后一公里"的 传输瓶颈问题。 由于 xDSL利用已有的铜线资源提供高带宽的业务， 能够有效地保护运营 商的投资， 为客户提供宽带业务， 因此在全球各地得到蓬勃发展。
ADSL (非对称数字用户线）是 xDSL中的一种， ADSL非常适合个人宽带接入业务的数 据流量非对称的特点， 即下行方向 （从 CO (局端） 到 CPE (用户端） ) 的数据量远大于 上行 （从 CPE到 CO)方向的数据量， 因此， ADSL在个人用户宽带接入应用方面占据绝对 优势。 到目前为止， 全球共有超过 5000万的用户享受着 ADSL带来的高速上网、视频业务 等多媒体业务， ADSL业务提供商据此在双绞线上挖出了 "新的金矿"， 成为除 POTS以外 的又一个重要收入来源。
随着用户对带宽接入需求的进一步增加，一种能提供更高的带宽以及更灵活分配上 下行带宽的接入技术， 即 VDSL (甚高速数字用户线）技术将得到应用。 另外一种广泛使 用的 DSL技术称为 G. SHDSL (对称高速 DSL)， G. SHDSL因为能提供对称的业务而被更多地 用于商业用户。
ADSL, ADSL2+ (第二代的 ADSL)以及 VDSL都使用比传统电话信号频带（3. 4KHz以下） 更高的频率， 其中 ADSL的频带范围为 25. 875KHz〜1104KHz， ADSL2+则使用 25. 875KHz〜 2208KHz的频带范围， VJDSL有可能使用从 25KHz〜30MHz的频带。 由于 xDSL与 P0TS业务使 用不同的频带， 因此它们可以在同一条电话线上传输， 只需要在电话线的两端收发器中 使用简单的滤波器就可以将二者分开。 ADSL或 VDSL的***参考模型如图 1所示， 在提供 ADSL或 VDSL业务的通信***中这种滤波器又称为 Splitter (分离器） ； 在该***中， 还 需要设置一种能够集中提供多路 ADSL或 VDSL业务的设备， 该设备称为 DSLAM (DSL接入复 用器） 。
随着 xDSL应用规模的急剧扩大， xDSL的线路规模数量迅速向 P0TS线路接近， 最终将 会接近 1： 1的规模， 如果此时仍采用如图 1所示的网络模式将会大大增加建网的复杂度、 难度及维护成本。 因此， 各个大的运营商已经幵始采用一种新的建网模式， 即 IVD (语 音数据集成） 的建网模式。
相应的 IVD的建网***参考模型如图 2所示， 其结构主要包括在 MSAN (多业务接入节 点） 中设置有 IVD单板， 所述的 IVD单板包括： xTU- C (xDSL局端单元） 、 POTS (传统电 话业务）处理单元和 LPF (低通滤波器） ,从而使得 IVD单板能够同时支持 xDSL业务的 POTS 的传输处理。 可以看出采用 IVD建网具有一系列的优势， 如： 采购成本低、 建网复杂度 低、 维护成本低等， 因此， IVD将会成为下一代网络的主流模式。 但同时 IVD也带来了一 系列的难点及问题， 其中一个是设备的功耗问题， 尤其是在建网的初期， 在 XDSL线路使 用率还很低的时候， 这个问题更加突出。
下面将具体分析图 1所示的网络结构和图 2所示的网络结构所存在的问题- 在图 1中， DSLAM采用了集中复用的模式， 可以随着用户数量的增长来逐步增加设备 的密度， 因此， DSLAM的设备平均利用率比较高， 相对的功率损失较小， DSLAM的建网模 型中建网规模和端口利用率的示意图如图 3所示；
在图 2中， MSAN (多业务接入节点） 的 IVD建网模式需要一次性将所有的宽带随窄带 端口一次性部署完毕， 在建网初期， 宽带用户同窄带用户比例相比较低的情况下， 宽带 部分的功率损失相对较高， IVD的建网模型中建网规模和端口利用率的示意图如图 4所 示。 从图 4可以看出， 在 IVD的建网模型的建网初期， 静态功耗是比较大的。 例如， 对于 典型的 32ch IVD来讲， 32ch POTS的静态功耗一般在 3W左右， 而 32ch ADSL在不开通的条 件下， 静态功耗接近 10W, 极限情况下 IVD作为纯 POTS使用， 功率损耗是 PSTN设备功 率损耗的 400%左右。 因此， 对于运营商整网来讲， 相应的功率损耗太大， 明显与节能 设计的目标相违背。
为此， 目前提供了相应的降低功率损耗的实现方式， 现有技术中针对 XDSL线路的节 省功率减少功耗的实现方法包括： L2/L3低功耗模式的应用； Power management (端口 功率管理） ； Power cutback (功率削减）等方法。
不难看出， 上述现有技术的 XDSL线路的节省功率的方法的缺点为： 上述所有方法都 是在关注 xdsl线路已经开通的条件下的节省功率的问题，而对于 XDSL线路未开通时的静 态功率损耗问题并没有提供可行的解决方案。 发明内容

以本发明应用于 IVD单板中为例，具体可以在 IVD单板或单板中的独立的模块的电源 入口处设置电源控制电路， 通过该电源控制电路， 在需要时将 IVD单板的宽带部分或窄 带部分关闭， 以节省 IVD单板的静态功率。 当然， 本发明不仅限于应用于 IVD单板中， 也 可以应用于其他类似的通讯设备中， 以实现降低静态功耗的目的。
下面结合附图来详细描述本发明， 本发明所述通讯装置的具体实现结构图如图 5所 示， 主要包括控制信号单元和电源控制电路单元， 且-
( 1 ) 所述的控制信号单元， 用于向电源控制电路单元传递关闭通讯装置中部分业 务单元的电源的控制信号， 以便于控制将部分业务单元的电源关闭， 从而节省整个通讯 装置的静态功耗；
该控制信号单元进一步可以包括： 外部控制信号单元和 /或内部控制信号单元， 其 中， 外部控制信号单元： 用于接收来自通讯装置外部的控制信号， 将接收到的所述控制 信号传递给电源控制电路单元；

以本发明应用于 IVD单板为例， 相应的电源控制电路单元可以设置在单板内部的宽 带电路模块和 /或窄带电路模块的电源输入点处， 具体包括以下几种上实现方案-
( 1 )仅在宽带电路模块电源输入点设置电源控制电路；
(2)仅在窄带电路模块电源输入点设置电源控制电路；
( 3) 同时在宽、 窄带电路模块电源输入点都具有电源控制电路。
当采用上述（1 )和 （3 ) 的实现方案时， 在宽带电路模块电源输入点设置电源控制 电路时，其引入的控制信号可以来源于窄带电路模块或单板内部其他独立供电的模块电 路 (包含宽带内部独立供电的模块电路)，通过窄带电路模块或单板内部其他独立供电的 模块电路 (包含宽带内部独立供电的模块电路)输出的控制信号可以将宽带部分电路的 全部或部分电源关闭来节省静态功耗；
当采用上述（2)和 （3) 的实现方案时， 在窄带模块电源输入点设置有电源控制电 路时， 其引入控制信号可以来源于宽带模块电路或单板内部其他独立供电的模块电路 (包含窄带内部独立供电的模块电路)，通过宽带电路模块或单板内部其他独立供电的模 块电路 (包含窄带内部独立供电的模块电路)输出的控制信号可以将窄带部分电路的全 部或部分电源关闭来节省静态功耗；
其中， IVD单板内部的宽带电路模块是指： ADSL/ADSL2/ADSL2+/VDSL/VDSL2/G. SHDSL 等业务模块； 工 VD单板内部的窄带电路模块是指： POTS/ISDN等电路模块。
以 IVD单板为例 （但本发明并不仅限于应用于 IVD单板中）， 本发明所述方法的具体 处理流程图如图 6所示， 包括如下步骤：
步骤 6- 1、 在 I VD单板电源入口处设置电源控制电路；
所述的电源控制电路包括控制信号单元和电源控制电路单元，各单元具体完成的功 能及作用前面已经描述， 在此不再详述；
本发明首先需要在 IVD单板的宽带电源入口处和窄带电源入口处分别增加一个电源 控制电路， 其中， 在宽带电源入口处增加的电源控制电路可以将宽带,部分的电源关闭， 在窄带电源入口处增加的电源控制电路可以将窄带部分的电源关闭。
步骤 6- 2、 给电源控制电路设置可以引入不同来源的控制信号。
在给 IVD单板电源入口处增加了电源控制电路后， 本发明给该电源控制电路的控制 信号的来源设计了三种实现方式 - 第一种实现方式为控制信号来源于单板外部，如来源于***控制模块或其它监控模 块， 该***控制模块或其它监控模块通过背板将控制信号传递给电源控制电路。控制信 号 conl、 con2来源于单板外部的 IVD单板电源功率电路示意图如图 7所示， 图中的第一个 电源控制电路 Power Con Cirl引入的控制信号为 conl , 第二个电源控制电路 Power Con Cir2引入的控制信号为 COn2。 例如， 通过背板输入的控制信号可以将宽带部分电路、 窄 带部分电路的全部或者部分电源关闭来节省静态功耗，背板输入控制信号可以来源于系 统主控板、 ***监控板、 其他公共管理模块或其他公共监控模块等； ***主控板、 *** 监控板、 其他公共管理模块或其他公共监控模块等可以接受主机命令行、 NMS (网络管 理***） 图形界面等管理软件***的控制， 通过主机命令行、 NMS图形界面等管理软件 ***可以实现针对宽带电路模块部分等业务单元的功率控制， 即控制宽带电路模块等业 务单元的电源输入点的电源控制电路是否为宽带电路模块等业务单元供电。
第二种实现方式为控制信号来源于单板内部不同的模块电路， 即宽带部分的电源控 制信号来源于窄带部分， 窄带部分的电源控制信号来源于宽带部分， 此时， IVD单板电 源功率电路示意图如图 8所示。 或者宽带部分、 窄带部分的电源控制信号都来源于单板 内部同一个独立的管理模块， 此时， IVD单板电源功率电路示意图如图 9所示。 在图 8和 图中， 第一个电源控制电路 Power Con Cirl引入的控制信号为 conl , 第二个电源控制电 路 Power Con Cir2引入的控制信号为 con2， 而且， 在图 9中所述的独立的管理模块为设 置有管理端口 Management Port的电源控制模块 Power Con Model。
第三种实现方式为控制信号来源于板内机械开关或跳线， 此时， 工 VD单板电源功率 电路示意图如图 10所示， 同样， 图中的第一个电源控制电路 Power Con Cirl引入的控制 信号为 ccml , 第二个电源控制电路 Power Con Cir2引入的控制信号为 COn2， 且相应的控 制信号来自于交换开关 on- off Switcho
本发明中，至少可以选择上述三种控制信号的来源中的一种作为所述电源控制电路 引入的控制信号的来源。
步骤 6- 3、利用设置的电源控制电路和可以引入的控制信号给 IVD单板配置不同的运 行模式。 ，
在上述图 7至图 10中， - 48VI是宽带部分的电源输入， 该输入通过 DC (直流） /DC转 换成宽带电路所需电源。 第一个电源控制电路 Power Con Cirl是宽带电源输入的控制电 路， 来源于上述三种实现方式的控制信号通过此电路可以将宽带部分的电源关闭， 避免 宽带电路的静态功率损耗；
- 48VII是窄带部分的电源输入， 该输入为 P0TS馈电电路提供高压电源。第二个电源 控制电路 Power Con Cir2是窄带部分的电源输入控制电路， 来源于上述三种实现方式的 控制信号通过此电路可以将窄带部分的电源关闭。避免窄带部分的静态功率损耗。 Power Con Cirl和 Power Con Cir2相互独立。
在上述图 7至图 10所示的 IVD单板电路中， 可以根据实际需要， 将 IVD单板的宽带部 分或窄带部分关闭， 即可以利用设置的电源控制电路和控制信号给 IVD单板配置不同的 运行模式。 IVD不同的运行模式同电源控制电路的逻辑关系的关系示意图如图 11所示。
如图 11所示， 当 IVD单板工作在 POTS Only Mode模式下时， 可以节省功率约 70%， 而当 IVD单板工作在 ADSL ONLY模式下时， 可以节省约 30%的功率损耗。 步骤 6- 4、 NMS (网络管理***）利用所述的电源控制电路实现针对不同的 IVD单板 进行集中管理。
在本发明中， 可以由 NMS通过控制传递给所述的电源控制电路的控制信号对不同的 IVD单板进行集中管理。 即 NMS可以依据不同的 IVD单板的用户端口占用的不同比例， 来 给不同的 IVD单板配置不同的工作模式比例， 通过集中管理可以降低整个网络的功率浪 费。该集中管理的示意图如图 12所示， 在图 12中可以简单预计不同模式下 MSAN的静态功 率耗散， 在最大情况下可以节约 70 %以上的功耗。
本发明所述方法同样可以应用于其他模块、 单板或者设备。
以上所述， 仅为本发明较佳的具体实施方式， 但本发明的保护范围并不局限于此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易想到的变化或替 换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护范围应该以权利要求的保 护范围为准。
