以太网信号可以是快速以太网( FE, Fast Ethernet M言号或千兆以太网( GE,
Gigabit Ethernet )信号。 本发明实施例以应用于 FE信号为例对该方法进行分 析说明, 不构成对本发明的限定。
可以理解的是, FE信号是高频信号, 其功率谱密度所在的频谱范围分布 比较宽, 大概范围在 0Hz ~ 125MHz之间, 而其主要能量集中在 30MHz以下。 POTS信号是低频信号,其功率谱密度所在的频谱范围集中在 25KHz以下。 因 此,本实施例可以将这两个信号频谱及功率谱密度差异较大的 FE信号和 POTS 信号耦合, 得到耦合信号, 使得 FE信号和 POTS信号可以共线传输。
可以理解的是, 传输 POTS信号的回路的馈电和振铃电压较高, 其中, 馈 电电压通常在 48V左右,振铃电压通常在 90V左右, 而传输 FE信号的回路的 电压较低, 馈电和振铃电压较高的回路中传输的 POTS信号可能会损坏 FE信 号。
进一步地, 为了在 FE信号和 POTS信号耦合时, 防止 FE信号被损坏, 更好的保证 FE信号和 POTS信号的耦合质量, 可以对以太网信号进行隔直处 理后再与 POTS信号耦合。 例如, 通过在传输所述以太网信号的回路上设置的 电容来对所述以太网信号进行隔直处理, 使得 FE信号不被馈电和振铃电压较 高的 POTS信号损坏。
进一步地, 由于 POTS信号是低频信号, FE信号是高频信号, 为了避免 在耦合时 FE信号反灌回来影响 POTS信号, 在某些实施方式中, 可以在耦合 之前对 POTS信号进行低通滤波处理。 具体的, 可以在传输 POTS信号的回路 中设置一个低通滤波器, 例如, 本实施例的该低通滤波器可以选择分离器 ( SPL, Splitter )„ SPL能通过低频的 POTS信号, 而高频的 FE信号则几乎不 能通过, 因此能避免 FE信号反灌回来影响 POTS信号。
在某些实施方式中, 可以将隔直后的 FE信号与滤波后的 POTS信号直接 线与, 完成 FE信号与 POTS信号的耦合。
步骤 102、 通过一个通道将该耦合信号共线传输发送出去;
由步骤 101可知, FE信号和 POTS信号耦合后得到的耦合信号可以共线 传输, 可以将该耦合信号通过一个通道发送给用户侧, 即将 FE信号和 POTS 信号传输到用户侧只需要通过一个通道, 节省了通道资源。 其中, FE信号需 要两对线承载, POTS信号需要一对线承载, 那么, 只需要两对线就可以将该 耦合信号发送到用户侧。
若采用五类线入户, 由于 FE信号最少需要使用 2对线承载, POTS信号 需要 1对线承载, 而五类线有 4对线, 那么, 本发明实施例中最多可以同时传 输 2*FE+4*POTS, 即 2个 FE信号和 4个 POTS信号, 因此可以保证提供两个 FE口和至少一个 POTS口, 使得本发明可以同时支持数据、 视频和话音业务, 保证了网线入户场景下提供 e8/e9业务套餐能力。
此外, 也可以最多同时提供 2*FE+2*POTS+PoE, 其中, PoE信号可以是 正向信号或反向信号, 满足了用户的多种需求。
请参阅图 2, 图 2是数据传输过程的示意图。 如图 2所示, 一根 8芯的网 线可以承载 2*FE+4*POTS, 即 2个 FE信号和 4个 POTS信号,可以同时提供 数据、 视频和话音业务, 提高了用户体验。
在某些实施例中, 若该以太网信号是 GE信号, 其具体实施与 FE信号的 实施同理,由于 GE信号需要 4对线来承载,因此最多可以传输 l*GE+4*POTS 或 l*GE+2*POTS+PoE。
可以理解的是, 本发明实施例还可以应用在其他场景, 例如, 可以应用在 VDSL2/G.fast信号、 E1信号、 语音信号、 远供电源和反向供电等信号在同轴 或双绞线上的混合承载等, 具体不再本发明中赘述。
由上可知,本发明实施例将以太网信号与语音业务 POTS信号耦合并通过 一个通道将所述耦合信号共线传输发送出去, 节省了传输通道, 并且本发明实 施例可以同时支持宽带业务和话音业务, 满足了用户的多种需求,提高了用户 体验。
耦合信号传输到用户侧后, 用户可以将该耦合信号解耦和, 分別得到以太 网信号和 POTS信号, 以供用户使用。
有鉴于此, 本发明实施例还提供了一种数据的传输方法, 本实施例将以数 据的传输装置的角度对该方法进行描述,本发明实施例以该数据的传输装置为 在用户侧为例进行详细说明, 不构成对本发明的限定。
请参考图 2, 为本发明实施例提供的一种数据的传输方法可包括以下步 骤:
步骤 201、 接收耦合信号, 所述耦合信号为以太网信号与语音业务 POTS 信号耦合后通过一个通道共线传输过来的信号;
以太网信号可以是快速以太网( FE, Fast Ethernet M言号或千兆以太网( GE, Gigabit Ethernet )信号。 本发明实施例以应用于 FE信号为例对该方法进行分 析说明, 不构成对本发明的限定。 由上述实施例可知, 网络侧可以将由 FE信号和 POTS信号耦合得到的耦 合信号通过一个通道发送给用户侧,用户侧接收该通过一个通道共线传输过来 的耦合信号。
步骤 202、 解耦和该耦合信号, 分別得到以太网信号和 POTS信号。
用户侧接收到该耦合信号后, 对该耦合信号进行解耦合。
进一步地, 解耦和该耦合信号, 分別得到以太网信号和 POTS信号, 具体 可以包括: 对所述耦合信号进行低通滤波处理, 得到 POTS信号; 对所述耦合 信号进行割直处理, 得到以太网信号。
其中, 解耦和的过程与耦合同理, FE信号是高频信号, POTS信号是低频 信号, 因此可以在对 FE信号和 POTS信号解耦合后, 对 FE信号进行隔直处 理和对 POTS信号进行低通滤波处理。 例如, 在传输 POTS信号的回路中设置 一个低通滤波器, 其中, 该低通滤波器可以是分离器(SPL, Splitter ), 由于 SPL能通过 频的 POTS信号, 而高频的 FE信号则几乎不能通过, 因此可以 很好的将 FE信号和 POTS信号分离。 而为了防止 FE信号被损坏,保护 FE信 号不被馈电和振铃电压较高的 POTS信号损坏,可以在传输以太网信号的回路 上设置电容以进行割直处理。
由于 FE信号需要两对线承载, POTS信号需要一对线承载, 该耦合信号 是通过两对线发送给用户侧, 若采用五类线入户 , 可以同时传输 2*FE+4*POTS,即 2个 FE信号和 4个 POTS信号, 因此可以保证提供两个 FE 口和至少一个 POTS口, 使得本发明可以同时支持数据、 视频和话音业务, 保 证了网线入户场景下提供 e8/e9业务套餐能力。
此外, 也可以最多同时提供 2*FE+2*POTS+PoE, 其中, PoE信号可以是 正向信号或反向信号, 满足了用户的多种需求。
在某些实施例中, 若该以太网信号是 GE信号, 其具体实施与 FE信号的 实施同理,由于 GE信号需要 4对线来承载,因此最多可以传输 l*GE+4*POTS 或 l*GE+2*POTS+PoE。
由上可知,本发明实施例将以太网信号与语音业务 POTS信号耦合得到的 耦合信号进行解耦和后供用户使用, 节省了传输太网信号与 POTS 信号的通 道, 并且可以同时支持宽带业务和话音业务, 满足了用户的多种需求, 提高了 用户体验。
以上两个实施例是分別单独针对网络侧和用户侧进行的描述,在实际运用 中, 以上两个实施例可以结合在一起使双侧能对应处理。

下面将结合网络侧设备和用户设备对本发明实施例进行详细说明,请参阅 图 7 , 图 7 是本发明实施例中数据传输过程的结构示意图。 图 7 中以 l*FE+l*POTS的传输为例进行详细说明。
可以理解的是, FE信号通过 2对线传输, POTS信号通过 1对线承载。在 信号的传输过程中, 采用两对线发送 1个 FE信号, 采用两对线接收该 FE信 号。 其中, 可以在发送 FE信号的回路上与 POTS信号耦合, 也可以在接收 FE 信号的回路上与 POTS信号耦合。 例如, 在发送 FE信号的回路上与 POTS信 号耦合时, 采用 2对线发送 FE信号, 采用 1对线发送 POTS信号, FE信号和 POTS信号耦合后, 最多只需要 2对线传输该耦合后的信号。 图 7是以在发送 FE信号的回路上与 POTS信号耦合为例进行详细说明, 不构成对本发明的限 定。
本发明实施例中, 网络侧中在发送 FE信号的回路上设置电容, 将 FE信 号与 POTS信号进行隔离,并且在传输 POTS信号的回路上设置 SPL,对 POTS 信号进行低通滤波处理, 避免 FE信号对 POTS信号的影响, 然后将传输 FE 信号的回路与传输 POTS信号的回路耦合, 使得隔直后的 FE信号和低通滤波 后的 POTS信号耦合, 最多只需要通过两对线对该耦合信号进行传输, 当该耦 合信号传输到用户侧时, 用户同样对该耦合信号进行隔直处理和低通滤波处 理, 可以分別得到 1个 FE信号与 1个 POTS信号。
