    • A DSL communication apparatus with lifeline functionality is provided, the DSL communication apparatus (3) in particular being suitable for CVoDSL (“Channelized Voice over Digital Subscriber Line”) transmission. The DSL communication apparatus (3) comprises a central processing unit (11) which detects a local power failure state of a local power supply unit (23) being associated with the DSL communication apparatus (3). In this case, the central processing unit (11) changes the operation of the DSL communication apparatus (3) from a normal operation mode to an intermediate operation mode, generates an interrupt for stopping a voice coprocessor unit (8), initializes a download of a lifeline operation firmware from a FLASH memory (12) to the voice coprocessor unit (8), and then starts a new initialization of the voice coprocessor unit (8). Thereafter, the central processing unit (11) changes the operation of the DSL communication apparatus (3) from the intermediate operation mode to the lifeline operation mode by switching the power supply of the DSL communication apparatus (3) from the local power supply unit (23) to an auxiliary power supply unit (20) being coupled to the transmission line (1).
    • 提供具有救生线功能的DSL通信装置,DSL通信装置(3)特别适用于CVoDSL(“信道化语音数字用户线路”)传输。 DSL通信装置(3)包括检测与DSL通信装置(3)相关联的本地电源单元(23)的本地电源故障状态的中央处理单元(11)。 在这种情况下,中央处理单元(11)将DSL通信设备(3)的操作从正常操作模式改变为中间操作模式,生成用于停止语音协处理器单元(8)的中断,初始化 从闪速存储器(12)到语音协处理器单元(8)的救生线操作固件,然后开始语音协处理器单元(8)的新的初始化。 此后,中央处理单元(11)通过从本地电源单元(3)切换DSL通信设备(3)的电源来将DSL通信设备(3)的操作从中间操作模式改变为生命线操作模式 23)连接到耦合到传输线(1)的辅助电源单元(20)。

    • There is provided an apparatus and method for ATM bonding. The apparatus comprises a first unit having a first xDSL line connected thereto, a second unit having a second xDSL line connected thereto and a connection between the first unit and the second unit. The first unit is arranged to convert one incoming ATM datastream to a plurality of data and to convert a plurality of incoming data to one ATM data stream. The first unit is arranged to implement the ATM bonding layer of the ATM protocol. The second unit may be arranged to implement one or more of the higher layers. The method comprises the steps of: a first unit receiving an ATM data stream; the first unit converting the ATM data stream into a plurality of data; the first unit transmitting a first one of the plurality of data over a first xDSL line connected to the first unit; the first unit sending a second one of the plurality of data to a second unit via a connection; and the second unit transmitting the second one of the plurality of data over a second xDSL line connected to the second unit.
    • 提供了一种ATM绑定的装置和方法。 该装置包括具有连接到其上的第一xDSL线的第一单元,具有连接到其上的第二xDSL线的第二单元和第一单元与第二单元之间的连接。 第一单元被布置成将一个输入的ATM数据流转换成多个数据并将多个输入数据转换成一个ATM数据流。 第一单元被布置成实现ATM协议的ATM绑定层。 第二单元可以被布置成实现一个或多个较高层。 该方法包括以下步骤:接收ATM数据流的第一单元; 第一单元将ATM数据流转换成多个数据; 所述第一单元通过连接到所述第一单元的第一xDSL线发送所述多个数据中的第一数据; 所述第一单元经由连接将所述多个数据中的第二数据发送到第二单元; 并且所述第二单元通过连接到所述第二单元的第二xDSL线发送所述多个数据中的第二数据。
