产品特点:即插即用,传输距离远。功能丰富,支持多种互联网继而方式。
458-3SL紧凑型产品具备易使用的特点,特别适用于仅需要进行一至三个信道操作的研发工作场合。同时,对于需要在大量生产的产品线环境下进行DSL Modem和其它适应宽带的电信产品测试的情况,配备了Multi-Channel用户线仿真模块的Telebyte 458-3SL也不失为一个完*的解决方案。
通过458-3SL内置控制模块的IEEE 488接口、RS-232接口或以太网接口,在PC或其它终端上既可以利用图形化的软件也可以使用开放的用户命令语言对线路仿真模块进行环路长度及其它参数设置的控制。当然,458-3SL也可以作为*立操控的设备来使用,显示在前面板背光液晶屏上的模拟线路长度及其它参数可以通过按键编码器来进行设置。
Telebyte's 458 line modules simulate several cable types and offer the bandwidth requirements for today's xDSL technologies such as varieties of G.SHDSL, ADSL, ADSL2+ and VDSL2. Line lengths and configuration settings appear on an LCD display on the front of the unit and can be set via a keypad. We also offer other modules that work with our 458-CC-16/458-CM including the 458-SM-2-16 Transparent Switching Module.
