模擬的廣域網環境,可以很容易地對網絡帶寬、延遲、數據丟失、擁塞情況以及其他一些網絡損傷狀態進行模擬,在實驗室條件下實現對應用程序或網絡設備在各種網絡條件下的性能的測試。

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.
