输出频率可在中心频率(56.448兆赫)附近连续微调。调整范围为65千赫。

Its output frequency can be adjusted continuously around the center frequency (56.448 MHz) over a range of 65 KHz.

许多已有的CO(中心局)dsl调制解调器可以只支持相对较窄的接收频率范围，这会增加估计宽的多的远端环路噪声的难度。

Many existing CO DSL modems may only support a relatively narrow receive frequency range, which will increase the difficulty of estimating the much wider bandwidth far-end loop noise.
