In addition, there are two strands of the head is also black, and are rust, rust can be seen because of lead wire resistance increases, resulting in the signal can not be smooth, telephone through the audio signal, the low band signal can also only phone, there is always the voice of flap, and the use of the ADSL band signal is relatively high, head through the rust on it is very difficult, leading to slow or stop signal transmission.

此外有两处绞合的线头处也发黑了，都是锈，可见正是因为导线生锈导致电阻增大，导致信号不能畅通，电话通过的音频信号，频带低，信号还能通过，只是电话里老是有啪啪的声音，而ADSL的信号使用的频带比较高，线头生锈了就很难通过，导致信号传输变慢或者断流。
