请教布线问题...

<P>用大对数线缆布语音线，请问线缆到每层楼后，如何分一部分出来，其余的继续往上拉？需要什么设备吗?没施工过，所以一直没想明白具体该如何做！</P>

用网线通过PVC管通往各个点就行了。和网络信息点的线——也是网线，同时走。

现在有70多个语音点，内外线各30多个，那么是直接拉70多根线吗？

我理解，你说的办法是想把一根大对数缆分开，这样不行。不能用一根大对数缆向各层分。应该用小一点的对数缆分别布向各层（又如每一层计划用20对，就用20对的大对数缆分别向各层布放）

<P>可以做接线包，</P>
<P>1、如总线是200对电缆到某层后接一套管分出50对，其余的往上走。</P>
<P>2、每层用一根大对数电缆。</P>

每层楼都应该留有分线孔位置的，就是便于你向两边用户放线。

<P>我看的电信给的图纸,用的100对的大对数,我就比较纳闷!</P>
