电话线、网络线、有线电视线及音响线称之为弱电线。随着家庭生活的智能化，弱电线路的预设不容忽视。家庭装修中，电话线、网络线、有线电视线的布设需注意以下几点：
1.避开强电线：弱电信号属低压电信号，抗干扰性能较差，所以弱电线地走线应该避开强电线（电源线）。国家标准规定，电源线及插座与电视线及插座的水平间距不应小于50厘米。
2.注意防潮：插座下边线以距地面30厘米左右为宜。一般来说，这些弱电线常常在房顶或地板下布线，所以为了防潮和更换方便，这些线的外面都要加上牢固的套管，并在加上套管前检查线是否有断路或短路。
3.预留足够插孔：考虑到家庭生活的发展和需要，一般客厅、每个卧室都要预留埋设电话线、网络线、有线电视线插孔各1~2个，并且要分布在不同墙面，以便于电器摆设位置的变化。卫生间、厨房也可根据需要考虑是否预留一个电话插孔，餐厅也可考虑是否预留一个预先电视线插孔，以备就餐时看电视用。
4.集中控制：随着网络和信息时代的到来，一个家庭安装两部电话或多机上网，以是很平常的事。为保证线的对接质量，且方便维修，好为家中的电话线和网络线设计一个集中控制单元。可以根据网络线进室的位置选择门厅、过道、书房上方等某个地方，设计一个小线盒（形状如电源分线盒），将所有外部进户的电话线、网络线、有线电视线线到达这个线盒，同时家中每个房间的电话插孔、网络插孔、有线电视插孔的线也到达这个线盒，可以根据家庭需要在线盒内进行连线。为保证信号质量需要在线盒内加一个电视信号多路分支适配器，如果家中多台计算机上网，还需备一个网络集线器。
