Ten Mistakes and Five Cautions for Comprehensive Network Cabling
Browse: Release Date: 2019-11-05
Today, in modern society, whether in the home or in the office, the use of the Internet is essential. So, what are the common mistakes we make when we make comprehensive wiring? At the same time, what should be paid attention to? In this regard, the editor specially collected some information. Let ’s take a look!


Ten errors in network cabling:


I. No forward-looking planning for the overall network
Second, voice and data services use different lines
Third, the line is not effectively managed
Fourth, the network cable and cable are laid in parallel
Five, the network cable is in the same area as the "interfering" equipment
Six, regardless of the actual distance restrictions
Violation of the requirements of laws and regulations
Eight, neglect to test the line
Nine, do not follow industry standards
X. No rational planning for new lines


Five categories of attention:


1. Is your network cabling qualified?
The level of internal network cabling is very important. Because network voice requires additional bandwidth to improve voice quality, it is recommended to use a CAT-5e (100M) or CAT-6 (1G) network cable to obtain the best voice quality.
According to experience, most of the problems of many VoIP systems are caused by the use of wrong specifications of network cables or the use of poor quality network cables. In particular, some domestic enterprises did not hire a regular construction contractor when wiring. These road construction teams cut corners and used a variety of inferior network cables, causing enterprises to suffer losses.
2.Current Internet bandwidth specifications of enterprises
Generally, the Internet network bandwidth of small and medium-sized enterprises is not too high. Before using VoIP, you may need to consider upgrading the Internet bandwidth first. If more than 10 people in the enterprise use VoIP, we recommend that at least one 1M fiber-optic dedicated line or a higher specification Internet line be dedicated for use.
3.The router can be optimized for voice and fully support QoS and virtual local area network
This question is raised to address the current chaotic management of domestic enterprise LANs, if the corporate network itself is very unstable. P2P or intranet attacks and viruses have prevented the entire corporate network from accessing the Internet properly. How can VoIP voice work properly?
The answer is that you need to upgrade your existing router. Enterprise deployment of VoIP also needs to assess how QoS is defined and transmitted in your network architecture. The quality of VoIP voice can be directly affected by network delay and packet delay. Unstable lines may even cause VoIP voice disconnection.
4. Need a set of independent voice wiring architecture
Although VoIP runs on an IP network, it does not mean that you can merge it with your existing network.
The CTO should consider how many existing lines need to be replaced, how many internal voice call users need to be supported, and estimate the difficulty of supporting the construction of the wiring of these IP phones. Finally, consider whether an independent wiring system dedicated to VoIP should be constructed.
There is also another consideration regarding cabling. Companies should also evaluate whether to deploy a Power over Ethernet (PoE) system to power new VoIP phones. Of course, you can also plug their power plugs into AC wall sockets, but this may be a little unreliable. In the event of a power outage, the company's external calls will be interrupted.
5. How to deal with the existing traditional telephones?
In foreign countries, some of the existing phone numbers can be converted to the new VoIP system, but not all of them. As for domestic regulations, it is currently not feasible due to the restrictions of policies and regulations.
Enterprises need to consider a set of planning measures after considering the above 5 points in order to reduce the obstacles in the construction process.
