Part I. Introduction of TR-069 TR-069 (Technical Report-069) is a communication protocol developed on CWMP (CPE WAN Management Protocol) and the communication link between CPE (Customer Premise Equipment) and ACS (Auto-Configuration Server). With the protocol, CPE can achieve indispensable measures of initialization and operation such as service provision, function setting, the upload and download of files, system detection, etc. Part II. Features of TR-069 Protocol ✔ Automatic configuration of user equipment and dynamic service configuration For ACS, each user’s equipment can mark its model, version, and other info in the protocol. According to

In the past, the campus network always adopts traditional cabling methods. With the development of new technology like AR/VR, 4k/8k videos, WiFi 6, etc., the network traffic shoots up and some problems of the network are exposed. For instance, there is no way to manage the network uniformly because there are lots of devices and fault points. It cost a lot to set up a sole network for each of the multiple systems. In this circumstance, POL is created to solve the problems. Part I. What is Passive Optical LAN

Have you heard about PoE switch? PoE switch is a switch supporting powering via cable, which can not only achieve data transmission like a general switch but also supply power to network terminals. In this article, we will introduce more details about the PoE switch to help you have a better understanding of it. Part I. What is a PoE switch in Ethernet? PoE Switch is a typical Ethernet powering system. When the devices connect to multiple pieces of equipment, PoE switches can simplify the cabling and reduce the network

PoE is called Power over Ethernet. A complete PoE system consists of PSE(Power Sourcing Equipment) and PD(Powered Device). In this article, we will introduce several connection methods of PoE Switch to show you how it connects to terminal devices such as IP cameras. 4 Methods of Connecting PoE Switch to IP Camera (Terminals) 1. Both switch and terminal devices support PoE. In this case, the PoE switch can connect to wireless AP and IP cameras via cable directly. This is the easiest way but you should also notice: ● Make sure the PoE

1. Basic Introduction of V-SOL Layer 2 PoE/UnPoe switch Recently, V-SOL has just launched three series of Layer 2 switches, including the PoE switch and the UnPoE switch. There are 100M switch and Gigabit switch. The PoE switches only support standard PoE of 48V, AF(15W)/AT(30W). All switches support the following features.   ● Shift into three modes with one button● Support VLAN● QoS priority● Thunderproof and static-free protection● Working temperature: -10℃~+50℃● indicator lights of working status, helping analyze faults● Link extension Now let’s get to learn three series of switches one by one!  ● V10XX Layer 2 PoE Ethernet Switch  ● V11XX Layer 2

In the past, plenty of large and medium enterprises spent a lot on IDD call charges. Although they save the cost by using IP phone cards and other ways, it’s difficult to re-dial due to the complicated procedure and the high local call charging. Thus, VoIP Gateway is created to solve the high IDD call charges. This post will introduce what a VoIP gateway is. Part I. What is a VoIP Gateway? VoIP is a device that transfers call traffic into data packets and transmits them via the Internet. In

Does the Internet speed limit your need for extremely fast downloads and uploads? Are you unable to enjoy Gigabit network even after you have upgraded to Gigabit broadband? Don’t worry! FTTR provides a networking solution that covers the whole house with high speed and stability. Since then, you can access stable Gigabit Internet at every corner of the home and watch 8K videos in the future. 1. What is FTTR? FTTR (Fiber to The Room) refers to replacing network cables with optical fibers, laying optical fibers in each room. It achieves interconnecting with home

The analog phone system or POT (Plain Old Telephone Service) is the service provided by the telecom company. The telecom company connects the phones with twisted pair wires. To increase the distance of signal transmission and management, there are also many communication network devices, such as PBX, VoIP gateway, and routers. Switching to a VoIP phone system has become a popular choice for many small and medium businesses due to better connectivity, expanded calling features and tools, and the possibility to make and receive local and international calls. Before VoIP,

V-SOL CPE XMC1841 is a 4G smart CPE with four 4dBi high gain external antennas, which provide solid wireless signals and fast speed. Without exaggeration, the CPE has passed a series of powerful tests. Part of the tests is shown in the images below. Now let’s review the test in terms of three aspects including hardware design, system solution, and reliability test to see what CPE performs excellently.  1. Hardware design of LTE CPE XMC1841 The shell adopts double-color Injection mold with high-quality original maternal. In order to promise quality, a series

1. Importance of Fiber Optic Network Security Network security has a growing impact on organizations with large data transfers. Digitalization, increasing family networks, and Cloud storage mean that network security should be attached to great importance. Without a secure network, financial and personal data can be vulnerable to malicious hacking and destruction. Departments of education, finance, government and health would be frequently targeted. Although many companies use encryption technologies to prevent data at rest from attack, the data is still easy to be intruded and intercepted in transferring. It’s said
