Telecommunication network refers to the construction and management of the former Ministry of Telecommunications network, such as the traditional telephone exchange network (PSTN), digital data Network (DDN), Frame Relay Network (FR), ATM network. In the PSTN network, some of the main communications backbone has been achieved optical fiber, while the user network is mostly copper wire, Generally used only

FTTH suppliers. Three, the Beacon communication FTTH Solution 1. Overall solution As the mainstream supplier of network equipment in domestic telecommunication industry, Beacon Communication has a deep understanding of the demand of operators and the characteristics of telecom networks. Research and development of telecom-grade gepon products not only meet the latest IEEE802.3AH standards, but also can be compatible with the existing PSTN network

Softswitch technology is an important part of the knowledge that we have to learn in Switch Applications. Have you ever heard of the H.323 protocol in the Softswitch technology? This Protocol plays an important role. Next we will introduce the Softswitch technology in detail. There are two strategies in the network architecture of the Next Generation Network: Smart endpoints and edges, simple network facilities, and simple endpoints and edges, SMART network facilities. For the former, because th

integrated access network device should be able to smoothly evolve to NGN network and meet the development trend of the network. 4. Protection of existing investment capabilities-PSTN remains the foundation of fixed network operators, and traditional voice remains the main business revenue source of telecom operators. Facing the huge PSTN network resources, it is also important for fixed network operators

As a standard for wireless broadband MAN, WiMAX technology has great advantages over the previous 3.5GHzMMDS in terms of non-line-of-sight transmission and spectrum utilization efficiency. As one of the core of the Next Generation Network, the Softswitch Technology Based on the IP network is very mature in terms of comprehensive service access and QoS level assurance, and will replace the existing PSTN devices. This article describes the performance t

management system, and terminal devices. The gateway is located at the interface between the Public Telephone Network (PSTN/ISDN/GSM) and the IP network to complete the bridge task between the public telephone network and the IP network. Main functions include: telephone/fax signaling, media stream, management information, and synchronous signal conversion between networks on both sides; call Establishment and release on the

completed. In addition, it must also be able to convert some basic call signals processed by the original user board, such as detaching, dialing, and hanging up) into the protocols that can be transmitted on the network, in this way, the interaction between the access device and the softswitch is realized. In this way, Softswitch can receive and process the information sent from the access device, control the access device, and establish a call connection.Packet transmission network: in NGN, pa

The use of routers and switches is indispensable in network construction. In some vswitches, we use them in combination with the H.323 protocol. Today, we will introduce you to the basic knowledge of Softswitch technology and H.323 protocol. There are two strategies in the network architecture of the Next Generation Network: Smart endpoints and edges, simple network facilities; simple endpoints and edges; SMART network facilities. For the former, because the driving force of end-to-end multimedi

I. Applicable conditions: 1. DDN is the main line, and PSTN is the standby line. 2. The HDLC protocol is used on DDN and the PPP protocol is used on PSTN. 3. dynamic routing can be performed on the main line or the standby line. In this example, dynamic routing is performed on the main line. II, Network Topology: Iii. Solution description: HDLC support is one of the most impor

Thanks to the above advantages of ATM technology, it has been widely valued by Telecom and computer networ

telephone exchange technology, intelligent network technology, Internet technology, and broadband access technology to take advantage of the resource advantages of traditional operators, provide users with rich and high-quality new services. Considering that the NGN technology is not yet mature and is still evolving, the basic guiding ideology of Beijing Communication is: comprehensive follow-up research, active participation in standard formulation, and timely commercial experiments. At presen

PSTN network bandwidth utilization and reduces transmission costs. The operator expects VoIP to significantly reduce the cost of long-distance speech. In fact, there is a big gap between VoIP network operations and the original ideas. The VoIP networks of most carriers in China are hosted on private networks, that is, IP infrastructure networks specially built for VoIP. The reason is simple. Only in this way can we ensure service quality and system s

Control Protocol (BICC). The signaling interconnection of the server and the external traditional network uses signaling gateways (SGW) to achieve interconnection and interoperability. Among them, T-SGW realizes the interconnection and interworking with the public Switched Telephone Network (PSTN) network, R-SWG realizes the interconnection and interworking with 2G mobile network.The R4 network structure is directly evolved from R99, and some network

Rich presence technology surpasses the simple "Green Dot" state, simple statuses only list basic statuses such as "do not disturb", "meeting", "exit", and "offline. Rich statuses are algorithms used to determine the user status based on activity, and sometimes the status is displayed across multiple devices. ● Audio and video conferencing.
