Vectoring helps Irish Telecom compete in the broadband market

adopt FTTC to quickly build UWB network, and fully enable vectoring to achieve 100 megabytes to the home, making Irish Telecom's UWB network rate in the leading position in Europe

Telecom Ireland is the largest integrated telecommunications operator in the Republic of Ireland, with a nationwide copper network infrastructure. However, Ireland Telecom's traditional DSLAM network using ADSL technology has been at a disadvantage in the broadband market competition, and has been double attacked by cable operator UPC and class II telecom operators such as BT Ireland and smart Telecom. In particular, cable operator UPC's 100m broadband products based on docsis3.0 have attracted a large number of users, resulting in a large loss of broadband users of Ireland Telecom, and the broadband market share has fallen from the initial 70% to 50%, And revenue per user (ARPU) is also declining. In the face of fierce market competition, Irish Telecom must build FTTx UWB network and comprehensively speed up its broadband products in order to enhance its competitiveness and revitalize its market position as a major operator

fttc and vectoring speed up outside the full warranty period

inspired by the success of the neighboring British Telecom (BT) Nga project under this layout (next generation ultra wideband access), telecom Ireland decided to invest 100million euros to build the NGA network, mainly FTTC, and deploy FTTH in appropriate areas. Through bidding and competitive testing, Irish Telecom finally chose the FTTC solution of Huawei, the main supplier of BT NGA, and adopted the same outdoor cabinet as BT, which greatly accelerated the construction speed of Nga network

in July 2012, Ireland Telecom started the construction of Nga network project, choosing the mode of phased investment and on-demand deployment. First, it completed the speed-up of VDSL2 network based on FTTC, and verified the speed-up effect of vectoring in a small range. After more than a year of deployment and trial operation, in the second half of 2013, Ireland Telecom began to start the full FTTC vectoring enabling speed-up, and the average access bandwidth of users increased by about 50% on the basis of VDSL2, It has greatly enhanced the competitiveness of Irish Telecom broadband products. Huawei helped Irish Telecom to carry out the planning and implementation of full vectoring enabling. In addition to providing vectoring centralized processing engine and corresponding upgrading services, it also provided imanager n2510 line support system to realize the pre evaluation of vectoring line bandwidth, line test management, line performance optimization and terminal capacity evaluation, so as to improve the operation and maintenance efficiency while increasing the network speed, and reduce the possible risks and transformation costs in the speed increase

Irish Telecom is the first telecom operator to deploy vectoring technology on a large scale in the world. As of May 2014, it has successfully deployed more than 4000 FTTC outdoor cabinets with little but constant demand between magnets and the operation of self-supporting static load systems, and fully enabled vectoring, providing 70m to 100m UWB access to more than 700000 household and enterprise users in Ireland. Carolan Lennon, the company's network director, pointed out that by 2020, the download speed required by European home and small business users will reach 100m, and the vectoring technology enables us to meet the future bandwidth needs of users on the copper based broadband network now. By 2016, we plan to provide broadband services to 1.4 million home and enterprise users. Once Nga project is completed, Irish Telecom will surpass most European fixed access operators in broadband access rate. We will maintain close cooperation with Huawei and other world leading suppliers to further explore the latest technologies in the access field such as St

NLV and St speed up in dense cities

nlv (node level vectoring) technology can realize crosstalk cancellation for all users between two devices. It can be used not only in FTTC sites, but also in urban central computer rooms with high-capacity equipment requirements

in several large cities in Ireland, such as Dublin, due to the dense houses and narrow streets, it is not suitable to place outdoor cabinets, and many users' copper wires are directly connected to the exchange room without a transfer box in the middle. The average distance between these users' copper wires is less than 500 meters, which is suitable for the use of vectoring technology. However, due to the large number of users coming out of the exchange room, the single frame 384 line vectoring system cannot meet its capacity requirements, At this time, we need to consider using NLV technology to realize 768 line high-capacity vectoring system. For the machine room with a large number of individual users and a capacity of more than 768 lines, multiple devices are needed. The way of wiring can be used to connect the users of the same cable with mutual crosstalk to the same device, and the users of different devices are not in the same cable, so as to ensure that vector can really play a role. At present, the NLV scheme in dense cities is under initial testing

in addition, for the high-end users in the city who need higher bandwidth, Quan should also consider whether the oil is too thin and dirty. If FTTH Optical fiber is used to enter the home, an appointment should be made, and the home optical fiber wiring should be carried out. The engineering is complex and the cycle is long, which will also affect the home decoration. Therefore, Irish Telecom is considering reusing copper wire resources and using ST technology to provide ultra-high rate access. It plans to deploy st equipment in the underground manhole on the street, connect it to the user's home through the existing copper wire, and use the user's reverse power supply to solve the problem of equipment power supply. At present, Ireland Telecom has completed the laboratory test of St in cooperation with Huawei, and is preparing for the st commercial test Bureau

develop national broadband and achieve remote coverage

the development of national broadband in Ireland is uneven. Urban users can enjoy UWB services, but there are still many difficulties for users in remote areas. The Irish government actively caters to the digital EU broadband plan and promises to provide a bandwidth of no less than 30mbps no matter how remote and difficult it is. The latest project budget is 1billion euros, which is expected to cover 600000 to 900000 users in remote areas

the Ministry of communications of Ireland started the NBP (National Broadband Plan) project in August 2012. As the largest telecom operator, Irish Telecom is duty bound in the construction of national broadband. At present, it has begun to carry out type selection tests with Huawei for UWB network solutions in remote areas, including fttrn (fiber to the remote node), top box scheme for active transformation of passive cabinets, And equipment remote supply scheme, etc

Irish Telecom adopts FTTC to quickly build ultra wideband network, and realizes 100 megabytes to the home through fully enabled vectoring, which makes its ultra wideband network rate in the leading position in Europe, and also sets a big t model for the scale deployment of global vectoring. Its good return on investment and ultra-high access speed will also promote more operators to build ultra wideband network using copper wire innovative technology

voice of customers

vectoring technology enables us to meet the future bandwidth needs of users on the broadband network based on copper wire. By 2016, we plan to provide broadband services to 1.4 million home and enterprise users. We will maintain close cooperation with Huawei and other world leading suppliers to further explore the latest technologies in the access field such as St
