ADSL (Asymmetric Digital Subscriber Line) enables faster data transmission over copper telephone lines than conventional modems. It uses frequencies not used for voice calls, allowing voice and data simultaneously. ADSL can transmit up to 4-5 km from the central office but sometimes farther depending on wire quality. At the exchange, a splitter separates the voice and data signals with data routed over the internet.
Broad band theologies are now available all over the word. Because of the technological development is giving more opportunities to improve communication development such as xDSL technologies. Implementation of Digital Subscriber Line technology originally was part of the Integrated Services Digital Network (ISDN) specification and it was published by published in 1984 CCITT and ITU.xDSL represents individual varieties of DSL technology such as ADSL,VDSL,RADSL…. etc.
Digital Subscriber Line is a data communications technology that transmits data faster over the simple copper telephone lines. The signal encoding of xDSL technology is illustrated by a set of modulation techniques. This journal will overview the xDSL technology and will discuss subjects on the efficiency of these modulation techniques.

Stands for "Digital Subscriber Line." DSL is a communications medium used to transfer digital signals over standard telephone lines. Along with cable Internet, DSL is one of the most popular ways ISPs provide broadband Internet access.
When you make a telephone call using a landline, the voice signal is transmitted using low frequencies from 0 Hz to 4 kHz. This range, called the "voiceband," only uses a small part of the frequency range supported by copper phone lines. Therefore, DSL makes use of the higher frequencies to transmit digital signals, in the range of 25 kHz to 1.5 MHz. While these frequencies are higher than the highest audible frequency (20 kHz), then can still cause interference during phone conversations. Therefore, DSL filters or splitters are used to make

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin

Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
