Web Jargon Explained by TalkTalk Expert

Tuesday, August 18th 2009

TalkTalk UK ISP's product development head, Paul O'Sullivan outlined in an article prepared for the TalkTalk official blog, a few of the confusing abbreviations, phrases and words related to the broadband sector. He also attempted to clarify these jargons for the convenience of the broadband customers in the UK, citing the fact that many of those were easily explainable.


O'Sullivan explains the term DSL(digital subscriber line), in the the official TalkTalk blog as an internet service network that depends on the conventional copper telephone wires. The term DSLAM that stands for the digital subscriber line access multiplexer, refers to a device which combines the transmitted signals to be carried on a fast backbone.


The blog clarifies the term NGA as next generation access, a phrase which covers the entire ADSL and ADSL2+ broadband services. The ADSL and ADSL2+ technologies effectuate high broadband speeds of up to 24Mbps. FTTC has been described in the blog as fibre-to-the-cabinet, which is an advanced broadband technology represented by a fibre optic system. The blog also claims that this system is being trialled currently by TalkTalk.


Fibre-to-the-premises, widely known as FTTP is very much identical to the FTTC system, although the former, with connection speeds of up to 100Mbps achievable, is designed for office and home users. Interestingly, O'Sullivan has played it down refering to it as a service expensive to implement. He adds that the FTTP is not expected to play a significant role in the future online network of the UK, due to this reason.


He explained Mbps as the expression used to represent the bandwidth measurement called megabits per second or millions of bits. The jargon 21CN was expanded by the blog as 21st century network. O'Sullivan who joined TalkTalk in 2008 November, concluded stating that its network was the biggest comprehensively IP-enabled UK network.
