Articles
Below you'll find telecoms articles, tutorials and howto pieces on all aspects of next generation telecoms, including telecoms network technology, telecoms OSS and BSS, how the telecommunications industry is changing, telecoms regulation in the UK, the EU and worldwide, and security and assurance for telecoms networks and services.
The articles are created and maintained by our expert telecoms training instructors and consultants, and we hope you find them useful tutorials for learning the basics of a telecoms topic; they can be bookmarked on any of the popular social networking sites if you'd like to come back to a particular article later, or recommend it to others. We also supply an RSS feed (at the bottom of the left sidebar) if you'd like to be notified of new articles as they appear.

VoIP is vulnerable to poor quality through mechanisms that did not affect traditional circuit-switched, PSTN telephony.
