The world of telecoms is full of acronyms and buzzwords that often don't mean anything to an individual outside of the telecoms industry. So, at DCS Voice & Vision we thought we would take a moment to explain what some of these technical terms mean. Maybe you are about to review your current telephone system and will be talking to some providers about the solutions that they offer. This guide will help you have a better understanding of the terms you will be hearing. 
ADSL 
This stands for 'Asymmetric Digital Subscriber Line'- it is a high speed digital line that allows you access to Broadband. 
 
Auto Attendant 
This is used to guide your caller through the options available to them, eg. Press 1 for sales, 2 for service etc. This enables incoming calls to be handled more efficiently and improves your customers experience. 
 
DDI 
This stands for 'Direct Dial In' - this gives you the ability to have different telephone numbers for individuals within your organisation without needing individual lines. It enables your callers to dial straight into a specific extension without having to speak to the operator. 
 
'Fibre To The Cabinet' is a broadband connection that is delivered using fibre technology. This provides faster download and upload speeds. 
 
This is a telephone system that is hosted in the cloud. It brings you all the functionality of a traditional telephone system, without the need to have costly equipment in your office that requires installing and maintaining. A dedicated portal allows you to add and remove users as required and gives you greater control over how you want your telephone system to work for your business. 
 
IP 
'Internet Protocol' is a way of transmitting information over the internet. 
 
IP Telephony 
Using 'internet protocol', IP telephony delivers your voice calls over the internet. IP telephony has come a long way over the last 10 years or so and it delivers excellent resilience and flexibility. 
 
ISDN 
'Integrated Services Digital Network' enables the transmission of data over a digital line. BT announced a couple of years ago that they would be switching off the ISDN network over the next 10 years, therefore this technology will soon be unavailable and will be replaced by SIP Trunks or Hosted Telephony. 
 
SIP stands for 'Session Initiation Protocol' and is a communications protocol used to set up and clear down sessions with one or more users over the internet. SIP trunks are internet lines whereby part of the broadband connection is dedicated to voice traffic only. These offer a much cheaper and more flexible alternative to ISDN which will be switched off by 2025. 
 
VoIP 
'Voice Over Internet Protocol' is a technology that allows you to transmit voice communications over the internet. This offers great flexibility as you can move and still keep the same numbers and calls on-net are free. 
 
There are lots more acronyms and buzzwords to be heard but the ones we have mentioned above are usually the ones you will come across when talking to a telecoms provider. We hope you will find this helpful..
