ISDN

Plain ISDN, a type of Integrated Service Digital Network system is the first step up from an analog line, but has since been superceded by ISDN30. We offer a comprehensive set of ISDN-based phone systems. The choice between using the plain old telephone service (POTS) and ISDN does not just come down to economics. By using ISDN you will be able to introduce new features into your company's telephone system and make use of additional applications, which will enable your business to grow and take up any innovative opportunities offered by your customers and suppliers. Your company will take a further step from the analogue to the digital age.

  • connect to the Internet for sending email and browsing the Web
  • use dataconferencing and videoconferencing over the Internet or point-to-point
  • transfer files over the Internet or point-to-point
  • potentially, use the Internet for your standard telephone calls (voice over IP or IP telephony)
  • connect to your network from outside the office (remote access service or RAS)
  • synchronise your telephone and computer systems (computer telephony integration or CTI)
  • introduce advanced features such as Direct Dialing In (DDI), Multiple Subscriber Numbering (MSN) and Interactive Voice Response (IVR)

A digital ISDN channel has the same voice telephony usability as an analogue POTS line, but can carry data more quickly and with fewer errors. Data calls are therefore shorter, and the usability of applications is improved. For example, a shared network connection to the Internet will be far more useable with ISDN, as additional channels can be combined giving access to more bandwidth. Each ISDN channel carries similar charges for rental and calls as a POTS business line, although charges for ISDN channels may include built-in call allowances and discounts for long term commitment, making the relative costs of ISDN seem more. The equipment required on the company's premises to operate an ISDN service, such as the PBX, tends to be slightly more expensive for ISDN than for an analogue system but with more functionality.

A POTS line can be converted to a Basic Rate ISDN (BRI) line with two channels, or a new wire can be installed by Telefonix Voice & Data. To use a stand-alone computer for ISDN you need an internal ISDN card or an external terminal adapter. For a local area network (LAN), you need a router and/or an ISDN PBX or similar device. For computer telephony applications, an ISDN PBX with a computer interface is essential. As many ISDN applications have been designed for BRI, a Primary Rate ISDN (PRI) service may need a multiplexer device at the PBX in order to convert some of the channel interfaces to BRI.
