ISDN

WHAT IT IS
ISDN (Integrated Services Digital Network) provides high performance, fully digital access to the worldwide telecommunications network – through standard copper telephone lines. This fast, digital transmission service is available virtually everywhere within the TXOL service area. From offices, homes, and remote locations, ISDN lets your employees tap resources and use new business applications where video images and data flow simultaneously along with fax transmissions and phone conversations.

WHAT IT’S FOR
ISDN Basic, also known as ISDN BRI (Basic Rate Interface), supports a wide range of applications and emerging trends by enabling a seamless exchange of information in any medium – voice, data, or video – at high speeds. You’ll have the support you need to use today’s most innovative, fully integrated communications solutions to meet immediate challenges of doing more faster with fewer resources. Using ISDN enables you to benefit from new forces shaping the workplace – including a growing number of tele-workers, dispersed project teams, resource sharing, on-line connectivity, and the need to provide better customer service.

HOW IT WORKS
ISDN sends clear digital signals at high speeds over phone lines. Without a major network investment, ISDN enables your existing phone line to carry voice, data, and video traffic at speeds over four times faster than a conventional analog line, without compression. With compression, speeds can be even faster. Voice calls can be made more quickly and with superior call quality because ISDN is digital. Combining ISDN with TXOL gives your voice system additional power and improves productivity.

HOW YOU BENEFIT
  • Increase productivity using ISDN’s higher speeds – ISDN utilizes two separate 64 Kbps (kilobits per second) channels which can be combined into one 128 Kbps “channel” that’s over four times faster than most analog connections.
  • Faster data transmission speeds can result in shorter connection times and lower usage costs.
  • Avoid the costs and inflexibility of dedicated lines – the same ISDN line can be used to carry both voice and data so there’s no need to wait for a fax to finish before making a call.
  • Take advantage of productivity enhancing applications such as remote LAN (Local Area Network) access, videoconferencing, pre-press graphics, postproduction editing, and digital broadcasting that can reduce travel costs and product development time.
  • Enjoy clear, digital transmission that results in fewer errors and re-transmissions and greater network reliability – all of which save you time and increase productivity.
