More on ISDN30e business lines

ISDN stands for Integrated Services Digital Network, and the ‘e’ on the end denotes the European standard ISDN service rather than the older DASII variant that was a UK standard. ISDN has been available in the UK since 1992.

 

ISDN30e is ideal for customers requiring any number of lines from 8 upwards. It connects between 8 and 30 lines/users on a single bearer cable, and the ability to use multiple bearers means it is the most flexible digital business phone line service available for a growing, thriving business.

 

Like ISDN2e, ISDN30e uses Direct Dial In (DDI) numbers, allowing individual numbers to be used for individuals, departments and marketing purposes.

Key features include:

  • 8 channels + on one connection
  • Good value DDI numbers available in blocks of 10
  • Can port an existing single number as an SNDDI (Single Number DDI)
  • Up to 5 DDI ranges (an SNDDI counts as a range)
  • Six-hour fault clearance SLA
  • Increase or decrease channels very easily, in single channel increments
