U.S. Switched Access and ISDN Lines
If there are any old ISDN hands out there like myself you might like to see the charts I just published on my own website http://www.larribeau.com. They show that U.S. BRI and PRI lines seem to have stabilized over the last couple of years. BRI are declining slightly and PRI are now growing slightly. There was a big drop in 2002 through 2004, probably due the conversion of dialup to broadband, but since 2005, the number of PRI has grown.
