Today, public schools in Washington connect through the state K-20 network at speeds much higher than this. Private schools also connect through various ISPs at much higher rates.
Since US West has altered their rates to provide an affordable ISDN flat rate charge, we have been using dedicated ISDN BRI connections to schools in the greater Seattle area in order to allow them access to the internet and our server. We have chosen to use ISDN BRI for several reasons:
There are three main reasons for using BRI over PRI
We currently Digi International retoura ISDN router on both sides. This allows each school to dial up and establish a PPP connection through us using a predetermined line and address range (we like to know who is where). We are routing to subnetted class C's at the schools. So far the routers we have for testing are from Combinet, Ascend and Digi. The Digi comes in a single and dual BRI styles. We use the dula model at our central site with the single version at the schools.
