Default Re: Finding old ISDN PRI terminals?

The only PRI terminal I've ever encountered was a card in a Cisco router, used to support multiple simultaneous dial-up internet connections. It was useful because it supported V.110 rate adaption, which enabled fully-digital connections from GSM mobile phones. I remember very well that from pressing "connect" on the phone to having a fully configured, working mobile internet connection (albeit at 9600 baud) took 6 seconds. Pretty impressive, even today.

Otherwise PRI connections tended to go to the telephone exchange in the building, not to individual phones.
