Yes, you can get BRI modem racks and hang them off a PM2 but you lose a ton
of features. A better solution that a number of people are using is to get
an Atlas 800 which will convert BRI lines to PRI and use a PM3. Basically
you plug a bunch of BRIs into the 800 and get PRI out the other side. A
user ( jp@midcoast.com ) on the portmaster-users list posted a url to show
an example of doing this:
