For those in the know… this was bad ass home internet in 1997.
[ Sort of the Laserdisc of Internet and Telephony technology ].

At the time I actually had two ISDN lines, each that supported two B-channels. With a little bit of trickery I could connected into our Lucent PRI digital bank and bond all 4 B channels together for 256K up and down.

As a bonus, you could do cool stuff with forged Q.931 headers, as Tony Jones can attest to.
