Correct. And IIRC, IDSL was just ISDN with all three channels dedicated to data. Yielding 144kbps at phenomenal distances from the CO.

- Aloha 3y agoIDSL was an ISDN bearer with Frame Relay running on top, it basically didn't use the channelization scheme at all - and IIRC had different framing than a real BRI line.
- marcus0x62 3y agoIDSL used HDLC natively as a frame format. You could run Frame Relay on top of that (or PPP.) Line coding was standard 2B1Q in North America (same as a “regular” ISDN BRI.)
