David, According to TBR 21 clause 4.2, you must use an RJ-11. TBR 21 applies to "non-voice" PSTN equipment.

I've seen this done, and they do fit OK as long as you're careful when you install the plug. As far as I know, the FCC and IC are only concerned with the connector you intend to connect to (the one on the wall), so it shouldn't be a registration/certification problem in North America. The EU and other countries may be a problem, though. --jack marshall > -----Original Message----- > From: David Gelfand [mailto:[email protected]] > Sent: Tuesday, December 14, 1999 12:16 PM > To: [email protected] > Subject: RJ-11 plug into RJ-45 jack? > > > Hello listmembers, > > Here is an interesting question put to me by our design > engineers.
