Drivers for Planet ISDN 2B R461C?
Posted by: greystash on 2020-07-18 13:46:25 Does anyone have the drivers for this card? It's unrecognized by my system and I can't find the drivers anywhere 🙁
Posted by: NJRoadfan on 2020-07-19 03:22:13 Do you have a BRI ISDN line to hook it up to? Phone companies in the US have long since stopped offering the service to new customers. Might not be worth the hassle.
Posted by: greystash on 2020-07-19 06:57:33 No I don’t all that is long gone here in NZ, but the card has an Ethernet port so I thought I might be able to use it as an Ethernet device? Would this make sense?
Posted by: cheesestraws on 2020-07-19 07:19:21 the card has an Ethernet port Just because it's RJ-45 doesn't mean it's Ethernet! ISDN, confusingly, can also use RJ-45 jacks and transmit over CAT5/whatever cable, but the pinouts and signalling are quite, quite different.
Posted by: Cory5412 on 2020-07-19 07:21:44 Mirroring that, there's a very good chance that that's a serial console port or a voice channel output port or something similar to that. ISDN and Ethernet were both expensive enough whenever that card was new that a combination ISDN-Ethernet card seems moderately unlikely as a product.
Posted by: greystash on 2020-07-19 07:23:23 Ah bugger that’s a shame. Thanks for the info! Looks like I’ll have to get one of the Asante AAUI adaptors instead.
Posted by: NJRoadfan on 2020-07-19 07:23:24 Its likely a RJ-14 port. BRI ISDN was either 2-wire (U interface, common in USA) or 4-wire (S/T interface, common elsewhere, requires NT1).

For distribution, I believe RJ-45 was also used, with the extra 4 pins being used for power, or something similar.
