Comment ISDN: It Still Does Nothing (Score 1) 92

It still amazes me that, as late as the 1990's, and well after 56kbit modems were prolific, ISDN was being offered up by the ILECs as "broadband," at metered rates that made Ma Bell's long distance charges look like spare change.
Happily, it wasn't too long before ISDN was put out of everyone's misery when DSL showed up. And now, finally, after fifty years of pissing about, fiber is finally being pulled to the premises.
If you really need ongoing ISDN support, you can pull the source code from an old Git commit and update it. But I feel quite comfortable in opining: ISDN support will not be missed.
