Nostalgie: KPN zet inbelplatform uit en laat Xs4all inbelverkeer afhandelen – IT Pro – Nieuws – Tweakers

Posted by jpluimers on 2016/01/17

This Dutch caught my eye: “Dutch telecom operator KPN has turned off the inbound internet dial-up equipment. It keeps possible to dial the number, as dial-up traffic is now handled by provider xs4all”:

KPN heeft de apparatuur van zijn inbelplatform voor internet uitgezet. Het blijft nog wel mogelijk om in te bellen via het nummer 06760-12321, maar het inbelverkeer wordt voortaan afgehandeld door provider Xs4all.

The thread is full of nostalgia on Dial-up Internet access, like:

I still have my original Courier HST Dual Standard modem from USRobotics I got around 1987. It’s looks like the second from the bottom at (image via: Do Modems Still Matter?) the picture below (one day I will make a picture when I’ve cleaned out the glass cabinet it is in; there are some more USRobotics, ZyXEL and DrayTek modems in it too).

There is a very interesting piece of USRobotics (in Russian, but Google Translate does a nice job on it): The history of the US Robotics.

I wrote mentioned the Courier HST Dual Standard before in Going to try PowerLine (next to CAT5, and having used 10Base2, 10Base-T, 100Base-TX and 1000Base-T), but never about the why, so here it is:

The Courier HST standard would train faster and at better speeds over Intercontinental lines than the Trailblazer and Hayes and later V.32bis technologies. In addition, they were also faster with firmware upgrades to support faster speeds than competing brands.

This mattered a lot to me, as initially CompuServe was only accessible by dial-up to the USA. The same for a lot of BBS and FidoNet uplinks.

For me, they weren’t any cheaper buying them (as the BBS discounts for them were not valid in Europe; I bought mine for a more than DM 1000 in Germany) but it was cheaper gaining knowledge (my motto always has been “a life long learning”).

Since the above article,

  • the Sportster magic string entry on Wikipedia vanished, but the info is still at USRobotics Sportster magic string –,
  • I stopped using PowerLine as it wasn’t stable enough, so during the replacement of our solar panels with more modern equipment a few years ago, had CAT-6 pulled up to the utility closed on the bedroom floor.

More info about modem training and standards in this 1998 article:

Everything you wanted to know about modem and fax standards and software, but were afraid to ask is covered in this great overview article by Frank Gao from Gao Research. This article discusses all the functions that go into today’s modem products, but is not tied to any particular hardware implementation.
