Editing Packet switching (section)

====Datanet 1====
Datanet 1 was the public switched data network operated by the Dutch PTT Telecom (now known as [[KPN]]). Strictly speaking Datanet 1 only referred to the network and the connected users via [[leased line]]s (using the [[X.121]] DNIC 2041), the name also referred to the public [[Packet Assembler/Disassembler|PAD]] service ''Telepad'' (using the DNIC 2049). And because the main [[Videotex]] service used the network and modified PAD devices as infrastructure the name Datanet 1 was used for these services as well.<ref name="dn1descr">{{cite web|first=H.J.|last=Steneker|url=http://alexandria.tue.nl/extra1/afstversl/E/354398.pdf |archive-url=https://ghostarchive.org/archive/20221010/http://alexandria.tue.nl/extra1/afstversl/E/354398.pdf |archive-date=2022-10-10 |url-status=live|title=Graduation Report on X.25 data services in GSM network|website=Electrical Engineering - [[Eindhoven University of Technology|TUE]]|date=16 May 1991|page=20|access-date=15 June 2011}}</ref>
