A2B Electronics AB — 00:22:80 (MA-L)

A2B Electronics AB holds a single MA-L block, 00:22:80, registered to the company at Box 14, Motala, SE S-591 21, Sweden. Unlike a bare single-OUI shell, this registrant is an identifiable operating manufacturer with a documented product line and corporate history. Founded in 1997 by Bo Lindqvist and based in Motala, Sweden, A2B built professional cable-TV and SMATV headend equipment — COFDM-to-QAM transmodulators, terrestrial-to-cable distribution units (the Multibox / MyM series), and later a software-configurable "Chameleon" headend platform. Germany's WISI (Wilhelm Sihn Jr. GmbH & Co. KG) acquired the company in June 2009; it continued as a subsidiary and was formally renamed WISI Norden AB in 2012, and it remains an active WISI Group entity today. Because this is professional broadcast-industry hardware rather than consumer network gear, its MACs appear on operator-side distribution equipment, not end-user devices. Only one OUI block was found for this registrant across the IEEE MA-L, MA-M, and MA-S snapshots — no evidence of multiple assignments — but the independent, multi-source device and corporate corroboration establishes it as a real manufacturer. The usual OUI caveat applies for asset classification: a globally-administered 00:22:80 address reliably identifies A2B/WISI Norden hardware, but IEEE publishes no registration date for the block, so any "date registered" surfaced by third-party lookup tools is a database artifact, not an IEEE fact.

IEEE assignment

00:22:80 → A2B Electronics AB, Box 14, Motala, SE S-591 21, Sweden [Confirmed] — IEEE MA-L (cross-checked Wireshark the Wireshark manufacturer database DB)

Registry / block size

MA-L (24-bit OUI, /24 large block) [Confirmed] — IEEE MA-L

HQ / country

Box 14, Motala, SE S-591 21, Sweden [Confirmed] — IEEE MA-L (registry address)

Company status

active as WISI Norden AB (WISI Group subsidiary) [Confirmed] — wisigroup.com/our-company/our-history, wisi.se/about/wisi-norden-ab

Founded

1997, by Bo Lindqvist, Motala, Sweden [Likely] — evertiq.com/news/14434 (single trade-press source for founding year/founder)

Corporate history

acquired by WISI (Wilhelm Sihn Jr. GmbH & Co. KG) June 2009; renamed WISI Norden AB in 2012 [Confirmed] — broadbandtvnews.com (2009-06-16), wisigroup.com history page

Device types

CATV/SMATV headend equipment — COFDM/DVB-T-to-QAM transmodulators, terrestrial-to-cable distribution units (Multibox / MyM series), software-configurable "Chameleon" headend platform [Confirmed] — evertiq.com/news/14434, wisigroup.com Active A2B Products page

Usage context

professional/broadcast-industry equipment for network operators (Scandinavian/Northern European cable-TV market), not consumer network gear [Confirmed] — evertiq.com/news/14434, wisigroup.com

Registration date

Unknown — IEEE publishes NO assignment/registration date for OUI blocks; the cleancss.com lookup for 00-22-80 displays no date field either, so nothing to record [Confirmed as absent] — standards-oui.ieee.org/oui/oui.csv columns, cleancss.com/mac-lookup/00-22-80

Multi-OUI check

only one block (00:22:80) found; no MA-M or MA-S entry for this registrant [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry

Security context

Unknown / no findings — no CVEs, advisories, or abuse material found for A2B devices or the 00:22:80 prefix; professional broadcast gear has low public security-research visibility, so read this as "not found," not "confirmed clean" [Unknown] — no source

Analyst note

a globally-administered 00:22:80 address identifies genuine A2B/WISI Norden headend hardware; the block is single-vendor and unambiguous, but do not expect it on consumer endpoints — it belongs to operator-side CATV distribution equipment.
