A. W. Communication Systems Ltd — 1 prefix (MA-L)

A. W. Communication Systems Ltd holds a single confirmed MA-L OUI-24 block, 00:15:6E, registered to a Carlisle, Cumbria address in the north of England. Unlike a bare shell registration, the company is traceable to a real UK limited company — Companies House number 04891652, incorporated in September 2003 — that traded publicly as AWCSL out of the same Carlisle locale and built ISO 9001-certified radio-control hardware for the professional mobile radio (PMR) / critical-communications industry: desktop base-station controllers (the DRC-1/DRC-1s and DRC-U line), a Linux-based IP-capable controller (DRC-ip), a multi-operator IP packet switch (TRICX), a rack-mount matrix switch (DS32), and a remote control unit (TC1). The Ethernet/IP-capable DRC-ip and TRICX products are the plausible carriers of this OUI. The company's story ends in liquidation, not obsolescence-by-neglect: it entered creditors' voluntary liquidation in July 2018 and was formally dissolved in November 2021, so it is now defunct. Only one OUI block was found for this org across all three IEEE registry classes, and IEEE publishes no assignment date for it, so none is recorded. No CVEs or security advisories turned up for any AWCSL product.
