AccessLan Communications, Inc. — 00:10:33 (MA-L)

The OUI 00:10:33 is registered to "ACCESSLAN COMMUNICATIONS, INC." at 44 Airport Parkway, San Jose, CA 95110, US — a single MA-L block, but one that traces to a real, well-documented telecom-equipment company rather than a bare registration. AccessLan was a venture-backed San Jose startup (founded 1997, roughly $97.6M raised from investors including Sequoia Capital and Accel) that built carrier-class DSL/ATM access equipment for Local Exchange Carriers and independent operators. Its named products were the PacketLoop PL-1000 and PL-2000 IP-DSLAMs (marketed as "i-SLAMs"), used for Voice-over-DSL, Internet access, Frame Relay, VPN, and application-hosting services — the PL-2000 central-office shelf carried up to 240 DSL lines (960 per 7-ft bay). Advanced Fibre Communications (AFC) acquired AccessLan on March 27, 2002 (~$43M cash plus assumed liabilities and AFC shares) to fold its ATM-to-IP migration technology into AFC's Telliant 5000 platform; AFC was itself later acquired by Tellabs. The equipment is legacy, discontinued carrier infrastructure from the late-1990s/early-2000s era, so the 00:10:33 prefix would appear in carrier DSL access hardware of that period rather than any consumer gear. No CVEs, advisories, or abuse reports are associated with the OUI, and there is no evidence of devices carrying it in active internet-facing deployment today.

Analyst note

a single-OUI registrant, but a substantive, corroborated one (named products, funding history, dated M&A event). The 00:10:33 prefix reliably identifies genuine late-1990s/early-2000s AccessLan carrier DSL access equipment; given the company's 2002 acquisition and the gear's age, such devices are very unlikely to appear in modern networks.
