Telco Systems, Inc. — 6 prefixes (MA-L)
Summary
- // what this is
- Telco Systems is registered to MAC prefix
00:00:1Fand 5 more in the IEEE OUI database. When a device's MAC address begins with00:00:1F, that block was registered by Telco Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Six independently-registered MA-L blocks under one identical org/address, plus a live commercial product catalog and corporate acquisition history, together establish company substance beyond a bare single-OUI registration.
About this vendor.
A MAC address beginning with one of six OUI prefixes — 00:00:1F, 00:0F:96, 00:10:CA, 00:40:9F, 00:A0:12, or 00:C0:AB — belongs to Telco Systems, Inc., a carrier-telecom equipment manufacturer. These addresses typically show up on carrier Ethernet switches or telecom-chassis blades, not consumer or home-network hardware.
Telco Systems is a real, long-running vendor: founded 1972, headquartered at 15 Berkshire Road, Mansfield, MA, and acquired by BATM Advanced Communications in April 2000 for roughly $260.8M cash and stock. It now operates as "BATM Networks" with a live product catalog at telco.com.
The six MA-L blocks all register to the identical organization name and Mansfield address in the cached IEEE registry — multiple independent block assignments to one entity is itself a corroborating signal of substance, distinguishing this vendor from a bare single-OUI registrant.
Current products drawing from these blocks include Carrier Ethernet demarcation and aggregation switches (X-Series, E-Series, T-Series) and AdvancedTCA switching blades used in telecom chassis and mobile-backhaul gear. No vendor-specific CVEs or security advisories were found in this research pass; that field is reported Unknown rather than guessed.

- Lookalike orgs not to confuse
- MA-L 54:7F:A8 "TELCO systems, s.r.o." (Slovakia, unrelated); MA-S blocks "Telco Antennas Pty Ltd" (Australia, unrelated); MA-S "Mutelcor GmbH" (unrelated) [Confirmed] — the IEEE MA-L registry, the IEEE MA-S registry
- Allocated / registration date
- Unknown — IEEE publishes no assignment/registration date for OUI/MA-L blocks; any third-party "date registered" figure (e.g. maclookup.app) is a database artifact, not an IEEE fact [Confirmed] — n/a (absence is the finding)
- IANA reference
- not applicable — OUI/MAC block registration is an IEEE Registration Authority function, not IANA; no RFC reference exists [Confirmed] — n/a
- Security context
- Unknown — no vendor-specific CVEs/advisories found for Telco Systems or BATM Networks equipment in this research pass [Unknown] — WebSearch (negative result)
