Citel Technologies — 00:10:01 (MA-L); scoped to single strongest registrant, collision resolved

Cycle-1 research found that the slug vendor-citel was a naming collision: the pipeline's corporate-suffix-stripping slugifier had bucketed two unrelated IEEE MA-L registrants — "Citel" (00:10:01, Loughborough, GB) and "CITEL SpA" (00:16:37, Milan, IT) — into one entry, with no single registrant covering both. Per checker instruction (registry_mismatch: no single registrant covers both prefixes (C5); a consolidated master row would misattribute 00:16:37 to Citel Technologies), this cycle resolves the disposition by selecting and scoping to the single strongest candidate — Citel Technologies (00:10:01), a UK CTI/VoIP-telephony-migration vendor with verifiable product and corporate-registry substance — and drops 00:16:37 from this entry's prefix set. This cycle also completed the research the checker flagged as missing: the second registrant, CITEL SpA (Milan), is now confirmed to be a real, substantively documented company in its own right — a physical-security/PSIM (Physical Security Information Management) software-and-hardware engineering firm founded in Milan in 1994, acquired 67% by the Sesa Group (via Base Digitale Security Solutions) on 2021-12-13 — not the France-based CITEL Group surge-protection manufacturer speculatively floated in cycle 1 (that link is now understood to be incorrect and is dropped). Because CITEL SpA has genuine company substance but is verifiably unrelated to Citel Technologies, it is excluded here as a candidate for its own future, distinctly-slugged OUI entry rather than folded into this page.

Editorial disposition (RESOLVED, was unresolved slug-collision)

select+scope the single strongest candidate — Citel Technologies, 00:10:01. The other prefix (00:16:37 "CITEL SpA", Milan IT) is dropped from this entry's prefix set; it is a verified, unrelated company with its own real substance (see below), not a shell registration, and is a candidate for its own future separately-slugged OUI entry, not folded into this page

[Confirmed as resolved decision] — this cycle's analysis, responding directly to checker note "registry_mismatch"/C5

Company identity (retained registrant)

Citel Technologies — Loughborough Innovation Centre, Loughborough, GB LE11 3EH (IEEE registry address) [Confirmed] — the IEEE MA-L registry (IEEE MA-L)

Company substance (retained registrant)

IDENTIFIABLE COMPANY WITH PRODUCT/DEVICE CONTEXT. Checked (carried forward from cycle 1, re-verified this pass): UK-founded (1995) CTI/VoIP-migration vendor; products include Portico TVA telephone-to-VoIP adapters, EXTender IP gateways, and SIP/IAX2 IP phones such as the C4110; UK entity CITEL TECHNOLOGIES (UK) LIMITED, Companies House #06592137, address-consistent with the Loughborough IEEE registry entry. A second, non-colliding OUI (00:06:E4, "Citel Technologies Ltd.", Nottingham GB) tracks the same company at an earlier address but slugifies to a separate bucket (vendor-citel-technologies) and remains out of scope for this entry [Likely] — https://www.citel.com/company/, https://find-and-update.company-information.service.gov.uk/company/06592137, https://www.citel.com/Products/

Excluded registrant (00

16:37, "CITEL SpA", Milan): IDENTIFIABLE COMPANY WITH SUBSTANCE, verified this pass — NOT a bare single-OUI registration, but confirmed unrelated to Citel Technologies. CITEL SpA (now trading as part of "Citel," a Base Digitale Group / Sesa Group company) was founded in Milan in 1994 as a physical-security-supervision software/hardware engineering firm; its Centrax open-PSIM platform (Physical Security Information Management) is described as leading the Italian PSIM market, deployed at major Italian banks, Poste Italiane, and national energy groups. Sesa acquired a 67% stake via its subsidiary Base Digitale Security Solutions on 2021-12-13. Registered address Via L. G. Columella 36, Milan MI IT 20128 (Partita IVA 11179450157) matches the IEEE registry address exactly [Confirmed] — https://www.aziendabanca.it/notizie/tecno/base-digitale-citel-a-plus, https://www.impresaitalia.info/ik00821052/citel-spa/milano.aspx, https://basedigitale.com/integrated-security-solutions/security-asset-management/centrax/, https://www.dahuasecurity.com/it/newsEvents/pressRelease/6877

Excluded-registrant correction vs. cycle 1

cycle 1 speculatively floated a possible link between the 00:16:37 Milan entity and the France-founded CITEL Group surge-protection/SPD manufacturer (citel.us / citel.de); this pass found no such connection — the Milan entity is a distinct security-software/PSIM company (Base Digitale/Sesa Group lineage), unrelated to the French surge-arrester manufacturer. That speculative link is retracted

[Confirmed retraction] — this cycle's research, sources above

Device types / usage (retained registrant, Citel Technologies)

VoIP/CTI telephony adapters, SIP/IAX2 IP phones [Confirmed] — https://www.citel.com/Products/

Registry / block size

MA-L (24-bit OUI); single block for each registrant — "Citel" (00:10:01) and "CITEL SpA" (00:16:37) each hold exactly one MA-L row; no MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) block found for either exact organization name in this pass

[Confirmed] — the IEEE MA-L registry, the IEEE MA-S registry

Date field

none recorded. IEEE's MA-L CSV export publishes no assignment/registration date for either row [Confirmed] — the IEEE MA-L registry

Third-party date caveat

maclookup.app shows a "Registration Date: 1998-04-22" for 00:10:01; this is a third-party database artifact, not an IEEE fact, and is not attributed to IEEE here [Confirmed] — https://maclookup.app/vendors/citel

Security context (retained registrant)

no vendor-specific CVE/advisory found for Citel Technologies devices in this pass; a general web/CVE search was run but no dedicated NVD/CVE-database query was made, so this is an absence-of-finding, not a confirmed-clean result [Unknown] — general web search, this pass

Org status

retained registrant (Citel Technologies, UK) — active [Likely] — https://www.citel.com. Excluded registrant (CITEL SpA, Milan) — active, now operating as part of the Base Digitale Security / Sesa Group [Confirmed] — https://www.aziendabanca.it/notizie/tecno/base-digitale-citel-a-plus
