Concord Data Systems

Concord Data Systems was a telecommunications equipment manufacturer founded in 1979 by Ken Miller (previously Director of Modem Development at Codex) and based in Marlborough, Massachusetts. The company designed and sold high-speed full-duplex dial-up telephone modems for transmitting digital computer data in analog form over the public switched telephone network. As the modem hardware market commoditized, the business pivoted from industrial data communications to the emerging market for network performance management software and was renamed Concord Communications, best known for its eHealth network management suite. Battery Ventures was one of thirteen investors in that company. Concord Communications was acquired by CA (Computer Associates) on 2005-06-07 for approximately $350 million ($330M cash plus roughly $20M of assumed net debt); CA was itself acquired by Broadcom in 2018. Concord Data Systems is therefore a historical, defunct entity: it operates no website, no developer portal, and no API surface today. It is retained in the API Evangelist network as a venture-portfolio lineage record only.

Concord Data Systems is profiled on the APIs.io network. Tagged areas include Company, Defunct, Networking, Telecommunications, and Modems.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/concord-data-systems: open an issue to ask a question, or submit a pull request to add artifacts.
