What This ECCN Covers

ECCN 5D001 controls "software" for the development, production, or use of the telecommunications equipment and features controlled under 5A001 (and related entries), as well as certain software that provides controlled telecom characteristics. Because part of Category 5 Part 1 covers interception capability, the entry carries a Surreptitious Listening reason alongside National Security and Anti-Terrorism.

Who needs to check this?

Telecom software developers, firmware suppliers for controlled communications equipment, and vendors of network-management or signal-processing software tied to 5A001 hardware.

Compliance tip

Identify which 5A001 function the software enables — controls track the underlying equipment, and SL-related software faces broad licensing. Verify the §734.7 "published" exclusion for any publicly available code, and confirm the License Exception paragraph before relying on an exception.
