Technical specifications publicly available for manufacturers to reference are provided in PDF format only. Issued specifications undergo changes through an open Engineering Change Process.
Consistent with current practice, Engineering Change Notices (ECNs) are considered to be part of the applicable specification, even though they may not yet be included in a published version of that specification. Therefore, for the purpose of compliance testing, CableLabs considers the current version of the specification to consist of the most recent, published version of the specification as it appears on CableLabs' Web site, and any ECNs approved since the specification publication but not yet incorporated into the specification. Note that ECNs are considered mandatory for Certification/Qualification in the Certification Wave or effective date as indicated in the ECN.
Once ECNs are incorporated into the specification and the next version of the specification has been published, those incorporated ECNs will be removed from the public Web page and archived in DocZone. The public Web page will state if there are no ECNs for a particular project.
