Cisco Headend System Release 2.5 技术参考
March 2004
Operations Alert Bulletin
System Release Obsolescence
Introduction
Cisco has made significant improvements with the performance of each successive
system release. For example, System Release (SR) 1.5.1 improved overall system
performance and System Release 2.2.0/3.2.0 incorporated Cisco’s CableCARD
™
functionality and added new EAS (Emergency Alert System) codes. Taking these
improvements into account, Cisco has decided to discontinue several older system
releases.
Purpose
This alert bulletin serves as notification to system operators that several system
releases will be discontinued. In addition, the benefits of upgrading to a current
system release and the future disposition of the supporting publications for these
discontinued system releases are discussed.
Audience
This alert bulletin is intended for all Cisco customers who have System Release 1.2.x,
1.4.x, 1.5.0, 2.1.0, 2.1.1, 3.0.0, and 3.0.1 software installed and running at their sites.
