Introduction
Introduction
These release notes summarize the functions of the Cisco MGX 8240 Private Line Service Gateway
switch software, Release 2.2.0.3. These notes describe new features and enhancements as well as a list
of known caveats that have been fixed and verifiedsincethe previous deployed Release (1.1.2.10). The
document also lists open caveats.
These notes are intended for customer functional and operational groups and Cisco System Engineers
responsible for installing and provisioning the Cisco MGX 8240 Private Line Service Gateway.
New and Changed Information
The Cisco MGX 8240 Private Line Service Gateway systems previously shipped are to be upgraded to
the new switch software.
The purpose of this release is to resolve problems found in the switch functions. Therefore, there are
no new features as part of this release.
The following fixes and enhancements have been incorporated into Release 2.2.0.3:
• Support for APS protected Channelized Access OC3 interface
• Major rework and improvement of redundancy
• Support of 2016 DS0 circuits
• SNMP trap IP address changes and enhancements
• CES connection loopback towards TDM or ATM
• Connection BERT towards TDM or ATM
• OAM loopback delay test
• DS1 Out-Of-Frame Stats
• Connection based control of Loss of Cells reporting
• T1 SF and ESF loopback support
• Improved bootup diagnostics
Upgraded Products
The software upgrade procedure supports the following Switch Software Releases:
• 1.1.2.10 (general release of 3/5/99)
• 2.1.0.6 (general release of 8/11/99)
• 2.2.0.1 (genera release of 9/9/99)
Note All Releases prior to Release 1.1.2.10 must first be upgraded to Release1.1.2.10 using the
upgrade procedure for Release 1.1.2.10, before this Release can be applied.
Before the Cisco MGX 8240 CPE software can be upgraded, the VCLI must first be upgraded to Version
2.1.0 or higher. Separate documents provide release notes for the VCLI and information on upgrade
procedures for the VCLI.
