Cisco Cisco ONS 15454 SDH Multiservice Provisioning Platform (MSPP)

This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 
15454 SDH Release 6.0.3 since the production of the Cisco ONS 15454 SDH System Software CD for 
Release 6.0.3.

No changes have been added to the release notes for Release 6.0.3.

Review the notes listed below before deploying the ONS 15454 SDH. Caveats with DDTS tracking 
numbers are known system limitations that are scheduled to be addressed in a subsequent release. 
Caveats without DDTS tracking numbers are provided to point out procedural or situational 
considerations when deploying the product.

The STM1E-12 card is not supported in this release. This card will be supported in a future release. 
Caveats herein pertaining to this card also do not apply.

Rarely, the non-enhanced Muxponder unit does not pass Jitter Tolerance test from Trunk port to client 
port as per ITU-T G.825, 2 Mb/s mask, at the 10 Hz specific setpoint. The Muxponder should be 
configured with G.709 Off, FEC Off and Trunk signal provided by external Jitter test box, and the unit 
client port output monitored for errors, to see this issue. This issue will be resolved in a future release. 
Note, however, that in normal network configurations the muxponder is operated with G.709 and FEC 
turned on, and the jitter tolerance tests pass.

Under specific conditions the non-enhanced MXPD does not pass the Telcordia GR-253/G.825 Jitter 
generation mask test on 10G TX Trunk port. The 2.5 G TX Client jitter generation is always within mask 
and does not exhibit this issue. This occurs only when, in SONET mode, there is no FEC, no G.709, and 
client interfaces are looped back, with non-synchronous clocking, and the jitter testbox TX connected to 
Trunk RX port, while the jitter testbox RX is connected to the Trunk TX port. The jitter testbox TX clock 
recovers from RX with an additional 5 ppm offset added. This issue will be resolved in a future hardware 
release.
