Caveats
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.

DDTS # CSCed18803
Rarely, the 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.

DDTS # CSCuk48503
Under specific conditions the 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 release.

The TXP_MR_2.5G and TXPP_MR_2.5G cards do not support TX Optical power performance
monitoring on the trunk port. To see this, go to the Optics Performance Monitoring tab of the
TXP_MR_2.5G or TXPP_MR_2.5G card, and select the trunk port. TX Optical Pwr is not shown.
