Caveats
Review the notes listed below before deploying the ONS 15454. 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.

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 not be resolved. 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 not be resolved.

An optical connector and optical attenuators inserted into the SFP may force the fiber against the shelf
door when it is closed. Use the following types of optical connectors and optical attenuators when
