Caveats
This issue is resolved in Release 8.0.
CSCed18803
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 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
connecting to the SFP:

Jitter Performance with XC10G
During testing with the XC10G, jitter generation above 0.10 UI p-p related to temperature gradient
testing has been observed. This effect is not expected to be seen under standard operating conditions.
Changes are being investigated to improve jitter performance in a future release. Tracking numbers
related to this issue include CSCdv50357, CSCdv63567, CSCdv68418, CSCdv68441, CSCdv68389,
CSCdv59621, and CSCdv73402.

When using KLM type fuses with specific types of fuse and alarm panels, the PWR-REDUN alarm may
not be displayed once the fuse is blown. A KLM fuse does not have a blown fuse indicator built into it.
As a result, the blown fuse detection circuitry on the FAP may continue to provide voltage on its output
despite a blown fuse.
