Appendix
Appendix A: Jitter on IOM-2
The output jitter on the IOM-2 clocks FSC and DCL/BCL may be higher than in versions
4.3 and older. The jitter on pin CLS is the same as in versions 4.3 and older. This does
not contradict any norm or specification. However in jitter sensitive applications the
system performance should be rechecked.
For PCM-2 applications - as depicted in the IEC-Q V4.3 User’s Manual 02.95 on page
44 - it is not recommended to use the IEC-Q TE V5.2 together with version 3.0 of
SICOFI-2 (PEB/F 2260). This is due to the somewhat different behavior of this SICOFI-2
version from earlier versions (see Delta Sheet, May 1996, of the PEB/F 2260).
Instead, it is recommended to use the PEB 2091 IEC-Q in NT-PBX mode for PCM-2
applications with the PEB/F 2260. The application with IEC-Q and SICOFI-2 is described
in the IEC-Q V5.2 Errata Sheet 09.97 on page 6ff.
