Appendix A: Patches and advisements
• The patch is not required for ITG Trunk 2.x.26G or ITG Trunk 2.x.25
interworking with IP Trunk 3.01.22, as these older versions of ITG
Trunks do not support the CSE format.
• The patch is not required when upgrading a few IP Trunks to IP Trunk
3.01.22 to interoperate with other nodes running IP Trunk 3.00.53, ITG
Trunk 2.32.26G, and ITG Trunk 1.0.43, and the format received is SL1,
SL1 ESN5, or QSIG. If the format received is CSE, which is not
supported on ITG Trunk, the patch is required.
For pairs of nodes in this scenario, the following applies:
• IP Trunk 3.00.53 interworking with 3.01.22 - the patch is required if the
CSE format is used.
• IP Trunk 2.32.26G interworking with IP Trunk 3.01.22 - no patch is
required.
• IP Trunk 1.0.43 interworking with IP Trunk 3.01.22 - no patch is
required.
