ATM Switch Network Configuration Manual
Signalling
The following two tables summarize the above information. Table 7.1 highlights the actions
taken based on the configurations of the FORE switches on both sides of an interface.
ForeThought versions prior to ForeThought 4.1.x always default to UNI 3.0. Both UNI 3.1 and
UNI 4.0 use SSCOP version 31.

Both stacks initialized as SSCOP 31 if both sides support UNI
3.1 or UNI 4.0; otherwise, both sides are initialized to SSCOP
30. If both sides support PNNI then, both sides are initialized
to SSCOP 31 and the version is set to PNNI 1.0.
