ADDITIONAL INFORMATION
- Special case – transit: a call arriving on DLTx/Tx/TL/ATL is automatically routed by the system to a
DLTx/Tx/TL/ATL trunk group. In this case, the line used for the incoming call acts as a gateway with
respect to barring; its own link category is used rather than that of the trunk group to which it be-
longs.
- The emergency numbers predefined in the software on leaving the factory are valid regardless of
the barring mechanisms.
