4.3.7
When the terminal requests to activate the S-interface (U-interface already active) two
cases can occur:
In the first case the exchange has retained control over the S-interface activation. Then
S-activation can proceed only after the explicit permission by the exchange with AR. This
situation is discussed in this section under “case 1”.
In the second case the exchange is not requested to send AR in order to continue
activation. This situation is described in “case 2” of this section.
The TE initiates complete activation with INFO 1 leading to “SAI” = (1). Case 1 requires
the exchange side to acknowledge the TE-activation by sending C/I = “AR”, Case 2
activates completely without any LT-confirmation. The TE recognizes no difference
between the two types, the procedure on NT-side consequently is identical in both
cases.
