Activation Initiated by TE with Repeater
In order to recognize a terminal initiated activation successfully the NT-RP must be in
"Power Up" condition to provide clocks for the LT-RP. During the activation procedure
the LT-RP-signal "UAI" needs to be changed into "AI" by the control unit.

Deactivation by Repeater
The start of a deactivation procedure is passed from the LT to the NT side via Single bits
in the U-frame. These are interpreted by the LT-RP. Thereafter the deactivation process
in LT-RP and NT-RP is running mostly independent of each other as illustrated below.
No C/I-codes need to be converted by the control unit.
