If the U-transceiver is only partially activated the S-interface remains deactivated. When
the partial activation is initiated by the LT-side, the exchange has two options:
• First, in case the C/I-command DC is not issued after the partial activation is complete,
• Secondly the exchange can issue DC after UAI has been received. This allows the
The NT U-transceiver is in the “Synchronized 1” state after a successful partial
activation. On DOUT the C/I-message “DC” as well as the LT-user data is sent.
While the C/I-messages “DI” (1111
transceiver will transmit “SAI” = (0) upstream. Any other code results in “SAI” = (1) to be
sent. On the U-interface the signal SN3 (i.e. 2B + D = (1)) will be transmitted continuously
regardless of the data on DIN.
The LT will transmit all user data transparently downstream (signal SL3T). In case the
last C/I-command applied to DIN was “UAR”, the LT retains activation control when an
activation request comes from the terminal (confirmation with C/I = “AR” required. With
C/I “DC” applied on DIN, TE initiated activations will be completed without the necessity
of an exchange confirmation.

is accepted. This allows the exchange to retain full control, even in case of terminal
