Hence, activation from PT or TE is not possible.
Test Mode
The test signal (it
burst mode technique normally employed on the U interface is suspended in this state
and the test signals are transmitted continuously.
Pending Deactivation
To access any of the conditional states from any of the above unconditional states the
pending deactivation state must be entered. This occurs after the receipt of a DR
command. In this state the awake detector is activated and the state is exited only when
the line has settled (i.e. INFO 0 has been detected for 2 ms) or by the command DC.
Unconditional States
Reset
This state is entered unconditionally after a high appears on the RST pin, a corrupt IOM
frame is acknowledged (if two subsequent IOM frames have different number of DCL
clocks) or after the receipt of command RES (software reset). The analog section is
disabled (transmission of INFO 0) and the U
which originally invoked the state. TM2 causes single alternating pulses to be
transmitted (it

Conditional States
Wait for DR
This state is entered from the pending deactivation state once INFO 0 or DC has been
identified. From here the line may be either activated, deactivated or a test loop may be
entered.
Deactivated
This is the power down state of the physical protocol. The awake detection is active and
the device will respond to an INFO 1w (wake signal) by initiating activation.

command will always result in the pending deactivation state being entered.
