The following example explains the use of a state diagram by an extract of the LT-state
diagram. The state explained is the “Deactivated” state in LT-mode.
The state may be entered by either of three methods:
– From state “Receive Reset” after time T7 has expired (T7 Expired)
– From state “Tear Down” after the internal transition criterion “LSU” is fulfilled
– From state “Reset” or “Test” after the C/I-command “DR” has been sent on DIN
The following information is transmitted:
– SL0 is sent on the U-interface
– No overhead bits are sent
– C/I-message “DI” is issued on DOUT
The state may be left by either of the following methods:
– Leave for state “Awake” after NT wake up tone (TN) was detected and the C/I-code
– Leave for state “Alerting” after C/I-commands “AR”, “ARX”, “AR0” or “UAR” were
– Leave for state “Reset for Loop” after C/I-command “ARL” was received
Combinations of transition criteria are possible. Logical “AND” is indicated by “&” (TN &
DC), logical “OR” is written “or” and for a negation “/” is used. The start of a timer is
indicated with “TxS” (“x” being equivalent to the timer number). Timers are always
started when entering the new state. The action resulting after a timer has expired is
indicated by the path labelled “TxE”.
The sections following the state diagram contain detailed information on all states and
signals used. These details are mode dependent and may differ for identically named
signals/states. They are therefore listed for each mode.
