77 / 291 page  DELIC Interface Description Preliminary Data Sheet 3-21 2003-08 LT-T Mode (Conditional States) • F3 power down This is the deactivated state of the physical protocol. The receive line awake unit is active. • F3 power up This state is similar to “F3 power down”. The state is invoked by a Command TIM = “0000” (or DI static low). • F3 pending deactivation The line interface reaches this state after receiving INFO 0 (from states F5 to F8). From this state an activation is only possible from the line (transition “F3 pending deactivation” to “F5 unsynchronized”). The power down state may be reached only after receiving DI. • F4 pending activation Activation has been requested from the terminal; INFO 1 is transmitted; INFO 0 is still received; “Power Up” is transmitted in the C/I channel. This state is stable: timer T3 (ITU I.430) is to be implemented in software. • F5/8 unsynchronized At the reception of any signal the VIP ceases to transmit INFO 1, adapts its receiver circuit, and awaits identification of INFO 2 or INFO 4. This state is also reached after the line interface has lost synchronism in the states F6 or F7 respectively. • F6 synchronized When the VIP receives an activation signal (INFO 2), it responds with INFO 3 and waits for normal frames (INFO 4). • F7 activated This is the normal active state with the layer 1 protocol activated in both directions. From state “F6 synchronized”, state F7 is reached almost 0.5 ms after reception of INFO 4. • F7 slip detected When a slip is detected between the T interface clocking system and the IOM-2 interface clocks (phase wander of more than 25 µs, data may be disturbed) the line interface enters this state, synchronizing again the internal buffer. After 0.5 ms this state is relinguished. |
