W6692A
- 22 -
turn off and stay at this state if INFO 0 is received on the S line. The turn off time is approximate 93
mS. The ECK command must be issued to activate the clocks.
F3 Deactivated with clock
This state is identical to "F3 Deactivated without clock" except the internal clocks are enabled. The
state is entered by the ECK command. The clocks are enabled approximately 0.5 mS to 4 mS after
the ECK command, depending on the crystal capacitances. (It is about 0.5 mS for 12pF to 33pF
capacitance).
F3 Awaiting Deactivation
The W6692A enters this state after receiving INFO 0 (in states F5 to F8) for 16 mS (64 frames). This
time constant prevents spurious effect on S interface. Any non-INFO 0 signal on the S interface
causes transition to "F5 Identifying Input" state. If this transition does not occur in a specific time (500
- 1000 mS), the microprocessor may issue DRC or ECK command to deactivate layer 1.
F4 Awaiting Signal
This state is reached when an activate request command has been received. In this state, the layer 1
transmits INFO1 and INFO 0 is received from the S interface. The software starts timer T3 of I.430
when issuing activate request command. The software deactivates layer 1 if no signal other than
INFO 0 has been received on S interface before expiration of T3.
F5 Identifying Input
After the receipt of any non-INFO 0 signal from NT, the W6692A ceases to transmit INFO 1 and
awaits identification of INFO 2 or INFO 4. This state is reached at most 50
μ
s after a signal different
from INFO 0 is present at the receiver of the S interface.
F6 Synchronized
When W6692A receives an activation signal (INFO 2), it responds with INFO 3 and waits for
normal frames (INFO 4). This state is reached at most 6 mS after an INFO 2 arrives at the S
interface (in case the clocks were disabled in "F3 Deactivated without clock").
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 at most 0.5 mS after reception of INFO 4. From state "F3
Deactivated without clock" with the clocks disabled, state F7 is reached at most 6 mS after the
W6692A is directly activated by INFO 4.
F8 Lost Framing
This is the state where the W6692A has lost frame synchronization and is awaiting resynchronization
by INFO 2 or INFO 4 or deactivation by INFO 0.
