Revision A1
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 W6692 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 W6692 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
W6692 is directly activated by INFO 4.
F8 Lost Framing
This is the state where the W6692 has lost frame synchronization and is awaiting resynchronization
by INFO 2 or INFO 4 or deactivation by INFO 0.
Special States:
Analog Loop Initiated
On Enable Analog Loop command, INFO 3 is sent by the line transmitter internally to the line receiver
(INFO 0 is sent to the line). The receiver is not yet synchronized.
Analog Loop Activated
The receiver is synchronized on INFO 3 which is looped back internally from the transmitter. The
indication 'TI" or "ATI" is sent depending on whether or not a signal different from INFO 0 is detected
on the S interface.
Send Continuous Pulses
A 96 KHz continuous pulse with alternating polarities is sent.
Send Single Pulses
A 2 KHz isolated pulse with alternating polarities is sent.
Layer 1 Reset
A layer 1 reset command forces the transmission of INFO 0 and disables the S line awake detector.
Thus activation from NT is not possible. There is no indication in reset state. The reset state can be
left only with ECK command.
