If the LIU has been configured to operate in the Hardware Mode
Then the user should tie pin 65 (SR/DR*) to "High".
c.
Configure each of the channels within the LIU to operate in the SONET De-Sync Mode
The user can accomplish this by executing either of the following steps.
If the LIU has been configured to operate in the Host Mode.
Then the user should set Bit D2 (JA0) to "0" and Bit D0 (JA1) to "1", within the Jitter Attenuator Control
Register, as depicted below.
If the LIU has been configured to operate in the Hardware Mode
Then the user should tie pin 44 (JA0) to a logic "HIGH" and pin 42 (JA1) to a logic "LOW".
Once the user accomplishes either of these steps, then the Jitter Attenuator (within the LIU) will be configured
to operate with a very narrow bandwidth.
d.
Configure the Jitter Attenuator (within each of the channels) to operate in the Transmit Direction.
The user can accomplish this by executing either the following steps.
If the LIU has been configured to operate in the Host Mode.
Then the user should be Bit D1 (JATx/JARx*) to "1", within the Jitter Attenuator Control Register, as depicted
below.
