XRT75R12D
TWELVE CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT WITH SONET DESYNCHRONIZER
The user can accomplish this by executing of the following step.
Then the user should clear Bit D2 (JA1) to "0" and set Bit D0 (JA0) to "1", within the Jitter Attenuator Control
Register, as depicted below.
Once the user accomplishes this step, then the Jitter Attenuator (within the LIU) will be configured to operate
with a very narrow bandwidth.
The user can accomplish this by executing the following step.
Then the user should set Bit D1 (JATx/JARx*) to "1", within the Jitter Attenuator Control Register, as depicted
below.
Finally, if the user intends to use the LIU in an Application that is required to reacquire proper SONET and DS3
traffic, prior within 50ms of an APS (Automatic Protection Switching) event (per Telcordia GR-253-CORE), then
the user should clear Bit 4 (SONET APS Recovery Time Disable), within the "Jitter Attenuator Control"
Register, to "0" as depicted below.
d. Configure the Jitter Attenuator (within each of the channels) to operate in the Transmit Direction.
c. Configure each of the channels within the LIU to operate in the SONET De-Sync Mode
e. Enable the "SONET APS Recovery Time" Mode
If the LIU has been configured to operate in the Host Mode
If the LIU has been configured to operate in the Host Mode.
