21. TRANSMIT ELASTIC STORE SLIP
22. RECEIVE ELASTIC STORE
23. ELASTIC STORE OPERATION IN E1 MODE
24. DEVICE ID REGISTER READS INCORRECT VALUE
Description:
When the transmit elastic store is enabled and a slip occurs, the transmit framer restarts the insertion
of the multiframe alignment pattern. This may cause the remote port to lose sync.
Work Around:
There is no known work around for this issue.
Description:
When operating in T1 mode with the receive elastic store enabled and RSYSCLK at 2.048MHz, blue
alarms and Loop codes will not be detected.
Work Around:
There is no known work around for this issue.
Description:
When operating in E1 mode with either elastic store enabled, data in the first four channels can be
corrupted if both the input and output elastic-store clocks are precisely edge aligned.
Work Around:
There is no known work around for this issue.
Description:
The device ID register (IDR) contains an incorrect value of B0h, which would have been reserved for
revision A1.
Work Around:
There is no known work around for this issue.
