The Far End Block Error Counter Register contains the FEBE value. If the register is
read out it is automatically reset to ‘0’.
Data Sheet
If in state Transparent the DLB-loopback is closed from IOM- to IOM, then C/I-code
’DC’ instead of ’AI’ is issued on the IOM
If in state Transparent the non-transparent LBBD-loopback is closed from U- to U,
then C/I-code ’DC’ instead of ’AI’ is issued on the IOM
correct C/I-code ’AI’ can be read from register UCIR.

Close LBBD, LB2, LB1 Towards U or Towards IOM
– Switch that selects whether loopback LB1, LB2 or LBBD is closed
– the setting affects all test loops, LBBD, LB2 and LB1
– an individual selection for LBBD, LB2, LB1 is not possible
0 =

Close Complete Loop (B1, B2, D) Near the System Interface
the direction towards the loop is closed is determined by bit ‘U/IOM’
0 =
1 =
Close Loop B2 Near the System Interface
the direction towards the loop is closed is determined by bit ‘U/IOM’

1 =
Close Loop B1 Near the System Interface
the direction towards the loop is closed is determined by bit ‘U/IOM’
