Transmission on U-Interface
– In transmit direction register M4WMASK decides which M4, M5 and M6 bits are controlled
– The DFE-Q V2.1 transmits a given bit polarity as long as it is not changed by a new MON-2
– The spare bits (M51, M52, M61) are set to binary ’1’ when leaving a power-down state. No further
Reception on U-Interface
– In the receive direction (on DOUT), the incoming M4, M5 and M6 bits are checked by the
– In order to notify the controller of the initial system status, one MON-2 message is issued
– The DFE-Q V2.1 will not issue MON-2 messages while the programmed validation criterion

Local functions are controlled via MON-8-commands. Local functions comprise e.g.
reading block error counters, stimulating test functions, etc. MON-8-commands have the
lowest priority and may be passed at any time and need to be transferred only once.
Latching
Latched commands in the NT must be disabled explicitly with the “NORM” command.
Internal transfer commands (RBEN/F, RID) are not latched. Test and activation control
commands (PACE, PACA, CCRC, LB1/2, LBBD) will be latched.
The following tables give an overview of structure and features of commands belonging
to this category.
MON-8 Structure
The following local commands are defined. If a response is expected, it will comprise 2
bytes. In the two-byte response the first byte will indicate that a MON-8 answer is
transmitted, the second byte contains the requested information.

selected validation mode. A MON-2 message defining all 12 bits is issued if a change of at least
one single bit other than the FEBE bit has been approved valid. Therefore a MON-2 message is
sent not more often than once per superframe (12 ms interval).
