Description
Normal State
Command Memory or Auxiliary Auto Reset.
If CM = 1 (Bit of Command Register):
the six lower bits of command Register and the eight bits of Source Register are stored
into each address of command Memory.
If CM = 0 (Bit of Command Register) :
the eight bits of Source Register are stored into each address of Monitor Auxililary
Memory and the six lower bits of Source Register are stored intoCommand/Indicate
Auxilliary Memory.
The 16 C/I and Monitor channels are ready to transmit and to receive data.After
AutoReset, BUSY and T0 goes to ”0”.
Auto Test. This function is reserved for manufacturer.
- The Pseudo Random Sequence generator is connected instead of Insert A Register and
Pseudo Random Sequence Analyzer is connected instead of Extract A Register.
- The Command Memory is loaded thanks to a special algorithm in order to switch the
sequence provided by the generator into TSO of PCMO, then the contents of TSO of
PCMO into TS1 of PCMO, then the contents of TS1 of PCMO into TS2 of PCMO and
so on.
Finally, the contents of TS31 of MUX1 are taken into account by the Pseudo Random
Sequence Analyzer.After loading Command Memory, 193 switching are set up in real
time.The analyzer receives the Pseudo Random Sequence from the generator after
switching.
If LP = 1, the loopback is internal.
If LP = 0, an external loopback must be performed. So, Command Memory and Data
Memory can be checked in the same time.
Reserved. Initialise CM so that the content of each input Time Slot t of input multiplex m is
switched to output Time Slot t of output multiplex m

New EXTRACT.
When NEWE = 1, EXT interrupt is generated only if a new word is loaded into
EXTRACT Registers (A or B).
TIM
Timer, associated to INS of INT Register and to TIMO/1 of CPOF register.
TIM = 1 TIM0/1 bits of CPOF register are taken into account
TIM = 0 an interrupt is generated each 125 µs.
