connectedinstead of Insert A Register if DCG = 0, and insteadof Insert A and
Insert B Registersif DCG = 1.
WhenSGV goes to ”1”, the currentcontents of Command Register (CMD) is taken
into account by the generator.In this case, Command Registermeans :

If generatortransmits sequenceinstead of Insert B register, the data
rate for this channel is given by BCH1/0

If DCG = 1, the datarate of PRSgenerator is the sum of datarate Insert B
channel and Insert A channel.
If DCG = 0, the datarate of PRSgenerator is equal to data rate of InsertA channel.

After RESET 00 (H).
If the Pseudo Random Sequence Analyser is validated (SAV = 1), this register indicates the number of
errored bits received after the synchronisation of the Pseudo Random Sequence. When Error Counter
Register indicates all ”1”s, the synchronisationis lost. After reading by the microprocessor, ECR is put to
”0”.
