connected instead of Insert A Register if DCG = 0, and instead of Insert A and

Insert B Registers if DCG = 1.

When SGV goes to ”1”, the current contents of Command Register (CMD) is taken

into account by the generator. In this case, Command Register means :

BCH1

BCH0

ACH1

ACH0

BCH1/0

Insert B channel 1/0.

If generator transmits sequence instead of Insert B register, the data

rate for this channel is given by BCH1/0

BCH1

BCH0

8 kb/s

16 kb/s

32 kb/s

64 kb/s

ACH1/0

Insert A channel 1/0

If generator transmits sequence instead of insert A Register, the data rate for this

channel is given by ACH1/0.

ACH1

ACH0

8 kb/s

16 kb/s

32 kb/s

64 kb/s

If DCG = 1, the data rate of PRS generator is the sum of data rate Insert B

channel and Insert A channel.

If DCG = 0, the data rate of PRS generator is equal to data rate of Insert A channel.

ERROR COUNTER REGISTER (ECR)

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

”0”.
