!X6=xxx xxx = 0 - 255 Set CUG (Closed User Group) identifier (255 = no CUG)
!X7=xxx xxx = 4 - 256 Set packet size (must always be multiple of 2)
!X8=n n = 0 - 15 X.121 number of address prefix digits.
!X9=n n = 0 - 15 X.121 number of address postfix digits.
!X10=n n = 0 - 255 Add persist time interval for D channel in seconds (Default value is 5
seconds)
!X11=n n = 0 – 100 Add threshold as a percentage of the total 9600 bits/sec (e.g n=40%,
50%, 60% e.t.c) value must be assigned without “%” sign.
!X12=n n = 0 – 255 Sub persist time for the First B channel. Value is assigned in seconds
(Default value is 60 seconds).
!X13=n n = 0 – 64 Sub threshold rate for the first B channel. Value is assigned in kbits/sec.
(Default value is 4 kbits/sec).
!X14=n n = 0 – 255 Add persist time for the first B channel. Value is assigned in seconds.
(Default value is 20 seconds).
!X15=n n = 0 – 64 Add threshold rate for the first B channel. Value is assigned in kbits/sec.
(Default value is 52 kbits/sec).
!X16=n n = 0 – 255 Sub persist time for the second B channel. Value is assigned in seconds.
(Default value is 40 kbits/sec).
!X17=n n = 0 – 64 Sub threshold rate for the second B channel. Value is assigned in
kbits/sec. (Default value is 48 kbits/sec).
!X? By typing this command you can see all the parameters of X.25 (including
AO/DI).
!P Enable PAD (Packet Assembler Dissembler) mode in X.25
