Pattern type
Select the pattern to be inserted in the transmitted signal. Refer to Pattern
type in "E1 Setup and Status". Available patterns are:
Off
User [32] bit, User [2048] bit
PRBS 9 to PRBS 31
QRSS 20
Fox Pattern, Fox (CMA3000)
All 0's, All 1's
Alternating 1:1, Alternating 1:3, Alternating 1:7, Alternating 3:24
Touch 'Normal' or 'Inverse' pattern type.
Touching the 'ANSI standard' button will apply ANSI/IEEE 1007 recommended
Pattern type for 45 Mbit data rates (PRBS 23 Inverse).
User pattern
User pattern field is enabled if Pattern type is set to User [32] bit or User
[2084] bit. Touch the User pattern field and use the launched Pattern
Editor dialog box to define the user pattern. Depending on the selected
pattern type, different user pattern setup options will be available.
The length can be any length from 1 bit to 32 bits or from 1 bit to 2048 bits.
FEAC Code
When 'Frame type' is set to C-Bit, allows you to specify the six bits of FEAC
(Far-End Alarm and Control) channel code.
