To define the Frame type for the main E1 link, press 1.
The current frame type setting is CCS. To change it enter 1~3. Press ESC to exit and leave the
setting unchanged. Press ESC. Press 2 to change the CRC-4 setting.
The current setting for CRC-4 is Off. To turn on, press 2. To exit without changing, press ESC.
Press 3 to define the Cascade Mode.
In Cascade mode, the unused timeslots are not filled with idle code. Instead, they pass through
their received data transparently. This allows for 'Drop&Insert' or Cascading of multiple ETU-01A
units to build up a type of multiplexer where the entire E1 bandwidth can be divided between
different logical units. This is a simple way to split E1 bandwidth over 2 data communication
interfaces. However, we recommend using our ETU02-MUX with multiple (4) data port module
slots for multiplexing applications.
