The level 3 protocol provides a capability to indicate
the type of data being transferred between CAMPS and
SCARS II.
The character code used is the NATO 7-bit code, which
is based on the ITA no. 5.
All data exchanged between CAMPS and SCARS II is in
ACP127 format. Four types of data is transmitted and/or
received:
- normal message
- data message
- terminal to terminal comment
- display transfers
The supervisor is informed if any malfunction of the
communication line occurs. It is the responsibility
of the supervisor to take action to repair the communication.
The system will automatically maintain and control
the communication between stations by means of:
o check of link security levels at initialization.
o resetting of transmission sequence numbers.
