Initialization (LT side)
Acknowledgment (NT and LT side)
Notify of Corrupt CRC (NCC)
If the EOC Auto mode is used on the NT side (see "EOC Auto/Transparent Mode", page
55) this command requests the NT to disable the NEBE-counter and MON-1 NEBE
indications.
In the EOC Transparent mode the IEC-Q will not react to this command.
This command is a predefined EOC command which can be controlled by the MON-0
message issued on the LT side downstream (see "Access to EOC of U-Interface", page
110).
Initialization (LT side)
Acknowledgment (NT and LT side)
Return to Normal (RTN)
If the EOC Auto mode is used on the NT side (see "EOC Auto/Transparent Mode", page
55) this command requests the NT to disable all previously received EOC commands.
In the EOC Transparent mode the IEC-Q will not react to this command.
This command is a predefined EOC command which can be controlled by the MON-0
message issued on the LT side downstream (see "Access to EOC of U-Interface", page
110).
