FC Unframed consists in sending a frame without EOF (End Of
Frame).
FC Unframed with the Enable Sync check box selected consists
of continuously sending frames that last approximately 1 sec.
Thus sending a sync pattern that regularly keeps the link
synchronized. Frames are separated by the minimum Inter-Frame
Gap (IFG).
FC Framed Layer 1 consists of sending a valid frame (8 to 2148
bytes) without Header, and CRC (Cyclic Redundancy Check).
Refer to Size on page 229 for more information on the frame size.
FC Framed Layer 2 consists of sending a valid frame (36 to 2148
bytes) including Header and CRC. Refer to Size on page 229 for
more information on the frame size.
Note: There is nothing to configure for FC Framed Layer 1 and FC Framed
Layer 2.
