3.3.5 Interframe Space
Figure 3.7 Structure of the Overload Frame [19].
This frame is used to separate the Data and Remote Frames. The Data and the Remote
Frames, whichever frame (Data, Remote, Error, or Overload Frame) may have been transmitted
prior to them, are separated from the preceding frame by an inserted Interframe Space.
However, no Interframe Spaces are inserted preceding Overload and Error Frames. Figure 3.8
shows the structure of the Interframe Space for nodes that are not ‘error-passive’ or have been
the receiver of the previous message. For ‘error-passive’ nodes which have been the transmitter
of the previous message, there is an extra bit field called Suspend Transmission. This structure is
shown in Figure 3.9.
