the line controller (here an LIU) automatically inserts a zero after transmitting five
consecutive ones. The converse is occurs when the line controller receives data: a zero
following five consecutive ones is stripped from the input stream.
An application cannot request an abort sequence. If an abort sequence occurs in either
an incoming or an outgoing frame, the ADCCP protocol module informs the
application (which sent or received the data) that the frame was aborted.
Line-Configuration Options The line-configuration options that you define at system generation specify:
Parts of the electrical interface
Frame formats
Resource utilization
Error-handling strategies for the line
Most of your choices will depend on the hardware features used on the link; for
example, the characteristics of your modems, the delays built into some terminals, the
character code a terminal or mainframe uses, or the expected quality of a line. A few
of your choices will depend on tuning or architectural considerations; for example, the
most efficient size of a frame or whether you should operate two mainframes as peers
rather than as master and slave.
Table 1-2 lists the line-configuration options in five functional categories. For detailed
descriptions of these options, refer to the System Generation Manual for CP6100 or see
Table 6-2 in Section 6, “Requests and Responses,” of this manual.
