B.3.1 Syntax conventions
Syntax definitions use the following conventions:
• <parm> indicates that a parameter (without < and >) can be filled in by the user.
• { <opt1> | <opt2> | ... } indicates that one of various options must be chosen by the
user.
• [<options>] indicates that <options> may or may not be included in the command.
• Keywords and parameters are separated by commas.
Note: If parameters in the middle are left out, the commas must still be there as
placeholders, e.g. <parm1>,,,<parm4> - In this case parm 2 and parm 3 are left
out, but <parm4> is used. If the last parameters are left out, the commas are not
needed, e.g. <parm1>,<parm2>
• The command name and all keywords must be in upper case; most user-provided
parameters are case sensitive but may be either case.
• TE means Terminal Equipment - the equipment connected locally to the
EXPLORER 540.
