18.2. Description
Description
Indicates the configured Data
Link Protocol Data Units
(DLPDU) Physical Layer
Overhead (PhLO) value. The
DLE uses it to account for the
Physical Layer induced delay
between the end of the last
octet of one DLPDU, as it
appears on the link, and the
beginning of the first octet of
any other DLPDU, as it appears
on the link. It is measured in
units of one octet-duration. Its
range is 2 to 63.
Indicates the configured
maximum response delay value.
It is a measure, in units of one
slot time, greater than the worst-
case period of local Physical
Entity inactivity that a DLE can
observe. The DLE uses it to
record the Link's maximum
response delay. Its range is 1 to
11.
Indicates the first unused node
address value. It is the first node
address of a series of
consecutive node addresses,
which are to be omitted from the
orderly probe of node addresses
for DLE's not specified by the
local link live list. Its range is 21
to 247.
