Description
This Link
(LMLSTREC.TL)
0
This parameter is a two-octet
primary identifier for the local
link, within the extended link,
whose values are constrained.
The DLE uses it to record the
local link ID. Its default
uninitialized value is zero, which
does not permit a bridge to
forward to another link. Its range
is 0, and 4096 to 65279.
Minimum Inter Pdu
Delay
(LMLSTREC.MID)
16
Specifies the minimum duration
for an interval of non-
transmission that a DLE
provides after either receiving or
transmitting a DLPDU. It is
measured in units of the
transmission duration of one
octet. The default value is 16
and its range is 0 to the smaller
of 120 or (Maximum Response
Delay -1) x Slot Time.
Number of
Consecutive Unpolled
(LMLSTREC.NUN)
196
Specifies the number of
consecutive unused 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 0 to 228 and its
default value is 196
Preamble Extension
(LMLSTREC.PMBEXT
N)
0
Specifies an extension period
for the preamble. A preamble is
transmitted at the beginning of
each Physical Layer Protocol
Data Unit (PhPDU) to
synchronize bit times. The
period may be extended, but not
reduced. It is an Unsigned8
variable with allowable values
between 0 and 7.
