Tx Turn Around Time
The time, in milliseconds, between receiving a frame from an outstation and transmission
back to the same station. If this parameter is set to
0
, this is disabled and the router can
respond immediately. The minimum non-zero value is
10ms
.
Mode
Defines the mode in balanced links, such as HDLC. In unbalanced links such as SNA/SDLC, the
mode is defined by being master or the station.
N400 counter
A standard LAPB retry counter. The default value is
3
and it should not normally be necessary
to change this.
RR Timer
A standard LAPB/LAPD
Receiver Ready
timer. The default value is
10,000ms
(10 seconds) and
it should not normally be necessary to change this.
T1 timer
A standard LAPB timer. The default value is
1000
milliseconds (1 second) and under normal
circumstances, it should not be necessary to change it.
T200 timer
A standard LAPB re-transmit timer. The default value is
1000
milliseconds (1 second) and
under normal circumstances, it should not be necessary to change it.
Window Size
The X.25 window size. The value range is from
1
to
7
with the default being
7
.
Disconnect link if there has been no activity for
x
seconds
The length of time, in seconds, before the link is disconnected if there has been no activity. If
this parameter is
0
or not specified, then the inactivity timer is disabled. It is useful to set this
to a short period of time, for example, 120 seconds, when an LAPB instance is being used over
ISDN. This timer can be used as a backup hang-up timer, thus saving ISDN call charges. When
LAPB is being used on a synchronous port, this parameter should normally be set to
0
.
