Link Configuration Screens
Link Configuration: LAPBMUX Link Data
line, then resume awaiting a connection. This recovers
from situations in which a human or incompatible
modem accidentally dialed in during the time period,
but the local modem failed to hang up on its own after
failing to establish a connection. If a connection is
successfully established, the timer is cancelled. When
zero, the feature is disabled.
Default: 0
Range: 5–900sec
Local mode:
If the node being configured is DCE, then the node at
the other side must be DTE. If the node being
configured is DTE then the node at the other side must
be DCE.
Options: 5 = DTE, 6 = DCE
Data encoding:
NRZ: Indicates Non-Return to Zero coding
NRZI: Indicates Non-Return to Zero Inverted coding
NRZI coding unlike NRZ coding specifies that the
signal condition does not change for transmitting a
binary 1 while a binary 0 causes change of state.
Since asynchronous operation requires that the
receiver sampling clock be derived from the received
data, NRZI encoding plus zero bit insertion (for every
consecutive 5 one (1) bits) make the design of clock
recovery circuitry easier.
Default: NRZ (0)
Options: NRZ (0), NRZI (1)
Trace at startup:
Enter Y (YES) to enable link tracing, N (NO) otherwise.
This value can be overridden with the LINKCONTROL
command. If enable link tracing is selected, a trace file
name is required.
For best performance, do not enable tracing.
Default value: N
Trace file:
Required if link trace is enabled. Name of the disk file
where you want to record tracing. Must be a valid MPE
file name. Enter the file name in the format
