Link Configuration Screens
Link Configuration: LAPBMUX Link Data
Default value: 20
Range: 1–255 retries
Physical interface:
RS-232 is a standard electrical lnterface between Data
Terminal Equipment (DTE) and Data
Circuit-Termination Equipment (DCE) such as modems
or DSUs. RS-232 is used for asynchronous data transfer
as well as synchronous links such as SDLC, HDLC,
Frame Relay and X.25.
The V.35 interface was originally specified by CCITT as
an interface for 48kbps line transmissions. It has been
adopted for all line speeds above 20kbps.
Select the interface that matches the other end.
Connect timeout:
During link initialization, this value specifies the
amount of time the MUX card will wait for a response
from the remote station. If this time is exceeded, it is
assumed that the remote station is not responding.
Default value: 900
Range: 5–900 seconds or 0 (0 means disabled)
Adapter timeout:
This is a handshake sequence between the host and its
MUX card.
Default value: 10
Range: 5–900 seconds or 0
Clock source:
Specifies the origin of the synchronous timing signals.
If the parameter is set to Internal, the adapter supplies
the required timing signals. If the parameter is set to
External, an external network device supplies the
required timing signals. If the adjacent link station is
providing the clock source, set this parameter to
External.
Default value: external (1)
Options: internal (0), external (1)
Auto hangup timer:
Intended primarily for use with certain European
public telephone systems. If set, the driver will
periodically attempt to hang up the local modem phone
