Configuring X.25
8-13
Preferential CUG
is a default CUG for the port. Any calls that do not specify a CUG will default to this
one if
Preferential CUG Flag
is
Y
. A new port has CUG
0
specified here.
Incoming Access Allowed
determines whether this port will be allowed to receive calls from outside its CUGs.
Outgoing Access Allowed
determines whether this port will be allowed to make calls outside its CUGs.
Dial Port Parameters
Dial Support
specifies whether this port is connected to a dial modem and, if so, whether connec-
tions will be initiated through dial-in or dial-out calls. (Signaling differences prevent
configuration for both dial-in and dial-out on the same port.)
A dial-out port will establish a link only when an outgoing X.25 call is placed, at
which time the port will raise DTR and the attached modem will dial a stored number
to a remote modem to establish an X.25 connection. A dial-in port will establish a link
only when a call is received.
If this port is configured as a network trunk, the value for
Dial Support
must be
None
.
Inactivity Timer
will be started as soon as there are no active connections on a dial port. (It has no
function on a non-dial port.) If no new connections are established before the period
expires, the port will be disabled until the next call is placed, if a dial-out port, or the
Disconnect Timer
expires (see next entry), if a dial-in port.
Disconnect Timer
is the length of time a dial-in port will remain disabled after expiration of the Inactivity
Timer.
Line Setup Timer
is started when the port enters
Linkup
state. If the timer expires before there is a
response from the other end, the port will enter
Failed
state.
