Configuring X.25 8-11
T23 Clear Timer
will be started when the port issues a Clear Request, and stopped (and reset) when a
Clear Confirmation or Clear Indication is received. If the timer expires, the port will
retransmit the Clear Request.
DTE Restart Retry Count
is the number of times a Restart Request from the logical DTE will be transmitted.
(The DTE will stop issuing the request on receipt of a Restart Confirmation or Restart
Indication.) If the
Restart Retry Count expires, restart and recovery procedures should
be initiated.
DTE Reset Retry Count
is the number of times a Reset Request from the logical DTE will be transmitted. (The
DTE will stop issuing the request on receipt of a Reset Confirmation or Reset Indi-
cation.) If the
Reset Retry Count expires, restart and recovery procedures should be ini-
tiated.
DTE Clear Retry Count
is the number of times a Clear Request from the logical DTE will be transmitted. (The
DTE will stop issuing the request on receipt of a Clear Confirmation or Clear Indi-
cation.) If the
Clear Retry Count expires, recovery procedures should be initiated.
CUG Parameters
Preferential CUG Flag
specifies whether the port has a preferential CUG if the port belongs to any CUGs.
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
