Configuring X.25
8-25
In this case, other system factors will determine whether line 1,0 or line 1,2 will be
selected. If we assume 1,0 is selected, the new values of
U
will be as follows, giving
line 1,2 the next call:
Line
U
0,0
4
1,0
4
1,1
failed
1,2
2
If the database is changed and lines are added or deleted from the routing path config-
uration, or if lines become operational or not operational, the next Call Request will
trigger new
U
values based on the lines available at the moment. As operational lines
fill up their LCNs they are excluded from getting new calls. If all operational lines
have all LCNs in use, new calls will be cleared.
Subscriber Parameters
1
The software does not verify that a specified port exists. Make sure the port is configured
in the database.
Subscriber Name
identifies the subscriber to the console operator.
Routing Algorithm
allows creation of a "hunt group" of ports (see example on
page 8-24
), for the purpose
of routing per a pre-selected algorithm:
0
= Round Robin – selects ports specified cyclicly in numerical order according
to the list of Redirection Addresses. If the selected port is unreachable or con-
gested, the Call Request will be sent to the next port. (If the port becomes
available again, it will be included in its assigned position.)
1
= Alternate Route on Line Failure – selects the first port that is not in a failed
state. If the selected port does not make a connection, the call will be cleared, even
if other ports are available.
