ISDN Connection Monitor
The ISDN Connection Monitor is activated automatically whenever
the router is started. It provides default values, but also allows you to
configure threshold values for the maximum physical up-time, the
maximum outgoing calls and the maximum charge units allowed on
each interface of an ISDN-Controller.
The default values are as follows:
Maximum Physical Up-Time: 40 min
Maximum Outgoing Calls: 200
Maximum Charge Units: 200
They were calculated according to the new tariffs of Deutsche
Telekom AG (as of January 1996):
Maximum amount of money allowed on
each interface per day: DM 24
Meter clock pulse Fernzone/Region 20
between 9 a.m. and 12 a.m.: appr. 12 sec
One charge unit costs: DM 0.12
--> Maximum Charge Units = DM 24 : DM 0.12 = 200
--> Maximum Physical Up-Time = (DM 24 : DM 0.12) x 12 sec = 2400 sec =
40 min
As soon as the threshold value for an interface is reached, an alert is
generated 3 times in 1-minute intervals, printed on the system con-
sole and sent via Trap. After that, the respective interface is automati-
cally barred; i.e., all connections set up over this interface are cleared,
no outgoing calls can be established over it and incoming calls on the
ISDN-Controller are rejected if addressed to this interface until the
administrator removes this bar. If the barred interface is a member of
an Interface Group, all other interfaces of this group are barred as
well to avoid that outgoing calls are simply performed over a differ-
ent interface.
To remove a bar, do one of the following:
