7. Client/Server interface imond
Got everything?
Using the command “route”, the LC routing can be enabled or disabled. If a positive circuit
index is specified (1. . . N) the default route is changed to the circuit specified. If the index is
0, LC routing will be activated again and the active circuit is chosen automatically.
7.1.2. Annotations to the calculation of the online changes
The whole model how the online charges are calculated will only work correctly, if the charge
interval for a single circuit (variable ISDN_CIRC_x_CHARGEINT) remains constant throughout the
whole week.
Normally, this is correct for most of the internet providers. But if you dial in, e.g. to your
companies network, using the (German) Telecom (not the internet provider T-Online), the
change interval changes at 18:00 from 90 seconds to 4 minutes (information from June 2000).
Because of that, the definition
ISDN_CIRC_3_CHARGEINT='90'
ISDN_CIRC_3_TIMES='Mo-Fr:09-18:0.08:N Mo-Fr:18-09:0.03:N Sa-Su:00-24:0.03:N'
is not absolutely correct. After 18:00 the price is converted to 3 cents (4 minutes cost 12
cents), but the charge interval is wrong. Because of that, the displayed charge could differ
from the actual one.
Here is a tip, how different charge intervals can be handled correctly, anyhow (also important
for ISDN_CIRC_x_CHARGEINT): Just define 2 cicuits – one for each charge interval. Of course you
will have to adjust ISDN_CIRC_x_TIMES so that the valid circuit is always dialed, depending on
the charge interval.
Once again: If you connect to an ISP you most likely will not have this problem, because
the charge interval is constant all the time and only the prices per minute change (or doesn’t
it? I guess the German provider T-* could even introduce such a price model :-).
7.2. Windows-Client imonc.exe
7.2.1. Introduction
imond on the router and on the client imonc as a team have two use modes: the user and the
admin mode. In admin mode, all controls are enabled. In user mode the variables IMOND_ENABLE
(Page 71), IMOND_DIAL (Page 71), IMOND_ROUTE (Page 71) and IMOND_REBOOT (Page 71) control
if the respective functions are available. If all of these variables are set to ‘no ’, this means that
all buttons in the overview page are disabled except for the exit and the admin mode button.
The decision whether the user or admin mode is used, is based on the transmitted password.
By clicking the button admin mode, located in the status bar, you may switch to the admin
mode at any time by entering the admin password. To switch back imonc must be restarted.
Once imonc is started an additional tray icon is displayed, which shows the connection status
of existing channels.
The colors mean:
Red : Offline
Yellow : A connection is in the process of being established
