15. Check the setting for COSO .
COSO (Charge One Site Only) lets you define which site of an
ISDN connection is to assume the charges.
Default: Disabled
Options: Disabled, Local, Remote, No Dial-Out, Time Re-
stricted
When COSO is disabled, the site that established the (underly-
ing) physical connection assumes the charges.
When you set COSO to Local, your site assumes the total connec-
tion costs. In this case, your router identifies an incoming call
from this site by the number delivered on the D channel (CLI
number), rejects the call and calls back. This is why you must
enter the CLI number of this remote site in the CLI List (see Step
30).
When you set COSO to Remote, the following happens: Each
time your router has to transfer data to this remote site, it will
issue a call set-up request over the D channel. It expects that the
remote site rejects the call and calls back to assume the charges.
If the remote site does not reject the call on the D channel, the
connection is switched through on the B channel(s) and connec-
tion charges accrue for your site. In this case, COSO is automati-
cally changed to "No Dial-Out" and the connection is cleared. No
further charges accrue for your site.
When you set COSO to No Dial-Out, no call set-up request is
issued over the D channel. All kinds of outgoing calls to this
destination are barred.
Time-Restricted lets you define times and days at which you
want to change COSO automatically. For information on how to
configure time restrictions, refer to Step 29.
For an example for the use of COSO, refer to the Technical Note on
NetWare MultiProtocol Router for ISDN 3.1.
