Establishing a Callback with your ISDN PC Card
For the same cost saving reasons explained in Establishing a Callback with your Modem PC
Card, the ISDN card in the BLACK BOX ® Advanced Console Server can be configured to call-
back client machines after receiving dial in calls.
The steps to allow callback are divided into two parts. Part One is the configuration for the
BLACK BOX ® Advanced Console Server (BLACK BOX ® Advanced Console Server Setup) as
callback server. Part Two is the configuration of a Windows 2000 Professional computer as
callback client.
BLACK BOX ® Advanced Console Server setup (Callback Server)
Step 1: Change the parameters in /etc/pcmcia/isdn.opts to fit your environment.
Step 2: Set the callback number in DIALOUT_REMOTENUMBER:
DIALOUT_REMOTENUMBER="8358662" # Remote phone that you want to
# dial to
Step 3: If your isdn line supports caller id, it is recommended that you also configure the
DIALIN_REMOTENUMBER and enable secure calls. Otherwise skip to step 4.
DIALIN_REMOTENUMBER="8358662" # Remote phone from which you will
# receive calls
SECURE="on" # "on" = incoming calls accepted only if remote
# phone matches DIALIN_REMOTENUMBER; "off" =
# accepts calls from any phone. "on" will work
# only if your line has the caller id info.
