154 NetWare MultiProtocol Router for ISDN 3.1 Installation and ISDN Configuration Guide
The Call Acceptance Database (SYS:ETC\ISDNCADB.CFG) contains
all remote sites and their numbers you want to allow access to your
router.
To perform this special ISDN security check, you have to set the
parameter "Call Acceptance" in the "Expert Configuration of ISDN
Interface <Name>" menu to "Only Registered Numbers" with the
desired option (see Chapter 6, "Configuring ISDN Interfaces").
To find out the CLI number and the caller specified number, have the
respective remote sites set up a connection to your router. The CLI
number, transmitted over the D channel, and the caller specified
number will be printed on the NetWare system console.
Perform the following steps to register authorized remote sites and
their numbers in the Call Acceptance Database:
1. From the Global MPR for ISDN Configuration menu, select
Call Acceptance Database and press <Enter>.
The Call Acceptance Database window appears. Initially, the
database is empty.
2. To add entries, press <Ins> to display an empty Registered
Number mask.
3. In the Registered Number field, enter the number of the
remote site you want to allow access.
4. Select the Registered Number Type.
Options are "Caller-Specified Number" and "CLI Number". Select
the type of number you entered before.
5. (Optional) Enter any comment (name or remark) that helps
you to identify the entry and to relate the number to the
corresponding remote site.
6. Quit the mask with <Esc>. You are asked if you want to make
a second entry for the remote site.
When you set "Only Registered Numbers: CLI and Caller
Specified" for Call Acceptance, you have to make two entries for
this destination: one containing the CLI number and one
