USRobotics NETServer/8 - Manual (Page 71)

Network Dial In Access 5-13
A modem group must be defined to tell the NETServer which
modems it can use to dial out to the location. Note that since
only serial port 4 was configured for dial out use, the group we
create will contain only port 14.
set s4 group 1
set location sales_1 group 1
Maxports (the maximum number of ports that can be used to
dial out to a location) must be set to something other than its
default (0).
set location sales_1 maxports 1
For a more in-depth discussion of location table entries, please
see Adding a remote device to the Location Table in Chapter 6.
Finishing the user table entry
Now that we have created the location, we can add the second
line of the user table entry. It looks like this:
set user userC dialback sales_1
Save your work and reset the ports
Use the following commands:
save all
reset s3
reset s4
