Configuring X.25 8-3
The third screen may be the last you need to configure for this port. At that screen:
●
If you want to configure one or more closed user groups, press [N] . (See " Con-
figuring Closed User Groups " below)
●
If this will be one end of a network trunk, press [O] . (See " Configuring a
Network Trunk " on page 8-4.)
●
If this port will be connected to a dial modem, press [P] . (See " Configuring a
Dial Port " on page 8-5.)
●
If none of the above applies, press [F3] twice to return to X.25 Port screen 1, then
perform the next desired operation.
You cannot configure a port to be both a Network trunk and a Dial port.
Configuring Closed User Groups
Closed User Group (CUG) is a privacy feature that allows creation of up to 100 groups
of users per port. Members of a CUG can communicate with other members, but
access to and from network users outside that CUG may be denied (determined by the
settings configured for
Outgoing Access Allowed and Incoming Access Allowed ). The
CUG index number is included in call packets, and is cross-referenced with the CUG
Index in the SmartSwitch 1800 software.
Figure 8-2 X.25 Port CUG Parameters
To configure a CUG, press [E] and, when prompted, enter:
●
CUG Index: 0-99 (the default is 0 ), which is simply a reference to the CUG.
●
CUG number: 1-16383 (the default is 1 ), that will be associated with the index.
●
any other requested information. (See Table 8-1 .)
To delete a CUG, press [F] and enter the index of the CUG to be deleted.
