[N]
. (See "Con-

●
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

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.

To configure a CUG, press
[E]
and, when prompted, enter:
●

CUG number:

●
any other requested information. (See Table 8-1.)
