MAX 6000/3000 Network Configuration Guide
Configuring X.25
Configuring X.25 IP connections
Configuring X.25 IP connections
This section describes how to configure the MAX to exchange IP datagrams over the X.25 
network connection specified in an X.25 profile. X.25 IP connections must be routed. They 
cannot be bridged. 
You must first set Ethernet > Answer > Encaps...> X25/IP=Yes, and Ethernet > Connection > 
Connection profile > Encaps=X25/IP. The Encaps parameter specifies the encapsulation 
method to use when exchanging data with a remote network. Both sides of the link must use 
the same encapsulation for the connection to be established. 
Then you can configure the related parameters located in Ethernet > Connection > Connection 
profile >
 Encaps Options. These parameters define a X.25 profile name, a logical channel 
number, an encapsulation type for calling the remote site, whether the call packet should have 
a reverse charge element, and a network id:
Parameter
Specifies
X.25 Prof
A 15-character text field containing the name of an X.25 profile that 
the MAX uses for the logical connection. If the specified X.25 profile 
cannot be found, the MAX does not start a session for this Connection 
profile. As a safeguard against such misconfiguration, an active 
Connection profile specifying X.25 encapsulation cannot be saved 
unless you define the named X.25 profile and make it active.
LCN
The logical channel number (LCN) to use in the case of a Permanent 
Virtual Circuit (PVC). The default of 0 (zero) specifies that the MAX 
does not provide a logical channel number, so the connection is not a 
PVC.
Encaps Type
Which encapsulation to use when calling the remote site. When 
receiving a call, the MAX accepts any of the three types of 
encapsulation. The default is RFC 877.
Reverse Charge
Whether or not the call packet should include an X.25 reverse charge 
request facility element. The default is No.
RPOA
The set of Recognized Private Operating Agency (RPOA) user 
facilities to use in the next call request. The RPOA facilities provide 
the data network identification code for the requested initial RPOA 
transit network. You can specify up to four digits. The default is null.
CUG Index
The Closed User Group (CUG) index facility to use in the next call 
request. The CUG index facility specifies, for the called switch, the 
closed user group selected for a virtual call. You can specify up to two 
digits. The default is null.
NUI
A name/password combination that gives you access to a commercial 
packet-switched network. The set of Network User Identification 
(NUI) related facilities to use in the next call request. NUI provides 
information to the network for billing, security, network management 
purposes, and activation of subscribed facilities. You can specify the 
NUI, consisting of up to six digits, to use in the next call request. The 
default is null.
