SVC or PVC Parameters The parameters for assigning either SVCs or PVCs are
described in the following paragraphs.
For SVCs
Remote X.25 address The remote X.25 Address is the remote node’s X.25 address. This
address is required for SVCs if you have specified an X.25 address key.
This address must be 15 digits or less.
Facility set The facility set name is a name for a set of X.25 connection parameters.
The parameters are determined by the type of X.25 network that you
are subscribed to. You can configure options in a facility set so that
specified options are available for every virtual circuit or negotiated for
each virtual circuit on a per-call basis. This facility set will be used
when a connection is made from your node to the specified remote node
or from the specified remote node to your node. A Facility Set is
required for SVCs if you have specified an X.25 Address Key. The
facility set name must be eight characters or less, and the first
character must be alphabetic. You can configure up to 128 facility sets.
To modify facility set parameters, enter a 5 in the field at the bottom of
the screen and press the
[Go To]
key. This will take you to the X.25 User
Facility Sets screen. From this screen you can create new or modify
existing user facility sets. Refer to the NS 3000/iX NMMGR Screens
Reference manual for more information.
Security Class The security class is the level of logical security you want to have when
a connection is made to or from the specified remote node. A Security
level is required for SVCs if you have specified an X.25 Address Key.
The possible values are as follows:
• IO—Both incoming and outgoing calls are accepted. This is the
default value.
• IN—Only incoming calls are accepted from this particular remote
address. Outgoing calls will be rejected.
• OU—Only outgoing calls are accepted to this particular remote
address. Incoming calls will be rejected.
• LK—Entry is locked. No call is accepted, either inbound or
outbound.
For PVCs
Permanent VC number The PVC number identifies a permanent virtual circuit (PVC) on
the remote node. If you have entered a name in the X.25 Address Key
field and are configuring PVCs, then you also have to enter a value for
the PVC number.
