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.
