Scope and References clauses
Delete the clauses "Scope", "References" from ITU-T Recommendations Q.765.1 and Q.699.1 and replace with the
following two clauses (Scope and Normative references):
Scope
The present document describes the extensions required for the support of Virtual Private Network (VPN) applications
over the public Network Node Interface (NNI). This application makes use of the Application Transport Mechanism
(APM) described in EN 301 069-1 for bearer related signalling, and the Transaction Capability (TC) for signalling
involving no bearer. The present document specifies the respective users (i.e. APM-user, TC-user) to support the PSS1
information flows continuity in VPN applications (Transparent transfer of PSS1 information flows between PINX
entities). The public NNI provides transparency to the services of the private network.
The private network functionality is defined by ISO in its series of standards for Private Integrated Services Network
(PISN). In addition, the concept of a "Relay node" is introduced by the present document.
The present document provides for a number of network options. These are summarized in table 1.
Table 1: Network options
Option Values Remarks
Support of GFP functionality at transit Full support
PINX nodes
(subclause 6.2.5) Partial support Not applicable in the international
network (note 1)
Support of GFP functionality at gateway Full support
PINX nodes
(subclause 6.2.6) No support (note 1)
Continuation of calls with no application Supported (note 2)
association
(subclause 6.2.6) Not supported (note 3)
Relocation of gateway function Supported
(subclause 6.2.6) Not supported
NOTE 1:  Use of these options might result in certain private network supplementary services behaving
in an unexpected manner or not working at all.
NOTE 2:  In this case VPN calls has to be routed using a mechanism which can correctly route the call to
the terminating access without use of the VPN procedures specified in the present document.
NOTE 3:  In this case, it is required that the VPN procedures are only used on calls which are routed to
addresses which are known to support the VPN application via signalling which supports the
APM, otherwise the call will be released.
In addition, this EN describes the interworking between Signalling System Number 7 (ISDN) and extended DSS1 for
the support of VPN applications with PSS1 information flows. For the interworking in this EN related to ISUP, these
replace that specified in ETS 300 899 whereas all other interworking of PSS1 information flows is according to that
specified in ETS 300 899.
The interworking described here provides a sub-set of all possible interworking scenarios and is therefore intended to
describe only the relevant mapping of information flows between the two interfaces being described.
