The physical PINX at the originating interface shall include the VPN indicator information element in the SETUP message.
If the VPN indicator information element does not contain a CN identifier and a CN identifier is registered as a default for the access, then the default CN identifier shall be used.
If the VPN indicator information element does not contain a CN identifier and there is no CN identifier registered as a default for the access, then the call shall be rejected with cause No. 50, Requested facility not subscribed.
If the VPN indicator information element contains a CN indicator value and/or a CN identifier which is not associated with the access, then the call shall be rejected with cause No. 50, Requested facility not subscribed.
The physical PINX at the originating interface shall include the Called party number information element in the SETUP message.
If received from the physical PINX at the originating interface, the Calling party number information element and the Calling party subaddress information element shall be handled as follows:
– a Transit PINX shall transfer the information elements to the subsequent PINX regardless of any supplementary service subscription information;
– a Relay Node shall transfer the information elements to the subsequent PINX regardless of any supplementary service subscription information;
– an Outgoing Gateway PINX may transfer the information to the other network;
NOTE – The handling of numbers, e.g. translations, presentation indications, is outside the scope of this Annex.
– a Terminating PINX may transfer the information to the called user, depending on any restrictions (e.g. interface type or service).
The physical PINX at the originating interface may include the Transit counter information element in the SETUP message. Whilst the handling by the public network is outside the scope of this Recommendation, it shall be transferred as follows:
– a Transit PINX shall transfer the information element to the subsequent PINX;
– a Relay Node shall transfer the information element to the subsequent PINX;
– an Outgoing Gateway PINX may transfer the information to the other network.
