Network ID
The coding of the Network ID field is identical to the coding of the Network ID field in the
Global Call Reference parameter as specified in clause 6/Q.1902.3 (see [3]).
NOTE .When used inside a network domain, the Network ID may be omitted by setting the
Network ID Length indicator to the value "0".
Q.1902.3
The following codes are used in the subfields of the global call reference parameter field:
a) Network ID
The Network ID contains the value field (coded according to ASN.1 BER) of an object
identifier identifying the network. This means that the tag and length fields are omitted.
An example of such an object identifier can be the following:
.{itu-t (0) administration (2) national regulatory authority (x) network (y)}
The value for x is the value of the national regulatory authority (one of the Data Country
Codes associated to the country as specified in ITU-T X.121 shall be used for "national
regulatory authority"), the value for y is under the control of the national regulatory
authority concerned.
b) Node ID
A binary number that uniquely identifies within the network the node which generates the
call reference.
c) Call Reference ID
A binary number used for the call reference of the call. This is generated by the node for
each call.
