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.
