/* Q.765.5 amd 1
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 .
