4.1.13.2.1  RADIUS Packet Format  
Each packet description includes descriptions of every Attribute-Value pair for this packet type. Attributes 
may be either standard or vendor specific. If the attribute value is unknown for any reason (e. g. if the outgoing 
trunk  is  missing,  it  is  impossible  to  identify  the  CdPN_OUT  variable  value,  which is  used  as  a  value  for  some 
attributes), then the attribute is not included into the message. 
Standard attributes have the following description: 
Attribute name (attribute number): attribute value 
Vendor attributes: 
Attribute name (attribute number): vendor name (vendor number): VSA name (VSA number): VSA value 
where: 
Attribute name—always Vendor-Specific; 
Attribute number—always 26; 
Vendor name—name of the vendor; 
Vendor  number—the  vendor  number  assigned  by  IANA  in  the  PRIVATE  ENTERPRISE 
NUMBERS document (http://www.iana.org/assignments/enterprise-numbers); 
VSA name—vendor attribute name; 
VSA value—vendor attribute value.
