18 Global Dialing Scheme

19 GDS  A structure for peering between gatekeepers, such that any endpoint associated with a ViDeNet zone may dial an endpoint in any other ViDeNet zone  ViDeNet Version 3 Dial Plan  A numbering plan for global video and voice over IP

20 GDS Number Scheme  Each number has four parts International Access Code (IAC) (also called the world gatekeeper prefix)- defined as 00 A Country Code (CC)- follows the ITU international access code system (1 for the US An Organizational Prefix (OP)- ViDeNet assigned them; some countries use area code/exchange prefix An Endpoint Number (EN)- a unique number (sometimes called H.323 extension) assigned to each endpoint by each organization (could be a E164 number or any other unique number)  IAC CC OP EN

21 GDS at Northwestern  The IAC is “00”  For the EN, we use a “1” followed by the last five digits of your telephone number  If you have more than one Video station and only one telephone number, follow the six digits by an integer  Northwestern was assigned 1169 as a organizational prefix  The number of my telephone on my desk at Northwestern is and the GDS dial number of my Viewstation is thus: (spaces for readability only)  Northwestern users registered with the Northwestern gatekeeper can use a short cut and dial each other using only the EN ( for me)
