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

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

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 integerNorthwestern was assigned 1169 as a organizational

prefixThe number of my telephone on my desk at

Northwestern is 847 467 6885 and the GDS dial number of my Viewstation is thus:

00 1 1169 176885 (spaces for readability only)

Northwestern users registered with the Northwestern gatekeeper can use a short cut and dial each other using only the EN (176885 for me)
