• Interests include deploying scalable,
  standards-based digital video architecture and
  services for use in research and higher education
• Co-sponsors workshops and digital video projects
  with the Southeastern Universities Research
  Association, Internet2, the Coalition for
  Networked Information, and leading industry
  consortia

• 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 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)
