Calculations; Traffic - Avaya 1000 Installation And Commissioning Manual

Branch Office engineering example
• Traffic Distribution:
- IP Deskphones with UNIStim firmware: forty-five per cent to other IP Deskphones with
UNIStim firmware (Intra-IP calls), fifty-five per cent to Branch Office TDM telephones and
TDM trunks.
- TDM telephones: forty per cent of calls to TDM trunks, sixty per cent of calls to IP
Deskphones with UNIStim firmware.
• No trunk traffic between Branch Office TDM resources and Main Office.
Conference traffic is usually not singled out for calculation in traffic engineering. When a Branch
Office does not have conference capability, conference call participants must use the LAN/WAN to
reach the Main Office to join conferences. However, if the traffic is significant (a rough guide is more
than 10 per cent of IP Phone traffic), include traffic in the LAN/WAN bandwidth calculation.
