“Things Are Changing”
  • More people have used the Internet in its first 5 years, than people used telephones in the first 30 years of Telephony
  • A Nation the size of the United Kingdom Joins the Internet every six months
  • The Internet already carries more information than all the telephones in America

“I predict that in five years there will be no separate telephony and internet networks, but a single network -- to homes and businesses --which will support wireless, telephony, Internet access, and possibly cable…. There will be a single seamless IP network with more advanced security, that will support different quality of service level guarantees”

ports at each location call detail usage analysis
Ports at Each Location - Call Detail & Usage Analysis
  • Mid-size branches
    • Each user around 2.8 hours per day; 16 users makes 45 hours = 2688 minutes/day
    • (* 17% for busy hour load) = 457 minutes/busy hour = 7.616 Erlangs
    • (* 20% traffic to HQ) = 1.52 Erlangs to HQ. This equals four voice channels.
  • NYC and London
    • Each user three hours per day; 40 users makes 120 hours = 7200 minutes/day
    • (* 17% for busy hour load) = 1224 minutes/busy hour = 20.4 Erlangs
    • (* 20% traffic to HQ) = 4.08 Erlangs to HQ. This equals eight voice channels.
  • Corporate requirements
    • Total Erlangs = five branches at 1.52 + and two at 4.08 =15.76
    • Total number of lines needed at HQ is about 20 for .05 blocking probability
    • The voice compression module uses 8 kbps (CS-ACELP)
    • (Actually silence suppression reduces this to less than 8 Kbps so each 64 Kbps channel could support eight voice-channel trunks
