  18. Voice Trunking – the Need • The existing infrastructure has no bandwidth left for expansion: • Saturated SDH network • Fixed wireless • Single access line, such as xDSL • Reducing the required bandwidth bring direct savings: • Inter-city leased lines • International Private Lines • Satellite Connectivity

  19. Voice Trunking – Present the Case • Understand the requirements • Retrieve info regarding cost of bandwidth (IPLC, Satellite, etc.) • Punch in the numbers • Let’s look at an example: • IPLC costs $4,000 a month • Compression ratio 10:1 • Each month $36,000 are saved • Payback  Less than 2 months

  20.
