• VoIP – Standard SIP solutions

• Summary - Comparing Pseudowire, Compressed Voice and VoIP


Providing Voice Services in a mix,TDM and Packet World

• Continue Providing voice on the existing TDM networks

• Expensive CapEx and OpEx of TDM networks

• Separate access networks

• Some TDM equipment is becoming outdated / obsolete

• Some Alternatives:

• Voice on packet networks - TDM Pseudowires

• Compress TDM Voice traffic - Increase capacity, better utilization

• VoIP – Standard SIP Solutions

Agenda





• Summary – Comparing Pseudowire, Compressed Voice and VoIP


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


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


Inter MSC Compression

Suitable for:

• Cellular Operators

Benefits:

• Significant bandwidth reduction (up to 16:1) translates to significant cost savings

• Transparent to any type of signaling

• Seamless migration from TDM to IP networks

• Compact, scalable and simple to deploy
