Bandwidth Challenges Mobile and Wireline Operators’ Profits When:

Transmission bandwidth lags business growth

Bandwidth has high cost

Bandwidth has limited availability


Optimize Existing Network

Quick way to “add” capacity Utilizing the same bandwidth, optimization adds capacityCustomer satisfaction

• More bandwidth available per subscriber

• Ability to add subscribers with same bandwidth costs

OPEX reduction Consolidation and bandwidth optimization of traffic

CAPEX reduction As traffic grows, less CAPEX will be required


Dialogic’s Optimization Solutions – Available Benefits

Cost-effective and shortest-cycle solutions designed to minimize bandwidth and network resource requirements while preserving high voice quality

Saved bandwidth and network resources become available for capacity expansion and/or network architecture migration

Significant CAPEX and OPEX savings opportunities Smooth transition from 2G-based to 3G IP-based transport and network architectureSeamless expansion of 3G networksProvide a single, common transport solution for the different types of backhaul trafficUnique 1U fully redundant platform
