Reduce Costs for Signaling Monitoring and Billing Traffic

Reduce Costs for Signaling Monitoring and Billing Traffic

Your Needs
Reduce mobile backhaul costs for signaling monitoring and billing traffic, by grooming multiple E1/T1 lines and reducing the number of transport links.

Our Solution
RAD’s DXC modular multiservice access nodes reduce mobile backhaul expenses in 2G/3G networks, by efficiently transmitting signaling monitoring and billing traffic. The DXC units collect signaling timeslots from multiple cell-sites and groom them into E1/T1, E3/T3 or STM-1 trunks, fully utilizing the expensive leased lines connecting to the central protocol analyzers. In this manner, operators can reduce the number of overall network links and save on transport costs.

Benefits

• Provide complete access solution over SDH/SONET, with central management supporting voice and broadband data
• Optimize transport efficiency with cross connect, grooming and broadcast functionalities
• Enhance flexibility with modular design
• Increase service up-time through system redundancy

Reduce Costs for Inter-MSC Traffic

Reduce Costs for Inter-MSC Traffic

Your Needs
Reduce huge outlays in leased line circuits for long-distance inter-MSC connectivity

Our Solution
Inter-MSC (E channel) trunking is one of the main contributors to the cost of running a cellular operation. Typically, hundreds of long haul links are used to transport traffic between voice switches, in meshed, star or mixed network topologies. Reducing the number of links translates into immediate cost savings, adding directly to the mobile operator’s bottom line. Because the payload of inter-MSC transmission is voice traffic, the simplest and easiest way to realize this reduction is by compressing the amount of voice traversing the network using standard voice compression algorithms.

RAD’s Vmux/Gmux voice trunking gateways use standardized voice processing technology to compress a full E1/T1 circuit down to 128 kbps, or 16 full E1/T1 lines and associated signaling down to a single E1/T1 circuit over TDM or IP/Ethernet links.

Benefits

• Increase bandwidth utilization through up to 16:1voice compression
• Promote OpEx savings by reducing the number of required leased lines
• Support and optimize all types of signaling channels
• Enable transparent traffic delivery over packet with pseudowire encapsulation
• Small, scalable and easy to install
• Future-ready to support softswitch-based, NG mobile core
