voice Slash Voice Transmission Costs over IP and TDM Networks Compressed Voice System Vmux Product Family Innovative Access Solutions

VS Compressed Voice over IP and TDM Networks In today s competitive telecommunications environment, extending capital budgets and lowering operating costs are often the keys to survival. RAD s Compressed Voice System (CVS) utilizes existing resources more efficiently slashing recurring E1/T1 costs by providing a high-density voice compression system designed to work over both TDM and IP-based networks. CVS uses powerful voice processing algorithms to compress a full E1/T1 down to 128 kbps, or 16 full E1/T1 lines (496/384 concurrent voice channels) and associated signaling down to a single E1/T1 circuit. CVS lets carriers provide high quality voice services with a small initial investment and low operating costs. CVS is also ideal in multi-site enterprise networks, remote call centers and other voice trunking applications. Typical Users of Compressed Voice Solutions Mobile Operators: Inter-MSC trunking International Telecom Providers: Wholesale and calling card services Call Center Providers: Connecting offshore call centers Multi-Site Enterprises or Military: PBX and LAN extension over limited bandwidth infrastructure (satellite, wireless, etc.) Alternative Carriers: E1/T1 voice circuits over broadband connections National Carriers: Rural telephony services over satellite

Products Vmux Family of Compact Voice Trunking Gateways Minimizes Bandwidth Requirements Vmux-2100 The Vmux-2100 voice trunking gateway provides compressed voice transmission over both TDM and IP-based networks. Employing powerful voice compression algorithms as well as TDMoIP technology, the Vmux-2100 can compress up to 16 full E1/T1 circuits over a single E1/T1, serial or packet-based network. Vmux-110 The Vmux-110 remote site voice trunking gateway provides LAN and compressed voice transmission over both TDM and IP-based networks. Employing powerful voice compression algorithms as well as TDMoIP technology, the Vmux-110 can compress a full E1/T1, or four or eight analog lines, leaving more bandwidth for data transport. Vmux with 16:1 compression is the most cost-effective solution on the market Fast payback in 30 days to one year * * depending on your configuration and line costs Vmux-210 The Vmux-210 analog voice trunking gateway is a remote compressed voice channel bank, providing LAN and compressed voice transmission over both TDM and IP-based networks. Employing powerful voice compression algorithms as well as TDMoIP technology, the Vmux-210 can compress up to 30 analog lines, connected to phones or faxes, leaving more bandwidth for data transport. Gmux-2000 The Gmux-2000 central office voice trunking gateway is a carrier-grade platform for large voice compression applications (up to 112 E1s). It employs the same TDMoIP technology, compression algorithms and advanced voice functions as RAD s Vmux CVS products, and is fully interoperable with them.

Best Voice Compression on the Market RAD s Vmux voice trunking gateways achieve 16:1 compression by combining industry standard compression algorithms and silence suppression with RAD s unique TDMoIP aggregation and multiplexing protocol. The graph below shows how TDMoIP achieves up to 68% better bandwidth utilization than VoIP solutions. Bandwidth calculations assume G.723.1 compression at 5.3 kbps with 50% silence suppression. 700 624 600 562 500 499 437 400 374 VoIP VoIP = Wasted bandwidth Required bandwidth (kbps) 312 300 250 TDMoIP 187 200 195 178 161 125 131 114 98 100 81 62 64 42 47 25 31 0 1 4 6 12 18 24 30 36 42 48 54 60 Number of voice channels Main Benefits & Features of RAD s CVS solutions Reduces the amount of bandwidth required for voice transmission by up to 16:1, while maintaining toll quality, without affecting telephony features Silence suppression reduces bandwidth required to a minimum, when no calls are in process Seamless migration from today s TDM networks to tomorrow s IP networks Optimizes the bandwidth required for HDLC-based signaling Compact, scalable and simple to deploy

pplications PBX and LAN Extension over Limited Bandwidth Infrastructure Multi-site organizations, with branches shipping fleets, mining/construction/ located in remote locations with limited or broadcasting enterprises, and military no infrastructure at all, can use Vmux voice units, which can increase the capacity of trunking gateways to reduce the amount their limited WAN communications of bandwidth consumed on expensive infrastructure without having to replace satellite or microwave links. This type of existing equipment or retrain existing staff. solution is ideal for oil/gas platforms,

International Toll Bypass RAD s Vmux/Gmux voice trunking gateways significantly reduce the bandwidth required for international and national voice transmission, enabling it to be transmitted over IP or TDM networks. The solution maintains toll-quality voice and is completely transparent to special services provided by telephony switches. PRI Leased Line Replacement Alternative carriers and ISPs that already have their own IP networks with xdsl or cable access to the customer premises can now offer ISDN PRI (Prime Rate Interface) leased line services to businesses over limited bandwidth circuits at attractive low prices.

Applications Offshore Call Centers Offshore call centers with bulk voice trunking that no bandwidth is consumed during needs can reduce expenses on backhaul periods of silence, and no telephony by using voice compression and silence features are affected, makes this solution suppression to reduce bandwidth. The fact extremely attractive for call center providers. Inter-MSC Trunking Typically, hundreds of long haul links are technologies to significantly reduce the used to transport traffic between MSCs number of required leased lines. These (E-channel) in meshed, star or mixed savings translate into fast payback. The fact network topologies. Limiting the number that the same devices can work over both of links translates into immediate cost TDM and IP networks makes this solution savings. RAD s Vmux/Gmux voice trunking completely future proof. gateways use advanced voice compression
