2. Outline • Pseudowire/TDMoIP Concept • Market Overview, Customers and trends • Applications and benefits • Product Offering

3. Pseudowire/TDMoIP Concept

4. What is TDM PWE / TDMoIP? • Protocol for extending TDM circuits over PSN: IP, Ethernet or MPLS • Terminology • TDMoIP • Circuit Emulation(CE) • Pseudowire (PWE) • PWE provides: • Transparency to signaling protocols (CAS, PRI, SS7…) • Ideal for voice, video & data applications • Investment Protection – migration to PSN without compromising rich legacy features

5. RAD’s TDM Pseudowire Solution • Preserves investment in legacy equipment in migration to PSN • Carrier-grade TDM voice or data over packet networks • Low latency but no compression • Maintains clock synchronization • Lowers OpEx of TDM service by utilizing packet infrastructure POP/HUB/CO PWE Gateway Packet Network PE PE PWE Gateway TDM Service TDM Service Last Mile Pseudowire Tunnel

6. Market Overview

7. Target Customers • Enterprises, government and public institutes • Preserving investment in legacy TDM equipment • Reducing monthly transport cost • Carriers • Alternative carriers can increase revenue by selling TDM services • Incumbents can reduce OpEx – one transport network

8. Market Trends • Growing availability of PSN with QoS and traffic engineering in the WAN • Growing fiber deployment to the Business (xPON) • Incumbents are pressed to reduce OpEx and evaluating TDM PW • Standardization • RAD is considered as market leader in TDM PW with good products (70% of the market) Over 110,000 RAD TDMoverIPports installed since 2000 Over 50,000 RAD TDMoverIPports installed in the last two years only

9. Applications

10. Legacy Leased Lines over any Packet Access Technology Serial PBX Target Customers: • Alternative Carriers and Cables MSOs • Enterprises and public institutes looking to save on leased line costs • Incumbents in migration or out of their network reach Fixed Wireless IPmux-2L n x E1/T1 ETH PBX IPmux-216 n x E1/T1 GbE/FE over Fiber (Pt-2-Pt, xPON) ETH PBX Gmux-2000 Ethernet over Cable IPmux-24 ETH/IP/MPLS Core Network n x E1/T1 GbE Cable HFC Infrastructure ETH n x E1/T1 or Ch.T3 or Ch.STM-1/OC-3 PBX IPmux-24 n x E1/T1 FE / GbE xDSL ETH PSTN PBX LA-110 n x E1/T1 SHDSL ETH

11. Business Case – USA 12/2008 “Speakeasy Provides Cost Savings for Small Businesses, Cutting Ethernet Broadband Prices and Doubling T1 Speed” • Price for 2 x T1 leased lines (3 Mbps): $760 per month • Price for 3 Mbps Ethernet bandwidth: $380 per month • ROI for IPmux-24/FE/2T1: $1815/$380 = 4.7 months Note: The cost of E1/T1 leased line is proportional to the distance and can be higher than what is mentioned above

12. Benefits and RAD’s Advantages Customer Benefits • For the enterprise end user • Preserving investment in legacy TDM equipment • Reducing transport cost • For the carrier end user • Alternative carriers can increase revenue by selling TDM services • Reducing OpEx – one transport network • Standards based • TDM over packet using any access method RAD Advantages • Long term experience in TDM pseudowire – since 1999 • Variety of emulated services and interfaces: E1/T1, serial (V.35/X.21), analog voice • Comprehensive pseudowire functionality • Most advanced synchronization capabilities • Full solution: remote and aggregation devices
