  3. BTS BTS BTS BTS BTS BTS BTS BTS GSM Abis Optimization - Intro • Cost reduction by 2G Abis bandwidth optimization by 50% and more thanks to enhanced silence suppression and data compression Interface: E(PCM) A(PCM) / Ater Abis Solution: Vmux-2120 / Gmux Vmux-2120 / Gmux / Vmux-4x5 Vmux-4x5 BSC BTS PSTN MSC BSC MSC BSC

  4. Cellular Optimization Market Needs Market Background: • 1 Billion potential cellular subscribers in the GSM rural areas • Cellular backhaul relies on leased lines, private networks and satellite connections • Backhaul costs reach 40-60% of the operators’ OpEx • 2.5G / 3G services and mobile users’ increase generate additional network investments (Optimized 2G leased lines can be transferred to 3G networks) -> Connectivity optimization seriously impacts costs reduction.

  5. GSM Abis Optimization Where Does it Apply ? • GSM operators with expensive leased lines / satellite lines(> $500 / month / E1) • GSM operators with a lack of bandwidth • Due to lack of GSM infrastructure or • Due to 3G service penetration

  6. Point-to-Multipoint Remote Site BTS Value Proposition • Cost reduction of 2G Abis bandwidth reduction by 50% and more thanks to enhanced silence suppression and data compression Vmux-405 ETH / E1 E1 Central Office Vmux-445 BSC MSC Large Remote Site E1s E1s BTS Vmux-425 ETH / E1 E1 A-BIS

  7. Satellite Connections • Business Objectives: • Connectivity of GSM BTS over satellite (Abis Optimization) • Winning Combinations: • ABIS Optimization 1:3 • Cost effective Remote Site CentralSite Vmux-405 BSC E1 MSC E1 Vmux-425 E1s BTS RemoteSite Vmux-405 E1 BTS

  10. Abis Optimization – Features • Up to 3:1 average GSM Abis optimization for E1 traffic over E1 or ETH uplink • DTX independent –optimization in non-DTX mode • Improved optimization –Smart Packet Drop of non essential voice frames w/o affecting the voice quality and MOS • Data Optimization adds ~5%-10% bandwidth savings • High precision clock recovery over ETH uplink (no GPS required) • Dynamic EDGE • Auto timeslot detection for all cellular vendors • Reduced end to end delay for data (25 ms) • QoS- Signaling, voice and data separation at the uplink – each one could be assigned to a different priority queue • FR, EFR, HR, AMR, HR-AMR codec support
