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.
Voice Trunking & VoIP for TS2009 Slide 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

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

Voice Trunking
The Vmux voice trunking family:
• Enables up to 16:1 compression of E1/T1, and analog lines
• Transmits the traffic over a single E1/T1, Serial, or IP link
