  1. Lowering Backhaul Cost in Mobile Networks Using LA-130 Presented by: Asaf Wachtel Product Line Manager

  2. Introduction

  3. The Backhaul Challenge Source: T-Mobile Source: Heavy Reading • Revenue per bit dropping off a cliff • Value (to end users) of apps not related to data volumes • If the operators can’t substantially reduce their cost per bit, their margins will be hurt HSPA 450 times higher than GSM

  4. The drive to use Ethernet/DSL • The future of the cellular transport is without a doubt Packet-based (IP/Ethernet) • Ethernet based services (e.g. DSL) are always cheaper than E1 and provide greater bandwidth scalability Last Mile (Cell to Hub) Metro (Hub to RNC)

  5. Mobile Backhaul Solutions

  6. 2G/3G/xG Cellular Backhaul over ATM/SDH/SONET/PDH DSLAM LA-130 n x E1 TDM/ATM 2G BSC n x SHDSL 63  E1/T1 DSL Cell Site Gateway BTS/Node B Aggregation Site Gateway C.STM-1/OC-3c Cell Site Gateway ATM/SDH/ SONET Network STM-1/OC-3c n x E1/T1 TDM/IMA m x E1/T1 STM-1/OC-3c 3G RNC ACE-34xx/ACE-3600 ACE-3100/ACE-3200 BTS/Node B STM-1/OC-3c Node B Ethernet • Aggregation of multiple generation of mobile traffic over the same transport • Flexible configuration of any service any port • Reduce backhaul costs • Opex by statistical traffic multiplexing • Capex by using lower cost STM-/OC-3 ports in the transport network • Leverage DSLAM infrastructure

  7. Cellular Backhaul Migration to Packet Transport IP DSLAM GbE DSL Cell Site Gateway BSC n x E1 TDM/ATM n x SHDSL 63  E1/T1 LA-130 Aggregation Site Gateway BTS/Node B C.STM-1/OC-3c PSN Ethernet/IP/ MPLS Cell Site Gateway GbE n x E1/T1 TDM/IMA RNC FE ACE-34xx/ACE-3600 ACE-3100/ACE-3200 BTS/Node B STM-1/OC-3c STM-1/OC-3c Node B Node B Ethernet • Reduce transport cost leveraging NG packet transport (DSL and fiber) • Single access platform for multiple-generation traffic • Timing and synchronization over the packet transport network • Well suited for Fixed and Mobile Convergence (FMC)

  8. LA-130 Features

  9. LA-130 What makes the LA-130, the ultimate DSL Cell Site Gateway ? • Physical configuration • Traffic Shaping • Diagnostics & Management • Market Experience • Future Proof

  10. Physical Configuration • WAN interfaces • SHDSL 4 pairs Up to 4 Ethernet ports • Unique dimensioning, ideal for cellular backhaul: • Almost no other DSL CPE has E1 ports over bonded SHDSL • Almost no other DSL CPE has ATM IMA over bonded SHDSL • NO DSL CPE on the market has 4 E1s (UNI/IMA/CES) over bonded SHDSL • 4 E1 (ASAP) • 4 ATM UNI or ATM IMA or CES

  11. Traffic Shaping • Full support of ATM XC for UNI/IMA • Traffic shaping & classification per VC • Traffic scheduling according to CBR, VBR, UBR+ and UBR • Optimized CDVT • PW QoS support via VLAN tags or MPLS EXP

  12. Diagnostics & Management • ATM OAM as per I.610 F5 • Statistics Collection: • SHDSL • ATM • ETH • Out of band management via ETH port or RS-232 • In band management via dedicated VCC • Remote management via Telnet, Web browser, SNMP or RADview-EMS • Remote software/configuration upload/download

  13. Market Experience • RAD has 26 years experience in providing access solutions • RAD has 10 years experience in each of the following: • ATM Access • DSL CPEs • Pseudowire • RAD’s DSL CPEs installed successfully with leading carriers all over the world • RAD’s DSL CPEs have proven interoperability with all major DSLAM vendors

  14. Future Proof • Clear trend today of DSL infrastructure migrating to IP DSLAMs • Clear trend today of cellular backhaul migrating to packet-switched networks • LA-130 supports both TDM & ATM PW for 2G & 3G backhaul over PSN • LA-130 supports CESoPSN, SAToP & ATMoPSN standards • Same device provides cellular backhaul over ATM today and over PSN tomorrow • Advanced clock recovery support for running 2G and/or 3G traffic over PSN

  15. LA 130- Road map

  16. Summary • Reduce mobile backhaul costs via low cost DSL-based transport • Leverage existing DSLAM infrastructure • Future proof solution supporting both ATM & PSN including clock recovery • Ultimate combination of RAD’s market leadership in ATM, DSL & PW markets • Field proven solution • Unique Product in the Market
