Product SummaryRAD's LA-110 integrated access device collects voice, data and LAN traffic from multiple sites and aggregates these services towards the ATM transport network over existing DSL infrastructure. Further, the LA-110 integrated access device employs pseudowire emulation, enabling carriers to provide high revenue leased line and cellular backhaul services over IP DSLAMs and packet switched networks. As an option the LA-110 can support four SHDSL pairs based on IMA bonding, providing data rates up to 9.2 Mbps at distances of up to 8 kilometers (5 miles). The LA-110 integrated access device guarantees Quality of Service (QoS) and end-to-end management up to the customer premises. By employing the LA-110 integrated access device, net utilization can be greatly improved without investing in new infrastructure. Benefits• Provides leased-line services at a fraction of the cost of leased E1/ T1 lines • Pseudowire emulation enables carriers to provide high revenue leased line and cellular backhaul services over IP DSLAMs and PSN • Delivers ATM QoS to customers • Plug and play installation and configuration simplifies installation Further Product InformationThe mobile evolution to 3G will introduce a new range of bandwidth-hungry mobile services. To succeed in this demanding environment, mobile operators face the challenge of utilizing the most efficient backhaul technology that will yield the most cost-effective solutions. This is particularly valid today, when 3G services are starting to ramp up, and network expansions are required in order to support the increased capacity. ATM has been defined by the 3GPP (3rd Generation Partnership Project) as the preferred backhaul technology, due to its ability to assure QoS and to provide service differentiation between delay-sensitive (for example, voice and real-time video) and non-delay-sensitive (for example, Internet access and video streaming) traffic. Reduce cellular backhaul expenses through aggregation and use of DSL infrastructureTraffic aggregation reduces both Capex and Opex, due to the reduction of the number of links in the network and the ability to use lower priced, DSL-based ports in the network. The LA-110 integrated access device is specifically designed to accommodate the rapid expansion in mobile backhaul traffic resulting from the widespread deployment of 3G services. The devices aggregate E1 lines in the DSL uplink to ensure the most economical allocation of backhauling resources and the delivery of multiple 3G services. RAD's Link Access (LA) family of integrated access device enable carriers to converge multiple services, such as voice, LAN and data, to small and medium-sized enterprises (SMEs) over a DSL access line, using the existing ATM or packet-based network and DSLAMs. This improves network utilization and eliminates the need to invest in new infrastructure, thereby achieving increased profitability. The integrated access device guarantee Quality of Service (QoS) and end-to-end management up to the customer premises. Leased lines over ATM (LLoATM)Employing AAL1 constant bit rate (CBR) traffic enables the IADs to support QoS with reliability for mission-critical applications, end-to-end across the network. This provides leased line services at a fraction of the cost of leasing E1/T1 lines. E1/T1 or serial data interfaces support any type of user interface and guarantee the same Quality of Service as TDM-based leased line services. Enterprises requiring fat pipes at headquarters can build a network combining lower speed DSL at branch offices and higher speed ATM service at the main office using ATM NTUs (such as RAD's ACE ATM access units). With support for structured data, the carriers can build a network with smooth migration from SDH to ATM backbones. IMA BondingAs an option the LA-110 integrated access device can support IMA (Inverse Multiplexing over ATM) over 4 × 2-wire SHDSL. This option provides up to 9.2 Mbps, filling the gap between lower speed DSL and the higher speeds provided by fibre networks. Transmission distance is up to 8 kilometers (5 miles). The IMA option provides solutions for a wide range of applications, from SMEs requiring high speed access to cellular providers wanting to backhaul 2G and 3G transmissions over DSL lines. Pseudowire emulation (LLoPSN)The integrated access device can take TDM or ATM streams and convert them into packets for transmission over the new packet-switched networks (PSN). Using pseudo wire emulation enables carriers to provide high revenue leased line and cellular backhaul services over IP DSLAMs and PSN. Network management reduces expensesThe LA-110 integrated access device feature superior management capabilities through a local terminal, Webbased interface or remotely by using Telnet or SNMP. RADview SNMP management software supports large networks in a simplified way. Comprehensive diagnostics and statistics allow full control and monitoring of the units, resulting in reduced operational and maintenance costs. ATM Quality of Service ensures end-to-end controlLA integrated access device provide ATM QoS so the carrier can deliver all voice and data services with QoS guarantees. Traffic shaping per VC secures the priority of critical applications. Operation, administration and maintenance (OAM) cells provide complete end-to-end control of the network. They enable fault notification and performance and connectivity monitoring, including delay measurement. Easy installation and operation reduce operating expensesPlug-and-play units facilitate installation. Simple software and configuration upgrades enable the communications service to grow together with the customer's business, without the need for new hardware.
