Dedicated ATM Integrated Access Device

RAD’s LA-110 integrated access device delivers multiple services such as voice, Ethernet and Internet access over low-cost xDSL and ATM transport. Leveraging well-established deployments of wholesale SHDSL and ADSL services, it offers cost and coverage benefits for SMEs (small and medium enterprises) and in cellular backhaul. By extending end-to-end management up to the customer premises, the LA-110 enables service differentiation and QoS guarantees. Furthermore, the LA-110 integrated access device allows bandwidth capacity increase up to 9.2 Mbps, with IMA bonding over four SHDSL pairs.

• Reduces CapEx by leveraging widespread deployments of low cost DSLAM infrastructure

• Lowers OpEx by supporting intrinsic ATM QoS and OAM

• Provides leased-line type services at a fraction of the cost of leased E1/ T1 lines

• Supports 2G/3G colocation in cellular backhaul

• Simplifies installation with plug and play design

Enterprises requiring large capacity at headquarters can benefit from a network that combines a lower speed DSL service at branch offices and higher speed ATM at the main office. Supporting AAL1 constant bit rate (CBR) traffic, the LA-110 guarantees reserved bandwidth and minimum delay for mission-critical and real-time applications. This enables delivery of TDM services at a fraction of the cost of leased lines, while maintaining the same quality of service (QoS).

In addition to allowing transparent delivery of serial data streams and circuit-emulated services (CES) over ATM (AAL1), LA-110’s UNI network interface incorporates additional ATM adaptation layers. These include AAL2, supporting ATM loop emulation services (LES) for PSTN and ISDN BRI/PRI access, as well as AAL5, for Frame Relay, Ethernet and IP packet traffic.
