While the telecom industry transitions to new packet technologies, existing PDH and SDH/SONET infrastructure continues to play a significant role in linking end-point devices to central offices and NOCs (network operations centers). Without appropriate backhaul equipment that can offer cross-generation support for IP DSLAMs, telecom providers could face rollout delays for NGN business services and broadband DSL access in residential areas, putting a strain on their profitability.
RAD’s RICi demarcation devices enable operators to cost effectively reduce their time-to-market for new service offerings by leveraging widely available TDM networks. As shown in Figure 1, incumbent carriers can re-use their TDM installed base to offer new services, while service providers with packet cores can reach out-of-footprint customers over leased legacy lines by deploying the RICi-16 in point-to-point topology at the IP DSLAM POP (point of presence) and the central office. This allows them to transparently deliver Ethernet traffic over clear-channel E3 or T3 links and SDH/SONET backbones, with a seamless hand-off to the packet network. The RICi NTUs (network termination units) also work opposite the Egate-100 aggregation device, encapsulating IP DSLAM traffic over bonded E1/T1 circuits with bundled access rates of up to 32 Mbps. Employing standard Ethernet over NG-PDH protocols, the RICi demarcation devices increase bandwidth capacity by reducing latency and optimizing line utilization and throughput.
