  2. General • Channelized Ethernet gateway for interconnecting packet networks via PDH/SDH/SONET access • Aggregates and switches Ethernet traffic to a single STM‑1/OC-3 port, or to three channelized T3 ports • Connects up to 84 remote LANs over E1/T1 or 60 bonded nxE1/T1 lines, or 126 remote LANs over fractional E1 or T1 lines

  3. Market Problem– Profitable Ethernet Services over SDH/SONET • Ethernet Services are relatively lower cost services • Native Ethernet does not reach all locations • SDH/PDH/SONET networks are widely available, and can be used to deliver carrier class Ethernet services • The challenge: • Carriers providing low cost Ethernet services over the available access networks, while maintaining profitability and generating new profits • Enterprises and Utilities can utilize the available SDH/SONET for new Ethernet based applications • Leasing low cost transmission from 3rd party in order to reach more customers - extend the reach of existing services

  4. Ethernet over PDH Provider’s Node Customer Premises RICi-E1/T1 E1/T1 Ethernet • Remote solution - Different RICi models provide solution ranging from single E1/T1 to nxE1/T1 • Centeral site solution – Egate terminating SDH into the PSN network • NxE1/T1 bonding based on MLPPP Customer Premises Egate-100 STM-1/OC-3 (APS) 3*DS3 RICi-4/8E1/T1 SDH/ SONET GbE PSN Eth/IP/MPLS N*E1/T1 Ethernet PSN Customer Premises RICi-E1/T1 Ethernet FE1/FT1 Customer Premises RICi-4/8E1/T1 N*E1/T1 Ethernet

  5. Main Value Preposition • Complete solution with RAD’s CLEs (RICi-nXE1/T1, FCD) • Reduces equipment costs compared to alternative solutions (Single box solution) • Reduces operation costs: • Flexible service provisioning: 64kbps to n*E1/T1 • One management system • Ethernet diagnostics and monitoring • Lower space (1U) and power requirements • VLAN stacking/stripping at customer Edge or provider Edge: • Ensures transparency to customer LAN settings • Secured separation of customer and management traffic • QoS based on user VLAN Priority (802.1p), DSCP and IP Precedence marking: • Enables differentiated services according to Ethernet or IP marking

  10. Remote Management Remote Site RICi-E1/T1 CPE • Using widely deployed SDH/SONET infrastructure to provide management services • Reduced OPEX by managing remote devices when in-band management is not available • Low cost, small footprint E1/T1 FE Headquarters Remote Site Egate-100 CH.STM-1/OC-3c (APS) or 3 x DS-3 RICi-E1/T1 CPE Service Network SDH/ SONET GbE E1/T1 FE PSN Remote Site Management Station RICi-E1/T1 CPE E1/T1 FE

  11. What's new in the product? Version 2.60

  12. Main Additional Features • GbE redundancy –link aggregation protocol 802.3ad • Support of up to 60 remote LANs over bonded n  E1/T1 lines-(previous versions supported up to 42) • Split Horizon • Management Features: • User defined access authorization • Management access control • SYSLOG (RFC 3164)

  13. GbE redundancy • Link Aggregation (802.3ad) compliant • Two GbE ports can be used as a single aggregated port upon configuration • The link aggregation standard provides inherent, automatic redundancy on point-to-point links. In case of a link fail, network traffic is dynamically redirected to flow across the second GbE link • The link aggregation adds robustness to the system • Connection is maintained and the data flow is not interrupted in spite of a single link fail

  14. Split horizon • Support DSLAM aggregation application for Internet services • Prevents local switching between remotes sites, to avoid network congestion • two operation modes: • Full: local switching between logical ports is disabled for all VLANs • Per VLAN: disable local switching for certain VLANs and allow local switching for other VLANs
