general
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
market problem profitable ethernet services over sdh sonet
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

main value preposition
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

main additional features
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)
gbe redundancy
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
split horizon
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
