Product Overview
RIC‐155L is a convertor that bridges between Gigabit Ethernet networks and STM‐1/OC‐3c networks, providing simple, efficient, and cost‐effective Gigabit Ethernet connectivity over SDH/SONET. The unit offers a migration path for connecting future‐ready IP devices to existing SDH/SONET networks. The device enables cost‐effective deployment of the SDH/SONET infrastructure for internet access and LAN connectivity. RIC‐155L supports e0ncapsulation using GFP per ITU‐T Rec. G.7041 or ANSI T1‐105.02, providing efficient bandwidth utilization. RIC‐155L can be managed for configuration, monitoring and diagnostics.
RIC‐155L features three Ethernet ports, a 10/100BaseT interface for management, and two interfaces for data transfer – one 100/1000BaseT data port with an RJ‐45 connector, the other a 100/1000BaseFX data port with standard SFP‐based connectivity. Connectors are STM‐1/OC‐3c SFP fiber optic.
RIC‐155L supports Quality of Service (QoS) with classification according to VLAN priority (802.1p). Classificati*** results are mapped into four tran***it priority queues with strict priority.
In order to increase service up‐time, RIC‐155L supports a fault propagation mechani*** to trigger the redundancy path mechani***s of the Ethernet traffic in case of SDH/SONET path failure.
RICi‐155L supports remote and local loopbacks on the SDH/SONET, and Gigabit Ethernet ports are used for physical port troubleshooting. Remote loopbacks can be closed on the SDH/SONET port, while local loopbacks are closed on the Gigabit Ethernet port. RIC‐155L can be configured to tran***it RDI and AIS indicati*** to the ADM equipment connected to the SDH/SONET port.
Setup, monitoring, and diagnostics can be performed via RAD’s Web‐based management application, which enables remote device configuration and maintenance. It is embedded into RIC‐155L and provided at no extra cost. This application can be run from any standard Web browser. Units can be managed locally, out‐of‐band or inband.
