RIC-155L Gigabit Ethernet over STM-1/OC-3 converter

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 RAD RIC-155L 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. The RAD RIC-155L supports encapsulation using GFP per ITU-T G.7041 or ANSI T1-105.02, providing efficient bandwidth utilization. RIC-155L can be managed for configuration, monitoring and diagnostics.

Typical applications include enabling IP DSLAM, IP Node B and WiMAX BTS backhauling (Figure 1), and connecting point-to-point Ethernet Private Line over SDH/SONET (Figure 2).

The RAD RIC-155L supports frame size of 64–10000 bytes, including VLAN-tagged frames.

RIC-155L operation is based onVC-4/STS-3c.

The unit can be monitored, configured, and tested using the following ports and applications:
• Out-of-band via the local Ethernetmanagement port
• Inband via the network STM-1 port using a dedicated VLAN
• Using a highly scalable, Java-based multiplatform; RADview-EMS carrier class element management system, for
network configuration, provisioning, monitoring and management.

The Web-based management application provides remote device configuration and maintenance and is embedded into RIC-155L. This application can be accessed from any standard Web browser and is provided at no extra cost.

Remote (RLB) and local loopbacks (LLB) are used for physical layer troubleshooting.

RIC-155L provides user configurable, unidirectional fault propagation. The LAN link is deactivated if one of the following user-defined alarms is issued:
• LOS (Loss of signal)
• AIS (Alarm indication signal)
• RDI (Remote defect indication).

RIC-155L employs standard GFP encapsulation as per Generic Framing Procedure (ITU-T G.7041/Y.1303).

For prioritizing user traffic, RIC-155L features up to four separate queues. The queues handle traffic for different services based on VLAN priority (802.1p), which enables mapping the 8 priority levels of VLAN to 4 traffic classes.

The user can define the following SDH/SONET clock sources:
• Internal
• Recovered from STM-1/OC-3 interface.

RIC-155L operates with the following devices using standard encapsulation:
• RAD’s RICi-155GE (Central Ethernet gateway)
• RAD’s FCD-155E
• Third-party devices that employ standard GFP encapsulation.
