RIC-155

Fast Ethernet over STM-1/OC-3 NTU

RAD’s RIC-155 Fast Ethernet over STM-1/OC-3 network termination unit bridges Fast Ethernet LANs over an STM-1/OC-3 uplink, providing carriers and service providers with a migration path for connecting future-ready IP devices with Fast Ethernet interfaces, into existing SDH/SONET networks at 155 Mbps access rates.

An intelligent Fast Ethernet to STM-1/OC-3 converter, RIC-155’s typical applications include IP backhaul between POPs, transporting Fast Ethernet traffic over 155 Mbps microwave links, or extending high bandwidth private line services over SDH/SONET networks. Using VLAN tagging and stacking, Ethernet traffic can be transported transparently, keeping user VLAN settings intact.

Applications

Connects 10/100BaseT LANs over STM-1/OC-3 circuits

Transparent transport of user traffic using VLAN tagging and stacking

SNMP fault management, Web-based element management

A large variety of optical modules and a coax SDH/SONET interface

Fast and easy deployment of Ethernet services over SDH/SONET networks
Ideal for large enterprises, inter-POP connectivity
Interoperable with standards-based third party devices
Minimizes service disruption and reduces operating costs via sophisticated diagnostic tools

RIC-155 is a network termination unit (NTU) for simple, efficient and cost-effective transport of Fast Ethernet traffic over STM-1/OC-3 lines. The device enables carriers and service providers to easily extend their customer reach over 155 Mbps microwave links and legacy SDH/SONET backbones. A VLAN tagging and stacking option supports transparent inter-LAN connectivity and keeps all the user VLAN settings intact.

An intelligent 10/100BaseT to STM-1/OC-3 converter and Ethernet extender, RIC-155’s unique features make it ideal for the following applications:

Connecting large enterprises over SDH/SONET
Backhauling IP traffic between POPs
Economical alternative to a STM-1/OC-3c router interface

SNMP management

The RIC-155 features flexible management capabilities, including local management via an ASCII terminal (RS-232). In addition, remote management can be performed either inband or out-of-band, using the network or user ports, while maintaining separation between management and user traffic via the use of VLANs. Advanced FCAPS (Fault, Configuration, Accounting, Performance, Security) and diagnostic tools are provided by RADview-EMS, RAD’s carrier-class element management system, via a Web browser.

The RIC-155 also supports a variety of configuration access channels, including Telnet, SNMP, Web server, and TFTP.

The devices collect statistics at the Ethernet physical layer and the STM-1/OC-3c interface
frame counters.In cases of severe error conditions on the SDH/SONET interface, an optional fault propagation feature disconnects the Ethernet port, indicating to the Ethernet network the error conditions on the TDM network and enabling connected routers to redirect the traffic.

The RIC-155 is a 1U-high, half 19-inch wide box with a rack mount option. It is available with an AC or DC power supply.
