RIC-155GE

Gigabit Ethernet over STM-1/OC-3 NTU

The RIC-155GE is a network termination unit

(NTU), providing cost-effective bridging of

Gigabit Ethernet traffic over STM-1/OC-3 access

or channelized OC-3 circuits.

Typical applications include IP DSLAM and

WiMAX base station backhaul, inter-POP

connectivity or high bandwidth private line

services. Using VLAN tagging and stacking,

Ethernet traffic can be delivered transparently,

while keeping user VLAN (CE-VLAN ID) settings

intact.

The RIC-155GE is equipped with either a

1000BaseSX/LX optical LC connector or a

1000BaseTX electrical Ethernet interface. The

optical STM-1/OC-3c network interface includes

single mode and multimode options.

The RIC-155GE maps Ethernet frames into four

fixed priority queues towards the network port,

based on VLAN priority tagging (802.1p). This

enables prioritizing and differentiation between

various user applications.

Advanced management options

The RIC-155GE 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,

Administration, Performance, Security) and

diagnostic tools are provided by

RADview-EMS, RAD’s carrier-class element

management system, via a Web browser.

The RIC-155GE also supports a variety of access

protocols, including Telnet, SNMP, Web server,

and TFTP. Incorporated security features include

SNMPv3 and RADIUS.

The device collects statistics at the Ethernet

physical layer and the STM-1/OC-3c interface

frame counters.

The RIC-155GE is 1U-high, half 19-inch wide

with a rack-mount option, and is available with

AC or DC power supply. It is also available as a

level 3 NEBS-compliant box with power supply

redundancy.
