Gigabit Ethernet over STM-1/OC-3

or STM-4/OC-12 NTUs

GFP or X.86 encapsulation with virtual

concatenation enables Ethernet bandwidth to

be configured in various increments for cost-

effective adaptation of the SDH/SONET

infrastructure. These increments are as follows:

•

SDH: 2 Mbps (VC-12), 50 Mbps (VC-3),

155 Mbps (VC-4, RICi-622GE only)

•

SONET: 1.5 Mbps (VT 1.5), 50 Mbps (STS-1),

155 Mbps (STS-3, RICi-622GE only)

This eliminates the rigid bandwidth restrictions

usually imposed by SDH/SONET virtual

containers and allows for scalable and efficient

delivery of next-generation Ethernet services

over TDM networks. In addition, the devices

support up to 32 low-order VCAT groups (VCGs),

allowing the connection of up to 32 different

customers per site.

The RICi-155GE and RICi-622GE are MEF-9 and

MEF-14 certified for Ethernet Private Line (EPL)

and Ethernet Virtual Private Line (EVPL) services.

Typical applications include IP DSLAM and WiMAX

base station backhaul, inter-POP connectivity or

high bandwidth private line services.

Ethernet QoS and rate limitation

The devices map Ethernet frames into a flexible

priority queuing mechanism. The traffic can be

mapped according to several parameters,

including ingress port number, VLAN priority, IP

Precedence, and DSCP. Rate limitation can be

performed per Ethernet flow or per EVC.CoS at

the ingress side, and per port at the egress side.

Using VLAN tagging and stacking (802.1Q and

Q-in-Q), Ethernet traffic can be delivered

transparently, keeping user VLAN settings

(CE-VLAN ID) intact.

SNMP management

The RICi-155GE and RICi-622GE feature 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 or the data communication

channel (DCC). 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 devices also support a variety of access

protocols, including Telnet, SNMP, Web server,

and TFTP. Incorporated security features include

Secure Shell (SSH), Web-based Secure Socket

Layer (SSL), SNMPv3, and RADIUS.

The devices collect statistics at the Ethernet

physical layer and the SDH/SONET interface

frame counters.

The RICi-155GE is equipped with dual

1000BaseSX/LX optical or 1000BaseTX electrical

Gigabit Ethernet interfaces. All fiber optics are

SFP-based.

The RICi-155GE and RICi-622GE are 1U-high,

19-inch wide boxes with a rack-mount option.

23-inch wide enclosures, which are NEBS-

compliant, are available as well.

Redundant hot-swappable AC or DC power

supplies provide carrier-class reliability.

Backhauling IP DSLAMs over STM-4/OC-12 uplinks

For latest updates visit www.rad.com

The RICi-155GE and RICi-622GE Ethernet network

termination units (NTU) provide simple, efficient

and cost-effective Gigabit Ethernet (GbE)

connectivity over two STM-1/OC-3 or over two

STM-4/OC-12 uplinks, supporting bundled access

rates of 300 Mbps and 1/2 Gbps, respectively. It

offers a migration path by connecting future-ready

IP devices with 10/100/1000 Mbps interfaces to

existing SDH/SONET networks, using standard GFP,

VCAT and LCAS technology.
