RICi-16 is a state-of-the-art Network Termination Unit (NTU) connecting Fast Ethernet LANs over up to 16 bonded E1/T1 lines or up to two clear-channel T3 circuits. Alternatively, RICi-16 transports Ethernet over bonded and TDM T1s using a single channelized T3 as uplink.

This enables service providers to supply high-capacity Ethernet services to remote locations, and transparently connects corporate LANs over existing PDH infrastructure.

Increases bandwidth capacity of available infrastructure with scalable bonding, bridging the bandwidth gap between E1/T1 rates and E3/T3 rates

An essential part of RAD’s EtherAccessTM portfolio, RICi-16 features Carrier Ethernet attributes, that include Ethernet OAM for proactive SLA monitoring, quality of service (QoS) per Ethernet flow, and advanced traffic management capabilities, all starting at the service hand-off points.

MARKET SEGMENTS AND APPLICATIONS

Typical applications include:

• IP DSLAM, cellular IP, and WiMAX base station backhauling
• Interoffice or enterprise LAN connection.

ETHERNET

Certified by the Metro Ethernet Forum (MEF) for the following services:

• MEF 9: EPL, EVPL
• MEF 14: EPL, EVPL

Encapsulation and Bonding

RICi-16 employs Ethernet over NG-PDH technologies, such as Generic Framing Procedure (GFP G.8040), Virtual Concatenation (VCAT G.7043) and Link Capacity Adjustment Scheme (VCAT G.7042). NG-PDH solutions improve overall network availability by reducing latency and optimizing line utilization and throughput. The unit supports up to 16 GFP VCAT groups (VCG), allowing the connection of up to 16 different customers per site.

Traffic Management

Traffic is mapped to the Ethernet flows (EVCs) using the following per-port criteria:

• Port-based (All-to-one bundling)
• CE-VLAN
• CE-VLAN priority
• DSCP
• IP precedence
• CE-VLAN + CE-VLAN priority
• CE-VLAN ID + IP precedence (user to network only)
• CE-VLAN + DSCP (user to network only)
• Non-IP
• CE-VLAN + non-IP
• Untagged.

VLAN stacking and stripping at ingress and egress enables transporting user traffic transparently, keeping the user VLAN settings intact. In addition, the management traffic can be tagged with a different VLAN, fully separating user traffic from management data. 

MANAGEMENT AND SECURITY

• Remote inband management via the network ports using Telnet, Web browser or RADview, RAD’s SNMP-based management system
• Out-of-band management via one of the user data ports that can be configured as a management port
• Local management via an ASCII terminal connected to the RS-232

To provide a high level of client-server communication security, the following security protocols are supported:

• SNMPv3
• RADIUS authentication
• SSL for Web-based management
• SSH for Secure Shell communication.
