RICi-16 is a network termination unit (NTU)

connecting Fast Ethernet or Gigabit Ethernet LANs

over multiple bonded PDH links, enabling service

providers to extend high capacity Ethernet–based

services to remote locations. RICi-16 is also used to

backhaul Ethernet traffic from HSDPA IP Node Bs,

IP DSLAMs and WiMAX base stations over copper-

based or microwave PDH connections.

The RICi-16 features up to four Fast Ethernet user

ports, or two Gigabit Ethernet and two Fast

Ethernet ports, with three different uplink

configuration options:

•

Up to 16 framed/unframed E1/T1 ports

•

Two bonded clear channel T3 ports

•

Single channelized T3 port. When selecting

this option, the 16 T1 interfaces serve as user

ports and are multiplexed into the T3 link

together with Ethernet traffic.

The RICi-16 is MEF-9 and MEF-14 certified for

Ethernet Private Line and Ethernet Virtual Private

Line services.

RICi-16 features a "pay-as-you-grow" license

model, allowing the addition of E1/T1 links

according to the customer's bandwidth

requirements.

Ethernet over NG-PDH encapsulation

and bonding

RAD’s RICi-16 supports MLPPP bonding as well

standard Ethernet over NG-PDH protocols,

including GFP (G.8040, G.7041), VCAT (G.7043)

and LCAS (G.7042).

These protocols allow service providers to

dynamically allocate bandwidth to their customers

by simply changing the number of links bonded

to the virtual group, without the need to change

the NTU device or stop the service. In addition,

the RICi-16 supports up to 16 GFP VCAT groups

(VCG), allowing the connection of up to 16

different customers per site.

Enhanced service delivery capabilities

The RICi-16 is equipped with advanced,

software-based capabilities for handling multi-

priority traffic, ensuring latency, jitter and packet

delivery performance on a per-flow basis. The

device supports traffic classification according to

any user-defined criteria, including VLAN ID, VLAN

priority (P-bit), DSCP/ToS, subscriber port, and

others, as well as their combinations. In addition,

metering, policing and shaping functionalities help

carriers rate-limit user traffic according to pre-

defined CIR (committed information rate) and EIR

(excess information rate) profiles, thereby

supporting customized service packages and

enabling carriers to introduce new revenue

generators. These capabilities enable service

differentiation and SLA guarantees.

VLAN stacking and color-sensitive P-bit

re-marking

By supporting VLAN stacking (Q-in-Q), the

RICi-16 enables service providers to ensure

transparent delivery of user traffic, while

minimizing the number of required VLAN IDs in

the network. In addition, the RICi-16 features

unique P-bit re-marking capabilities, which assign

color-specific P-bit values to Ethernet frames at

the network ingress to ensure metering continuity

across the Metro Ethernet network. User traffic

that was marked “yellow” according to the

CIR/EIR parameters by the device’s QoS engine is

assigned a new P-bit value to signal its status

and priority, so that it is dropped first by 802.1Q

and 802.1ad network elements in the event of

congestion. This is especially useful in color-blind

as well as in color-aware networks with no

“discard eligible” (“yellow”) marking.

SNMP management

The RICi-16 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 an SNMP-based GUI.

The RICi-16 also supports a variety of access

protocols, including CLI over Telnet, SNMP, Web

server, and TFTP. Incorporated security features

include Secure Shell (SSH), Web-based Secure

Socket Layer (SSL), SNMPv3, and RADIUS, as well

as management access control list (ACL).
