ETHERNET OVER TDM

RIC-LC, RIC-155L

Ethernet Converters for Multiple PDH Circuits

or STM-1/OC-3

The RIC-LC is a Fast Ethernet converter,

delivering LAN traffic over four, eight or 16

bonded E1 circuits using Ethernet over NG-PDH

encapsulation and bonding techniques. The

RIC-155L provides transparent delivery of

Gigabit Ethernet traffic over STM-1 or OC-3

lines. Both devices are ideal for extending

Ethernet connectivity over TDM backbones in

point-to-point applications, and for cost-

effective backhaul of IP DSLAM traffic over PDH

and SDH access networks. The RIC-LC can also

work opposite Ethernet over TDM demarcation

devices and aggregators, such as RAD’s

RICi-4/8/16E1 and Egate-100, respectively.

Ethernet over NG-PDH encapsulation and

bonding

The RIC-LC supports standard Ethernet over

NG-PDH protocols, including GFP (generic

framing procedure), VCAT (virtual concatenation)

and LCAS (link capacity adjustment scheme).

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

stopping the service. The RIC-155L uses GFP to

map Ethernet traffic to SDH/SONET lines.

Ethernet capabilities

Featuring four Fast Ethernet user ports, the

RIC-LC supports VLAN-aware and VLAN-unaware

bridging, as well as VLAN stacking (Q-in-Q). It

maps Ethernet frames into four priority queues

based on user port, VLAN priority (802.1p) or

ToS marking, to enable differentiation between

various user applications. The RIC-LC supports

both Strict Priority and WFQ (weighted fair

queuing), as well as per-port rate limitation.

The RIC-155L features two Fast Ethernet/Gigabit

Ethernet user interfaces and supports QoS per

VLAN priority, with four priority queues based

on Strict Priority scheduling.

Management options

The devices feature the following management

alternatives:

RIC-LC:

•

Local management via an ASCII terminal

(RS-232)

•

Out-of-band management using one of the

user ports
