ETHERNET OVER TDM

RICi-E1, RICi-T1,

RICi-E3, RICi-T3

Fast Ethernet over

E1/T1 or E3/T3 NTUs

The RICi-E1, RICi-T1, RICi-E3 and RICi-T3 are

network termination units (NTUs) connecting

Fast Ethernet over unframed/framed E1/T1 or T3

circuits, or a single unframed E3 circuit.

Typical applications include:

•

Ethernet Private Line services

•

Layer 2 VPN services

•

Backhauling of network management traffic

•

IP DSLAM and WiMAX base station backhaul

•

Inter-office or enterprise LAN connection

The devices can interoperate with third-party

devices using standard protocols: HDLC framing,

GFP (RICi-E1/RICi-T1) and X.86/LAPS

(RICi-E3/RICi-T3).

The devices support VLAN priority (802.1p) and

IP Precedence (RICi-E1/RICi-T1), enabling users

to define different levels of quality of service

(QoS) according to application requirements.

VLAN capabilities

The VLAN tagging, stacking and stripping option

enables transparent delivery of user traffic,

keeping all user VLAN settings intact.

The built-in Fast Ethernet bridge can work in

filter mode, where it learns MAC addresses and

filters local traffic, or in transparent mode,

where any received packet will be forwarded to

the other interface. The device can also operate

in VLAN-aware mode, switching traffic according

to VLAN tags and MAC address (IVL mode).

SNMP management

The RICi-E1, RICi-T1, RICi-E3 and RICi-T3 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. 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 RICi-E1, RICi-T1, RICi-E3 and RICi-T3 also

support a variety of access protocols, including

Telnet, SNMP, Web server, and TFTP. DHCP client

support is employed to automatically obtain IP

address, IP mask and default gateway, saving

precious installation time. All four devices

support diagnostic tools for TDM and Ethernet

networks, for fast isolation of network problems,

saving time and costs. Remote and local loopbacks

are used to isolate problems on the physical layer,

while ping, trace-route and ICMP messages enable

diagnostics of the Ethernet layer.

In cases of error conditions on the TDM port, a

fault propagation feature disconnects the link on

the Fast Ethernet port, and enables routers on

both ends of the link to reroute the traffic.
