MiRICi-E1/T1,

MiRICi-E3/T3

Miniature Ethernet to E1/T1

or E3/T3 Remote Bridges

connectivity over E1/T1 and E3/T3 circuits, as

well as over radio links. Deriving power from the

host device, they require no additional power

supply. The MiRICi devices are simple and cost-

effective alternatives to external, standalone

bridge units or conversion cards for user devices,

saving on space, cabling and power

consumption, and simplifying management.

The low cost SFP plug format is an ideal and

affordable solution for carriers and service

providers bridging Fast Ethernet LANs over TDM-

based WANs, as well as for similar applications

in private enterprise and campus networks. The

MiRICi units permit easy adaptation of

equipment with fiber optic Fast Ethernet

interfaces for transmission over TDM-based

infrastructures. If the transport network changes

to Ethernet, the MiRICi can be quickly removed

and reused elsewhere.

Inband and out-of-band management

Enhanced management for control status is

supported via inband Ethernet packets and

out-of-band I

The MiRICi bridges forward LAN Ethernet packets

to the TDM-based WAN at wire-speed, fully

utilizing the expensive E1/T1 and E3/T3 TDM

circuit bandwidth.

LAN traffic is transported transparently, thus

keeping user LAN settings intact. The bridges

handle 64 to 2016-byte frames, including VLAN-

tagged frames. The MiRICi devices support

jumbo frames when working with GbE.

The MiRICi products support standard GFP

encapsulation (G.8040, G.7041/Y.1303) for

book-end connections as well as third-party GFP

interoperability.

On the WAN side, each bridge has a single

E1/T1 or E3/T3 interface, terminated in an RJ-45

or unbalanced 75Ω SMB connector, respectively.

For controlled bandwidth adjustment between

LAN and WAN, a flow control mechanism is

activated.

Pause frames are generated whenever the

internal buffer reaches its high water mark.

The bridges support Multisource Agreement

(MSA) product identification codes. Once

plugged in, they begin to operate autonomously

without any need for software configuration.

The bridges are hot-swappable and feature a

special release mechanism for easy extraction

from the SFP socket.

MiRICi-E1/T1 and MiRICi-E3/T3 can operate

opposite their respective MiRICi units installed

on remote equipment. Alternatively, they can

work opposite any Ethernet switch or device

that supports standard GFP such as RAD’s

RICi-E1, RICi-T1 and RICi-16 Fast Ethernet over

E1/T1 NTUs, or RAD’s Egate-100 channelized

Ethernet gateway.

Providing transparent LAN services over E1/T1 and E3/T3 leased lines

The innovative SFP-format MiRICi-E1/T1 and

MiRICi-E3/T3 remote bridges connect Fast Ethernet

or GbE LANs over framed or unframed E1/T1 and

E3/T3 circuits. Housed in a small form-factor

pluggable (SFP) enclosure, they are designed for

quick and simple insertion into any Ethernet device

port with a compatible SFP socket. These unique

devices are perfect for providing transparent LAN

services over leased lines and remote branch
