MIRICi-155
Intelligent Miniature GbE over STM-1/OC-3 NTU

 Gigabit-to-STM-1/OC-3 bridge
 Gigabit Ethernet connectivity over SDH/SONET networks
 Standard GFP encapsulation
 Fault propagation to LAN link
 Inband and out-of-band management for configuration, monitoring and diagnostics
 I2C management interface for simple management integration with host devices

Connects Gigabit
Ethernet LANs overSTM-1/OC-3 links

MIRICi-155 is a state-of-the-art network
termination unit that bridges between
Gigabit Ethernet networks andSTM-1/OC-3 networks, providing simple,
efficient, and cost—effective Gigabit
Ethernet connectivity over SDH/SONET
networks.

automatically requests one from the DHCP
server upon booting.

MIRICi-155 offers a migration path forconnecting future-ready IP devices toexisting SDH/SONET networks.

Remote (RLB) and local loopbacks (LLB)
are used for physical layer
troubleshooting.

Typical applications include connecting
Gigabit Ethernet LANs over STM-1/OC-3
lines (Figure 1), and connecting Gigabit
Ethernet LANs over wireless STM-1/OC-3
links (Figure 2).

LOS AND FAULT PROPAGATIONThe unit supports frame sizes of 64–
10000 bytes, including VLAN-tagged
frames.
MANAGEMENTThe unit can be monitored, configured,and tested using the following ports andapplications:Out-of-band via the I2C channel (offthe SFP edge connector)
Inband via the Ethernet port using a
Web browser.

Application software can be downloaded
to MIRICi-155 via the central server, using
TFTP.
DIAGNOSTICS

The LAN link is deactivated if one of thefollowing user-defined alarms is issued
and fault propagation is enabled:LOS (Loss of Signal)

AIS (Alarm Indication Signal)

RDI (Remote Defect Indication).

In addition, the above-listed error
conditions are propagated towards thehost by sending an electrical signal via the
LOS pin on the MSA edge connector.
ENCAPSULATIONMIRICi-155 uses standard GFP
encapsulation according to
ITU-T G.7041/Y.1303 requirements.

To facilitate integration of a new device
into an IP network, if no IP address has
been manually configured, MIRICi-155

MIRICi-155
Intelligent Miniature GbE over STM-1/OC-3 NTUQUALITY OF SERVICE – QOS
For prioritizing user traffic, MIRICi-155
features up to four separate queues.
The queues handle traffic with different
services based on VLAN priority (802.1p),
which enables to map the 8 priority levels
of VLAN to 4 traffic classes.

Running on power derived from the hostdevice, it requires no additional power
supply.
MIRICi-155 is hot swappable and featuresa special release mechanism for easy
extraction from the SFP socket.

The user can define the following
SDH/SONET clock sources:
Internal

Recovered from STM-1/OC-3 interface.

SFP ENCLOSURE
Housed in a Small Form Factor Pluggable(SFP) package (Figure 3), MIRICi-155
complies with the Multi-Source Agreement(MSA).

Possible applications include Gigabit
Ethernet LANs over STM-1/OC-3 lines(Figure 1) and Gigabit Ethernet LANs overwireless STM-1/OC-3 links (Figure 2).
FLEXIBILTYSFP CONFIGURATION ADAPTER
SDH/SONET TIMING OPTIONSPOSSIBLE APPLICATIONS

An optional configuration adapter module,
SFP-CA (Figure 4), is available for
configuring MIRICi-155 by connecting it toa PC via a USB port. The configuration
adapter is used for preliminary
configuration such as assigning an IP
address for first use or specifying themode of operation. It is also used todownload software to the MIRICi-155
units.

MIRICi-155 operates with the following
devices using standard encapsulation:
RAD’s RICi-155GE (Central Ethernet
gateway)RAD’s FCD-155E



Third-party devices that employ
standard GFP encapsulation.
