MiRICi-E3T3
Intelligent Miniature Ethernet to E3/T3 Remote Bridge• E3/T3 connectivity to any Ethernet device with SFP MSA-compatible socket• Full duplex, E3/T3 wire-speed packet forwarding• GFP, RAD HDLC and cHDLC encapsulation• VLAN support according to 802.1p, including VLAN stacking (Q-in-Q) capabilities,
allowing traffic separation and prioritization• 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 devicesMiRICi-E3T3 forwards Fast or Gigabit
Ethernet packets to a TDM-based WAN atfull duplex wire-speed, fully utilizing theexpensive E3 or T3 TDM bandwidth.
The TDM interface type (E3 or T3) isuser-configurable.

Connecting Fast orGigabit Ethernet LANs
over framed/unframed
E3 or T3 links

The unit transmits the following framesizes, including VLAN-tagged frames:••

64–2016 bytes for Fast Ethernet
64–10000 bytes for Gigabit Ethernet.

LAN traffic is transparently directed, thus
preserving the user LAN settings.
All parameters are user-configurable
including transmit timing sources and dataformats.
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 aWeb browser.
To facilitate integration of a new device
into an IP network, if no IP address has
been manually configured, MiRICi-E3T3
automatically requests one from the DHCP
server upon booting.

MiRICi-E3T3 sends SNMP traps to up toeight management stations.
Application software can be downloaded
to MIRICi-E3/T3 via the central server,using TFTP.
LOS AND FAULT PROPAGATIONThe LAN link is deactivated and the linkstatus LED turns off if one of thefollowing user-defined alarms is issued
and fault propagation is enabled:• LOS (Loss of Signal)• LOF (Loss of Frame)• FEAC (Far-end Alarm and Control)• RLOL (Receive Loss of Lock)• AIS (Alarm Indication Signal)• RDI (Remote Defect Indication).
In addition, the above-listed error typeindications are propagated towards thehost by sending an electrical signal via theLOS pin on the MSA edge connector. TheLOS LED turns ON, visually indicating theLOS condition.

ENCAPSULATIONMiRICi-E3T3 employs the GFP, RAD HDLC
and cHDLC WAN encapsulation protocols.
FLOW CONTROL
A flow control mechanism is activatedwhen LAN traffic exceeds the WAN link
(E3/T3) capacity and the watermarks of
the internal frame buffer. Pause packets
are transmitted to the LAN port, halting
LAN traffic until the buffer has been
emptied to below the watermark limit.
QUALITY OF SERVICE (QOS)
MiRICi-E3T3 facilitates differentiatedservices on the same link according toEthernet or IP marking. Classification isbased on VLAN (802.1p) or DifferentiatedServices Code Point (DSCP) priority, whileclassification results are mapped totransmit priority queues. Priority queues
can be defined to be Strict Priority or
Weighted Round Robin (WRR).
DIAGNOSTICS AND LOOP DETECTION
Remote (RLB) and local loopbacks (LLB)
are used for physical layer
troubleshooting.
MiRICi-E3T3 detects loops on the WAN orthe LAN side by transmitting special loop
detection frames.
If a loop is detected on the LAN side, aloop detection alarm is sent

unit blocks the traffic and only then a loop
detection alarm is sent.
The unit also performs Bit Error Rate(BERT) diagnostic tests. MiRICi-E3T3
generates and detects pseudo-random
patterns and repetitive patterns from 1 to32 bits in length.
ETHERNET OAM
MiRICi-E3T3 provides single segment (link)
OAM based on 802.3ah, including
discovery, continuity check, and remotefault indication.
CLOCK OPTIONSMiRICi-E3T3 uses Tx clock sources for theinternal and receive clocks. Standard
statistics for 15-minute time intervals arecollected.
FLEXIBILITY
MiRICi-E3T3 operates opposite thefollowing devices using standard GFP, RAD
HDLC and cHDLC encapsulation:••

RAD’s RICi-16, RICi-E3 and RICi-T3
Third-party devices that support
standard GFP, RAD HDLC and cHDLC
encapsulation.

SFP ENCLOSURE
Housed in a Small Form Factor Pluggable(SFP) package, MiRICi-E3T3 complies withthe Multi-Source Agreement (MSA).
Running on power derived from the hostdevice, it requires no additional power
supply.
MiRICi-E3T3 is hot swappable and featuresa special release mechanism for easy
extraction from the SFP socket.
SFP CONFIGURATION ADAPTER
An optional configuration adapter module,
SFP-CA, is available for configuring
MiRICi-E3T3 by connecting it to a PC via aUSB port.
The configuration adapter is used forpreliminary configuration, such as
assigning an IP address for first use or
specifying the operation mode. It is used
as well to download software to theMiRICi-E3T3 units.
POSSIBLE APPLICATIONSMiRICi-E3T3 can be used in the followingapplications:•••

Transparent LAN services over leased
lines
Remote branch connectivity over E3/T3lines
Connecting LANs over E3/T3 radio links
or in campus applications.
