MiRICi-155


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

MIRICi-155 offers a migration path for connecting future-ready IP devices to existing SDH/SONET networks.

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 

The unit supports frame sizes of 64–10000 bytes, including VLAN-tagged frames.

 

Highlights

  • 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

 

QUALITY 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.

 

SDH/SONET TIMING OPTIONS

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

  • Internal
  • Recovered from STM-1/OC-3 interface

 

ENCAPSULATION

MIRICi-155 uses standard GFP encapsulation according to ITU-T G.7041/Y.1303 requirements.

 

FLEXIBILTY

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
