Gigabit Ethernet pārraide caur SDH / SONET tīkliem
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
