Gigabit Ethernet over TDM-based WANs

The MiRICi-E3/T3 is an intelligent SFP remote bridge, forwarding Fast Ethernet or Gigabit Ethernet traffic to TDM-based WANs at full duplex wire-speed. It enables quick and easy rollout of new Ethernet services over legacy TDM infrastructure, without the need for costly dedicated devices. The MiRICi-E3/T3 miniature Ethernet to E3/T3 remote bridge simplifies management, while saving space, power consumption and cabling.

Allowing service providers to adapt network interfaces as needed, the MiRICi-E3/T3 is ideal for delivering transparent LAN services and providing remote branch connectivity over leased lines and TDM-based WANs, for service providers, private enterprise and campus networks. In addition, it enables remote Ethernet connectivity over T3 radio links.

Standard encapsulation

The MiRICi E3/T3 SFP bridge supports standard GFP encapsulation to allow book-end connections as well as third-party GFP interoperability.

Advanced management capabilities

The MiRICi-E3/T3 miniature Ethernet to E3/T3 remote bridge can be monitored, configured, and tested using the following ports and applications:

• Out-of-band management via an I2C interface
• Inband management via the Ethernet port using a Web browser
  

The MiRICi-E3/T3 employs remote loopback (RLB) and local loopback (LLB) diagnostics for detecting and troubleshooting physical layer link failures. In addition, it enables WAN to LAN fault propagation alarms.

Flow control

To avoid overwhelming the WAN port, a flow control mechanism is activated if Fast Ethernet or Gigabit Ethernet traffic exceeds the WAN link capacity, sending Pause packets towards the LAN side.

The MiRICi-E3/T3 supports multi-source agreement (MSA) product identification codes and can operate opposite another MiRICi-E3/T3, installed on remote equipment.

Flexibility

The MiRICi-E3/T3 operates opposite remote MiRICi units or any Ethernet switch that supports standard GFP encapsulation.

SFP enclosure

The MiRICi-E3/T3 can be installed on any device that complies with the Multi-Source Agreement (MSA) specifications. Running on power derived from the host device, it requires no additional power supply
