MiRIC-E1, MiRIC-T1 Miniature Fast Ethernet to E1/T1 Remote Bridge
MiRIC-T1 and MiRIC-E1 forward LAN Fast Ethernet packets to TDM-based WAN at full duplex wire-speed, fully utilizing the expensive
E1 / T1 rate TDM circuit bandwidth. Housed in a Small Form Factor Pluggable (
SFP ) package, MiRIC-E1 and MiRIC-T1 comply with the Multi-Source Agreement (MSA). The RAD MiRIC-T1 and MiRIC-E1 handle 64 to 2016-byte frames, including
VLAN-tagged frames. LAN traffic is transported transparently, keeping the user LAN settings intact.

User-selectable transmit timing sources and data format are available:
Receive or internal clock
Framed or unframed
Management capabilities for configuration, status, and diagnostics via standard SFP I2C interface. LAN link fault is visually indicated
by the LINK LED turning off. T1 or E1 loss of signal is propagated by sending an electrical LOS signal to the LAN port, and is visually indicated by the LOS LED (red) turning on. This in turn can automatically turn off the LAN link. Automatically turning off the LAN link is configurable (enabled or disabled). Flow control mechanism is activated when LAN traffic exceeds the WAN link
( T1, E1 ) capacity; pause packets are transmitted towards the LAN port. Support for transparent flow of pause packet from LAN to WAN. MiRIC-E1 and MiRIC-T1 operate opposite another MiRIC-E1 or MiRIC-T1, or alternatively opposite RAD’s RICi-E1, RICi-T1, or Egate (central Ethernet gateway) devices. The MiRIC-T1 and MiRIC-E1 are autonomous plug-and-play modules. MSA product identification codes are supported. A special release mechanism allows the MiRIC-T1 and MiRIC-E1 to be easily extracted from the socket.
MiRIC-T1 and MiRIC-E1 Applications include:
Transparent LAN services over leased lines
Remote branch connectivity over T1 / E1 lines
Connecting LANs over T1 / E1 radio links
Campus applications – connecting remote LANs.
