Local loopback can be activated when MiRICi-E3T3 operates with the internal
clock.
Remote Loopback
MiRICi-E3T3 can be set to start a remote loopback to test the connection
between the E3/T3 port and the WAN. In this mode, data coming from the WAN
is both looped back to the WAN and transmitted towards the host connected to
the E3/T3 port.

Activating T3 Inband Loopbacks
T3 physical loopbacks can be activated by receiving a loopback activation code
from the TDM equipment connected to the T3 port. When MiRICi-E3T3 receives a
loopback activation code, it closes a remote loopback.
Sending RDI or AIS to the TDM Equipment
MiRICi-E3T3 can be configured to transmit RDI and AIS indications to the TDM
equipment connected to the E3/T3 port.
³ To transmit RDI or AIS to the TDM equipment:
• From the Diagnostics menu, set TRDI or TAIS to Enable.
MiRICi-E3T3 starts inserting RDI or AIS into TDM data that are sent to the
adjacent E3/T3 device.
