Remote Loopback
MiTOP-E1/T1 can be set to start a remote loopback to test the connection
between the E1/T1 port and the PBX. In this mode, data coming from the PBX is
both looped back to the PBX and transmitted towards the PSN.
Remote loopback can be activated only when MiTOP-E1/T1 operates with the
internal clock.

Activating T1 Inband Loopbacks
T1 physical loopbacks can be activated by receiving a loopback activation code
from TDM equipment connected to the T1 port. When MiTOP-E1/T1 receives a
loopback activation code, it closes a remote loopback.

equipment connected to the E1/T1 port.

• From the Diagnostics menu, set TRDI or TAIS to Enable.
MiTOP-E1/T1 starts inserting RDI or AIS into TDM data sent to the
adjacent E1/T1 device.
