MIM-1AE3 and MIM-1AT3 modules use the same type of cables for connection, which are called E3/T3
cables in this manual.
Connecting the interface cable
Some measures have been taken to protect MIM-1AE3 module. To achieve better lightning protection
effects, however, you are recommended to add a special lightning arrester at the input end of the E3/T3
cable when leading it to the outdoors.
Step1 Connect the SMB connector of an E3/T3 cable to the Tx port on MIM-1AE3 and another end to the Rx
port on the device to be connected;
Step2 Connect the SMB connector of another E3/T3 cable to the Rx port of MIM-1AE3 module and another
end to the Tx port on the device to be connected;
Step3 Check the behavior of the LINK LED on the MIM-1AE3 panel. It is OFF when fault has occurred on the
link and signal is out of synchronization. In this case, please check the link.
MIM-1AT3
Introduction
1-port 44.736 Mbps ATM-T3 interface module (MIM-1AT3) supports:
z
Two ATM cell mapping modes: ADM and PLCP;
z
Scrambling in data transmission;
z
Both line clock (when working as DTE interface) and internal clock (when working as DCE
interface);
z
Four types of test measures, i.e., local cell loopback, local payload loopback, remote payload
loopback, and remote line loopback.
