3.16.5 Connecting the Interface Cable
Caution:
Some measures have been taken to protect MIM-1AT3 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.
Step 1: Connect the SMB connector of an E3/T3 cable to the Tx port of MIM-1AT3
module and another end to the Rx port on the device to be connected;
Step 2: Connect the SMB connector of another E3/T3 cable to the Rx port of MIM-1AT3
module and another end to the Tx port on the device to be connected;
Step 3: Check the behavior of the LINK LED on the MIM-1AT3 panel. It is OFF when
fault has occurred on the link and signal is out of synchronization. In this case, please
check the link.
3.17 MIM-1POS Module
3.17.1 Introduction
MIM-1POS represents the 1-port SDH/SONET interface module. It supports interface
rates up to 155.52 Mbps (STM-1/OC-3).
The MIM-1POS can use the protocols such as PPP, Frame Relay and HDLC at the data
link layer and IP at the network layer. It allows direct transmission of packets over
SONET/SDH. It supports:
z
Four SFP types: multi-mode short-haul (1310 nm), single mode medium-haul
(1310 nm), single mode long-haul (1310 nm), and single-mode ultra-long haul
(1550 nm).
z
155.52 Mbps fractional interface
