Note:
z
MIM-1CE3 and 1CT3 adopt the same cable, which is called E3/T3 cable in this
manual.
z
The standard shipment package of MIM-1CE3 does not include the interface cable.
3.10.5 Connecting the Interface Cable
Caution:
Some measures have been taken to protect the MIM-1CE3 module. To achieve better
lightning protection effects, however, you are recommended to add a special lightning
arrester at the input end of the E3 or T3 cable when it is led outdoors.
Step 1: Connect the SMB connector of an E3 or T3 cable to the Tx port of MIM-1CE3
and another end to the Rx port of the device to be connected;
Step 2: Connect the SMB connector of another E3 or T3 cable to the Rx port of
MIM-1CE3 and another end to the Tx port of the peer device;
Step 3: Check the behavior of the LINK LED on the MIM-1CE3 panel. It is OFF when
the line is faulty and signal is out of synchronization. In this case, check the link.
3.11 MIM-1CT3 Module
3.11.1 Introduction
1-port channelized T3 interface module (MIM-1CT3) serves to:
z
Transmit/Receive and handle one channel of T3 fast traffic, as well as provide the
accessing of T3 traffic when working in T3 mode; and
z
Provide the low-speed accessing service at the speed of n × 64 kbps or 56 kbps,
where n is smaller than or equal to 128, when working in CT3 mode.
