n
In the supported services described in the above table, CBR represents Constant
Bit Rate, rt_VBR represents Variable Bit Rate-Real Time, nrt_VBR represents
Variable Bit Rate-Non Real Time, and UBR represents Unspecified Bit Rate.
Interface LEDs MIM-1AE3 panel is shown in the following figure:
Figure 120 MIM-1AE3 panel
The following table describes the LEDs on the MIM-1AE3 panel:
Interface Cable External ports provided by MIM-1AE3 are two SMB sockets respectively
functioning as Tx end and Rx end for transmitting data and receiving data. The
ports work in 75-ohm unbalanced transmission mode and are connected to the
peer device using a pair of 75-ohm unbalanced coaxial cables. Several cable length
options are available.

MIM-1AE3 and MIM-1AT3 modules use the same type of cables for connection,
which are called E3/T3 cables in this manual.

CAUTION: 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.
Step 1: 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;

LINK OFF means no link is present; ON
means a link is present.
ACT OFF means no data is being
transmitted or received; blinking
means data is being received or/and
transmitted.
