Connecting MIM-8ASE/MIM-16ASE cable to a dumb terminal
Step 3: Check the behavior of the LINK LED on the MIM-8ASE/MIM-16ASE panel. It is
OFF when fault has occurred on the link and signal is out of synchronization. In this
case, please check the link.
3.6 MIM-1E1/MIM-2E1/MIM-4E1/MIM-1E1-F/MIM-2E1-F/MIM-4E
1-F Modules
3.6.1 Introduction
I. MIM-1E1/MIM-2E1/MIM-4E1
MIM-1E1/MIM-2E1/MIM-4E1, the 1-/2-/4-port channelized E1/PRI interface module,
transmits, receives, and processes E1 data traffic. In addition, you can use the card for
other purposes, such as CE1 access and the ISDN PRI function.
II. MIM-1E1-F/MIM-2E1-F/MIM-4E1-F
The MIM-1E1-F/MIM-2E1-F/MIM-4E1-F module is different from the
MIM-1E1/MIM-2E1/MIM-4E1 module in the sense that:
z
The FE1 operating mode supported by the E1-F cards allows only one n × 64 kbps
bundle to be formed on each interface, where n = 1 to 31. However, an E1 card
allows arbitrary grouping of 31 channels and multiple bundles.
z
The E1-F modules do not support PRI mode.
3.6.2 Interface Attributes
The interface attributes of MIM-1E1/MIM-2E1/MIM-4E1 and
MIM-1E1-F/MIM-2E1-F/MIM-4E1-F are given in the following table:
