Introduction
•
MIM-8E1 module
The 8-port channelized E1/PRI interface module (MIM-8E1) transmits, receives, and processes
eight channels of E1 data traffic. In addition, you can use the module for other purposes, such
as CE1 access and the ISDN PRI function.
•
MIM-8E1-F module
The 8-port fractional E1 interface module (MIM-8E1-F) is different from the MIM-8E1 module in
the sense that:
The FE1 operating mode supported by the MIM-8E1-F module allows only one n No 64
kbps bundle to be formed on each interface, where n = 1 to 31. However, an MIM-8E1
module allows arbitrary grouping of 31 channels and therefore multiple bundles.
The MIM-8E1-F module does not support PRI mode.
NOTE:
For a MIM-8E1 module, the system automatically creates a serial interface for each timeslot bundle
formed on a controller E1 interface.
