MIM-8T1/MIM-8T1-F
Introduction
• MIM-8T1
The 8-port channelized T1/PRI interface module (MIM-8T1) transmits, receives, and processes
eight channels of T1 data traffic. In addition, you can use the module for other purposes, such
as CT1 access and the ISDN PRI function.
• MIM-8T1-F
The 8-port fractional T1 interface module (MIM-8T1-F) differs from the 8T1 module in the
following ways:
The FT1 operating mode supported by the MIM-8T1-F module allows only one n × 64 kbps
or n × 56 kbps bundle to be formed on each interface, where n = 1 to 24. However, the
MIM-8T1 module allows arbitrary grouping of 24 channels and therefore multiple bundles.
The MIM-8T1-F module does not support PRI mode.
a MIM-
8T1 module, the system automatically creates a serial interface for each timeslot bundle
formed on a controller T1 interface.
