Module
Introduction MIM-8T1 module
MIM-8T1, the 8-port channelized T1/PRI interface module, 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 module
MIM-8T1-F, the 8-port fractional T1 interface module is different from the 8T1
module in the sense that:
■ 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.
n
Given a MIM-8T1 module, the system automatically creates a serial interface for
each timeslot bundle formed on a controller T1 interface.
Interface Attributes The interface attributes of the MIM-8T1 and the MIM-8T1-F are given in the
following table:
Interface LEDs MIM-8T1 and MIM-8T1-F panels are similar. The following figure illustrates an
MIM-8T1 panel.
