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.
