Introduction
The 2-port channelized CT1/PRI interface module (HMIM-2T1) transmits, receives, and handles T1
data streams. In addition, you can use the module for CT1 access and ISDN PRI.
The 4-port fractional T1 interface module (HMIM-4T1-F) differs from the HMIM-CT1 module in the
following ways:
•
FT1 operating mode supported by T1-F modules allows only one bundle. The time slots can
only be bundled into one n × 64 Kbps/56 Kbps channel, where the value range of n is 1 to 24.
However, a CT1 module allows of arbitrary grouping of the 24 channels.
•
T1-F does not support the PRI mode.
NOTE:
For a T1 module, the system automatically creates a serial interface for each timeslot bundle formed
on a controller T1 interface.
