HMIM-2E1/HMIM-4E1/HMIM-4E1-F
Introduction
The 2-port channelized E1/PRI interface module (HMIM-2E1) and 4-port channelized E1/PRI
interface module (HMIM-4E1) transmit, receive, and process E1 data traffic. In addition, you can use
these modules for CE1 access and ISDN PRI.
The HMIM-4E1-F module is different from the HMIM-4E1 module in the following ways:
• The FE1 operating mode supported by the E1-F module allows only one n × 64 Kbps bundle to
be formed on each interface, where the value range of n is 1 to 31. However, an E1 module
allows arbitrary grouping of 31 channels and multiple bundles.
• The E1-F modules do not support the PRI mode.
