MIM-2FXO and MIM-4FXS/MIM-4FXO
Introduction
The MIM-2FXO and MIM-4FXS/MIM-4FXO modules transfer voice signals over data communication
networks.
• The 4-port voice subscriber circuit interface module (MIM-4FXS) can provide access for and
process 2/4 channels of ordinary analog phone, fax, or AT0 loop trunk of telephone exchange.
• The 2/4-port voice AT0 analog trunk interface module (MIM-2FXO/MIM-4FXO) can provide
access for and process 2/4 channels of common user lines of telephone exchange.
