4000 Router Series Interface Module Guide

• The BSV interfaces support remote power supply and thus can be directly connected to ISDN

phones.

• MIM-4BSV is dedicated to voice applications, which is different from the BS interface modules

where BRI data applications are supported.

tion

LINK

• OFF means no link is present.

• ON means a link is present.

ACT

• Slowly flashing means data is being transmitted or received on B1 channel.

• Fast flashing means data is being transmitted or received on B2 channel.

• Steady ON means data is being transmitted or received on both B1 and B2

channels.

• Steady OFF means no data is being transmitted or received.

MIM-2FXO and MIM-4FXS/MIM-4FXO

Introduction

• 4-port voice subscriber circuit interface module (MIM-4FXS) serves to access and handle 2/4

channels of ordinary analog phone, fax, or AT0 loop trunk of telephone exchange.
