Introduction

1.1 Overview

FCD-IPM is an E1/T1 or fractional E1/T1 Integrated Access Device (IAD), which enables service providers to bundle voice and Internet access services over a single E1 or T1 access line. FCD-IPM connects an Ethernet LAN to the Internet or Intranet through the integrated IP/IPX router or bridge. The connection is made via E1/T1/SHDSL links, operating at data rates of up to 2.048 Mbps for E1,

1.544 Mbps for T1 or 2.048 Mbps for SHDSL with optional backup for data using ISDN or PSTN networks. WAN data protocols supported are Frame Relay, PPP and MLPPP. FCD-IPM also supports two Ethernet LAN connections and provides two IO data channel slot options.

FCD-IPM provides transparent data and voice capabilities over the E1 or T1 access line, such as a synchronous data channel that supports user-selectable transmission rates, digital voice over sub E1 or T1 link that supports PBX and analog FXS, FXO and E&M voice ports.
