Introduction
This document provides a sample configuration for the IP Communications High−Density Digital Voice/Fax
Network Module feature, which supports high−density digital voice and low−density analog voice
connectivity along with data and integrated access connectivity. The network modules offer built−in T1/E1
ports, and include a single voice interface card (VIC)/voice WAN interface card (VWIC) slot for Foreign
Exchange Station (FXS), Foreign Exchange Office (FXO), E&M, software−configured Centralized Automatic
Message Accounting (CAMA), direct inward dialing (DID), BRI, or E1 and T1 cards, up to a maximum of
four T1/E1 ports. The network modules also support up to 32 HDLC channels with an aggregate capacity of
2.048 Mbps.
