•E&M trunks interface to the system using the E&M trunk card in the peripheral cabinet. The card can be configured for either
•Direct Inward Dial and Tie trunks interface to the system through the DID/Loop Tie trunk card in the peripheral cabinet.
IP Networking
IP Networking provides an integrated networking solution that allows voice and signaling data to be transported over the existing LAN/WAN infrastructure between multiple 3300 ICPs. MSDN/DPNSS features are supported over IP Networking.
Each 3300 ICP supports up to 2000 IP trunks allowing for a ’cluster’ of up to 80 3300 ICP systems to work as a single integrated voice system. Each pair of 3300 ICP systems can be connected by up to 200 IP trunks.

ISDN (Integrated Services Digital Network)
ISDN Support
The Integrated Services Digital Network (ISDN) transmits voice, data, and video at high speeds. ISDN services can be deployed and accessed at enterprise, department, and desktop levels by adding the 3300 Universal NSU with PRI or the 3300 BRI NSU.
LAN traffic can also be carried over existing private or public digital network connections on Euro ISDN, DASSII (public access) protocols, or even on a private MSDN/DPNSS network using ISDN connections to a router.
ISDN Connectivity
ISDN access lets customers leverage the advantages of ISDN network services for both voice and data applications, effectively improving performance and network resource management while controlling costs.
The 3300 ICP supports multiple ISDN protocols and provides ISDN connectivity. The system connects with the ISDN public network and data devices (such as routers, video conferencing equipment, and servers) by using Primary Rate Interface (PRI) or Basic Rate Interface (BRI). ISDN takes advantage of the following features to capture and control costs, analyze peak periods, and fine tune network resources accordingly for both voice and data calls:
•ARS/LCR (Automatic Route Selection / Least Cost Routing)
•SMDR (Station Message Detail Recording)
•Min/Max Traffic Control
•Per Call Service Selection
•Limited Toll Restriction
•Trunk Diagnostics
•NFAS
•Remote LAN Access.
