Lucent Technologies Network Card 8 Port DS3 E3 User Manual

8-Port DS3/E3 ATM Module for the  
®
CBX 500 and CBX 3500  
Multiservice Switches  
The 8-Port DS3/E3 ATM Input/Output Module provides industry-standard DS3 physical  
connections and service interfaces to the CBX 500® and CBX 3500™ switches, and E3 physical  
connections and service interfaces to the CBX 500® switch. The ports provide trunk or user  
connections at data rates of 45 Mbps (DS3) or 34 Mbps (E3). You can use this module to provide  
high-density, high-speed ATM access services. You can also consolidate traffic from multiple  
access lines or from lower capacity multiservice switches for more cost-effective transport over a  
high-speed ATM multiservice backbone. The 8-Port DS3/E3 ATM module can help you reduce  
transport costs and increase revenue opportunities from high-density access services.
