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.
Applications
• Provide high-density, high-speed
ATM access
• Consolidate low-speed ATM
access services
Features
• High port density — up to 112
DS3/E3s per switch
• Independent logical port
configuration
• Signaling support for 3,000 new
VCs per second
• All ports operate at line speed
• Generous port and switch cell
buffers ensure data integrity
• Optional Flow Control Processor
ensures network fairness and QoS
• Hot swappable
Benefits
• Deliver the flexibility, QoS support, and performance required for high-
speed multiservice networking
• Increase revenue potential by offering high-density services from a
compact chassis
• Concentrate large volumes of high-speed ATM traffic cost-effectively
• Reduce operating costs and simplify network management with Navis
