ATM Over MPLS
ATM Services Configuration Guide for CBX 3500, CBX 500, GX 550, and B-STDX 9000 1/19/051-3
ATM Over MPLS
Chapter 8 describes how to configure ATM over MPLS trunks between Lucent ATM 
switches and Juniper T-series (T-640 and T-320) routers running JUNOS.
Chapter 9 describes how to configure additional ATM over MPLS applications for the 
CBX 3500 edge switch, including using Layer 2 tunnels and Pseudo Wires to send 
traffic over the MPLS core network. 
PVCs
Chapter 10 describes how to configure point-to-point, redirect, and 
point-to-multipoint (PMP) PVCs. 
Chapter 11 explains how to configure optional Management VPI/VCI, Management 
PVC, and Management SPVC connections. 
Network-wide Features
The following chapters explain how to configure features that you can use throughout 
your ATM network. 
• Chapter 12 describes how the CBX 3500, CBX 500, and GX 550 use traffic 
descriptors to define a service contract that guarantees that a specified amount of 
data is delivered. You configure a set of traffic descriptors that you can use when 
you define PVCs throughout your ATM network; this configurable control circuit 
feature enables you to ensure Quality of Service (QoS). Note that ATM services 
for a B-STDX 9000 switch, CBX 500 frame-based modules, and 4-port ethernet 
modules do not use traffic descriptors.
• Chapter 13 describes a Layer2 Virtual Private Network (VPN) which is an 
optional software feature that enables network providers to dedicate resources for 
those customers who require guaranteed performance, reliability, and privacy. Use 
the instructions in this chapter to configure Layer2 VPN services.
