ATM Connections
This chapter describes how ATM connection services are established by adding ATM connections
between ATM service interface ports in the network using ATM standard UNI 3.1 and Traffic
Management 4.0. It describes BXM and ASI card operation and summarizes ATM connection
parameter configuration
The chapter contains the following:
• ATM Connection Services
• SVCs
• Traffic Management Overview
• ATM Connection Requirements
• ATM Connection Configuration
• Traffic Policing Examples
• Traffic Shaping for CBR, VBR, and UBR
• LMI and ILMI Parameters
ATM Connection Services
ATM connection services are established by adding ATM connections between ATM service
interface ports in the network. ATM connections can originate and terminate on the ASI (ATM
Service Interface) cards, on BXM-T3/E3, BXM-155 (OC-3), and BXM-622 (OC-12) cards
configured for port (service access) operation on the BPX switch, or on the MGX 8220 (using the
AUSM card for the MGX 8220). Frame relay to ATM network interworking connections are
supported between either BXM or ASI cards to the IPX, IGX, or MGX 8220. Frame relay to ATM
service interworking connections are supported between either BXM or ASI cards to FRSM cards
on the MGX 8220.
Figure 7-1 is a depiction of ATM connections over a BPX switch network. It shows ATM
connections via BXM-T3/E3, BXM-155, BXM-622, ASI-1, and ASI-155 cards, as well as over
MGX 8220 switches. It also shows frame relay to ATM interworking connections over the MGX
8220, IPX, and IGX shelves. For further information on the MGX 8220, refer to the MGX 8220
Reference document.
