ATM FCP Attributes
Cascade Communications Resource Management (CCRM) cells are a subset of the
ATM Forum’s ATM Traffic Management, Version 4.0, ABR resource management
(RM) cells. The backward congestion message (BCM) cells provide interoperability
with other manufacturers’ ATM switches.
For information about basic concepts, configuration procedures, and frequently-asked
questions for the ATM FCP, see the following chapters in this guide:
• Chapter 5, “About the ATM FCP,” describes the operation of the ATM FCP.
• Chapter 6, “Working with the ATM FCP,” provides detailed configuration
procedures and answers to frequently-asked questions about using the ATM FCP.
• Appendix D, “ATM FCP Rate Profile Tables,” describes the organization and
default values for the ATM FCP rate profile tables.
If this is a UNI logical port, continue with “Configuring Logical Ports for Use With
ATM SVCs” on page 3-59. If this is an NNI logical port, proceed to “Completing the
Logical Port Configuration” on page 3-57.
Note – Contact a qualified Lucent organization for network design validation before
