Configuring ATM Logical Ports on
Frame-based Modules
This chapter describes how to configure logical ports for ATM services on
B-STDX 9000 and CBX 500 FR-based modules. Most I/O modules (IOMs) in the
B-STDX 9000 perform a type of “frame-based” ATM switching. The 1-port ATM CS
DS3/E3 and 1-port ATM IWU OC-3c/STM-1 modules are capable of performing
ATM cell-switching. Keep in mind that the dialog boxes that appear while you
configure logical ports display different attributes depending on the type of frame- or
cell-based module being configured.
The CBX 500 frame-based modules are also capable of providing frame-based ATM
switching. ATM logical ports for these modules are configured the same as a
B-STDX 9000 frame-based module.
For information about the basic elements of ATM service, see one of the following
sections in Chapter 2, “About ATM Logical Ports”:
• “Using ILMI” on page 2-5
• “VPs and VCs” on page 2-12
• “About the Oversubscription Factor” on page 2-19
