BATM Switch Feature Interactions

Location-related Interactions

B-1

ATM Switch Feature InteractionsB

The interconnection of port networks across a wide area through multiple ATM switches may introduce delays in establishing some inter-port network connections. WAN interconnectivity can introduce some transmission delays.

The following topics are covered in this appendix.

■Location-related Interactions

■Features Supported

■Features Not Supported

■Delay Interactions

■ATM Feature Interactions

■Cross-product Compatibility

Location-related Interactions

Location-related problems happen in two areas:

■Switch operability

■Feature performance

Switch operability

The basic switch functions (Table B-1) are affected by location within the ATM application.
