SUPPORT

End of sale refers to the time when certain products are no longer available for new purchases. It does not apply to the service and support programs for those products. Cisco systems will continue to support the PA-A1 ATM port adapter through our SMARTnet and comprehensive maintenance programs. Customers with either of these service contracts are entitled to free software updates, 24-hour phone support through the Technical Assistance Center, and advanced replacement of hardware for repairs. Comprehensive maintenance customers also receive onsite service. Customers who do not have a maintenance contract can purchase software updates and hardware repair services from Cisco to meet specific requirements rather than full-service coverage. Cisco is committed to providing software support for a minimum of three (3) years and providing hardware support for a period of five (5) years after the EOS date.

PRODUCT SUBSTITUTION

The Cisco Technology Migration Program (TMP) incorporates generous trade-in credits for the ATM port adapter (PA-A1) toward the enhanced ATM port adapter (PA-A3).

The PA-A3 enhanced ATM port adapter introduces many new ATM hardware and software features. Its comprehensive ATM feature set includes per-VC traffic shaping, support for many ATM Services Classes (nrt-VBR, ABR, and UBR), a new high-performance SAR architecture and support for a very large number of ATM virtual connections (VC). All of these features are based on industry specifications and standards.
