Product Bulletin No. 682

Cisco Channelized DS3 Interface Processor Model 20 End of Sale


This product bulletin covers the issues associated with the end of sale of the Channelized DS3 Interface Processor Model 20 (CT3IP-20) product and the appropriate upgrade product.

The last order date for this product is January 29, 1998. The last order date has been accelerated because of the price reduction of the existing CT3IP-40. The CT3IP-40 product is a form, fit, and function replacement for the CT3IP-20. Information about products affected by this announcement, product availability, maintenance, and product substitutions are included.


The CT3IP product family is based on the Versatile Interface Processor 2 (VIP2) product family. The VIP2 family has been streamlined to simplify product selection, remove many configuration limitations, and collapse distributed switching and distributed services features into a single product offering. These same changes are being propagated to the CT3IP family.


CT3IP-20 has entered end of sales with the recent decision to combine the distributed services capability of the CT3IP-40 with the distributed switching capability of the CT3IP-20. The price of the CT3IP-40 has been reduced to the level of the CT3IP-20 concurrent with this end of sales announcement.

The last order date for the CT3IP-20 has been accelerated since the CT3IP-40 is a direct replacement at the same price point and has additional memory and increased capabilities.
