Hardware Compression Module
End-of-Sale Announcement for NM-COMPR
Cisco Systems is announcing the End -of -Sale (EoS) for NM-COMPR (Hardware Compression network module) for the 3600 Series platforms. The major reasons for this decision are:
•The supplier of an Integrated Circuit (IC) which is key to the compression function has EoS'd (End of Sale'd) this IC.
•The sales volume of the NM-COMPR over its lifetime does not justify the major work to develop and test a replacement.
The recommended migration paths for customers requiring hardware compression is to the Cisco 3660 using the AIM-COMPR4. In contrast to the 2 T1/E1 - 4 Mbps fdx (approx. 8 Mbps aggregate) capability of the NM-COMPR, the AIM-COMPR4 supports 4 T1/E1 fdx (aggregate 16 Mbps). Since the 3660 can support 2 AIMS, the 3660 can scale to 32 Mbps of L2 compression. For 3620 customers that need a lower cost solution, the 2650 with the AIM-COMPR2 can be considered.
Because last-time buy purchases of specific EOL components have been made for the NM-COMPR, there is only a limited number of NM-COMPR's still available. Orderability of this product will only stay open until this inventory is depleted. At current run rate, the NM-COMPR inventory is expected to last until June, 2002.
The replacement products and support programs are detailed below. For those interfaces already deployed in the field, the standard Cisco support programs remain in effect.

Table 1: NM-COMPR EoS Schedule
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 will continue to support the NM-COMPR network module 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 two years and hardware support for a period of five years after the EoS date.

The AIN-COMPR4 provides the same compression services with 2x the throughput performance of the NM-COMPR modules. The minimum Cisco IOS release required for the hardware compression AIMS are as follows:

Key Benefits of Compression AIM's
•Maximizes System Resources
•Frees the platform's CPU for other routing tasks, improving performance
•Provides simultaneous support for multiple circuits
•Provides maximum compression performance where required
•Reduces packet traffic on a link when tariffing is usage based (resulting in WAN cost reduction)
•Shrinks frame lengths, allowing more data to be transmitted using the same amount of bandwidth and reducing the need for costly additional WAN links or circuits
•Enables customers to deploy additional services such as voice/data integration without increasing bandwidth
•Improves WAN Bandwidth Efficiency
•Maximizes WAN data throughput on all WAN interfaces (avoiding the expense of additional or higher-speed links)
•Improves application response time on congested links
•Maximizes the advanced bandwidth management capabilities of Cisco IOS
•Improves Branch-Office Network Manageability
•Eliminates costly external third-party products
•Single management view for platform and compression services
•Supports Industry Standards
•STAC (QIC122) compression algorithms
•Microsoft Point-to-Point Compression algorithm
•FRF.9 Frame Relay Payload Compression
•Compression Control Protocol (CCP) RFC
