2600 CE Module Content Engine Basic Performance 40GB Overview

Three 155-Mbps ATM OC-3 network modules are available on the Cisco 3620 and 3640 starting with Cisco IOS® Release 12.0(3)T. They are also now available on the Cisco 2691 and Cisco 3725 in starting in IOS release 12.2(13)T. These three network modules support STS-3c and STM-1 framing standards over multimode, single-mode intermediate-reach, and single-mode long-reach fiber optic interfaces. All three versions consist of a single-port network module with SC type connectors. The single-mode ATM network modules provide high-speed trunking for users with access to fiber WAN, while multimode is ideal for connecting high-speed servers, switches, or hubs equipped with and OC-3/STM-1 fiber connections.

All three versions support the ATM Forum standard ATM adaptation Layer 5 (AAL5) with ATM QoS categories Unspecified Bit Rate (UBR), UBR+, Variable Bit Rate (VBR)-rt, VBR-nrt, Available Bit Rate (ABR), and Constant Bit Rate (CBR) traffic classes support supported. Voice over IP (VoIP) and H.323 over ATM can be supported over the WAN using the currently available analog voice/fax network modules, and voice interface cards.

Three new Enhanced Performance (EP) ATM OC-3 network modules are released on Cisco 3745 to support the higher performance and better throughput. The ATM OC-3 EP network modules are identical to the Non-EP version in terms of features supported and physical specifications.

The ATM OC-3 network modules are supported on the Cisco 2691, 3620, 3640, 3660, and 3725 routers and the Enhanced Performance ATM OC-3 network modules are supported on Cisco 3745 router only. (Cisco 3745 does not support Non-EP ATM OC-3 network modules.) Cisco IOS "Plus" feature sets are required to support ATM. A maximum of one ATM OC-3 network module is recommended on Cisco 2691, 3600 Series and 3725. A maximum of two ATM OC-3 EP network module is recommended on Cisco 3745.
