Data Sheet


Cisco 3600 Series ATM 25 Network Module (NM-1ATM-25)


The Cisco 3600 platform with the new ATM 25 Network Module offers high-performance branch office access. The Network Module is designed primarily to allow branch office to take advantage of new high speed leading edge ADSL connection technology. The Network Module can also function as part of an ATM 25 network environment. This new network module, part of Cisco's broad portfolio of CPE and CO DSL products, compliments the current range of over 30 network modules now available for the Cisco 3600 series.


Figure 1   ATM 25 Network Module and Cisco 3600

The 25.6-Mbps ATM NM is ideal for the termination of cost-effective ADSL connections. Managers can cost- effectively deploy ATM all the way to the 3600, allowing for support of applications on the branch office LAN such as videoconferencing, videosurveillance, distance learning, Voice over data, or videobroadcast applications.


Figure 2   Targeted ATM 25 Network Module Applications

In Figure 1, a branch office Cisco 3620 or Cisco 3460 with the NM-1ATM-25 installed, connects to an external ADSL modem (CAP or DMT) to provide connection through an ADSL cloud to the branch office HQ.

Connection speeds from the HQ can be up to 8Mb/s, and to the branch, connection speeds of up to 1Mb/s are available. The actual connection speeds are related to the type of DSL equipment being utilized, the type of service used, and the distance from the branch office to the DSLAM.

Physical Characteristics

The ATM Network Module has one ATM User- Network Interface (UNI) port, each with a standard throughput rate of 26.5 Mbps full duplex. The ATM NM is compatible with the ATM Forum 25.6-Mbps physical sublayer (PHY) specification for unshielded twisted-pair (UTP), Category 3 (UTP-3), or shielded twisted-pair (STP) cable plants.

The NM-1ATM-25 network module is supported in both the 3620 and 3640 platforms. One ATM Network Module is supported in the 3620, and two ATM Network Modules are supported on the 3640.

The ATM Network Module requires any of the "Plus" versions of the Cisco IOS® 11.3(3a)T.
