Chapter 1 4-Port OC-3/STM-1 ATM Line Card Overview
Software and Hardware Compatibility
The 4-port OC-3/STM-1 ATM line card is a NEBS-compliant device that performs Layer 2
Asynchronous Transfer Mode (ATM) functions. This line card receives and transmits ATM cells on each
network physical interface connected to a line card port, and simultaneously transmits and receives
packets from the Cisco 10000 series router backplane.
This line card can be used to:
• Provide four OC-3 trunk uplinks
• Provide IP packet routing over ATM virtual circuit connections using single-mode fiber
intermediate reach and long reach LC connectors at each port
• Operate as a subscriber interface card
The 4-port OC-3/STM-1 ATM line card is an implementation of ATM over SONET switching. This line
card supports the following features:
• Conforms to the ATM forum ATM UNI 3.1 155.52-Mbps physical layer specification
• Uses ATM cell header 8-bit virtual path identifiers (VPIs) and 16-bit virtual channel identifiers
(VCIs)
• Provides ATM QoS (quality of service) management
• Complies with the SONET/SDH OC-3 STS-3/STM-1 framing format
• Accommodates SONET overhead bits
• Provides up to 8191 total connections
• Provides alarm processing
• Provides continuous performance monitoring

Software and Hardware Compatibility
To check the minimum software requirements of Cisco IOS software with the hardware installed on your
router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether line
cards within a system are compatible, but does provide the minimum Cisco IOS requirements for
individual hardware line cards, modules, or options.
Note Access to this tool is limited to users with Cisco.com login accounts.
To access Software Advisor, click Login at Cisco.com, type “Software Advisor” in the SEARCH box,
