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.

Table 1-3 provides a description of the 4-port OC-3/STM-1 ATM line card LEDs.

Table 1-3 LED Description

LED Label	Color	State	Meaning
FAIL	Yellow	Off	Off when line card is working properly. Turns on for a few seconds during line card power-on self test (POST), then turns off when the line card is working properly.
		On	On when the line card POST fails.
LOOP	Yellow	Off	Off when the line card is available for normal operation.
		On	On when some portion of the corresponding port data is in a loopback state and is not available for normal operations.
ALARM	Yellow	Off	Off when the line card is operating normally.
		On	On when an alarm condition exists at the corresponding port.
CD (carrier detected)	Green	On	On when a carrier is detected at the corresponding port.
		Off	Off when a loss of signal (LOS) is indicated.

Cables and Connectors

Table 1-5 provides optical cable specifications for the line card.

Table 1-5 Optical Specifications

Transceiver Type	Transmit Power	Maximum Power to Receiver	Minimum Receiver Sensitivity	Nominal Distance Between Stations	Wavelength	Fiber Type: Single Mode
Single-mode intermediate reach	-15 dBm minimum to -8 dBm maximum	-8 dBm	-28 dBm	Up to 9 mi (15 km)	1280 nm to 1335 nm	Core size 8 to 10 microns
Single-mode long reach (LR)	-5 dBm minimum to 0 dBm maximum	-10 dBm1	-34 dBm	Up to 25 mi (40 km)	1280 nm to 1335 nm	Core size 8 to 10 microns

1 For LR, a minimum of 10 dB of total attenuation between transmitter and receiver is required. Exceeding the maximum receive power can damage the optics.

Go to Chapter 16, "Preparing for Installation" to begin the installation or replacement of the line card.
