Line Card Summary

Table 2-1 8-Port E3/DS3 ATM Line Card Summary

Product Number	Description	Minimum Cisco IOS Release
ESR-8E3DS3-ATM=	8-port E3/DS3 ATM line card	Initial Cisco IOS releases for PRE-2: 12.2(16)BX and later releases of Cisco IOS Release 12.2BX 12.2(28)SB and later releases of Cisco IOS Release 12.2(28)SB 12.3(7)XI and later releases of Cisco IOS Release 12.3XI For registered Cisco.com users, use Software Advisor to determine the software releases for this line card.

The 8-port E3/DS3 ATM line card has eight E3 or DS3 (T3) copper interface terminations that provide Asynchronous Transfer Mode (ATM) serial interfaces and perform Layer 2 ATM functions.

Each E3/DS3 interface port on the 8-port E3/DS3 ATM line card provides a single high-speed data channel.

•Maximum E3 bandwidth—34.386 Mbps

•Maximum DS3 bandwidth—44.736 Mbps

The 8-port E3/DS3 ATM line card can be used to:

•Provide eight E3 or DS3 trunk uplinks that support throughput of up to 44.736 Mbps at each port of the line card

•Provide IP packet routing over ATM virtual circuit connections using copper-based E3 or DS3 connectors at each port

•Operate as a subscriber interface card

The ATM features of the 8-port E3/DS3 ATM line card include:

•Broadband aggregation support for up to 8,000 simultaneously active, independent ATM virtual circuits per E3 or DS3 port, with a total limit of 32,000 VCs per line card

•Uses ATM cell header 8-bit virtual path identifiers (VPIs) and 16-bit virtual channel identifiers (VCIs)

•Provides ATM QoS (quality of service) management

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 card within a system are compatible, but does provide the minimum Cisco IOS requirements for individual hardware line cards, modules, or options.

Table 2-3 provides a description of the 8-port E3/DS3 ATM line card LEDs.

Table 2-3 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.
CARRIER (carrier detected)	Green	On	On when a carrier is detected at the corresponding port and the interface is operating properly.
		Off	Off when a loss of signal (LOS) is indicated.

Cables and Connectors

External network connections to the 8-port E3/DS3 ATM line card are made through the BNC connectors mounted on the rear of the Cisco 10000 chassis, using 75-ohm coaxial cable. The approved cables for use with the 8-port E3/DS3 ATM line card are cables conforming to WECO standards 728A, 734A, or 734D. Use cable lengths up to 450 ft (137.16 m). 735A cables can be used with lengths up to 225 ft (68.58 m).

Also see Appendix A, "Cisco 10005 Extender Card Information" for information about the extender card which must be used with the 8-port Unchannelized E3/T3 line card in the Cisco 10005 chassis.

All Cisco 10005 ESR cards connect to a backplane in the center of the chassis, and require extender cards to deliver the alarm, BITS clock, and DS3 signals to the rear of the chassis to make them accessible. The Cisco 10005 ESR alarm extender card and T3/E3 extender card extend and terminate these signals.

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