Line Card Summary

Table 15-1 8-Port Unchannelized E3/T3 Line Card Summary

Product Number	Description	Minimum Cisco IOS Release
ESR-8E3/DS3=	8-port unchannelized E3/T3 line card	Initial Cisco IOS releases for PRE-1: 12.0(22)S and later releases of Cisco IOS 12.0S Initial Cisco IOS releases for PRE-2: 12.0(22)S and later releases of Cisco IOS 12.0S 12.0(20)ST and later releases of 12.0ST 12.3(7)XI and later releases of Cisco IOS 12.3XI For registered Cisco.com users, use Software Advisor to determine the software releases for this line card.

In unchannelized (also called clear channel) operation, each E3/T3 interface port provides a single high-speed data channel. Each port can be configured to use any portion of the E3/T3 available bandwidths. The maximum E3 bandwidth is 34.386 Mbps; the maximum T3 bandwidth is 44.736 Mbps.

The line card provides Cisco 10000 series routers with eight E3 or T3 high-density unchannelized interface ports. The line card:

•Supports eight multiport T3 or E3 copper interface terminations

•Provides a solution for service providers if a fiber interface is unavailable

•Provides Internet service providers with the means to interface with existing copper Internet Protocol (IP) leased-lines

•Supports the High-Level Data Link Control (HDLC), Frame Relay, and Point-to-Point Protocol (PPP) encapsulations

If you are a registered Cisco.com user, see Feature Navigator for supported features.

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.

Line Card, Router, and Processor Compatibility

Table 15-2 lists router model, line card, and processor compatibility.

Table 15-2 Line Card, Router, and Processor Compatibility

Line Card	Cisco 10008	Cisco 10005	PRE-2	PRE-1	PRE
8-port unchannelized E3/T3 line card	Yes	Yes	Yes	Yes	No

---

Note The 8-port unchannelized E3/T3 line card has been compliance-tested to function in a Cisco 10005 chassis.

Table 15-3 provides a description of the 8-port unchannelized E3/T3 line card LEDs.

Table 15-3 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. Off if the card power supply fails. Off if the card 48V fuse is blown. On when the line card POST fails.
		On	On if a failure occurs.
		Blinking	Blinking under certain POST failures.
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 unchannelized E3/T3 line card are made through the BNC connectors mounted on the rear of the Cisco 10000 chassis, using 75-ohm coaxial cable (Figure 15-4). The approved cables for use with the 8-port unchannelized E3/T3 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 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 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.
