Line Card Summary

Table 8-1 6-Port Channelized T3 Line Card Summary

Product Number	Description	Minimum Cisco IOS Release
ESR-6CT3=	6-port channelized T3 line card	Initial Cisco IOS releases for PRE-1: 12.0(9)SL and later releases of Cisco IOS 12.0SL 12.0(17)ST and later releases of Cisco IOS 12.0ST 12.0(22)S and later releases of Cisco IOS 12.0S 12.2(8)BZ and later releases of Cisco IOS 12.2BZ Initial Cisco IOS releases for PRE-2: 12.2(15)BX and later releases of Cisco IOS 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 12. XI For registered Cisco.com users, use Software Advisor to determine the software releases for this line card.

The 6-port channelized T3 line card provides the Cisco 10000 series routers with six DS3 ports of high-density T3 service.

The Cisco 10008 router can support up to seven channelized T3 line cards, with a maximum capacity of 42 T3 connections or 1176 T1 connections per chassis. A fully loaded 7-foot rack can support up to 126 T3 connections, or 3528 T1 connections. This configuration assumes at least one slot is used for an uplink.

•You can channelize the T3 line into 28 independent DS1 data channels. You can channelize DS1 channels down to DS0 time slots (56 kbps or 64 kbps) with a maximum of 128 channels per DS3.

•Alternatively, the T3 line may supply some or all of the T3 payload (full-rate DS3) to a single end user.

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 8-2 lists router model, line card, and processor compatibility.

Table 8-2 Line Card, Router, and Processor Compatibility

Line Card	Cisco 10008	Cisco 10005	PRE-2	PRE-1	PRE
6-port channelized T3 line card	Yes	Yes	Yes	Yes	Yes

---

Note If you are using the 6-port channelized T3 line card with a Cisco 10005 router, you must use the Cisco 10005 extender card. See Appendix A, "Cisco 10005 Extender Card Information" for more information on the extender card.

Table 8-3 provides a description of the 6-port channelized T3 line card LEDs.

Table 8-3 LEDs Description

LED Label	Color	State	Meaning
FAIL	Yellow	Off	Off when line card is working properly.
		On	A major failure has disabled the line card.
LOOP	Yellow	Off	Port is in a loopback state and not enabled for data traffic.
		On	On when some portion of the corresponding port data is in a loopback state (T3 or T1) and is not enabled for data traffic.
ALARM	Yellow	Off	Off when there is no alarm condition.
		On	On when an alarm condition (T3 or T1) exists at DS1, AIS, DS1 remote, DS1 OOF, DSE OOF, DSE AIS, or DS3 FERF 1 level.
CARRIER (carrier detected)	Green	Off	No carrier is detected; the port is not able to pass traffic.
		On	On when a carrier is detected; the port is able to pass traffic.

Cables and Connectors

External network connections to the 6-port channelized T3 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 6-port channelized T3 line card are cables conforming to WECO standards 728A, 734A, or 734D. Use cable lengths up to 900 ft (274.32 m). 735A cables can be used with lengths up to 225 ft (68.58 m).

See Figure 8-4 for the BNC connectors on the rear of the Cisco 10008 router, and Figure 8-5 for the BNC connectors on the rear of the Cisco 10005 router.

Also see Appendix A, "Cisco 10005 Extender Card Information" for information about the extender card which must be used with the 6-port channelized T3 line card in the Cisco 10005 chassis.

All Cisco 10005 line 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.

For troubleshooting information, see Chapter 18, "Troubleshooting the Installation."
