Line Card Summary

Table 7-1 4-Port Channelized OC-3/STM-1 Line Card Summary

Product Number	Description	Minimum Cisco IOS Release
ESR-4OC3-ChSTM-1/OC-3=	Cisco 10000 series 4-port channelized OC-3/STM-1 (DS3/E1/DS1/DS0) SDH line card	Initial Cisco IOS releases for PRE-1: 12.0(15)SL and later releases of 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 for SDH mode. For both SONET and SDH mode, use Cisco IOS Release 12.0(23)S and later releases of Cisco IOS 12.0S. Initial Cisco IOS Releases for PRE-2: 12.3(7)XI and later releases of Cisco IOS 12.3XI For both SONET and SDH mode, the use Cisco IOS Release 12.2(15)BX and later releases of Cisco IOS 12.2BX. Cisco IOS Release 12.2(28)SB and later releases of Cisco IOS Release 12.2(28)SB For registered Cisco.com users, use Software Advisor to determine the software releases for this line card.

The 4-port channelized OC-3/STM-1 line card uses fractional T1 (n x DS0), DS-1, E1, fractional E1
(n x DS0) and DS3 IP services to connect ISP customers to the network backbone. It provides full duplex operation at OC-3 bandwidth rates using a (single-mode) fiber optic port that provides the Cisco 10000 series router with one interface that connects up to 768 individual channelized options.

The 4-port channelized OC-3/STM-1 line card has four single-mode, intermediate-reach LC OC-3/STM-1 duplex optical connectors.

The line card can be configured into either SONET or SDH mode.

•When configured for SONET mode, each OC-3 port carries three DS3 (full rate, subrate, or channelized down to DS1) channels, or 84 individual DS1s, each capable of carrying a single channel at full or fractional rates.

•When configured for SDH mode, each STM-1 port carries three DS3 (full rate, subrate, or channelized) channels, 84 individual DS1s, or 63 individual E1s; each DS1/E1 is capable of carrying a single channel at full or fractional rates. The line card runs in either E1 or T1 mode, but no mixture of T1/E1 is supported.

Each STM-1 port supports up to 192 channels, for a total of 768 channels per line card. The total number of channels cannot exceed the chassis scaling limits.

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 7-2 shows the router model, line card, and processor compatibility.

Table 7-2 Line Card, Router, and Processor Compatibility

Line Card	Cisco 10008	Cisco 10005	PRE-2	PRE-1	PRE
4-port channelized OC-3/STM-1 line card	Yes	Yes	Yes	Yes	Yes

LEDs

The 4-port channelized OC-3/STM-1 line card LEDs are shown in Figure 7-1.

Figure 7-1 4-Port Channelized OC-3/STM-1 Line Card Faceplate Description

1	Fail LED	5	Ports 0-3 (TX in this illustration is to the left and RX to the right for each port. When inserted, TX is on top, RX on the bottom.)
2	Loop LED (ports 0 and 1)	6	Loop LED (ports 2 and 3)
3	Alarm LED (ports 0 and 1)	7	Alarm LED (ports 2 and 3)
4	CD (carrier detect) LED (ports 0 and 1)	8	CD (carrier detect) LED (ports 2 and 3)

Table 7-3 provides a description of the 4-port channelized OC-3/STM-1 line card LEDs.

Table 7-3 LEDs 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	Green	Off	Off when the line card is available for normal operation.
		On	On when one or more DS1/E1, DS3, or SONET subports on this port are looped back and cannot carry data traffic. Use the no loopback command to disable the loop.
ALARM	Green	Off	Off when the line card is operating normally.
		On	On when an alarm condition exists at the corresponding port. Use the show facility-alarm status command to display more information about the alarm condition.
CD (carrier detected)	Green	Off	No carrier is detected—this port is not able to pass traffic.
		On	On when a carrier is detected at the corresponding port and the port is properly configured to pass traffic.
