4-Port Channelized OC-12 Line Card Overview

The 4-Port Channelized OC-12/STM-4 ISE line card provides Cisco XR 12000 Series Routers with four OC-12c/STM-4c ports that can be channelized to DS3/E3, OC-3c/STM-1c, or OC-12c/STM-4c. The line card supports both SONET and SDH framing and provides DS-3/E3 aggregation for the Cisco XR 12000 Series Router. For SDH, both AU-3 and AU-4 mappings are supported. Table 1-1 lists the mappings and channelization that are supported on the 4-Port Channelized OC-12/STM-4 ISE Line Card.

Table 1-1 Supported SONET and SDH Channelization Modes
SONET Channelization	SDH-AU3 Channelization	SDH-AU4 Channelization
STS-12c	STM-4, AU4-4-4c	STM-4
STS-3c	STM-1, AU4	STM-1
STS-1:DS-3¹	STM-1 and AU3:VC-3:DS-3/E3	STM-1 and AU4:TUG-3:VC3:DS-3/E3

¹All valid combinations of these modes are supported

The line card interfaces with the Cisco XR 12000 Series Router switch fabric and provides a full-duplex short cable (SC), single-mode, intermediate-reach optical interface. Figure 1-1 shows the front view of this line card.

4-Port Channelized OC-12 Line Card Hardware and Software Compatibility

For successful installation and configuration of the 4-Port Channelized OC-12 line card, ensure that the compatible hardware and the Cisco IOS XR Software Release are installed. This section provides details regarding the compatible Cisco IOS XR Software Release and the hardware revision requirements.

Cisco IOS XR Software Release Requirements

Table 1-6 lists the Cisco IOS XR software release that is compatible with the 4-Port Channelized OC-12 line card.

Table 1-6 4-Port Channelized OC-12 line card and IOS XR Software Release Compatibility
Channelized Line Card	Cisco IOS XR Software Release
4-Port Channelized OC-12 Line Card	Cisco IOS XR Software Release 3.8.0

Hardware Revision Requirements

To ensure compatibility with the software, your channelized line card should have a specific hardware revision number. The number is printed on a label affixed to the component side of the card. The hardware revision number can be displayed by using the show diag 0/1/cpu0 command.

Table 1-7 lists the hardware revision number for the 4-Port Channelized OC-12 Line Card.

Table 1-7 4-Port Channelized OC-12 line card Hardware Revision Requirements
Channelized Line Card	Minimum Hardware Revision Number
4-Port Channelized OC-12/STM-16 ISE	73-7397-yy (where yy is a number from 01 to 14)	800-18816-xx (where xx is a number from 01 to 10)

4-Port Channelized OC-12 Line Card LEDs

See Figure 1-1 for the location of the LEDs on the 4-Port Channelized OC-12 line card. The different operating states of the status LEDs are shown in Table 1-8.

Table 1-8 4-Port Channelized OC-12 Line Card Status LED Descriptions
LED	Color/Activity	Description
Active	Off	Port is administratively down, or diagnostics are running.
Active	Solid Green	Port is administratively up.
Carrier	Off	Port is operationally down.
Carrier	Solid Green	Port is up and frames are received.
Rx PKT	Blinking Green	Line card is receiving data.

Alphanumeric LEDs

The 4-Port Channelized OC-12 Line Cards have two four-digit alphanumeric LED displays at one end of the faceplate (near the ejector lever) that display a sequence of messages indicating the state of the card. In general, the LEDs do not come on until the route processor (RP) recognizes and powers up the card. As it boots, the line card displays a sequence of messages similar to those in Table 1-9.

Note Some messages might appear in brief and for a short time. Also, some messages listed in Table 1-9 may not appear on your line card.

4-Port Channelized OC-12 Line Card Interface Specifications

The physical layer interface for the channelized OC-12 line card is Optical Carrier-12 (OC-12, the specification for SONET STS-12c transmission rates). The channelized OC-12 line card is designed to support both SONET and SDH mode of operation. In SONET mode, the OC-12 port can be channelized to carry STS-12c, STS-3c, STS1:DS3, or a combination of STS-3c and STS-1:DS3. In SDH mode, AU4 and AU3 are supported. By default, the controller comes up in 12xSTS-1 mode. The OC-12 line card provides a single 2.488-Mbps interface for all supported platforms.

Each channelized OC-12 line card has one pair of short cable (SC) type fiber receptacles to allow connection to single-mode optical fiber. Packet data is transported using Point-to-Point Protocol (PPP), Frame Relay, or HDLC and is mapped into the STS-12c frame (RFC 1619). The 4-Port Channelized OC-12 Line Card supports the following MIBs:

•CISCO-ENTITY-ASSET-MIB

•CISCO-ENTITY-SENSOR-MIB

•CISCO-SONET-MIB

•CISCO-ENTITY-VENDORTYPE-OID-MIB

•DS3/E3-MIB (RFC 2496)

•ENTITY-MIB

•FR DTE MIB

•IF-MIB (RFC 2863)

•MIB-2 (RFC 1213)

•SONET MIBs (RFC 3592, 2558)
