Revised: June 2008, OL-15863-01

1-Port Channelized OC-48 Line Card Overview

The 1-Port Channelized OC-48 line card is a single 2.488-Mbps (megabits per second) Optical Carrier-48 (OC-48) interface designed for Cisco XR 12000 series routers with Cisco IOS XR software installed on it. The 1-Port Channelized OC-48 line card interface can be channelized to DS3 or can be configured as a Packet-over-SONET (POS) interface. The line card supports only SONET framing and provides DS-3 aggregation for the Cisco XR 12000 series router. Table 1-1 lists the SONET channelization modes that are supported on the 1-Port Channelized OC-48 line card line card. The Cisco product number for 1-Port Channelized OC-48 line card is CHOC48/DS3-SR-SC=.

1-Port Channelized OC-48 Line Card Hardware and Software Compatibility

For successful installation and configuration of the 1-Port Channelized OC-48 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 1-Port Channelized OC-48 line card.

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 1-Port Channelized OC-48 line card.

Alphanumeric LEDs

The 1-Port Channelized OC-48 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.

1-Port Channelized OC-48 Line Card Interface Specifications

The physical layer interface for the channelized OC-48 line card is Optical Carrier-48 (OC-48, the specification for SONET STS-48c transmission rates). The channelized OC-48 line card is designed to support POS (Packet-over-SONET) or T3 mode, which results in the creation of a serial interface. By default, the controller comes up in 48xSTS-1 mode. The OC-48 line card provides a single 2.488-Mbps interface for all supported platforms.

Each channelized OC-48 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), Framerelay, or HDLC and is mapped into the STS-48c frame. (RFC 1619). The 1-Port Channelized OC-48 line card supports the SONET MIBs (RFC 3592, 2558), DS3/E3-MIB (RFC 2496), and MIB-2 (RFC 1213).
