Line Card Summary

Table 14-1 1-Port OC-48/STM-16 Packet over SONET Line Card Summary

Product Number	Description	Minimum Cisco IOS Release
ESR1OC48/P/SRPSMS=	1-port OC-48/STM-16 POS/SRP, single-mode, short-reach line card	Initial Cisco IOS releases for PRE-2: 12.2(15)BX and later releases 12.2(28)SB and later releases of Cisco IOS Release 12.2(28)SB 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 12.3XI For registered Cisco.com users, use Software Advisor to determine the software releases for this line card.
ESR1OC48/P/SRPSML=	1-port OC-48/STM-16 POS/SRP, single-mode, long-reach line card

The 1-port OC-48/STM-16 Packet over SONET line card provides a trunk uplink capable of supporting up to 2.4 Gbps full duplex throughput over a standard SONET/ITU-T Synchronous Digital Hierarchy (SDH) interface, using a single-mode fiber with SC connectors.

Figure 14-1 shows the front panel of the OC-48/STM-16 Packet over SONET line card.

The 1-port OC-48/STM-16 Packet over SONET line card provides a point-to-point connection to a backbone router and encapsulates IP packets with byte-wise HDLC framing, placing them directly into the OC-48 SONET (or SDH) payload.

The 1-port OC-48/STM-16 Packet over SONET line card is a standard implementation of Packet over SONET switching, and supports the following features:

•OC-48 bandwidth between the line card and the Performance Routing Engine (PRE)

•North American (SONET) and European (SDH) formats

•Automatic protection switching (APS)

•Alarm processing

•Performance monitoring

•IP over DCC (Data Communications Protocol) for remote management of the Cisco 15104 OC-48/STM16 Optical Regenerator, where applicable

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.

Cables and Connectors

The1-port OC-48/STM-16 Packet over SONET line card uses a single- mode fiber-optic cable with SC-type connectors.

---

Warning The long reach version of the 1-port OC-48/STM-16 Packet over SONET line card (product number ESR1OC48/P/SRP-SML) requires a minimum optical attenuation to avoid irreversible damage to the receiver.

---

Table 14-5 lists optical cabling specifications for the 1-port OC-48/STM-16 Packet over SONET line card.

Table 14-5 Optical Specifications

Transceiver Type	Transmit Power	Maximum Power to Receiver	Minimum Receiver Sensitivity	Nominal Distance Between Stations	Wavelength	Fiber Type
OC-48 POS short reach	-10 dBm minimum to -3 dBm maximum	-3 dBm	-18 dBm	Up to 1.24 mi (2 km)	1266 nm to 1360 nm	Single mode, core size 8 to 10 microns
OC-48 POS long reach 2 (LR2)	-2 dBm minimum to +3 dBm maximum	-9 dBm1	-28 dBm	Up to 50 mi (80 km)	1500 nm to 1580 nm	Single mode, core size 8 to 10 microns

1 For LR2, a minimum of 12 dB of total attenuation between transmitter and receiver is required. Exceeding the maximum receive power can damage the optics.

Go to Chapter 16, "Preparing for Installation" to begin the installation or replacement of the line card.
