Chapter 1 Overview Features Despite the name, SONET is not limited to optical links. Electrical specifications have been defined for CATV 75-ohm coaxial cable. Transmission rates are integer multiples of 51.840 Mbps, which can be used to carry T3/E3 bit-synchronous signals. The following transmission multiples are currently specified and commonly used: • STS-3c—155.520 Mbps • STS-12c—622.080 Mbps (the OC12 POS line card conforms to STS-12c) • STS-48c—2.
Chapter 1 Overview OC12 POS Line Card Optical Fiber Specifications Each OC12 POS line card has one pair of SC-type fiber receptacles to allow connection to single-mode optical fiber. (For more information on the optical fiber cables you should use with this line card, see the “OC12 POS Line Card Optical Fiber Specifications” section on page 1-5 and the “Cables and Connectors” section on page 1-8.) Packet data is transported using Point-to-Point Protocol (PPP) and is mapped into the STS-12c/STM-4 frame.
Chapter 1 Overview LEDs To calculate link losses and dispersion losses for your application, refer to the following specifications and documents: • EIA/TIA-IVa Dispersion Unshifted Single-Mode Fiber • EIA/TIA-IVb Dispersion Shifted Single-Mode Fiber • GR-20-CORE Generic Requirements for Optical Fiber and Fiber-Optic Cable • ITU-T Recommendation G.

Chapter 2 Preparing for Installation Safety Guidelines Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
Chapter 2 Preparing for Installation Safety Guidelines Aviso Este símbolo de aviso indica perigo. Encontra-se numa situação que lhe poderá causar danos físicos. Antes de começar a trabalhar com qualquer equipamento, familiarize-se com os perigos relacionados com circuitos eléctricos, e com quaisquer práticas comuns que possam prevenir possíveis acidentes.
Chapter 2 Preparing for Installation Safety Guidelines Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Line cards and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier.
Chapter 2 Preparing for Installation FCC Class A Compliance FCC Class A Compliance This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
C H A P T E R 3 Removing and Installing Line Cards This chapter describes how to remove the OC12 POS line card from its supported platform, how to install a new or replacement line card, and how to connect cables.
Chapter 3 Removing and Installing Line Cards Handling Line Cards Handling Line Cards Caution Always handle the line card by the carrier edges and handle; never touch the line card components or connector pins. (See Figure 3-1.
Chapter 3 Removing and Installing Line Cards Line Card Removal and Installation Caution To prevent jamming the carrier between the upper and the lower edges of the slot, and to ensure that the connector at the rear of the line card mates with the connection at the rear of the slot, make certain that the carrier is positioned correctly, as shown in the cutaway in the following illustration.
Chapter 3 Removing and Installing Line Cards Line Card Removal and Installation Cisco 7304—Removing and Installing a Line Card 1. To remove the line card, loosen the locking thumbscrews on both sides of the line card. 2. Pull out the line card levers and carefully slide the line card halfway out of the slot. If you are removing a blank line card, pull the blank line card completely out of the chassis slot. 3. With the line card halfway out of the slot, disconnect all cables from the line card.
Chapter 3 Removing and Installing Line Cards Connecting OC12 POS Line Card Interface Cables Connecting OC12 POS Line Card Interface Cables To continue your OC12 POS line card installation, you must connect the interface cables. Note Optical fiber cables are not available from Cisco Systems; they are available from outside commercial cable vendors.

C H A P T E R 4 Configuring the OC12 POS Line Card To continue your OC12 POS line card installation, you must configure the OC-12 interface.
Chapter 4 Configuring the OC12 POS Line Card Configuring the Interfaces Configuring the Interfaces After you verify that the new OC12 POS line card is installed correctly (the STATUS LED goes on), use the privileged-level configure command to configure the new interface.
Chapter 4 Configuring the OC12 POS Line Card Configuring the Interfaces Performing a Basic Configuration This section describes the procedures for performing a basic configuration: enabling an interface (with the no shutdown command) and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration and the protocols you plan to route on the interface.
Chapter 4 Configuring the OC12 POS Line Card Configuring the Interfaces Step 6 After including all of the configuration subcommands to complete your configuration, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt. Step 7 Write the new configuration to NVRAM as follows: Router# copy running-config startup-config [OK] Router# This completes the procedure for creating a basic configuration.
Chapter 4 Configuring the OC12 POS Line Card Configuring the Interfaces Configuring Framing The default framing setting is SONET. To configure for SDH, enter the pos framing-sdh command: Router(config)# interface pos 3/1 Router(config-if)# pos framing sdh To change back to SONET, enter the no pos framing sdh command.
Chapter 4 Configuring the OC12 POS Line Card Configuring the Interfaces To verify that SONET payload scrambling is enabled on an interface, enter the show running-config command. If scrambling is enabled, the following line is displayed in the configuration: pos scramble-atm To disable SONET payload scrambling, use the no pos scramble-atm command. Configuring SONET Delay Triggers A trigger is an alarm that, when asserted, causes the line protocol to go down.
Chapter 4 Configuring the OC12 POS Line Card Checking the Configuration Checking the Configuration After configuring the new interface, use the show commands to display the status of the new interface or all interfaces, and use the ping command to check connectivity.

Chapter 4 Configuring the OC12 POS Line Card OC12 POS Statistics Counters Configuring an Interface for Internal Loopback The default loopback setting is for no loopback. With internal (or local) loopback, packets from the router are looped back in the framer. Outgoing data gets looped back to the receiver without actually being transmitted. Internal loopback is useful for checking that the OC12 POS line card is working.

To contact the TAC, see the “Obtaining Technical Assistance” section on page ix. CLI-Controlled OIR Line cards can be removed from the Cisco 7304 router without disrupting data flow by using the hw-module slot slot # stop/start command in EXEC mode.
