Feature Overview
The Cisco uBR10 Spatial Reuse Protocol (SRP) OC12 single-mode fiber, long reach (SML) dynamic packet transport (DPT) WAN line card provides shared IP over SONET capability for the Cisco uBR10012 router platform.
The Cisco uBR10-SRP-OC12SML DPT WAN line card:
•Accommodates large scale network topology.
The WAN card is deployed in SONET OC-12 DPT rings. The DPT rings are connected to SONET Add Drop Multiplexers (ADMS) allowing the creation of small or very large rings. Each DPT ring supports a maximum of 64 nodes.
•Leverages fiber optics capacity at OC-12c line rates.
The WAN card has two SC duplex ports. Each SC duplex port provides the physical connection to an adjacent device in a DPT ring.
•Supports single mode fiber transmissions.
•Allows data to obtain fair-shared access to the OC-12c rings.
•Supports Version 1 SRP Protocol
•Implements protection mechanisms, including wrap and unwrap, in the event of fiber or node failure.
The Cisco uBR10-SRP-OC12SML DPT WAN line card requires two card slots. For that reason, the card is normally installed in Slot 2 and Slot 4 if you are using two cards. If you are using only one card than install the card in Slot 2, Slot 3 or Slot 4. See Figure 1.
Attenuation
The Cisco uBR10-SRP-OC12SML DPT WAN line card is designed to be used at any distance between 15 and 40 kilometers (km). For shorter distance operations (less than 15 km), use a 10 dBm optical attenuator on the link (see Figure 6) between the two nodes to prevent clipping and over saturation of the optical receiver. The attenuator should be made of a non-metallic or plastic material.
The exact attenuation value is based on the real cable length or the number of couplers and splicers on the link. For example, 5 dBm attenuator could be used in a 7 km link.
Note The maximum distance of 40 km assumes that the 1310 nm SMF optical cable attenuation is no more than 0.5dB per kilometer; and that there is no optical coupler or splicer in on the link (each could add 0.5dB loss).
Cisco recommends the use of a SC/PC female to SC/PC male optical attenuator.
Tip The SC/PC (Standard Connector/Physical Contact) denotes a connector with a rectangular shape. The surfaces are parallel with respect to the port (not angled). SC/APC (Standard Connector Angled Physical Contact) denotes an angled surface.
Caution Make sure that you obtain the correct connector type (SC/PC) when purchasing optical attenuators. Angled SC/APC type mating surfaces can damage the Cisco uBR10-SRP-OC12SML DPT WAN line card (RX port) interface.
See "Connectors and Cables" section.

Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
•Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
•Disconnect all power and external cables before moving a chassis.
•Do not work alone when potentially hazardous conditions exist.
•Never assume that power has been disconnected from a circuit; always check.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent failures. The AC-input power shelf and its AC power modules contain a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use an antistatic strap each time you handle the modules.
Following are guidelines for preventing ESD damage:
•Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before removing a card from the chassis, connect the equipment end of the strap to a bare metal, unpainted surface on the chassis or rack-mount.
•Handle components by the carrier edges only; avoid touching the card components or any connector pins.
•When removing a module, place it on an antistatic surface or in a static-shielding bag. If the module will be returned to the factory, immediately place it in a static-shielding bag.
•Avoid contact between the modules and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

The maximum distance of 40 km assumes that:
1. The 1310 nm SMF optical cable attenuation is no more than 0.5 dB per kilometer.
2. No optical coupler or splicer is on the link (each coupler or splicer adds 0.5 dB loss).
The exact attenuation value is based on:
1. The real cable length.
(For example: a 5 dBm attenuator may be used for a 7 km link.)
2. The number of couplers or splicers on the link.

Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.
Inquiries to Cisco TAC are categorized according to the urgency of the issue:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.
Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.
Cisco TAC Web Site
The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:
http://www.cisco.com/tac
All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:
http://www.cisco.com/register/
If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:
http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In addition, please have available your service agreement number and your product serial number.
