inforamtion for the Cisco 10720 Internet Router document.
Site Wiring Distance and Interference Guidelines
This section offers site wiring guidelines for setting up the site plant wiring and cabling. When planning
the location of the new system, consider the following:
• Electromagnetic Interference, page ix
• Distance Limitations for Signaling and Unshielded Conductors, page x
Electromagnetic Interference
Electromagnetic interference can occur between the field and the signals on the wires when the wires are
run for any significant distance. This fact has two implications for the construction of plant wiring:
• Poor wiring practice can result in radio interference emanating from the plant wiring.
• Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy and/or cause
interference with the signal drivers and receivers in the Cisco 10720 Internet Router, and can create
an electrical hazard by conducting power surges through lines and into equipment.
78-13113-06 B0
NoteTo predict and remedy strong EMI, consult experts in radio frequency interference (RFI).
A good quality twisted pair cable or shielded twisted pair cable helps limit radiation and noise induced
into the cable minimizing:
• Potential for radio interference
• Potential for interference with the data transmission.

Translated Safety Warnings
Distance Limitations for Signaling and Unshielded Conductors
Give special consideration to the effect of a lightning strike in the site vicinity if wires exceed
recommended distances, or if wires pass between buildings. The electromagnetic pulse (EMP) caused
by lightning or other high-energy phenomena can easily couple enough energy into unshielded
conductors to destroy electronic devices.
Provide a properly grounded and shielded environment. Consider electrical surge suppression issues by
addressing the following items:
• Potential surge sources
• Distance
CautionSplicing can degrade cable performance.
Translated Safety Warnings
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may
harm you. A warning symbol precedes each warning statement. The following paragraph is an example
of a safety warning. It identifies the warning symbol and associates it with a bodily injury hazard. The
remaining paragraphs in this section are translations of the initial safety warning.

The Cisco 10720 Internet Router provides network access using Ethernet and optional Dynamic Packet
Transport (DPT), Packet over SONET (POS), or IEEE 802.17 RPR technology for optical connectivity.
Each router is equipped with one uplink card located in the upper card slot. The OC-48 RPR/SRP,
OC-48/STM-16c DPT, and POS/DPT uplink cards are equipped with dual OC-48c/STM-16c optical
uplink network ports with an aggregate bandwidth of 5 Gbps. The console/auxiliary card provides
console and serial (AUX) ports only.
Although the console/auxiliary card does not provide uplink capabilities, it is described here because it
is installed the same as the DPT and POS/DPT uplink cards. You can use the
Cisco 10720 Internet Router console/auxiliary card with either a 24-Port 10/100 Ethernet TX access
card or a Combined 4-Port Gigabit Ethernet 8-Port 10/100 Ethernet TX access card to customize the
Cisco 10720 Internet Router as an Ethernet-only router.
For DPT and POS/DPT uplink cards, the cable connector is LC fiber-optic connector. For the RPR/SRP
uplink card, the fiber-optic cable connects to an LC connector in a small form-factor pluggable (SFP)
optical connector. When connecting to DPT networks, the left port is the Spatial Reuse Protocol (SRP)
side A, and the right port is side B. (See Figure 1-1.) When connecting to POS networks, there are two
individual ports. Each port consists of transmit (TX) and receive (RX). (See Figure 1-2.) When
connecting to DPT networks in Resilient Pack Rings (IEEE 802.17 RPR) mode, the left port is span
West, and the right port is span East. When in the Spatial Reuse Protocol (SRP) mode, the left port is
side A, and the right port is side B. (See Figure 1-3.)
Chapter 1 Overview and Specifications
For information and instructions on connecting the optical cables to the DPT uplink card or to the
RPR/SRP uplink card and for setting up four-node rings, see Chapter 1, “Overview and Specifications”
and Chapter 4, “Creating a Four-Node Ring Using the Uplink Cards.”

Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage can occur when electronic cards or components are improperly
handled. This will cause complete or intermittent failures. We recommend using an ESD-preventive
strap when you handle a router or one of its components. Electromagnetic interference (EMI) shielding
is an integral component of the router.
2-4
Book Title
78-13113-06 B0
Chapter 2 Preparing for Installation
Following are guidelines for preventing ESD damage:
• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
Connect the equipment end of the connection cord to bare metal on the router chassis. (See
Figure 2-1.)
• Attach an ESD-preventive wrist strap to your wrist, and to the chassis or to a bare metal surface.
(See Figure 2-1.)
• The wrist strap protects equipment from ESD voltages on the body only; ESD voltages on clothing
can still cause damage to electronic components.
CautionTo avoid ESD damage to the equipment, periodically check the resistance value of the
ESD-preventive wrist strap. The resistance measurement should be between 1 and 10 megohms
(Mohms).

Removing the Cable-Management System
The cable-management system, located on the front of the Cisco 10720 Internet Router, organizes the
interface cables that lead into and away from the router. To keep the cables free of sharp bends, extend
the cables from the center out both sides of the cable-management tray. Excessive bending of an interface
cable can degrade performance and possibly harm the cable. The cable-management system consists of
the cable-management tray and the cable-management cover.

The maximum distance for single-mode installations is determined by the amount of light loss in the
fiber path. Good quality single-mode, short-reach fiber with very few splices can carry an uplink card
signal two kilometers.
If your environment requires the signal to travel close to the typical maximum distance (see Chapter 1,
“Overview and Specifications”), use an optical time domain reflectometer (OTDR) to measure the power
loss.

Installing the Cable-Management System
The cable-management system, located on the front of the router, organizes the interface cables. To keep
the cables free of sharp bends, extend the cables from the center out both sides of the cable-management
system. Excessive bending of an interface cable can degrade performance and possibly harm the cable.
Perform the following steps to install the cable-management system:
Step 1Power down your router. (See the “Powering Down the Router” section on page 3-2.)
Step 2Attach an ESD-preventive wrist strap to your wrist, and to the router or to a bare metal surface. (See the

After tightening the receptacle screw for the ground, +48V, and –48V DC-input leads, use cable ties to
secure the three leads. (See Figure 3-30.)
Book Title

Turning On Power to the Router
NoteLeave a small service loop in the ground lead to ensure that the ground lead is the last lead to
disconnect from the power supply if a great deal of strain is placed on the DC-input leads. It is
important that the ground power lead is the last to disconnect from the power supply terminal.
NoteAllow sufficient slack in the power cable leads for strain relief. The power cable leads should be
adequately secured to prevent the power supply terminal connections from being subjected to strain.
Step 7After wiring the DC power supply, remove the tape from the circuit breaker switch handle and turn on
power by moving the handle of the circuit breaker to the on position.
If you are installing the cable-management system, go to the “Installing the Cable-Management System”
section on page 3-15. If not, install the cables, and then power up the router.

Troubleshooting the POS Uplink Card Installation
This section provides information for troubleshooting the POS/DPT uplink card installation.
Alarm Processing
The following system alarms are monitored by the POS uplink card and reported to the console port:
• Loss-of-Signal (LOS)
• Loss-of-Frame (LOF)

Troubleshooting the POS Uplink Card Installation
• STS Path Loss-of-Pointer (LOP)
• STS Path Alarm Indication Signal (AIS)
• STS Path Remote Defect Indication (RDI)
• B1 Bit Error Rate (BER) threshold crossing alarm (b1-tca)
• B2 BER threshold crossing alarm (b2-tca)
• B3 BER threshold crossing alarm (b3-tca)
• Line Bit Interleave Parity (LBIP) BER in excess of signal degrade threshold (sd-ber)
• LBIP BER in excess of signal failure threshold (sf-ber)
At any time the status of the SONET/SDH alarm and signal events can be examined using the show
controllers command, as shown in the following example:
BER thresholds: SF = 10e-4 SD = 10e-6
TCA thresholds: B1 = 10e-6 B2 = 10e-6 B3 = 10e-6

Loopback Testing
The POS uplink card supports two loopback modes for network testing, fault isolation, and agency
compliance. The uplink card loopback modes are:
Internal loopback mode—Packets sent from the Cisco 10720 Internet Router out of the uplink card POS
port TX optics are also looped back into the Cisco 10720 Internet Router.
Line loopback mode—Packets received by the POS uplink card port RX optics and sent into the
Cisco 10720 Internet Router are also looped back out of the uplink card port TX optics.
Loopback testing is enabled through software. See the Cisco IOS Software Configuration for the
Cisco 10720 Internet Router.
Additional Troubleshooting Resources
For more troubleshooting information for the uplink card, refer to the following publications:
• Chapter 4, “Troubleshooting”, in the Cisco 10720 Internet Router Installation and Configuration
Guide
