Cisco ATUC-4DMT-ISDN Installation And Configuration Manual

Introduction

Cisco ATUC-4DMT-ISDN Line Card
Installation and Configuration

Product Number: ATUC-1-4DMT-I(=)

This publication contains instructions that describe how to install and configure
Cisco ATUC-4DMT-ISDN line cards. This high-density line card supports discrete multitone (DMT)
over Integrated Services Digital Network (ISDN) protocols that employ 2B1Q- or 4B3T-based
encoding.

You canonly use this line card in Cisco 6260 digital subscriber line access multiplexers (DSLAMs)that
contain the NI-2 network interface processor module running Cisco IOS software. You can deploy the
line cards described in this document in either of two ways:

• A direct connect configuration—Telco equipment routes DMT signals only between customer

modems and the line cards (see the “Line Card Direct Connect Deployment” section on page 11).

• A splitter configuration—Telco equipment includes DMT/ISDN splitters to separate or combine

ISDN and DMT signals at the central office (CO) and at the customer site (see the “Line Card
Splitter Deployment” section on page 13).

Line Card Description

You can only use ATUC-4DMT-ISDN line cards in ISDN service in Cisco 6260 DLSAM chassis.

• In a direct connect configuration—DMT signals are routed directly between the line cards and the

customer modems.

• In a splitter connected DMT/ISDN configuration—Telco equipment separates DMT signals from

or combines them with ISDN signals if the customer premises equipment (CPE) includes ISDN
telephone service.

The ATUC-4DMT-ISDN line card

• Handles DMT signals only in both direct connect and splitterless deployments

• Requires that its DMT modem ports be connected directly to a CO facility main distribution frame

(MDF) when used in splitterless CPE installations

• Requires that its DMT modem ports be connected to an ADC Telecommunications, Inc. central

office high-density 240-port chassis (DMT/ISDN) signal splitter or other Cisco qualified
DMT/ISDN signal splitter when used in CPE ISDN installations

• Contains four modems: two on the motherboard and two on an attached daughter board

• Only operates with an NI-2 network interface processor module running Cisco IOS software in a

Cisco 6260 DSLAM chassis

In CPE installations with ISDN service on the same wire pair,you mustuse aDMT/ISDN signalsplitter
to separate and isolate ISDN and DMT signal frequencybands. The linecard contains filters that reject
the ISDN spectrum (or signal) during operation.

Guidelines for Wiring Outside the Central Office

Use the following guidelines when working with equipment thatis connected to telephonewiring or to
other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for wet

locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic line cards or components are
improperly handled, results in complete or intermittent failures. Port adapters and processor line cards
consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI)
shielding and connectors are integral components of the carrier. Although the metal carrier helps to
protect the board from ESD, use a preventive antistatic strap during handling.

Observe the following guidelines to prevent equipment ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• When installing a component, use any available ejector levers or captive installation screws to

properly seat the bus connectors in the backplane or midplane. These devices prevent accidental
removal, provide proper grounding for the system, and help to ensure that bus connectors are
properly seated.

• When removing a component, use any available ejector levers or captive installation screws to

release the bus connectors from the backplane or midplane.

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or

connectors.

• Place a removedcomponent board-side-up onan antistaticsurface or ina static-shieldingcontainer.

If you plan to return the component to the factory, immediately place it in a static-shielding
container.

• Avoid contactbetween the printed circuit boards and clothing.The wriststrap protects components

from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

Caution Never attempt to remove the printed circuit board from the metal carrier. For safety,

periodically check the resistance valueof the antistatic strap. The measurement should be
between 1 and 10 megohms.

Installation Prerequisites

This section describes software requirements and lists the parts and tools that you need to install an
ATUC-4DMT-ISDN line card in a Cisco 6260 DLSAM chassis.

Software Requirements

Table 1 lists the Cisco IOS release you should use to configure and manage line cards in
Cisco 6260 DSLAMs.

Table 1 Line Card Software Requirements

Installation Prerequisites

Hardware Platform Recommended Minimum Cisco IOS Release

Cisco 6260 NI-2 DSLAM Cisco IOS Release 12.1(3)DA or later

Parts and Tools

You do not need special parts or tools to install a line card. However, you should use ESD-preventive
equipment or the disposable grounding wrist strap included with the line card you receive. You also
need a small standard screwdriver to rotate the line card locking tabs.

Installing and Removing Line Cards

To install any line card in a Cisco 6260 DSLAM chassis, follow the procedures in the “Line Card
Installation” section on page 5. To remove a line card, follow the procedures in the “Line Card
Removal” section on page 8.

Note You do not need to disconnect power before you insert or remove a line card from a

Cisco 6260 NI-2 DSLAM chassis.

Line Card Installation

78-10981-01

You can install up to 30 ATUC-4DMT-ISDN line cards in the following Cisco 6260 DSLAM slots

• Slots 1 to 9—Upper shelf

• Slots 12 to 17—Upper shelf

• Slots 18 to 32—Lower shelf

• Slot 10—Reserved for a full-length NI-2 network interface module

Installing and Removing Line Cards

• Slot 11 and any other empty Cisco 6260 NI-2 DSLAM slot—Must contain a blank faceplate (refer

to the Cisco 6260 Hardware Installation and Troubleshooting Guide for details)

To install a line card in a Cisco 6260 chassis slot, perform the following steps:

Caution Static voltages as low as 30 volts can cause latent damage to circuitry. Be sure to observe all

standard antistatic procedures (for example, wear a grounding strap).

Note If an unexpected result occurs when you perform the following procedure refer to the

Cisco 6260 Hardware Installation and Troubleshooting Guide.

Step Procedure

Step 1

Hold theline card vertically, with its faceplatetoward youand its connector fingers facingthe
DSLAM line card slot.

Step 2

Align the upper and lower edges of the line card with the upper and lower guides in the
DSLAM line card slot.

Step 3

Slide the linecard intoits DSLAMslot (Figure 1) byapplying gentle pressurewith bothhands
at the top and bottom of its faceplate until its finger contacts enter the backplane connector.

Step 4

Rotate the faceplate locking tab on theline cardto itsunlocked position(see Figure 2)and
engage the locking lever at the upper front rail of the DSLAM chassis (see Figure 1).

Step 5

Press the lockinglever down; thisaction inserts theline cardfinger contacts intothe backplane
connector.

Step 6

Rotate the line card locking tab with a small screwdriver. When you insert the line card, the
green StatusLED on thefaceplate should light(firmware on the line card runs an internal test
to ensure proper line card operation). If the Status LED does not light, replace the line card.

Step 7

Install a blank faceplate to cover each empty slot in the Cisco 6260 DSLAM. Secure the
faceplate to the DSLAM chassis by rotating its locking tab to the locked position (see
Figure 2).

Warning

6

Blank faceplates and cover panels serve three important functions: 1) they prevent
exposure to hazardous voltages and currents inside the chassis; 2) they constrain
electromagnetic interference (EMI) that may otherwise disrupt other equipment;
and 3) theydirect theflowof coolingair throughthe chassis.Do notoperate thesystem
unless all line cards, blank faceplates, front covers, and rear covers are in place.
