4.3.2 Electrical Equipment Guidelines

Follow these guidelines when you handle any electrical equipment:

• Before beginning any procedure 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 if potentially hazardous conditions exist, and never assume that power is 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.

4.3.3 Guidelines for Wiring Outside the Central Office

Use the following guidelines when you handle any equipment that is connected to telephone wiring 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 you install or modify telephone lines.

4.3.4 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. Port adapters 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. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing 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 you install 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 you remove 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 removed component board-side-up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap protects components from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. Ensure the measurement is between 1 and 10 megohms.

5.1 ATUC-1-4DMT-2 Faceplate

Figure 1 shows the faceplate of an ATUC-1-4DMT-2 line card.

5.2 ATUC-1-4DMT-2 LED Indicators

Table 1 describes the LEDs on the ATUC-1-4DMT-2 line card.

Caution Do not remove the ATUC-1-4DMT-2 line card from the chassis if the card's Active LED is blinking. If a line card is removed while it is loading microcode, the card's flash memory might be damaged, making it necessary to replace the card.

5.3 Modem Mapping to Cisco 6260 Champ Connectors

Each of the four modems on an ATUC-1-4DMT-2 line card is connected to one of ten 50-pin Champ connectors located at the top of the Cisco 6260 chassis. Each modem is mapped to a pair of pins on the Champ connector; pin selection depends on the slot where the line card is installed. Table 2 through Table 11 list the pin mapping for the modem-to-Champ connections.

6. How the ATUC-1-4DMT-2 Line Card Handles Traffic

During the training sequence, the ATUC-1-4DMT-2 card automatically detects the type of CPE to which it is connected. After detecting the CPE type, the card configures itself for one of the following modes of operation:

• G.dmt - ITU G.992.1 Annex A for ADSL over POTS

• G.lite - ITU G.992.2 Annex A for ADSL over POTS

• ANSI Issue 2

The ATUC-1-4DMT-2 supports the following:

• Upstream line rates: 32 to 864 kbps in increments of 32 kbps

• Downstream line rates: 32 to 8032 kbps in increments of 32 kbps

• Symmetrical line rate: matches upstream and downstream rates

• The ability to obtain and report the actual acquired modem rate if the desired rate cannot be achieved

6.1 Downstream Data Flow

Downstream refers to cells moving from the NI-2 card to the subscriber. Cells moving downstream are processed as follows:

1. The backplane serial to Utopia interface field-programmable gate array (FPGA) receives unscrambled, serialized, ATM cells from the data serial bus (DSB).

2. The system performs a cell delineation with header error control (HEC) check within the backplane serial to Utopia interface FPGA.

3. The system directs cells to the Interleave path queue in the backplane serial to Utopia interface FPGA cell queue.

4. The system passes cells across the Utopia 2 interface to the ADI AD20msp918 chipset. The backplane serial to Utopia interface FPGA acts as master with the ADI AD20msp918 acting as the slave.

5. The ADI AD20msp918 encapsulates and transmits the data to the subscriber line as defined by ANSI T1.413 Issue 2 or 6.992.

6.2 Upstream Data Flow

Upstream refers to cells moving from DSL subscribers toward the NI-2 card. Cells moving upstream are processed as follows:

1. The subscriber line terminates with the ADI AD20msp918 chipset as defined by ANSI T1.413 Issue 2 or 6.992.x.

2. The ADI AD20msp918 passes unscrambled cells identified by polling across the Utopia interface to the backplane serial to Utopia interface FPGA.

3. The backplane serial to Utopia interface serializes the ATM cells to the NI-2 card.

6.3 Microprocessor Functions

The microprocessor begins to execute out of the boot flash after reset. This code contains a boot loader for the serial management bus (SMB). The NI-2 sends the ATUC-1-4DMT-2 card its run-time image over the SMB, and the main code is loaded into SRAM.

After the main image is running, the microprocessor can load the serial data bus (SDB)/UTOPIA FPGA and initialize all of the modems.

6.4 ATM Virtual Circuit Support

The ATUC-1-4DMT-2 card supports up to 256 virtual channel identifiers (VCIs) and virtual path identifiers (VPIs) per port and enables you to use a default VPI/VCI mapping or to provision the VPI/VCI mapping using IOS configuration commands.

7. Installing and Removing ATUC-1-4DMT-2 Cards

Follow the procedures in this section to install an ATUC-1-4DMT-2. You need not disconnect power before inserting an ATUC-1-4DMT-2 into the Cisco 6260 chassis.

7.1 Installing an ATUC-1-4DMT-2 Card

You must install ATUC-1-4DMT-2 cards in slots 1 to 9 or 12 to 32 in the Cisco 6260 chassis. To install an ATUC-1-4DMT-2 card into a Cisco 6260 chassis, complete the following steps:

Step 1 Hold the ATUC-1-4DMT-2 card vertically, with the card's faceplate toward you and the connectors facing the chassis slot.

Step 2 Align the upper and lower edges of the ATUC-1-4DMT-2 with the upper and lower guides in the chassis shelf.

Step 3 Slide the card into the slot, applying gentle pressure with both hands at the top and bottom of the faceplate until the card contacts the backplane.

Step 4 Ensure that the extraction lever on the card engages the upper front rail of the chassis.

Step 5 Press the extraction lever down. This action connects the card to the backplane.

Step 6 Secure the ATUC-1-4DMT-2 to the chassis by tightening the upper and lower retaining screws.

When you insert the card, code on the card runs an internal test to ensure that the card is operating properly. If the card completes the internal test successfully, the READY LED lights.

Step 7 Using a flat-blade screwdriver, turn the locking tab so that it overlaps the ATUC-1-4DMT-2 card to prevent inadvertent dislodging. Figure 3 shows how to position the locking tab.

Step 8 Install blank faceplates to cover unused slots in the chassis. Secure each faceplate to the chassis by tightening the upper and lower retaining screws.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

7.2 Removing an ATUC-1-4DMT-2 Card

To remove an ATUC-1-4DMT-2 card from a Cisco 6260 chassis, complete the following steps:

Step 1 Using a flat-blade screwdriver, turn the locking tab so that it does not overlap the ATUC-1-4DMT-2 card.

Step 2 Unscrew the retaining screws that secure the ATUC-1-4DMT-2 card to the chassis.

Step 3 Lift the extraction lever. This action disconnects the card from the backplane.

Step 4 Slide the ATUC-1-4MT card out from the slot.

8. Software Configuration and Provisioning

You can configure a Cisco 6260 slot for an ATUC-1-4DMT-2 card either before or after you insert the card.

To configure a slot, use the global configuration command slot slot# atuc-1-4dmt. For example,

c6260# conf t
c6260(config)# slot 20 atuc-1-4dmt
 

After you execute the slot command, the system creates default configuration information for the interfaces on the new card. These interface configurations are automatically added to the system's running-config file. You can enter show running-config to view the file. Use the copy command in privileged EXEC mode to save the configuration changes to the startup-config file, as shown below.

c6260(config)# copy running-config startup-config
