Cisco AS5800 Universal Access Server Overview

The Cisco AS5800 Universal Access Server is a high-density, ISDN and modem WAN aggregation system that provides both digital and analog call termination. It is intended to be used in service provider dial point-of-presence (POP), or centralized enterprise dial environments. The access server chassis components include a Cisco 5814 dial shelf and a Cisco 7206 router shelf. An optional AC power shelf is also available.

The dial shelf and router shelf are bundled, and can be ordered to support either AC or DC power. Included in the dial shelf is a blower assembly, filter module, and power entry modules (PEMs). Also included in the bundled system are ingress trunk cards, modem cards, dial shelf controller cards, Flash memory PCMCIA cards, cables, and Cisco IOS software. The dial shelf feature cards and host router shelf communicate via a dial shelf interconnect cable.

The dial shelf contains 14 slots (numbered 0 through 13 on the backplane) and can support up to 10 modem cards, 2 CT1 or CE1 trunk cards, and 2 dial shelf controller cards (in the near future). Only slots 0 through 5 are designed to recognize trunk cards and are prioritized for clock selection beginning with slot 0; therefore, you must install trunk cards in the first six slots.

The router shelf supports the dial shelf and performs all routing and packet processing. The router shelf also houses the main system software images.

CT1 and CE1 Trunk Card Overview

Channelized ingress interfaces reside on either CT1 or CE1 trunk cards that are installed in the Cisco 5814 dial shelf. A CT1 or CE1 trunk card contains all necessary functionality to terminate incoming telephone calls. The channelized trunk card is configured in the factory for either T1 or E1 framing, depending on your order.

shows the CT1 and CE1 trunk card components.

Figure 3 CT1 and CE1 Trunk Card

The CT1 and CE1 trunk cards perform the following functions:

Terminate up to 12 T1 or 12 E1 lines

The CE1 trunk card provides physical termination for up to 12 E1 lines and connects to an external network termination (NT1) device, while the CT1 trunk card provides physical termination for up to 12 T1/Primary Rate Interface (PRI) lines, includes channel service units (CSUs), and connects directly to the telco network.

Demultiplex DS0s

A framer removes framing and embedded signaling bits (or inserts them depending on the direction of the flow), and the framer CPU sends the data stream to onboard time division multiplexing (TDM) resources, which break out each call (DS0) and pass each call to an appropriate call termination resource. Digital or ISDN-originated calls are terminated onboard the CT1 or CE1 trunk card on High-level Data Link Control (HDLC) controllers, and analog modem-originated calls are passed over the dial shelf backplane TDM bus to an available modem resource. The system software controls modem and HDLC resource management.

Respond to time-sensitive signaling

Each individual T1 or E1 port can be used as the system clocking reference. Each CT1 or CE1 trunk card can supply two clocks from any two of its twelve ports. You can assign priorities to these clocks, or accept the default values assigned by the software.

Default values for clocking are based on the following parameters:

(a) Ports are prioritized from 0-11. The port with the lowest number has the highest priority.

(b) Slots are prioritized from slot 0 to slot 5. The lowest slot number has the highest priority.

(c) Clocks are prioritized by slot number. The highest priority clock is selected from the card in slot 0. If this clock fails, the highest priority clock from the card in slot 1 becomes the default clock, and so forth.

The trunk card then forwards the clocks to the dial shelf controller. The dial shelf controller selects the highest priority clock as the system primary clock, and the rest of the clocks remain in a prioritized backup queue.

Instead of using the default algorithm for clock selection, you can specify clocks through configuration. You configure the clocks globally, and can select a maximum of two clocks per trunk card. For example, if you install three trunk cards, you can configure up to six clocks. (While two trunk cards are sufficient to give full coverage to ten modem cards, you can have up to six trunk cards seated in slots 0 through 5 for a maximum selection of twelve clocks.)

If you configure fewer than two clocks on a trunk card and all other configured clocks fail, the clock selection will resort to the default algorithm on that card and the second clock will be selected automatically.

Process counting information for performance monitoring

Support online insertion and removal (OIR)

The trunk card supports OIR, a feature that allows you to remove and replace trunk cards in the Cisco 5814 dial shelf while the system is operating without disrupting other cards and their associated calls. If you remove a trunk card while the system is operating, all calls associated with the 12 E1 or T1 lines on that card are dropped. Calls being handled by other trunk or modem cards, however, are not affected.

Trunk Card Bantam Jacks

Passive port monitoring is supported through two shared bantam jacks located at the bottom of the trunk card front panel (see ). The bantam jacks allow you to connect a network monitoring device to the trunk card to detect T1 or E1 errors.

The 4-character LCD indicates which of the 12 T1 or E1 lines are to be monitored or inspected using the bantam jacks.

To enable the bantam jacks for port monitoring, follow these steps:


Step 1 Push and quickly release the pushbutton (labeled monitor #) below the LCD to toggle to the port number you want to display.

You must release the button within two seconds to advance through the port numbers (from 0 to 11). After port 11, the display returns to port 0. As you advance through the port numbers, the port-associated LEDs reflect the configuration status and alarm conditions of the port number displayed in the LCD.

Step 2 Push and hold the monitor button for two or more seconds to enable the bantam jack. To disable the bantam jack and return to toggle mode, press the button again and hold it for two or more seconds.

When you release the button, the port no longer toggles through the port numbers, the letter "B" is displayed in the LCD, and the bantam jacks are enabled.

Step 3 Repeat Step 1 and Step 2 to enable the bantam jacks for each port you wish to monitor.

Warning   

The ports labeled "Network Clock," "10BaseT," "Dial Shelf Interconnect," "Console," and "Alarms" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the E1/T1 circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.


Online Insertion and Removal

The Cisco AS5800 Universal Access Server supports online insertion and removal (OIR). This feature allows you to remove and replace a dial shelf controller card or feature card (trunk card or modem card) while the system is operating without affecting system operation.


Note   This section describes the mechanical functions of the system components and emphasizes the importance of following the correct procedures to avoid unnecessary circuit card failures. This section is for background information only. Refer to the section "Removing and Replacing a Trunk Card" for specific procedures regarding the CT1 and CE1 trunk card.


Each dial shelf controller card and feature card contains a female connector with which it connects to a male connector on the system backplane. Each male backplane connector comprises a set of tiered pins, in two lengths. The backplane pins send specific signals to the system as they make contact with the card connectors. The system assesses the signals it receives and the order in which it receives them to determine what event is occurring and what task it needs to perform, such as reinitializing new interfaces or shutting down removed ones.

Each dial shelf controller card and feature card is designed with two ejector levers to be used when you install or remove a card (see ). The function of the ejector levers is to align and securely seat the card connectors in the backplane.


Caution   
Do not force the dial shelf controller cards or feature cards into a slot, as this can damage the backplane connector pins if they are not aligned properly with the card connectors.


Note   To avoid erroneous failure messages, you must allow at least 15 seconds for the system to reinitialize and note current interface configurations before you remove or insert a dial shelf controller card or feature card in the dial shelf.


Safety Guidelines

This section provides safety and ESD-prevention guidelines to help you avoid injury to yourself and avoid damage to the equipment. The following safety guidelines are recommended when working with any equipment that connects to electrical power or telephone wiring:

Locate the emergency power-off switch for the room in which you are working before beginning any procedures requiring access to the chassis interior.

Never work alone when potentially hazardous conditions exist.

Never assume that power has been disconnected from a circuit; always check.

Never 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.

This unit is to be installed in a restricted access area in accordance with articles 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA 70.

Telephone Wiring Guidelines

The following guidelines are recommended when working with 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.

Always use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when printed circuit cards are improperly handled and results in complete or intermittent failures.

The system feature cards and dial shelf controller cards consist of a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and ejector levers are integral components of the carrier. Handle the cards by their carrier edges or ejector levers only; never touch the printed circuitry, card components, or connector pins.

Although the metal carrier helps to protect the printed circuitry from ESD, you should wear a preventive antistatic strap whenever handling feature cards or dial shelf controller cards. Ensure that the strap makes good skin contact, and connect the strap's clip to an unpainted chassis surface to safely channel unwanted ESD voltages to ground.

The following are guidelines for preventing ESD damage:

Always use an ESD wrist strap or ankle strap when installing or replacing system components. Ensure that the ESD strap makes contact with your skin.

Handle the trunk cards by their metal carrier edges and handles only; avoid touching the printed circuit card components or any connector pins.

Place all system components that have been removed on an antistatic surface with the printed circuit card components facing upward, or in a static shielding bag. If you are returning a feature card to the factory, immediately place it in a static shielding bag.


Caution   
Periodically check the resistance value of the antistatic strap. The measurement should be within the range of 1 and 10 megohms.

Removing and Replacing a Trunk Card

Depending on your configuration requirements, you might need to replace existing trunk cards or install new trunk cards in your Cisco 5814 dial shelf. Because the system is designed to recognize trunk cards only when they are installed in the first six slots, you must install trunk cards in slots numbered slots 0 through 5 on the dial shelf backplane.


Note   The OIR feature allows you to install and remove a trunk card without powering off system power. Refer to the section "Online Insertion and Removal" for a description of OIR.


To remove a trunk card without dropping the calls or connections, you must first take the trunk card out of service by using the busyout command to busyout DS0s and modem resources as calls are completed. The busyout command is executed on a per card (slot) basis.

The busyout command has the format busyout shelf-number/slot-number, where shelf number is a user-designated value from 0-9999, and slot number is 0-5. The following example shows how to busy-out the card in slot 0 on shelf 5:

router# busyout 5/0
router#

If you are replacing a failed trunk card, we recommend you proceed as follows:

1 Busyout the card

2 Remove the existing card

3 Install the new trunk card in the same slot

When replacing a trunk card with a new trunk card of the same type in the same slot, the system software will recognize the new trunk card interfaces and bring them up automatically. No additional configuration is needed. A trunk card installed in any other slot will affect the clocking source.


Caution   
To avoid erroneous failure messages, remove or insert only one trunk card at a time. Also, after inserting or removing a trunk card, allow at least 15 seconds before removing or inserting another trunk card so that the system can reinitialize and note the current configuration of all interfaces.


Note   The system brings online only interfaces that match the current configuration and were previously configured as up; all other interfaces require that you configure them with the configure command. For information on the configure command, refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide that shipped with your system.


Tools and Parts Required

You need the following tools and parts to install or replace a trunk card. If you need additional equipment, contact a service representative for ordering information.

CT1 or CE1 trunk card (DS58-12CT1=, DS58-12CE1=, respectively)

CT1 or CE1 interface cables (See the sections "CT1 Trunk Card Cables and Pinouts" and "CE1 Trunk Card Cables and Pinouts" for a list of product numbers.)

Cable ties

Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field replaceable units (FRUs), and spares.

Cisco AS5800 Universal Access Server Software Installation and Configuration Guide (DOC-AS5800-SICG)

Removing a Trunk Card

To remove a trunk card from the Cisco 5814 dial shelf, complete the following steps:


Warning   

Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.



Caution   
Trunk cards weigh 8 lb (3.6 kg) each. Use two hands when removing or replacing a trunk card.

To remove a trunk card from the Cisco 5814 dial shelf, follow these steps:


Step 1 Note the slot in which the trunk card is installed. If you decide to install the new trunk card in the same slot, this will hasten the installation process.

Step 2 Initialize the software busyout procedure by entering the following command in privileged EXEC mode:

busyout shelf-number/slot-number

Step 3 Verify the yellow maintenance LED lights on the trunk card, which indicates the card is offline and ready to be removed.

Step 4 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.


Caution   
To prevent ESD damage, handle trunk cards by ejector levers and carrier edges only, and use an ESD-preventive wrist strap or other grounding device.

Step 5 Disconnect all CT1 or CE1 trunk line cables and secure them out of the way using cable ties, if necessary.

Step 6 Using a Number 2 Phillips screwdriver, loosen the panel fasteners at the top and bottom of the trunk card front panel. (See .)

Figure 13 Using the Ejector Lever

Step 7 Pull either the top or bottom ejector lever away from the trunk card front panel to disengage the trunk card from the backplane connector, as shown in .


Caution   
Always use the ejector levers to disengage or seat trunk cards, modem cards, or dial shelf controller cards in the backplane. Failure to do so can cause erroneous system error messages indicating a card failure. However, do not use the ejector levers to lift or support the weight of the cards.

Step 8 Grasp the ejector levers and pull the trunk card partially out of the dial shelf slot until you can grasp the trunk card front panel with one hand. Place your other hand under the trunk card to balance the weight of the card as you pull it out of the slot. (See .)

Step 9 Pull the trunk card straight out of the slot. Avoid touching the circuitry or any connector pins.

Figure 14 Removing and Replacing the CT1 or CE1 Trunk Card

Step 10 Place the removed trunk card on an antistatic mat or foam pad until you are ready to reinstall it in the chassis. If you plan to return the card to the factory, place it in an antistatic bag.

This completes the trunk card removal procedure. To install or replace a trunk card, proceed to the section "Replacing a Trunk Card."

Replacing a Trunk Card

To install the trunk card in the Cisco 5814 dial shelf, follow these steps:


Caution   
Trunk cards weigh 8 lb (3.6 kg) each. Use two hands when removing or replacing a trunk card.


Step 1 Ensure your ESD-preventive wrist strap is attached between you and an unpainted chassis surface.


Caution   
To prevent ESD damage, handle trunk cards by ejector levers and carrier edges only, and use an ESD-preventive wrist strap or other grounding device.

Step 2 Carefully align the trunk card carrier guides with the top and bottom grooves in the dial shelf slot. Avoid touching the circuitry or any connector pins.

Step 3 Slide the trunk card into the slot until the ejector levers make contact with the chassis frame. (See .)

Step 4 Seat the trunk card in the backplane by pushing the card firmly until the ejector levers fold in toward the trunk card front panel, and the front panel is flush with the chassis frame.


Caution   
Always use the ejector levers to disengage or seat trunk cards, modem cards, or dial shelf controller cards in the backplane. Failure to do so can cause erroneous system error messages indicating a card failure. However, do not use the ejector levers to lift or support the weight of the cards.

Step 5 Tighten the panel fasteners using a Number 2 Phillips screwdriver. This secures the backplane connection and ensures proper EMI shielding.


Caution   
Always tighten the panel fasteners on trunk cards. These fasteners prevent accidental removal and provide proper grounding for the system.

Step 6 Repeat Step 2 through Step 5 for any other trunk cards you want to install.


Caution   
To avoid erroneous failure messages, remove or insert only one trunk card at a time. Also, after inserting or removing a trunk card, allow at least 15 seconds before removing or inserting another trunk card so that the system can reinitialize and note the current configuration of all interfaces.

Step 7 Install a blank filler card (DS58-BLANK=) in all empty card slots to keep the chassis dust free and to maintain proper airflow.


Caution   
To prevent the overheating of internal components, always install blank filler cards in empty slots to maintain the proper flow of cooling air across the cards.

This completes the trunk card replacement procedure. Proceed to the section "Connecting Trunk Card Cables" to attach the interface cables.

Connecting Trunk Card Cables

The CT1 and CE1 trunk cards provide 12 RJ-45 receptacles for T1 or E1 lines. To connect T1or E1 lines, follow these steps:


Warning   

The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open.



Step 1 Attach the RJ-45 end of the T1 or E1 cables directly to the RJ-45 receptacles on the trunk card. (See .)

Step 2 For T1 cabling, attach the network end of your CT1 cables to your external network.

Step 3 For E1 cabling, attach the network end of your CE1 cables to your network termination (NT1) device.


Warning   

Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first.


Figure 15 CT1 and CE1 Trunk Card RJ-45 Cable Connections


Warning   

The ports labeled "Network Clock," "10BaseT," "Dial Shelf Interconnect," "Console," and "Alarms" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the E1/T1 circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.


Configuring Cable Length

When you configure your CT1 trunk cards, you must include the distance of the cable connected to the feature card. To specify this distance, you must use the cablelength command. No cablelength command is required for CE1 trunk cards.

If you change the cable length when installing and cabling a new trunk card, you need to specify cable length in your software configuration. The cablelength command is designed to recognize two basic fixed settings:

Cable Length Short

Cable Length Long

Cable Length Short

The following cable length short configurations define the length range (in feet), between your Network Access Server (NAS) and your repeater. The cablelength short command includes the following settings:

133 feet (0-133 feet)

266 feet (134-266 feet)

399 feet (267-399 feet)

533 feet (400-533 feet)

655 feet (534-655 feet)


Note   Although you can specify a cable length from 0 to 655 feet, the hardware only recognizes fixed configuration lengths. For example, if your cable length is 50 feet between your NAS and your repeater, you should configure your cable length using the 133-feet setting. If you later change the cable length to 200 feet, you should reconfigure your cable length using the 266-feet setting.


Cable Length Long

The following cable length long configurations define the length range in gain and pulse, between your Network Access Server (NAS) and your repeater. The cablelength long command includes the following gain and pulse arguments:

gain 26 (26db Gain)

gain 36 (36db Gain)

-15db (-15db pulse)

-22.5db (-22.5 db pulse)

-7.5db (-7.5 db pulse)

0db (0 db pulse)

To configure cable length, you must be in global configuration mode. lists commands to help you configure your CT1 lines using the cablelength command.


Note   When you configure your system for CT1 lines, you must also include additional commands to define framing, line code, clock source, signaling, etc. For complete instructions on how to configure your trunk card lines, refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide that shipped with your system.

Configuring Channelized T1 Cable Length

This completes the trunk card installation procedure. Proceed to the section "Verifying and Troubleshooting the Installation" to verify the installation.

Verifying and Troubleshooting the Installation

When you first power ON the access server, all LEDs light while the system runs a series of self-test diagnostics. After the system passes initial diagnostics, all LEDs go off. Later the LEDs light again as described in earlier in this document.

To complete the installation, verify the trunk card LEDs operate properly by observing the following LED states:

The power LED is ON.

If the power LED remains OFF, verify that the card is seated properly.

If the power LED lights on other trunk cards in the dial shelf, try inserting the trunk card in a different slot. If none of the power LEDs lights, check your dial shelf power connections, power entry modules, and AC-input power supplies (if present).

The HCPU LED is ON.

If the HCPU LED is OFF but the power LED is ON, the software image might have failed to load onto the card. The dial shelf controller will attempt to reload the software automatically. After a programmed number of attempts to reload the software image have failed, the dial shelf controller will power OFF the trunk card, and all LEDs will shut off.

If this happens, assume that the failure is due to defective hardware. Return the card to the factory for replacement.

The FCPU LED is ON.

If the FCPU LED is OFF while the HCPU LED is ON, either the hardware is defective or the framer processor software has crashed. To determine if the failure is software related, wait while the dial shelf controller card automatically reloads the card. The auto-reload feature on the dial shelf controller card will attempt to reload the software image. If the software fails to reload after the programmed number of times, assume that the failure is due to defective hardware. Return the card to the factory for replacement.

For further installation troubleshooting information, refer to the Cisco AS5800 Universal Access Server Hardware Installation and Configuration Guide. If you have any questions, or need assistance, proceed to the section "Cisco Connection Online."

Configuring the CT1 and CE1 Trunk Card

The Cisco 5814 dial shelf only recognizes CT1 and CE1 trunk cards in slots 0 through 5 within the dial shelf chassis; therefore, you must install trunk cards only in the first six slots.

If you are replacing a trunk card in the same slot as the one you just removed, the system automatically recognizes the previous system configuration, and no other configuration is needed.

If you are replacing a trunk card in a different slot from the one you just removed, additional configuration is needed. Refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide to configure the CT1 and CE1 interfaces.
