The Cisco AS5800 Universal Access Server supports channelized T1 (CT1) and channelized E1 (CE1) ingress interfaces that provide a synchronous telecommunication interface in both North American and international environments. The CT1 or CE1 trunk card is installed in the Cisco 5814 dial shelf in the Cisco AS5800 Universal Access Server.
This document explains how to remove and replace a CT1 or CE1 trunk card in the Cisco 5814 dial shelf chassis. It also includes steps for verifying and troubleshooting your trunk card installation.
The following sections are included in this document:
For information regarding the Cisco AS5800 Universal Access Server that is beyond the scope of this document or for additional information, use the following resources:
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.
Figure 1 shows a front view of a fully configured Cisco AS5800 Universal Access Server, and Figure 2 shows a rear view.
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.
Figure 3 shows the CT1 and CE1 trunk card components.
The CT1 and CE1 trunk cards perform the following functions:
Figure 4 shows two trunk cards installed in a fully configured Cisco 5814 dial shelf chassis.
The CT1 and CE1 trunk card front panel is designed with LED indicators and a liquid crystal display (LCD) to provide trunk card status and port-level monitoring information. Figure 5 shows the trunk card LEDs.
There are two types of LEDs for the T1 and E1 trunk cards:
All LEDs are visible from the front panel. (See Figure 5.) Table 1 lists the CT1 and CE1 trunk card LEDs and their functions.
| Indicator | Color | Description |
|---|---|---|
| PWR (Power OK) | Green | Lights when 5V power is active. |
| Maint (Maintenance) | Yellow | Lights when there are no active calls on the card and you have completed a card-level software busyout. Indicates the card is ready to be removed. |
| E1FR (E1 Framing) | Green | E1 trunk card only. Lights when the card is configured for E1 framing. |
| T1FR (T1 Framing) | Green | T1 trunk card only. Lights when the card is configured for T1 framing. |
| HCPU (Host CPU OK) | Green | Lights when the host CPU is operating normally. |
| FCPU (Framer CPU OK) | Green | Lights when the framer CPU is operating normally. |
The CT1 and CE1 trunk card front panels are designed with a liquid crystal display (LCD) to provide trunk card status and port-level monitoring information (see Figure 5 and Figure 6). The current port number displayed in the LCD also corresponds to the four port-associated LEDs. Table 2 describes the port-associated LEDs and their functions.
| Indicator | Color | Description |
|---|---|---|
| LALM (Local Alarm) | Yellow | Lights when an alarm condition is detected on incoming data. |
| RALM (Remote Alarm) | Yellow | Lights when the associated E1 port has detected loss of signal (LOS) or out of frame (OOF) errors. This occurs when the remote LIU1 receives errors and sends a signal to indicate presence of remote errors. |
| 75 (Ohm) | Green | E1 trunk card only. ON indicates 75 ohms, and OFF indicates 120 ohms. |
| NLOOP (Network Loopback) | Yellow | Lights when the port is configured in network loopback. This is useful for testing purposes. |
Passive port monitoring is supported through two shared bantam jacks located at the bottom of the trunk card front panel (see Figure 6). 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.
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.
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 Figure 14). 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.
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:
The following guidelines are recommended when working with any equipment that is connected to telephone wiring or to other network cabling:
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:
Caution Periodically check the resistance value of the antistatic strap. The measurement should be within the range of 1 and 10 megohms.

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.
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:
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.
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.
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:
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.)
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 Figure 14.
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 Figure 14.)
Step 9 Pull the trunk card straight out of the slot. Avoid touching the circuitry or any connector pins.
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."
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 Figure 14.)
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.
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 Figure 15.)
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.
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.
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:
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:
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:
To configure cable length, you must be in global configuration mode. Table 15 lists commands to help you configure your CT1 lines using the cablelength command.

Enter the controller cablelength long value using gain and pulse. |
This completes the trunk card installation procedure. Proceed to the section "Verifying and Troubleshooting the Installation" to verify 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 Table 1 earlier in this document.

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."
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.
Regulatory compliance and safety information for the Cisco AS5800 Universal Access Server is contained in the Regulatory Compliance and Safety Information document that shipped with your system.
