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 can handle all-analog or all-digital calls, or any combination of analog and digital calls. There is no need to build configurations that trade off analog and digital ports. All modem standards (V.34, V.42bis, and so forth) and features are supported, including dial-in and dial-out.
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 DC 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 router shelf supports the dial shelf and performs all routing and packet processing. The router shelf also houses the main system software images.
The dial shelf contains 14 slots and supports up to 10 modem cards that provide the following functions:

Modem Card Overview
The Cisco AS5800 Universal Access Server is equipped with a maximum of 10 modem cards that use Cisco's Modem ISDN Channel Aggregation (MICA) technology with upgradeable firmware. Each modem card plugs directly into the dial shelf backplane and has no external connections. Each modem card has 5 LEDs, which indicate modem card status.
The Cisco AS5800 Universal Access Server has the capability of terminating up to 1,344 modem connections when equipped with 10 double-density modem cards and 2 CT3 trunk cards.
Each double-density modem card contains 12 DMM SIMMS. Each DMM SIMM contains 12 digital modems.

LED Indicators
The double-density modem card has 5 LEDs (see ) to indicate modem card status.
Figure 5 Double-Density Modem Card Front Panel LEDs
During normal operation, all 5 LEDs light when the system is powered ON and the modem cards are ready. When the modem card CPU software image starts running, it shuts off all LEDs except the power LED. Modem card LEDs are listed in .
Modem Firmware
Modem card software is automatically downloaded to a modem card from the router shelf when you boot the system for the first time, or when you insert a modem card while the system is operating. When you insert modem cards while the system is operating, the system software recognizes the cards, and the router shelf downloads the required Cisco IOS image to the cards.
The modem firmware image (also known as portware) is bundled with the Cisco IOS modem card image. The firmware image uses an auto detect mechanism, which enables the modem to service multiple modem call types. A modem detects the call type and automatically configures itself for that operation.
The modems can be programmed to collect the ANI (calling number) and DNIS (called number) digits for caller identification information. This occurs only when the trunk cards are configured in Channel Associated Signaling (CAS) mode. The modem passes the ANI/DNIS information to the modem card software via a portware mailbox message.
The modem cards support the modem standards and features listed in :
Online Insertion and Removal
Your Cisco AS5800 Universal Access Server supports online insertion and removal (OIR). This feature allows you to remove and replace a feature card (trunk card or modem card) or dial shelf controller card while the system is operating, without affecting system operation.
Note
Each dial shelf controller card and feature card contains a female connector with which it connects to the system backplane. Each male backplane connector comprises a set of tiered pins in 2 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 2 ejector levers to be used when you install or remove a card, as shown in . The function of the ejector levers is to align and securely seat the card connectors in the backplane.
Do not force the dial shelf controller cards or feature cards into a slot, as you can damage the backplane connector pins if they are not aligned properly with the card connectors.
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.

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 card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and ejector levers are integral components of the carrier. Handle 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 the 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.
If no wrist strap is available, ground yourself by touching the metal part of the chassis.
Following are guidelines for preventing ESD damage:
•
•
•
CautionPeriodically check the resistance value of the antistatic strap. The measurement should be within the range of 1 and 10 megohms.

Removing and Replacing a Modem Card
Depending on your configuration requirements, you might need to replace or install new modem cards in your Cisco 5814 dial shelf. Although slot 0 through slot 11 accept modem cards, Cisco recommends you install modem cards in slot 2 through slot 11 and reserve slot 0 and slot 1 for trunk cards. (Trunk cards are required for call termination and can only operate in slot 0 through slot 5.)
Note
This section describes the steps to remove and replace a modem card from the dial shelf, and includes the following items:
•
•
If you are replacing a modem card with a new modem card of the same type in the same slot, the system software recognizes the new modem card interfaces and brings them up automatically. No additional configuration is needed.
If you are replacing an HMM SIMM modem card with a double-density modem card (or vice versa), you need to modify your running configuration file. Software configuration commands are defined in the section "Configuring the Modems" section.
For additional software configuration information, refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide that shipped with your system.
CautionTo avoid erroneous failure messages, remove or insert only one modem card at a time. Also, after inserting or removing a modem card, allow at least 15 seconds before removing or inserting another modem card so that the system can reinitialize and note the current configuration of all interfaces.
Note
The Busyout Command-Line Interface
To remove an individual modem without dropping calls or connections, you must first take the modem 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 0-11. The user designated value is generally configured during the initial setup configuration process.
lists the command lines used to busyout a modem card located in slot 2 of dial shelf 5. To input the busyout command, you must be in privileged EXEC mode.

This completes the modem card replacement procedure. Proceed to the section "Verifying and Troubleshooting the Installation."
Verifying and Troubleshooting the Installation
During normal operation, all 5 modem card LEDs light when the modem card is powered ON. When the modem card CPU software starts running, it shuts off all LEDs except the power LED. Later, LEDs light again as described in earlier in this document.
To complete the installation, verify the LEDs operate properly by observing the following LED states on the modem card:
•
If the power LED remains OFF, verify that the card is seated properly.
If the power LED lights on other modem cards in the dial shelf, try inserting the modem 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).
•
If the HCPU LED lights, the modem card has passed diagnostics and the system software is up and running.
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. If a programmed number of attempts to reload the software image fails, the dial shelf controller will power OFF the modem card and the HCPU light will shut off.
Verify that other cards in the dial shelf work properly. Verify the card is seated properly. Try inserting the card in a different slot. Verify that you are using the correct software image.
•
If the modem LED lights, all modem modules present on the card pass diagnostics.
If the modem LED fails to light, you have a faulty modem card. Return the modem card to the factory for a 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 Modems
The Cisco 5814 dial shelf is designed to recognize modem cards in slot 0 through slot 11 within the dial shelf chassis. If you are installing 10 modem cards in the dial shelf chassis, Cisco recommends you install modem cards in slot 2 through slot 11 and reserve slot 0 and slot 1 for trunk cards.
Note
If you are replacing a modem card in the same slot as the one you just removed, the system automatically recognizes the previous system configuration; no other configuration is needed.
