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, Personal Computer Memory Card International Association (PCMCIA) Flash memory cards, cables, and Cisco IOS software. The dial shelf feature cards and host router shelf communicate via a proprietary dial shelf interconnect cable.

The dial shelf contains 14 slots (numbered 0 through 13 on the backplane). The dial shelf can support up to 10 modem cards, 2 trunk cards, and 2 dial shelf controller cards. Only slot 0 through slot 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 6 slots.

---

Note   The Cisco AS5800 access server currently only supports a maximum of 2 CT1 trunk cards, 1 CT3 trunk card, or 1 CT1 and 1 CT3 card installed in any of the dial shelf slots 0 through 5.

---

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

CT3 Trunk Card Overview

The CT3 trunk card contains an onboard M13 multiplexer, which multiplexes 28 separate T1 lines into a single T3 line. Each CT3 trunk card installed in the Cisco 5814 dial shelf contains all necessary functionality to terminate link signaling and incoming digital calls.

shows the CT3 trunk card components.

Figure 3 CT3 Trunk Card

Each CT3 trunk card performs the following functions:

•Provides physical termination for up to 672 sessions.

•Provides digital termination for up to 256 DS-0 connections (calls) using onboard HDLC controllers. Note that the D-channel of a PRI consumes a single channel of an HDLC controller.

•Removes framing and embedded signaling bits (or inserts them depending on the direction of the flow), demultiplexing the calls. The framer CPU sends the data stream to onboard time-division multiplexing (TDM) resources, which break out each call and passes each call to an appropriate call termination resource. Digital or ISDN-originated calls are terminated onboard the CT3 trunk card on HDLC controllers.

---

Note   Each D-channel consumes an HDLC controller.

---

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.

•Responds to time-sensitive signaling. Each CT3 trunk card can supply two clocks from any two of its 28 ports. You can assign priorities to these clocks or accept the default values assigned by the software.

•Processes counting information for performance monitoring.

•Supports online insertion and removal (OIR), a feature that allows you to remove and replace a trunk card 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 CT3 lines on that card are dropped. Calls being handled by other trunk or modem cards, however, are not affected. For more information, see the "Online Insertion and Removal" section.

Clocking

All Cisco AS5800 access server trunk cards use the same transmit clock. This clock can originate from several sources, which are as follows:

•TDM clock source—A priority value between 1 and 50 that is applied to a clock source using multiple clock sources.

•External clock source—A clock source external to the access server.

Default priority values for clocking are based on the following:

•Clocks are prioritized by slot number (slot 0 to slot 5). 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 global configuration, and select a maximum of 2 clocks per trunk card.

If you configure fewer than 2 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.

CT3 Clocking

CT3 trunk cards are usually attached to an external device, such as a Digital Access and Cross Connect System (DACS) or Add-Drop multiplexer (ADM). This point-to-point link requires a single clock source to which the CT3 link is timed. You must determine whether you want the CT3 trunk card or external device as the primary clock source and configure it accordingly during the software configuration process, which is discussed later in this document.

CT1 Clocking

The CT3 trunk card has 28 T1 framers that always get their clock from the line. As a result, the configuration of T1 clock sources is not allowed.

LED and Alphanumeric Indicators

The CT3 trunk card front panel is designed with an alphanumeric display to provide trunk card status, as shown in .

Figure 5 CT3 Trunk Card Front Panel LED and Alphanumeric Indicators

CT3 Trunk Card Specifications

Using the Test Port

The CT3 trunk card front panel is designed with an alphanumeric display to provide trunk card status and port level monitoring information (see ).

Test port functionality is supported by Cisco IOS Release 12.0(6)T and later releases.

Trunk Card Bantam Jacks

The test port is a set of bantam jack connectors located at the bottom of the CT3 front panel (see ). The bantam jacks allow the connection of an external test device (for example, a FIREBERD test device) to test any of the 28 individual T1 circuits in drop-insert mode or to monitor the individual T1 circuit in monitor mode.

•In monitor mode, you can only monitor the ingress side of the T1 line. The T1 line being monitored is not disrupted, and the line maintains its HDLC and modem connections through TDM.

•In drop-insert mode, the T1 line is dropped out of service. To prevent accidental use of the pushbutton in drop-insert mode, use the test trunk drop-insert privileged EXEC command to disable the drop-insert mode on the specified T3 controller. See the next section "Drop-Insert Mode" for details.

Drop-Insert Mode

The test trunk drop-insert privileged EXEC command is used to enable or disable drop-insert mode on a T3 controller. When the system initially boots up, the drop-insert mode is disabled on all T3 controllers.

To drop a particular T1 line to the test port, follow these steps:

---

Step 1 Enable drop-insert mode by entering the test trunk drop-insert on privileged EXEC command as follows:

5800# test trunk drop-insert on shelf/slot/unit

---

Note   The shelf/slot/unit refers to the CT3 controller.

---

Step 2 Push and quickly release the pushbutton below the LED to toggle to the port number. The pushbutton is labeled monitor # in .

---

Note   You must release the pushbutton within 2 sec to advance through the port numbers (from 1 to 28). After port 28, the display returns to port 1.

---

Step 3 Push and hold the pushbutton for 2 or more sec.

The letter "D" (indicating drop-insert) is displayed in the front panel LED, indicating that the particular T1 line has been dropped to the test port.

---

Note   To select another port number, press the pushbutton again and hold it for 2 or more sec. You can now toggle to another port number.

---

Step 4 Disable the drop-insert mode after testing the T1 lines. We recommend that you disable drop-insert mode to prevent accidental use of the pushbutton on the CT3 board.

To disable drop-insert mode, enter the test trunk drop-insert off privileged EXEC command as follows:

5800# test trunk drop-insert off shelf/slot/unit

Monitor Mode

To monitor a particular T1 line at the test port, follow these steps:

---

Step 1 Verify if drop-insert mode is disabled on the CT3 controller by entering the show command as follows:

5800# sh controller t3 shelf/slot/unit

The following is sample output from the sh controller t3 command if drop-insert mode is disabled:

as5800# show controller t3 1/1/0

T3 1/1/0 is up.

Applique type is Channelized T3

No alarms detected.

Note   If the display shows "Drop-insert is enabled," repeat Step 4 on page 13.

---

Step 2 Push and quickly release the pushbutton below the LED to toggle to the port number. The pushbutton is labeled monitor # in .

---

Note   You must release the pushbutton within 2 seconds to advance through the port numbers (from 1 to 28). After port 28, the display returns to port 1.

---

Step 3 Push and hold the pushbutton for 2 or more seconds.

The letter "M" (indicating monitor) is displayed in the front panel LED, indicating that you can monitor the particular T1 line at the test port.

---

Note   To select another port number, press the pushbutton again and hold it for 2 or more sec. You can now toggle to another port number.

---

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 T3 trunk card while the system is operating, without affecting system operation.

---

Tips

This section describes system component mechanical functions 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 "Replacing or Installing a Trunk Card," page 18 for specific procedures regarding the CT3 trunk card.

---

Each card contains a female connector that connects to a male connector on 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 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.

Figure 8 Card Ejector Levers

---

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.

---

---

Tips

To avoid erroneous messages, you must allow at least 15 sec 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. Cisco recommends the following safety guidelines when working with any equipment that connects to electrical power or telephone wiring:

•Locate the emergency power-off switch for the room you are working in 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

Cisco recommends the following guidelines when working with any equipment that is connected to telephone wiring or 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 megohm.

Replacing or Installing 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 only recognizes trunk cards installed in the first 6 slots, you must install trunk cards in slots numbered 0 through 5 on the dial shelf backplane.

---

Note   The online insertion and removal feature allows you to install and remove a trunk card without powering OFF system power. Refer to the section "Online Insertion and Removal," page 14 for a description of OIR.

---

This section describes the steps to remove and replace a trunk card from the dial shelf, and includes the following items:

•Busyout Command-Line Interface

•Tools and Parts Required

•Removing a Trunk Card

•Installing a Trunk Card

•Connecting Cables

•Verifying and Troubleshooting the Installation

•Configuring Your CT3 Trunk Card

If you are replacing a trunk card with a new trunk card of the same type in the same slot, the system software recognizes the new trunk card interfaces and brings them up automatically. No additional configuration is needed.

If you are replacing a CT1 trunk card with a CT3 card (or vice versa), you need to modify your running configuration file. Software configuration commands are defined in the section "Configuring Your CT3 Trunk Card," page 25.

For additional software configuration information, refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide that shipped with your system.

Busyout Command-Line Interface

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 recognized in slot 0 through slot 5. The user designated value is generally configured during the initial setup configuration process.

lists the command lines to busyout a trunk card located in slot 0 of dial shelf 5. To input the busyout command, you must be in privileged EXEC mode.

Table 3 Disabling a Trunk Card from Dial-In Services

Step	Command	Description
1	AS5800-1# enable Password: password AS5800-1#	Enter the enable command. Enter your password. You are in privileged EXEC mode when the prompt changes to AS5800-1#.
2	AS5800-1# busyout 5/0 AS5800-1#	Disable a trunk card gracefully from dial-in services using the busyout command.

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.

---

Caution   

To avoid erroneous failure messages, remove or insert only 1 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.

---
