Product Overview

The 56K 12-port modem module (Figure 1) uses Rockwell's K56Flex technology. The modem can send data at up to 56 kbps and receive data at up to 33.6 kbps. However, the actual speed that you can achieve with the modem depends on the condition of your local telephone network.


Note   Actual speeds vary depending on line conditions. Due to FCC limitations, speeds in the U.S. are less than 56 kbps.


Figure 1 56K 12-Port Modem Module

Prerequisites

The following prerequisites apply to the 56K 12-port modem module:

K56Flex-compatible modems must be present at both ends of a digital connection in a digital network. If not, 56-kbps throughput cannot be achieved. The speed will fall back to 33.6 kbps.

Only one analog loop can be in the end-to-end communications path.

You cannot have any A-law to µ-law conversions, which exist at some international gateways.

Cisco IOS Release 11.2 (9)XA, 11.2 (10)P, or higher.

Safety Recommendations

Follow these guidelines to ensure general safety:

Keep the chassis area clear and dust-free during and after installation.

Keep tools away from walk areas where you or others could fall over them.

Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves.

Safety with Electricity


Warning   

Read the installation instructions before you connect the system to its power source.



Warning   

Ultimate disposal of this product should be handled according to all national laws and regulations.



Warning   

Only trained and qualified personnel should be allowed to install or replace this equipment.



Warning   

To ensure your safety and the safety of others, be sure the power is OFF and the power cord is unplugged before working on the router.



Warning   

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.


Follow these guidelines when working on equipment powered by electricity:

Locate the emergency power-OFF switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power OFF.

Disconnect all power before doing the following:

Installing or removing a chassis

Working near power supplies

Do not work alone if potentially hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn OFF power to the system.

If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.


Caution   
For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm).

Installation Overview

The use of 56K modems introduces a new step for installing and configuring modem software. To use 56K modems, you must first install the modem code file into the Cisco AS5300 system Flash memory. The following steps provide an overview of the installation process:

1 Verify that the Cisco AS5300 is running Cisco IOS Release 11.2 (9)XA, 11.2 (10)P, or higher.

2 Install the 56K 12-port modem modules, as described in the section "Installing 56K 12-Port Modem Modules."

3 In some circumstances, download new modem code. Depending on your configuration, you can download the modem code from an external file or from the default modem code bundled with Cisco IOS software. These options are explained in "Modem Code."

4 Configure the Cisco AS5300 to support the 56K 12-port modem modules, as described in the section "Configuring 56K 12-Port Modem Modules."

Installing 56K 12-Port Modem Modules

You must install 56K 12-port modem modules in a Microcom carrier card, which is not included with this kit. The carrier card, shown in , is a wide card with two slots in which you can install up to two 56K 12-port modem modules (or other supported port modules). You can install 56K 12-port modem modules with any combination of other supported port modules.

Figure 2 Microcom Carrier Card

Required Tools

You will need the following tools:

ESD-preventive wrist strap

Medium-size flat-blade screwdriver (1/4 in. [0.625 cm])

Installation

To install the 56K 12-port modem module, refer to and take these steps:

Step 1 Attach an ESD-preventive wrist strap.

Step 2 Power OFF the access server.


Caution   
The modem modules are not hot-swappable (that is, you cannot remove or install them when the access server power is ON). Be sure to power OFF the access server before installing or removing modem modules. Failure to do so can damage the access server.

Step 3 Remove all interface cables from the back panel of the access server.

Step 4 Remove the blank cover or modem module installed in the carrier card.


Note   If the carrier card is already installed in the access server, you can install 56K 12-port modem modules in the card without removing the carrier card from the access server chassis.


Step 5 Remove the 56K 12-port modem module from the ESD-preventive shipping material.

Step 6 Slide the 56K 12-port modem module into the carrier card slot until it is seated completely.

Step 7 Tighten the two captive screws on the 56K 12-port modem module to secure it to the carrier card.

Figure 3 56K 12-Port Modem Module Installation (Carrier Card Shown)

If you have questions or need assistance, refer to the section "Cisco Connection Online" at the end of this document. Otherwise, proceed to the section, "Configuring 56K 12-Port Modem Modules."

Modem Code

The 12-port module uses the following modem code images in a single-file format:

Modem controller firmware, which resides in modem Flash memory

DSP software, which resides in modem RAM

Modem code also resides on the access server: one version is bundled with Cisco IOS software, and another version can exist in system Flash memory. This modem code residing in the access server is a single file comprised of the modem firmware image combined with the DSP software image.

After power on, Cisco IOS software uses its bundled modem code file or the existing modem code file in system Flash memory to automatically update the DSP software and modem firmware on a given modem.

When you install a new 12-port module, Cisco IOS software examines the following versions of modem code:

Cisco IOS bundled modem code

Firmware in modem Flash memory

Any mapped modem code file in system Flash memory

Then, Cisco IOS software ensures that the system uses matching DSP software and modem firmware—which may include overriding the current firmware on the modem. In some circumstances you may decide to manually update the modem code after the automatic download process completes.

Deciding on an Update Strategy

Because of the possibility of multiple versions of modem code and the way Cisco IOS software process these versions, Cisco suggests that you decide between the following two strategies:

Always allow Cisco IOS software to use the bundled modem code

Always control the version of modem code used by the modules, independent of Cisco IOS selections

To help with the decision, shows a hypothetical release process. We recommend that you use the modem code bundled with Cisco IOS software because it is the easier strategy and enables you to take advantage of new modem code whenever you upgrade your Cisco IOS software. You can also control the modem code by reverting to previous versions by using the copy command as discussed later.

Figure 4 Release Timeline for Cisco IOS Software and Modem Code

Modem Code Scenarios

provides some typical scenarios that occur when you add or replace a 12-port module. provides scenarios that occur when you upgrade Cisco IOS software or modem code.

Table 1 Modem Code Scenarios—Hardware Installation

Scenario
Update Process

You replace an existing 56K 12-port module with a module that contains newer modem code.1

Option 1—Accept the version of modem code selected by Cisco IOS software.

Option 2—Upgrade modem code to a different version.

Option 1—No action needed.

Option 2—Copy the desired version of the modem code file to system Flash memory, then copy that file to the integrated modems on the 12-port module. See "Using the Modem Code from an External File," page 12.

You replace a V.34 12-port module with a 56K 12-port module.2

Option 1—Accept the version of modem code selected by Cisco IOS software (this is the bundled version).

Option 2—Upgrade the modem code to a different version.

Option 1—No action needed.

Option 2—Copy the desired version of modem code file to system Flash memory, then copy that file to the integrated modems on the 12-port module. See "Using the Modem Code from an External File," page 12.

1 Because Cisco IOS software maps modem code (either the bundled Cisco IOS version or a system Flash memory version) to a given slot/port and not the physical modem, Cisco IOS software will automatically load the modem code mapped to the previous module. For more information, see the description of mapping in Table 4 on page 11.

2 Cisco IOS software recognizes that the modem code (which is mapped to the previous module) as invalid, so it uses the bundled version.


Table 2 Modem Code Scenarios—Cisco IOS Software or Modem Code Upgrades

No.
Scenario
Update Process

1

You update Cisco IOS software, and you decide to use the version of modem code selected by Cisco IOS software.

Update Cisco IOS software.

No further action needed—Cisco IOS software automatically downloads either its bundled version or a mapped version from system Flash memory.1

2

You update Cisco IOS software, and you decide not to use the modem code selected by Cisco IOS software.

Update Cisco IOS software.

Copy the desired version of modem code file to system Flash memory, then copy that file to the integrated modems on the 12-port module.

See "Using the Modem Code from an External File," page 12.

3

The modems are running a version of modem code from system Flash memory that is different than the version bundled with Cisco IOS software. You decide to revert to the bundled version.

Use the Cisco IOS command copy system:/ucode/filename modem command (or, for Cisco IOS releases earlier than 11.3AA or 12.0, the copy ios-bundled modem command). To view a list of microcode filenames, use the dir system:/ucode command.

See "Using the Modem Code Bundled with Cisco IOS Software," page 17.

4

Cisco releases new modem code, which is a later version than the version currently running on the modems. You decide to use Cisco's newest modem code.2

Copy the desired version of modem code file to system Flash memory, then copy that file to the integrated modems on the 12-port module.

See "Using the Modem Code from an External File," page 12.

1 In part, Cisco IOS software bases this decision on the last copy command issued. For more details about mapping, see Table 4 on page 11.

2 Cisco ships new modem code on a disk packed with the 12-port module.

provides a list of terms and commands and a description of how they are used in the modem code update process.

Table 4 Modem Code Terminology 

Term
Description

Modem firmware

Modem controller firmware that resides in modem Flash memory.

DSP software

DSP controller software that resides in modem RAM. Cisco IOS software transfers a version of DSP software to modem RAM on each reboot.

Modem code

Two images:

Modem controller firmware

DSP software

These images reside separately in the modems and as a single-file version in the access server's system Flash memory.

System Flash memory can contain several versions of modem code: a version bundled with Cisco IOS software and multiple versions that resulted from previous copy tftp flash commands.

copy tftp flash mcom-modem-code-x.x.x.bin
command

Places a copy of the modem code in system Flash memory.

copy flash modem command

Transfers the copy tftp flash version of modem code to the modems. This command transfers the modem firmware file to modem Flash memory and the DSP software file to modem RAM.

Maps the system Flash memory version to the modems.

copy system:/ucode/filename modem command
(or, for Cisco IOS releases earlier than 11.3AA or 12.0, copy ios-bundled modem command)

Instructs the modems to use the version of modem code bundled with Cisco IOS software. This command does not affect any existing versions of modem code that reside in system Flash memory.

After one such command, future Cisco IOS upgrades will potentially result in the downloading of new Cisco IOS bundled firmware to the modems. (If the new Cisco IOS image contains the same modem code as the old one, no new code will be downloaded to the modems.)

Maps the bundled Cisco IOS software version to the modems.

Mapping

The copy commands map a specific version of modem code to a group of modem slots/ports. The copy system:/ucode/filename modem (or, for Cisco IOS releases earlier than 11.3AA or 12.0, copy ios-bundled modem) command maps the slots/ports to the bundled version, and the copy flash modem command maps the slots/ports to a specific modem code file located in system Flash memory. Cisco IOS software uses the mapping to determine which version of modem code should be downloaded to the modems. If Cisco IOS software finds no mapping or invalid mapping, it downloads the bundled version.


Using the Modem Code from an External File

Use the procedures in this section to transfer modem code from Cisco Connection Online (CCO) to the integrated modems on the 12-port module. The procedure consists of the following tasks:

Download the modem code to a TFTP server

Copy the modem code from the TFTP server to the modems

Downloading Modem Code to a TFTP Server

You can download the single file (mcom-modem-code-x.x.x.bin) to a TFTP server on your LAN two ways:

Using an Internet browser

Using a traditional FTP application

Download Modem Code to a TFTP Server—Method 1, Use an Internet Browser

Log in to Cisco's Software Center at the following URL to download the modem code file. You must log in as a Cisco registered user. (If you are not a registered user, note that Cisco provides modem code on a disk when are updates are necessary. This disk is shipped with the 12-port module.)

After downloading to your desktop computer, you must transfer it to a TFTP server on your network using an FTP application.

remote: mcom-modem-code-3.1.30.bin
385503 bytes received in 3.6 seconds (1e+02 Kbytes/s)


Step 7 Quit your terminal session:

ftp> quit
Goodbye.


Step 8 Verify that you successfully transferred the modem code file to your local directory:

server% ls -al
total 596
-r--r--r-- 1 377112 Jul 10 18:08 mcom-modem-code-3.1.30.bin
server% pwd
/auto/tftpboot


Step 9 If you have not already done so, transfer this file to a local TFTP server that your Cisco AS5300 can access.


Note   In some cases, Cisco ships modem software on a disk. To use this software, first upload the software to your TFTP server, then download the software to the modem using the method described in the next section "Copying the Modem Code File from a Local TFTP Server to the Modems."

If you loaded Cisco IOS software from a feature pack CD using Router Software Loader (RSL), note that the CD contains a TFTP server program for PCs using Windows 95. Run the server program from the directory where you installed the RSL program. Remember to set the Root directory to the directory where the AS5300 56K modem code is located. RSL is also available on CCO in the software library in the Access Products section.


Copying the Modem Code File from a Local TFTP Server to the Modems

The procedure for copying the modem code file from your local TFTP server to the access server system Flash memory is a two-step process. First, transfer the code to the access server. Then, transfer the code to the modems.

These two steps are performed only once. After you copy the modem code file into system Flash memory for the first time and map that file to a specific modem using the copy flash modem command, you do not have to perform these steps again. Because the DSP software runs from modem RAM, the Cisco IOS software must automatically copy the DSP software to each modem each time the access server power cycles.


Note   A list of download failure reasons and recommended actions is provided in Table 5 on page 18.



Step 1 Copy the modem code file from your TFTP server to the access server's system Flash memory using the copy tftp flash command. Cisco IOS software prompts you with a sequence of questions such as name/address of the TFTP server and the filename to be copied. Answer all of the prompts according to your configuration. The following example shows a typical download.

5300# copy tftp flash

Note   On the display, notice that the command copies the concatenated modem code file, mcom-modem-code-3.1.30.bin. When the DSP software and modem firmware download is complete, the display reports the modem firmware component, MNPClass10K56flexModemRev3.1.30/85, was downloaded to the modems.


If you want to verify that the DSP software and modem firmware copied to the modems, use the show modem version command. In this example, modems 2/12 through 2/23 are loaded with the modem controller firmware and DSP software:

5300# show modem version

     vendor_banner= Microcom MNP10 K56 Modem


Now the modems are equipped with code. The modems are configured to transmit at speeds up to 56 kbps. Each time the access server is power cycled, Cisco IOS software automatically loads the modems with the modem code in system Flash memory. If you erase the modem code file from system Flash memory, the Cisco IOS default modem code (that is, the bundled modem code) will be automatically downloaded to the modem.

Using the Modem Code Bundled with Cisco IOS Software

If you already have a version of modem code in the Flash memory on your access server, and you upgrade to a Cisco IOS release that includes newer modem firmware, only the modems that are mapped to the bundled Cisco IOS version are updated. In order to set the modem firmware mapping to the firmware version bundled with Cisco IOS software, enter the following command:

5300# copy system:/ucode/filename modem 

Note   For Cisco IOS releases earlier than 11.3AA or 12.0, use the copy ios-bundled modem command.



Note   This command does not affect any existing modem code that resides in system Flash memory in case you later want to revert to it. If you decide to delete the code from system Flash memory, remember that all files in system Flash memory will be deleted, therefore save and restore any important files (for example, the Cisco IOS software image).


As a result of the copy system:/ucode/filename modem (or copy ios-bundled modem) command, future Cisco IOS upgrades will potentially result in the mapping of new Cisco IOS bundled firmware to the modems. (If the new Cisco IOS image contains the same modem code as the old one, no new code will be downloaded to the modems.)


Note   To determine the version of modem code bundled with your Cisco IOS software, refer to the Cisco IOS release notes shipped with the chassis.


Download Failure Reasons and Recommended Actions

During the modem code download process, you may receive an error message if the download fails.

Table 5 Download Failure Reasons and Recommended Actions 

Error Message
Description
Recommended Action

%%ERROR: Modem <slot/port>, Modem Firmware file is not valid for modem type.

The specified modem firmware is not compatible with the target modem. For example, V.34 modems cannot be upgraded with 56K firmware. If you have a bank of non-56K modems in the access server and specify the all option in the copy tftp modem command, this error message will appear and not download 56K firmware where appropriate.

Verify that you are copying 56K modem firmware to 56K modems. Also use the show modem command to verify that you specified the correct slot/port or range.

%%ERROR: Modem <slot/port> currently being downloaded.

The modem code is currently downloading to the 56K modems.

The first download will containue without interruption, and the second download is aborted.

%%ERROR: Modem <slot/port>, download functions not initialized.

The modem code cannot be downloaded to the specified modem.

Use the show modem command to verify that you are downloading to a supported 56K modem.

%%ERROR: Modem <slot/port> is held in reset.

The specified modem is held in reset mode. The DSP software will not download to this modem.

Take the modem out of reset mode, then copy the DSP software again.

%%ERROR: NVRAM write for DSP download filename entry failed.

There is an NVRAM table problem.

Reissue the copy tftp flash command and copy the DSP file again.
