Differences Between Firmware Version 3.1.30 (56K Modems) and Firmware Version 2.2.8 (V.34 Modems)

Firmware version 3.1.30 for 56K modems supports the following changes from version 2.2.8:

• Full K56flex support for 32K to 56K connections speeds is available.
  
  
• Rockwell V.FC at 28800 bps, 26400 bps, 24000 bps, 21600 bps, 19200 bps, 16800 bps, and 14400 bps is not supported in this version in conjunction with K56flex support. See the notices section for more details.
  
  
• Part of the modem code, specifically the Digital Signal Processor (DSP) software, needs to be stored on the router's boot Flash. The modem's controller firmware is still stored on the modem's local Flash. See "Downloading Modem CodeCisco AS5200 Running Cisco IOS Release 11.2(8)P and 11.2(9)P" for more details.
  
  
• AT%M3 is the default after the K56flex DSP software is downloaded to the modems. This sets the default modulation to K56flex after the DSP is downloaded. Otherwise AT%M2 is the default with V.34 Annex 12 modulation (that is, when running from the DSP's ROM code).
  
  
• All 300 bps connections will be in normal modem regardless of AT\Nx. This is for decreased setup times. :T89=2 is the default with :T89=0 enabling MNP connections.
  
  
• The AT@E command display includes four additional parameters:
  
  
• • Robbed Bit Signaling Count
    
    
  • Digital Pad Presence (this variable has been introduced, but is not yet fully implemented)
    
    
  • DSP controller Rev
    
    
  • DSP Data Pump Rev
    
    
• AT\S now reports %Mn settings and split speeds.
  
  
• All the EQM function status parameters in the AT@E output have been removed except for the average EQM value.
  
  

Revision History

This section describes changes and bug fixes to all 56K modem firmware updates.

• N/A to initial release for 56K modems.
  
  

Outstanding Bugs

This section lists outstanding moderate and minor bugs.

Moderate

• (CSCdj16565)—High rate of no protocol connections in back-to-back call attempts.
  
  
• (CSCdj16062)—V.32 14.4K instead of 56K with Rockwell clients.
  
  
• (CSCdj17215)—Sometimes modem back-to-back test fails with NO CARRIER.
  
  
• (CSCdj26472)—No connection for V.FC modem when running from RAM.
  
  
• (CSCdj22693)—Forced V.34 12K and V.22 1200 bps connections are not stable.
  
  
• (CSCdj26548)—32 Kbps in 56K mode connects in 4800/31200 bps in V.34 mode.
  
  
• (CSCdj26157)—Called side modem reports as V22 for Bell 212 connection.
  
  
• (CSCdj26482)—MABP reports invalid TX speed for lower K56flex connections
  
  
• (CSCdj26484)—@E and show mod ver reports a different version number after the DSP is reloaded.
  
  
• (CSCdj26488)—RBS Counter & Digital Pad Detected status report not working
  
  
• (CSCdj26477)—ATI10/ATI11 is overwritten
  
  

Minor

• (CSCdj26069)—48K connections reported by clients but 56K modems report 50K.
  
  

Notices

• Cisco IOS Release 11.1(14)AA adds support for Microcom 56K 12-port modem modules. The 56K modems will work only in V.34 mode, up to 33.6 Kbps, using the latest 3.x.x modem firmware and ROM-based DSP code.
  
  

  The DSP software available on CCO should not be downloaded to the modem when using Cisco IOS Release 11.1(14)AA since it is not supported in this release. If the DSP software is downloaded, the modems will offer K56 functionality, but some IOS commands will show inconsistent results. Also, the DSP software in modem RAM will not be maintained over power cycles. Full K56Flex support requires the use of Cisco IOS Release 11.2(8)P and later.

• V.FC modulation is not supported in this version and as a result V.FC call attempts will be dropped. The reason for dropping the calls, instead of negotiating a V.32bis call, is that the ITU standard V.8 negotiation protocol cannot distinguish between V.FC and K56flex calls. Therefore the calls will drop as the client tries to set up a V.FC call while the server tries to setup a K56flex call.
  
  
• Only RAM based K56flex client modems are supported because the early ROM based K56flex implementations were not stable and are not currently supported by Rockwell.
  
  
• Because of a reliability problem with back-to-back tests (CSCdj17215), it is recommended that no modem startup be configured for this (3.1.30) version.
  
  
• You must change the country code setting if you are using your modems in a country other those included in the USA country code. The USA country code is used for: Argentina, Brazil, Canada, Chile, China, Columbia, Hong Kong, India, Indonesia, Korea, Malaysia, Mexico, Peru, Philippines, Singapore, Taiwan, and Thailand. See the next section, "Changing Country Codes on Microcom ModemsCisco AS5200 Running Cisco IOS Release 11.2(9)P and Lower," for configuration instructions.
  
  
• The K56flex DSP code must be stored in the Cisco AS5200 access server's boot Flash memory with the new 56K modems. See "Downloading Modem CodeCisco AS5200 Running Cisco IOS Release 11.2(8)P and 11.2(9)P" for the procedure.
  
  

Changing Country Codes on Microcom Modems—Cisco AS5200 Running Cisco IOS Release 11.2(9)P and Lower

This section describes how to change the country code on Microcom modems in Cisco AS5200 universal access servers running Cisco IOS Release 11.2(9)P and lower. (The next section describes country codes on the Cisco AS5300.)

The default country code is USA. The USA country code is also used for the following countries: Argentina, Brazil, Canada, Chile, China, Columbia, Hong Kong, India, Indonesia, Korea, Malaysia, Mexico, Peru, Philippines, Singapore, Taiwan, and Thailand. If you are using the modems in a different country, you must change the country code.

Configure

Take these steps:

Step 1   Enter global configuration mode:

Router> enable

Router# config term

Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#

 

Step 2   Edit the modemcap and specify the country code (-InZ) in the miscellaneous attributes field. Substitute n with one of the country codes listed in the "Country Code" column of Table 2. In the following example, the country code is set to "18" for the Czech/Slovak Republic:

Router(config)# modemcap edit mcom_czech misc -i18z

This concludes the procedure for changing the country code.

Country codes that are set manually, not following the procedure just described, will remain in effect until one of the following events occur:

• Another -I command is sent.
  
  
• The firmware is reloaded. (Firmware reloads will always reset the country code to USA.)
  
  
• The access server is power cycled.
  
  
• The access server is reloaded.
  
  

If you have questions or need assistance, refer to the last section in this document, "Cisco Connection Online."

Changing Country Codes on Microcom Modems—Cisco AS5300

Cisco IOS Release 11.2(9)XA and higher introduced a new command to change the country code.

To change the country code on Microcom modems in Cisco AS5300 universal access servers, use the following command from global configuration mode:

Router> modem country microcom_hdms country name

This command specifies the country to set the modem parameters (including encoding) for Microcom modems. The default is usa. Note that the access server will reset the Microcom modems for the command to take effect. For additional details on this feature including country codes, see the section "Setting Country Codes," in the Cisco AS5300 software configuration guide appendix, "Managing Modems."

Downloading Modem Code—Cisco AS5200 Running Cisco IOS Release 11.2(8)P and 11.2(9)P

In order to support K56flex modulation, Cisco AS5200 access servers running Cisco IOS Release 11.2(8)P and 11.2(9)P require two files that represent two modem code images: controller firmware and DSP software. Versions of the firmware and DSP software must be compatible. To determine compatibility, compare the filenames. For example, notice the similarity in the filenames for version 3.1.30 that follow:

• mcom-modem-fw-3.1.30-1.1.0.bin (controller firmware filename)
  
  
• mcom-modem-dsp-3.1.30-1.1.0.bin (DSP software filename)
  
  

The firmware is stored in the modem Flash, and the DSP software is stored in the access server's boot Flash memory. The procedure for downloading the DSP code is outlined below. It is important to note that the current Flash-based file system does not support the erasing or deleting of individual files.

The following figure illustrates the flow of supported copy commands in the Cisco AS5200 Running Cisco IOS Release 11.2(9)P and 11.2(8)P.

For complete information, including the procedure on how to download the DSP software, see the document, "Installing 56K 12-Port Modules in Cisco AS5200 Universal Access Servers."

Downloading Modem Code—Cisco AS5300

In order to support K56flex modulation, Cisco AS5300 56K 12-port modules require a single modem code file that contains two modem code images: controller firmware and DSP software.

In addition to residing on the 12-port module, 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. The 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 mapped modem code file in system Flash memory to automatically update the DSP software. 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. For details about how to download modem code and how to control the version used by the modems, see the section "Modem Code" in the Installing 56K 12-Port Modem Modules in Cisco AS5300 Universal Access Servers publication.
