Differences Between Firmware Versions 5.1.20 and 5.0.40

Firmware version 5.1.20 supports the following changes over version 5.0.40:

•Maintenance fixes on the previous baseline.

Differences Between Firmware Versions 5.0.40 and 5.0.20

Firmware version 5.0.20 supports the following changes over version 5.0.20:

•A workaround has been added to resolve an issue regarding Lucent based V.90 clients making excessive (could be as high as 50% depending on client and firmware revision) Normal mode connections when the client is set to defaults (S109=1). This client default will negotiate a V.90 or K56flex connection and allow the V.8bis handshake. V.90 was being advertised by the server modem by bit 1 in octet 15 of V.8bis (octet 15 sent as 83). The workaround is to clear this bit (octet 15 sent as 81) which will force a K56flex connection for Lucent clients ONLY. The current K56flex implementation does not have an issue of connecting in Normal mode, therefore connections will be more stable.

•A new register has been added. Bit 1 of :T127 controls this workaround. The default is zero (:T127=0). To disable the workaround, set :T127=2 (set bit 1).

---

Note   Forcing V.90 on the client by setting S109=2 would also disable this workaround while still allowing for V.90 connections. However, if V.90 connections are desired on Lucent modems they should be limited to below 50K for now.

---

•Also see the Revision History for bug fixes.

Differences Between Firmware Versions 5.0.20 and 3.3.20

---

Note   Firmware version 5.1.20 is the official FCS release and should be used instead of version 5.0.20.

---

Firmware version 5.0.20 supports the following changes over version 3.3.20:

•Firmware version 5.0.20 introduces support for the Draft ITU-T V.90 modulation at 28000 to 56000 bps in 1333 bps increments.

•Introduced %M4 to control V.90 modulation.

•Additional bug fixes were added to address issues in 3.3.20.

•Q2 was made the new default instead of Q0.

•:T114 defaults to 1 (clear bit 0) - So that Power boosting is no longer tied to A-law.

•-K2 is now the default instead of -K1.

•%G1 is not the default instead of %G0.

•When in a mu-law environment, the server modem will now force a Rockwell client modem set to A-law to go into mu-law.

Differences Between Firmware Versions 3.3.20 and 3.2.10

Firmware version 3.3.20 supports the following changes over version 3.2.10:

•3.3.20 is a maintenance release only with bug fixes added.

•No change in functionality was introduced.

•Fax manufacturer changed from Microcom to Compaq.

Differences Between Firmware Versions 3.2.10 and 3.1.30

---

Note   Firmware 3.2.10 not recommended for general use

---

Firmware version 3.2.10 supports the following changes over version 3.130:

•V.FC, FAX, Lucent K56flex, and Point of Sale (POS) support were added to the 3.2.10 release

Registers :t89, :t120, :t121 have been allocated to enable V.21/V.22 (300/1200) quick POS connections, error correction, pause for DCD to be true, and tone duration timers.

Known Problems with Firmware Version 5.1.20

This section describes known problems with this firmware release. If a workaround is not provided, the problem requires further investigation or a solution is being developed.

---

Note   Because V.90 technology is still a very new technology, all client modems should be upgraded to the latest code to ensure optimum performance and interoperability.

---

Known Issues

•Some country codes (such as UK) default to X3 preventing dialout from the Cisco AS5x00.

Cisco recommends using one of the following workarounds:

•Change the country code to X4 or set the modem to a country that defaults to X4. In the next release, all countries will default to X4.

•Add X4 in the server modemcap and apply with the modem autoconfigure.

•Insert X4 in the ATDT dial string as ATX4DT for the dialers.

•Under certain conditions, some V.34 clients may experience excessive Retrains and RREN during the connection. This is currently under investigation and should be resolved in the next release.

---

Note   See your Cisco engineering account representative or contact Cisco Connection Online if you experience any instances of excessive rate shifting.

---

•CSCdk48722—High failure to connect rate in Bell212 V.42bis.

•CSCdm29789—Dial Out Aborted with UK Country Code.

Minor Bugs

There are no minor issues in this release.

Notices

•FAX DialOut running with a minimum of Cisco IOS Release 11.3(6)T is possible with the fax firmware available in 3.2.10 and with Cisco IOS Release 11.3(1) and later. Cisco recommends Cisco IOS Release 11.3(4)T and later because there was a serious bug (CSCdj61765) with Abnormal Disconnects in earlier versions, which was fixed in Cisco IOS Release 11.3(4)T and later.

•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 (CSCdj74085), it is recommended that no modem startup be configured.

•Defaults for 5.0.xx:

•:T124 = 43

•:T110 = 44

•Disable K56flex/K56plus in the following 5.0.xx images:

•:T110 - 38 (decimal). Disables K56flex by disabling V.8bis negotiation.

•:T124 = 11 (decimal). Disables K56plus.

•You must change the country code setting if you are using your modems in a country other than those included in the USA country code. The USA country code is used for the following:

•Argentina

•Brazil

•Canada

•Chile

•China

•Columbia

•Hong Kong

•India

•Indonesia

•Korea

•Malaysia

•Mexico

•Peru

•Philippines

•Singapore

•Taiwan

•Thailand

See Changing Country Codes on Microcom Modems for configuration instructions. For later Cisco IOS releases, use the modem country microcom_hdms command as described in the "Modem Country Microcom_hdms" section in the Cisco publication, New and Changed Commands for the Cisco AS5300.

To see the list of the supported countries, use the modem country microcom_hdms. The following is an example of a list of supported countries:

Example: 

Router(config)# modem country microcom_hdms?

  argentina       Argentina

  australia       Australia

  austria         Austria

  belgium         Belgium

  canada          Canada

  chile           Chile

  china           China

  columbia        Columbia

  czech-republic  Czech/Slovak Republic

  denmark         Denmark

...

•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 Code for more information.

---

Note   The current Flash file system does not support removing individual files when the Flash is full. The Flash memory must be erased and then restored with the required files in order to free up Flash memory space. Therefore, it is highly recommended that copy operations to the boot Flash memory be limited to an absolute minimum.

---

Changing Country Codes on Microcom Modems

This section describes how to change the country code on Microcom modems in Cisco AS5200 Universal Access Servers running Cisco IOS Release 11.2(8)P, 11.2(9)P, 11.3(x), 11.3(T), 12.0(X), or 12.0(X)T. See Changing Country Codes on Microcom Modems—Cisco AS5300 for a description of country codes on the Cisco AS5300.

---

Note   With the introduction of Cisco IOS Release 11.2(10)P and Release 11.3(2)T for Cisco AS5200, the system supports changing country codes as described in Changing Country Codes on Microcom Modems—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

Configure the system as follows:

---

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:

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.

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. This section describes how to change the country code in the Cisco AS5300 Universal Access Server with the new command.

---

Note   The new command is updated for Cisco AS5200 access servers running Cisco IOS Release 11.2(10)P and Release 11.3(2)T.

---

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

5300(config)# 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 Appendix A, "Managing Modems," in the Cisco AS5300 Universal Access Server Software Configuration Guide. A complete explanation can be found in the Cisco publication, New and Changed Commands for the Cisco AS5300. See the Related Documentation section for more information.

---

Note   If you previously set the country code by editing the modemcap file (that is, by following the procedure described in Changing Country Codes on Microcom Modems), you must edit the file again to delete the country code entry (-i18z). Otherwise, you will not be able to use the modem country command.

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)

---

Note   Cisco IOS Release 11.3(1)T will use the two separate modem code files described above, and Cisco IOS Release 11.3(2)T will use the single modem code file described in the "Downloading Modem Code" section that follows.

---

The firmware is stored in the modem Flash memory, 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.

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

Figure 1 Copy Command Flow

For complete information, including the procedure for downloading the DSP software, see the "56K 12-Port Modem Cards for the Cisco AS5200 Universal Access Server" section in the Feature Guide for Cisco IOS Release 11.2(P). See the Related Documentation section for more information.

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 Cisco publication, Installing 56K 12-Port Modem Modules in Cisco AS5300 Universal Access Servers, that shipped with your 56K modem card. See the Related Documentation section for more information.

Fax DialOut

For information about Fax DialOut, see the Cisco DialOut Utility User Guide at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/access/dialout/index.htm

FAX DialOut is possible with the FAX firmware available in Cisco IOS Release 3.2.10 and with Cisco IOS Release 11.3(1). However there is a serious bug (CSCdj61765) with Abnormal Disconnects in Cisco IOS software. This is being worked on and a fix is expected shortly in an interim Cisco IOS Release 11.3(1.x).
