This release note lists status of the 56K modem firmware for Cisco's universal access server 12-port modules.
This document includes the following sections:
Table 1 lists feature content by modem firmware version.
| Firmware Version | Feature Content |
|---|---|
| 3.1.30 | Modulation
|
Firmware version 3.1.30 for 56K modems supports the following changes from version 2.2.8:
This section describes changes and bug fixes to all 56K modem firmware updates.
This section lists outstanding moderate and minor bugs.
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.
Take these steps:
Step 1 Enter global configuration mode:
Router> enable
Router# config term
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
| Country | Country Code | Country Code Displayed in Banner |
|---|---|---|
| Australia | 20 | 49 |
| Austria | 22 | 92 |
| Belgium1 | 23 | 67 |
| Czech/Slovak Republic1 | 18 | 91 |
| Denmark | 10 | 63 |
| Finland | 9 | 71 |
| France1 | 25 | 32 |
| Germany | 17 | 68 |
| Israel | 15 | 16 |
| Italy | 3 | 21 |
| Ireland | 24 | 97 |
| Japan | 13 | 14 |
| Netherlands | 5 | 04 |
| New Zealand | 11 | 55 |
| Norway | 8 | 72 |
| Poland | 19 | 93 |
| Portugal | 27 | 94 |
| Spain | 6 | 76 |
| South Africa | 16 | 69 |
| Sweden | 7 | 09 |
| Switzerland1 | 14 | 66 |
| UK2 | 2 | 12 |
| USA3 | 1 | 85 |
Step 3 Specify the lines on which to apply the new modemcap. In the following example, lines 1 through 48 are specified:
li 1 48
Step 4 Turn on autoconfig to the selected lines:
modem auto type mcom_czech
Step 5 Exit line configuration mode and global configuration mode:
exit
exit
Step 6 Save the configuration changes to NVRAM:
copy running-config startup-config
You can verify the changes to the modemcap in many ways. This section describes two ways: from the router command prompt and from the AT command prompt during the call.
The following example shows verification from the router command prompt:

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:
If you have questions or need assistance, refer to the last section in this document, "Cisco Connection Online."
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:
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 the section "Setting Country Codes," in the Cisco AS5300 software configuration guide appendix, "Managing Modems."
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:
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."
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.
