Example: 
Router(config)# modem country microcom_hdms?
  argentina       Argentina
  australia       Australia
  austria         Austria
  belgium         Belgium

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 some 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-Cisco AS5200 Running Cisco IOS Release 11.2(8)P, 11.2(9)P, 11.3(x), or 11.3(1)T

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), or 11.3(T). (The next section"Changing Country Codes on Microcom ModemsCisco AS5300" describes country codes on the Cisco AS5300 and other releases for the Cisco AS5200.)

Note Cisco IOS Release 11.2(10)P and Release 11.3(2)T for the Cisco AS5200 introduced support for changing country codes as described in the next section, "Changing Country Codes on Microcom ModemsCisco 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:

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:

Step 3 Specify the lines on which to apply the new modemcap. In the following example, lines 1 through 48 are specified:

Step 4 Turn on autoconfig to the selected lines:

Step 5 Exit line configuration mode, exit global configuration mode, and return to enable mode:

Step 6 Save the configuration changes to NVRAM:

Verify

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:

Router# show modemcap mcom_czech

Modemcap values for mcom_czech
Factory Defaults (FD):  [not set]
Autoanswer (AA):  [not set]
Carrier detect (CD):  [not set]

On-hook (ONH):  [not set]
Off-hook (OFH):  [not set]
Miscellaneous (MSC):  -i18z		
Template entry (TPL):  [not set]
Router#
Note The Miscellaneous (MSC) field is the only nondefault field set in the modemcap.

The following example shows verification from the AT command prompt. Make sure that you issue the AT command during the call. Note that the following display shows factory default settings for version 3.1.30 except for the country code.

Router# mod at 2/0

You are now entering AT command mode on modem (slot 2 / port 0).
Please type CTRL-C to exit AT command mode.

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.

Note The new command is available 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 the section "Setting Country Codes," in the Cisco AS5300 Software Configuration Guide appendix, "Managing Modems." A complete explanation is described in New and Changed Cisco IOS Commands for the Cisco AS5300.

Note If you previously set the country code by editing the modemcap file (that is, the procedure described in the section, "Changing Country Codes on Microcom ModemsCisco AS5200 Running Cisco IOS Release 11.2(8)P, 11.2(9)P, 11.3(x), or 11.3(1)T"), 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:

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 next section, "Downloading Modem CodeCisco AS5300."

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.

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 chapter, "56K 12-Port Modem Cards for the Cisco AS5200 Universal Access Server" in the Feature Guide for Cisco IOS Release 11.2(P).

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.

Dial Out

For information about Fax dial-out, 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 dial-out 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).
