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).
Firmware Release Notes Version 5.1.20 for Cisco Universal Access Server 56K 12-Port Modem Modules
3
Differences Between Firmware Versions 5.0.20 and 3.3.20
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:
6 Firmware Release Notes Version 5.1.20 for Cisco Universal Access Server 56K 12-Port Modem Modules
Severe Bugs
— 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.

Notices
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

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.

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.

Downloading Modem Code
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.
Figure 1 illustrates the flow of supported copy commands in the Cisco AS5200 running Cisco IOS
Release 11.2(9)P and 11.2(8)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 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).
