Note
Many client modems used in Europe are known to have problems with the Modem on Hold (MOH)
feature. The vendors are aware of the issue and are working to correct it. If you are having trouble with
the Modem on Hold feature in Europe, it is suggested that the customer contact the client modem vendor
to verify that the modem complies with the telephony signaling for call waiting, caller ID, and 3-way
calling in their particular country. For more information, refer to the Configuring and Troubleshooting
V.92 Modems document on Cisco.com.
For a list of modems tested with Cisco MICA portware, refer to the Modem Interoperability List for V.34

Caveats for Cisco MICA Version 2.9.4.0
Caveats for Cisco MICA Version 2.9.4.0
This section describes known problems with portware Version 2.9.4.0. If a workaround is not provided,
a solution is being developed.
Note
The capabilities exchange feature for V.92 and V.44 is supported only in Cisco IOS Release 12.2(2)XB6
and higher. If you are using Cisco IOS Release 12.2(2)XA, 12.2(2)XB5, or earlier releases, you must
modify S54 in a modem cap to enable V.92 and V.44 operation. See the Release Notes for Cisco MICA
Portware Version 2.9.2.0 on Cisco AS5300 and Cisco AS5800 Universal Access Servers for details on
enabling V.92 using S54 for Cisco IOS software versions that do not contain this caveat (CSCdu81035).

Caveats for Cisco MICA Version 2.9.4.0
CSCdy17030—Do not mark DSP OOS for checksum error
A new s-register has been added to control whether or not the checksum failure message from the service
provider (SP) takes the modem Out-of-Service (OOS).
Table 2
Note
S82 [1] General Purpose Bit Mapped Register #2
Value
Description
0
Disable data queue overflow disconnect (CSCdx13950) and disable SP checksum
Out-Of-Service functionality (CSCdy17030).
1
(Default) Enable data queue overflow disconnect, disable SP checksum
Out-Of-Service (OOS) functionality.
2
Disable data queue overflow disconnect and enable SP checksum OOS functionality
3
Enable both data queue overflow disconnect and SP checksum OOS functionality.
To avoid decreasing your call success rate (CSR) with a ring no answer, do not enable the SP checksum
out-of-service (OOS) functionality for the Cisco AS5300 or Cisco AS5800 with Cisco IOS releases
prior to 12.2(2)XB7. CSCds09499 and CSCdy00812 need to be integrated in your Cisco IOS software
version before enabling the OOS functionality. Otherwise, Cisco IOS continues to allocate calls to the
out-of-service modem, which results in a Ring No Answer, which decreases your CSR.
CSCds09499 —Cisco AS5300:CSM should not allocate calls to busy or bad modems
CSCdy00812—Cisco AS5800:%MICA-3-NAK:NAK from modem 21 in state 50—payload 0x20 seen
CSCdw05174— Improvement for shorter Call Setup time needed for Cisco MICA
According to the V.8 specifications, Cisco MICA sends 400 ms of silence before the ANSback tone. It
was observed that there is no longer a need for staying in a 400 ms loop in the SP, because this silence
is inherently already there, due to the time spent elsewhere in the code.
The last bit of the GENERAL_PURPOSE_MAP (S54) has been allocated to give the you flexibility
whether to stay in this 400 ms loop or not. S54=32768 disables the 400 ms silence loop before the
ANSback tone. The default value of S54 (200) was not changes, so by default, the 400 ms silence loop
in Cisco MICA is still enabled.
CSCdv46797—Capability needed to reduce EC training time
This caveat was brought over from the 272x branch to the 291x branch. This change makes the length of
the TRN1d signal variable. As part of V.92, this signal is minimized to its shortest length while allowing
for the best connection. So if V.92 is enabled in Cisco MICA Portware Version 2.7.4.0, the code added
as part of CSCdv46797 is not used, regardless of the S74 setting. If V.92 is not enabled in 2.9.4.0, the
value of S74 can be used to shorten the TRN1d sequence.
See the Release Notes for Cisco MICA Portware Version 2.7.4.0 on Cisco AS5300 and AS5800 Universal
Access Servers and Cisco 3600 Series for further details regarding S74.
4-Point Training (S54=4) Debug Tool
There are two types of training, 4-point and 16-point. This information is provided by signal J in phase 3
of a modem connection. These size denotations tell the modems which constellation size is used when
the modems are training up (in phase 4). 6-point is used the most, but if you do not have a very clean
line, and you are having problems syncing up, you can set the constellation size to 4-point to see if you
are having problems during training. With 4-point, there are less detection errors (the points are spread
further away, so the detection is more lenient) than 16-point which has to be more precise.

Caveats for Cisco MICA Version 2.9.4.0
Additionally, 4-point training is a more robust way of completing the full duplex train in V.34, V.90, and
K56Flex. The regular train uses an 8-point constellation. When the line is noisy, the standard allows you
to switch down to a 4-point constellation, which allows you to operate reliably in a lower SNR
environment and complete training. We have broken this out into an S-register (S54=4) as a debug tool
for customer use.
See the Release Notes for Cisco MICA Portware Version 2.9.2.0 on Cisco AS5300 and Cisco AS5800
Universal Access Servers for more information about S54.

Downloading Portware Modem Code
Unresolved Caveats
•
CSCdx63339 —Cisco Mica fails to response to a MHreq sequence from the client modem.
•
CSCdx48205—Few modems are marked OOS and recover with auto configuration.
If you have an account on Cisco.com, you can also use the Bug Toolkit to find select caveats of any
severity. To reach the Bug Toolkit, log in to Cisco.com and click Service & Support: Software Center:
Cisco IOS Software: BUG TOOLKIT. Another option is to go to

Downloading Portware Modem Code
Download new portware by going to the following link:
http://www.cisco.com/cgi-bin/tablebuild.pl/mica
SPE Download Tasks
Cisco supports portware configuration using service processing element (SPE) configuration commands
and modem-pool commands. The spe command allows portware to be downloaded to the SPE.
To download modem portware using the spe command, enter the spe command, one configuration
command per line.
Step 1
Enter the spe command and subcommands, one configuration command per line:
Router# configure terminal
Router(config)# spe <slot>/<spe_begin> <slot>/<spe_end>
Router(config-spe)# firmware location system:/ucode/mica_port_firmware
Router(config-spe)# ^Z
For example, the following display shows a Cisco AS5300 SPE download to all modems in Slot 1 (that
is, all modems on a feature card containing ten 6-port modem modules). The modem code resides in the
Flash memory, and the modem code filename is mica-modem-portware.2.9.4.0.bin.
Router(config)# spe 1/0 1/9
Router(config-spe)# firmware location flash:mica-modem-portware.2.9.4.0.bin
Step 2
Copy the configuration from NVRAM into running RAM:
Router# copy running-config startup-config
Download occurs when the modems become available and shows the SPE firmware upgrade option
defined (default: busyout). The spe command generates NVRAM modem download and configuration
file entries.
Note
If the configuration is not saved as described above, download of the portware specified with the
spe command will not occur after the next reboot.
For detailed information on the spe command, go to the following link:
