Caveat Notes

This section provides specific caveat details from the "Resolved Caveats" section.

CSCdu43488---Capabilities exchange needs to be fully implemented.

Cisco MICA portware patch and above contains a feature that disables V.92 and V.44 if the Cisco IOS software being used does not support V.92 and V.44. Feature capabilities in Cisco IOS software are determined by the Capabilities Exchange operation, which occurs immediately after portware download.

If the Cisco IOS software does not support a certain portware feature (or if the software does not support Capabilities Exchange), you can use portware patch, which disables V.92, V.44, and the splitting of the speedshift and retrain counters. This functionality allows for backwards compatibility with older Cisco IOS software versions.

If needed, V.92 can be manually enabled using S54=16384. However, you should only do so if the Cisco IOS software version being used supports V.92 (for example, 12.2(2)XA and above or 12.2(2)XB and above). For more information, refer to the
Cisco AS5x00 and Cisco 3600 Cisco MICA 6-Port and 12-Port Modem Module Portware/Cisco IOS Software Compatibility Matrixes on

Portware that supports V.92 (for example, and V.92-capable Cisco IOS releases such as 12.2(2)XA and 12.2(2)XB did not support Capabilities Exchange (for further details, refer to the Cisco IOS DDTS, CSCdu81035—Support needed for MICA V.92 and split counters capabilities exchange. (This issue is being resolved in future V.92-capable Cisco IOS releases.)

Portware patch and above now supports Capabilities Exchange, but if the Cisco IOS release you are using does not, V.92 and V.44 are disabled unless you create the following modemcap:

&F&D2S54=16384S29=12S21=15 (plus any additional S54, Quick Connect, Modem On Hold, or other additional settings.)

Note S54=16384 needs to be set as the first S-register, and once it is set, the only way to disable V.92 is to download the portware again. As with past Cisco IOS software and portware features, it is not recommended that V.92 be re-enabled with S54 if you are not using a V.92-capable Cisco IOS software version such as 12.2(2)XA and above or 12.2(2)XB and above.

You can use portware and above with a non-V.92 capable Cisco IOS version if you only desire the added fixes listed in the Caveat Notes section and you do not re-enable V.92 (unless you upgrade your Cisco IOS software to 12.2(2)XA or 12.2(2)XB). However, these features might send link information and statistics that the Cisco  IOS software might not understand. This might result in invalid messages being printed out by Cisco IOS software (a cosmetic issue), but the portware will work fine.

S54 (200) General Capability Register (bit-mapped)

The S54 register defaults to S54=200 in Cisco MICA Portware Version and above. This enables Power Control (CSCdk11008), 0.5 increment for SQ value (CSCdp40871), and the UART functionality/EC parity bit (CSCds35369).

The following values are supported in this portware release:

S54 Value


All general options disabled.


Reserved for engineering use.


Enable aggressive client capping.


Force 4-point training (see the 4-Point Training (S54=4) Debug Tool section).


Enable power control. Enabled by default.


Enable EC quality checking.


CAP Rx rate to 26400 when detecting PC-Tel modem (see CSCdm45403).


Enable UART functionality (see CSCdj92333). Enabled by default.


Enable 0.5 increment for SQ value using S32 (see CSCdp40871). Enabled by default.


DSP reset enable (see CSCdp94025).


Enable V.110 S&X option to be the same as Cisco AS5200 (see CSCdr39887).


Enable enhanced S detector (see CSCdr65889).


Enable V.92 and V.44 (see Cisco MICA DDTS, CSCdu43488, and Cisco IOS DDTS, CSCdu81035).

CSCdv02248—Fail to train on client #YJSDPN

This issue was caused by a Telco echo suppressor being re-enabled, which would normally be disabled throughout a given call. However, this particular PCMCIA client modem gave a nearly 4-second delay before trying to re-train. If Cisco MICA also kept silence during that delay, the Telco echo suppressor would be re-enabled, and the modems would not properly fall back to V.34.

The problem was resolved by having Cisco MICA continually transmit V.90 bits instead of silence while waiting for the re-train request from this particular client modem.

So that other client modems are not impacted by this issue, a DSP debug configuration bit has been added to enable the fix. Create a modemcap that includes the following to set this configuration bit and turn on the fix:


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.

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.

Downloading Portware Modem Code

Download new portware by going to the following link:

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.

Router(config)# spe 1/0 1/9
Router(config-spe)# firmware location flash:mica-modem-portware.

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:
