Caveats for Cisco MICA Version 2.9.5.0

This section describes known problems with portware Version 2.9.5.0. 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).

4

Suppresses outbound calls from Cisco MICA (CSCea13007)


CSCea13007—Block outbound calls from Cisco MICA

In order to suppress outbound calls from being placed from Cisco MICA, the S82 bit 4 must be set in their modemcap. The default setting of S82 does not change the outbound call behavior of Cisco MICA.


Note To avoid decreasing your call success rate (CSR) with a ring no answer, do not enable the SP checksum 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 changed, 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.

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

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.2.9.5.0.bin.

Router(config)# spe 1/0 1/9
Router(config-spe)# firmware location flash:mica-modem-portware.2.9.5.0.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:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120t/120t7/spe1206t.htm
