November 25, 2002
These release notes describe Cisco MICA Portware Version 220.127.116.11 on Cisco AS5300 universal access servers with Cisco IOS Software Release 12.2(2)XA, 12.2(2)XB, 12.2(11)T, and higher. This is a V.92 initial release.
These release notes describe the following topics:
New Features for Version 18.104.22.168
Cisco MICA Portware Version 22.214.171.124 is a feature release that adds the following new features to existing Version 126.96.36.199 functionality:
•V.44 Lempel-Ziv-Jeff-Heath (LZJH) data compression algorithm—V.44 LZJH is a new compression standard based on Lempel-Ziv that uses a new string-matching algorithm that increases upload and download speeds to make Internet access and Web browsing faster. V.44 is enabled by default.
Refer to the V.44 LZJH Compression for Cisco AS5300 Universal Access Servers feature module for more information.
•V.92 Modem on Hold—V.92 Modem on Hold allows a dial-in customer to suspend a modem session to answer an incoming voice call or to place an outgoing call while engaged in a modem session. V.92 Modem on Hold is disabled by default. Refer to the
V.92 Modem on Hold for Cisco AS5300 Universal Access Servers feature module for more information.
•V.92 Quick Connect—V.92 Quick Connect speeds up the client-to-server startup negotiation, reducing the overall Internet service provider (ISP) connect time by avoiding some of the initial signal handshaking. V.92 Quick Connect is enabled by default. Refer to the
V.92 Quick Connect for Cisco AS5300 Universal Access Servers feature module for more information.
Cisco MICA Portware Version 188.8.131.52 is supported only with Cisco IOS Release 12.2(2)XA, 12.2(2)XB, 12.2(11)T, or higher releases. For Cisco IOS software release compatibility information, refer to the Compatibility Matrixes for Cisco AS5x00, Cisco 3600, and Cisco 3700 Platforms with Cisco MICA 6-Port and 12-Port Modem Module Portware.
The Cisco 3600 and Cisco 3700 series are supported in Cisco MICA Portware Version 184.108.40.206 through Version 220.127.116.11, but only Version 18.104.22.168 contains the bundled firmware for the Cisco 3600 and Cisco 3700 series.
Cisco MICA Portware Version 22.214.171.124 is supported on the following platforms:
•Cisco 3600 series
•Cisco 3700 series
Note Many client modems used in Europe are known to have problems with the Modem on Hold 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.

Downloading Portware Modem Code
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.
SPE Download Tasks
To download modem portware/firmware 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 terminalRouter(config)# spe <slot>/<spe_begin> <slot>/<spe_end>Router(config-spe)# firmware location system:/ucode/mica_port_firmwareRouter(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.18.104.22.168.bin.Router(config)# spe 1/0 1/9Router(config-spe)# firmware location flash:mica-modem-portware.22.214.171.124.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:
