Release Notes for Cisco MICA Portware Version 18.104.22.168 on Cisco AS5x00 Universal Access Servers, Cisco 3600 Series, and Cisco 3700 Series
November 25, 2002
These release notes describe Cisco MICA Portware Version 22.214.171.124 with Cisco IOS software on Cisco AS5x00 universal access servers, and Cisco 3600 series, and Cisco 3700 series.
This document includes the following sections:
New Features for Version 126.96.36.199
The following features are new in this Version 188.8.131.52 maintenance release:
•V.110 "blind connect" feature—Allows compatibility with nonstandard clients (enabled by bit 9 in S-register S54). (CSCdr39887)
•S64—New S-register that allows support for finer granularity in modulation selection. (CSCdm94337)
•S71 and S72—Two new S-registers for control of the V.90 uplink maximum and minimum symbol rates, making them independent of the V.34 maximum and minimum symbol rate controls (S41 and S42). (CSCds40079)
Note S71 and S72 are read-only registers unless the DEBUGTHISMODEM command has been entered. You can use ATDEBUGTHISMODEMS71=4 using reverse telnet, or &F&D2DEBUGTHISMODEMS71=4 using a modemcap.
S64 can be set without entering the DEBUGTHISMODEM command.
Continued Feature Support for Cisco MICA Portware
Cisco MICA Portware Version 184.108.40.206 continues to support Version 220.127.116.11 features. Refer to the
Release Notes for Cisco MICA Portware Version 18.104.22.168 on Cisco AS5x00 Universal Access Servers.
S54 General Capabilities Register
S54 enables the following features:
•V.110 blind connect feature (bit 9)
•Error correction (EC) over parity (bit 6), enabled by default, so that the default value of S54 is 200 in Cisco MICA Portware Version 22.214.171.124 and above. This enables power control (CSCdk11008), 0.5 increment for SQ value (CSCdp40871), and the UART functionality/EC parity bit (CSCds35369)
The bit field values in S54 are as follows.
All general options disabled
Reserved for engineering use
Enable aggressive client capping
Force 4-point training
Enable power control
Enable EC quality checking
Cap receive (Rx) rate to 26,400 when detecting PCTEL Modem (CSCdm45403)
Enable Universal Asynchronous Receiver/Transmitter (UART) functionality (CSCdj92333)
Enable 0.5 increment for signal quality (SQ) value through S32 (CSCdr39887)
Digital signal processor (DSP) reset enable (CSCdp94025)
Enable V.110 blind connect (also called s&x) option to be the same as Cisco AS5200 (CSCdr39887)
Enables enhanced S detector (CSCdr65889)
1 See note on 4-point training below.
2 Enabled by default.
Note Although 16-point trainup is commonly used to tell modems which constellation size is being used when the modems are training up in phase 4, you can set trainup to 4-point if you are having problems syncing during training. 4-point training has fewer detection errors than 16-point training and is a more robust way of completing the full duplex train in V.34/V.90/K56Flex. 4-point trainup also allows you to operate reliably in a lower signal-to-noise ratio (SNR) environment. Use the S54=4 S-register as a debug tool.
Cisco MICA Portware Version 126.96.36.199 is backward compatible and runs on Cisco IOS software release 11.2P, 11.3T, 12.0, 12.1, and 12.1(5) with some feature limitations.
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.

Downloading Portware Modem Code
Cisco supports portware configuration using service processing element (SPE) configuration commands. The spe command allows portware to be downloaded to the SPE. The spe command is available for use with Cisco IOS Software Release12.0(4)XI1, 12.0(5)T, and higher.
Note If you enter the copy xxxx modem command on an access server running Cisco IOS Release 12.0(4)XI1, 12.0(5)T, 12.1(1), or higher, you are prompted to use the spe command.
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.188.8.131.52.bin.Router(config)# spe 1/0 1/9Router(config-spe)# firmware location flash:mica-modem-portware.184.108.40.206.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:
