Release Notes for Cisco MICA Portware Version 188.8.131.52 on Cisco AS5x00 Universal Access Servers
November 25, 2001
These release notes describe Cisco MICA Portware Version 184.108.40.206 with Cisco IOS software on Cisco AS5x00 universal access servers and Cisco 3600 series routers.
The features supported in Cisco MICA Portware Version 220.127.116.11 provide higher initial transmit connect speeds, increased connection stability, better throughput, and higher connect success rates (CSRs) than previous Cisco MICA portware versions.
This document includes the following sections:
New Features for Version 18.104.22.168
The following feature is new in this release.
Dial modifiers X, W, and (,) are now supported where the following is true.
The W and (,) modifiers work similarly to those used in a standalone analog modem.
In the following example dial string, the portion of the string before the X is dialed for the given line type used in your configuration. All digits after the X generate the appropriate DTMF tones:atdt5551234x,,567
For more information about the X, W, and (,) dial modifiers, refer to the Cisco MICA Modem Dial Modifiers for Cisco AS5300, Cisco AS5400, and AS5800 Universal Access Servers document.
Existing Features for Version 22.214.171.124
The following features continue to be supported with Cisco IOS Release 12.1(5)T.
Call Tracker expands the call handling and real-time monitoring capabilities of the Cisco AS5x00 universal access servers.
Internet Protocol Device Control (IPDC) Protocol—(CSCdp33808)
This release supports the IPDC protocol for call control signaling. 1000 Hz and 1004 Hz Configure Continuity Testing (COT) tones can be generated at 0 dbm0
New V.110 rates have been added for the ratified Q.931 recommendation: 38400, 28800, 24000, and 12000 bps. The following V.110 user rates (ISDN Q.931 bearer cap) are now supported: 600, 1200, 2400, 4800, 7200, 9600, 12,000, 14,400, 19,200, 24,000, 28,800, and 38,400 bps.
Decoupled V.90 Power Levels—S39/S59 (CSCdm52396)
You can set the transmit level for V.34 (using S39) separately from the transmit level for V.90 (using S59). The default for S59 is 6 (-12dBm). The default for S39 is 7 (-13dBm). The S-register values for S39 (V.34 transmit levels) and S59 (V.90 transmit levels) have not changed.
The following S-register caveats apply to decoupling the V.34 and V.90 power levels:
•Cisco MICA Version 126.96.36.199 allows setting the V.34 transmit power level (via S39) independently from the V.90 transmit power level (via S59).
•The V.34 and V.90 transmit power levels cannot be set hotter than -6dBm.
•The default for V.34 transmit power is S39=7 (-13dBm) for all countries except Japan (-15dBm).
•When the country code for Japan is entered (modem country mica japan), the actual transmit level will always be -15dBm.
•When the USA country code is entered (modem country mica usa), the default V.34 transmit power level is -13dBm (S39=7) and the default V.90 transmit power level is -12dBm (S59=6). Due to FCC restrictions, if a value lower than 6 (-12dBm) for S39 or S59 is selected, the modem reports OK but does not act on the command.
S54 General Capabilities Register—(CSCdp40871)
New values have been added for the S54 general capability register (default S54=136). The values shown below enable power control (CSCdk11008) and allow a 0.5 increment for the SQ value.
The bit field values in S54 are as follows.
Signal Quality (SQ) Threshold Changes
Bit 7 in S54 corresponds to a 0.5 increment to the signal quality threshold beginning with
Cisco MICA Version 188.8.131.52. This bit is set by default (see the description of S54 above).
This bit value works in conjunction with S32 to set the effective SQ threshold and to determine Cisco MICA receive speed. S32 is set to 2 and S54 bit 7 is set so that the effective SQ threshold is 2.5. The table below illustrates the relationship between the S-register settings, the effective SQ threshold, the trigger Bit Error Rate (BER), and the receive speed for a given signal-noise ratio (SNR)/bandwidth.
Note The receive speeds are for illustration only.
Improved Parity Support
Prior to the integration of CSCdj92333, Cisco MICA supported parity over async (non-error-controlled or EC) connections only. Cisco MICA Version 184.108.40.206 supports parity over EC as well as async connections. To use this feature, set bit 6 in S54, set S12 to 7, and set S13 to the desired parity setting from the following list:
• 0 for 7N1
• 1 for 7E1
• 2 for 7O1
For example, to enable 7 databits and even parity for EC and async connections, given the default value of S54 (136), use the &F&D2S12=7S13=1S54=200 modemcap where the following is true.
Client Modems for V.90 Digital Impairment Learning (DIL) Detection
Additional client modems have been added for DIL detection. For V.90 connections, DIL index values can be seen by entering the show modem operational-status x/y command in the Parameter #16 Tx Preemphasis Index:as2# show modem operational-status 1/7[ ... ]Parameter #8 Connected Standard: V.90Parameter #9 TX,RX Bit Rate: 45333, 28800Parameter #16 TX,RX Preemphasis Index: 21, 1
In this case, the Tx Preemphasis Index value of 21 signifies that this client is a Conexant ACF. The following table shows additional values displayed in Parameter #16 when the show modem operational-status x/y command is used.
Cisco MICA Portware Version 220.127.116.11 is supported on the following platforms:
Refer to the Cisco AS5x00 and Cisco 3600 Cisco MICA 6-Port and 12-Port Modem Module Portware/Cisco IOS Software Compatibility Matrixes.

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. The spe command is available for use with Cisco IOS Software Release12.0(4)XI1, 12.0(5)T, and higher.
The copy xxxx modem command on the Cisco AS5300 will no longer be available for
Cisco MICA portware and Cisco 56K Microcom modem firmware download beginning with
Cisco IOS Software Release 12.0(4)XI1 and higher. The existing modem portware and firmware configurations in the router will be converted to the SPE format so that functionality is not lost.
For 56K systems running Cisco IOS Software Release 12.0(4)XI1, 12.0(5)T, 12.1(2)XD, or higher, use the spe command to download firmware.
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(2)XD, 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.220.127.116.11.bin.Router(config)# spe 1/0 1/9Router(config-spe)# firmware location flash:mica-modem-portware.18.104.22.168.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:
