These release notes describe Cisco MICA Portware Version 2.7.2.0 with Cisco IOS software on Cisco AS5x00 universal access servers and Cisco 3600 series routers.
The features supported in Cisco MICA Portware Version 2.7.2.0 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:
The following features are new in this release.
Call Tracker
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
V.110 Speeds—(CSCdm43898)
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.
Dial Modifiers—(CSCdk10292)
 |
Note Cisco IOS software support for dial modifiers will be supported in a future release. |
Dial modifiers X, W, and (,) are supported where the following is true.
| Dial Modifier | Definition |
X | Switch to in-band DTMF mode for any subsequent digits remaining in the ATD string. The X dial modifier has been added to serve as a delimiter for the host when processing the dial string. Allows Cisco MICA portware to be used in many environments that do not support DTMF dialing (for example, PRI). |
W | Wait for dialtone then switch to in-band DTMF mode for any subsequent digits remaining in the ATD string. The W dial modifier also acts as a delimiter between the primary and secondary sections of the dial string, so no additional X modifier is needed. Once either an X or a W has been parsed in the dial string, any additional X modifiers are ignored. Additional W modifiers cause Cisco MICA to wait for a dialtone. |
, | Delay: Number of seconds in S8. Default is 2 seconds. |
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:

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:
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 2.7.2.0. 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.
S-Register Settings | Effective SQ Threshold | BER Threshold | Receive Rate 3200Hz/33dB | Receive Rate 3429Hz/37dB |

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 2.7.2.0 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:
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.90 Parameter #9 TX,RX Bit Rate: 45333, 28800 Parameter #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. Table 2 shows additional values displayed in Parameter #16 when the show modem operational-status x/y command is used.

For information about Cisco IOS software bugs and features for Cisco IOS release 12.1T, refer to the Release Notes for Cisco AS5300 Universal Access Servers for Cisco IOS Release 12.1 T and the Caveats for Cisco IOS Release 12.1 T.
If you have an account on Cisco Connection Online (CCO), you can use Bug Navigator II to find caveats of any severity for any release.
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. |
To download modem portware/firmware using the spe command, enter the spe command, 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.2.7.2.0.bin.
Router(config)# spe 1/0 1/9 Router(config-spe)# firmware location flash:mica-modem-portware.2.7.2.0.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. |
