New Features for Version

The following feature is new in this release.

Dial Modifiers—(CSCdk10292)

Dial modifiers X, W, and (,) are now supported where the following is true.

Table 1 Dial Modifiers for Cisco MICA Modems

Dial Modifier


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).


Wait for dial tone 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 dial tone.


Delay: Number of seconds in S8. Default is 2 seconds.
The (,) dial modifier is treated as a silent DTMF tone for the duration of seconds specified in S8. The (,) is only acted upon after the call switching module (CSM) has been transitioned into DTMF mode which requires that it either follow an X or a W in the dial string or that the T1/E1 is configured for DTMF signaling.

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:


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

The following features continue to be supported with Cisco IOS Release 12.1(5)T.

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.

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.















-12dBm (default for S59 in Cisco MICA Portware Version and higher


-13dBm (default for S39 in Cisco MICA Portware Version and higher)

















The following S-register caveats apply to decoupling the V.34 and V.90 power levels:

Cisco MICA Version 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.



All general options disabled


Reserved for future release


Enable aggressive client capping


Force four-point training


Enable power control


Enable EC quality checking


Cap receive (Rx) rate to 26,400 when detecting PCTEL Modem (CSCdm45403)


Enable parity over EC (CSCdj92333)


Enable 0.5 increment for SQ value via S32 (CSCdp40871 - see below)


DSP reset enable (CSCdp94025)

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 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


Bit 7 in S54 is clear






Bit 7 in S54 is set






Bit 7 in S54 is clear





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 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.



Reset to factory defaults


Do not reset to factory defaults upon trainup failure


7 data bits


Even parity


Bit-mapped register


Enable power control (default)


Enable parity over EC


Enable 0.5 SQ value increment (default)

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. The following table shows additional values displayed in Parameter #16 when the show modem operational-status x/y command is used.

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 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.

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

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:
