New Features for Version 2.7.3.0

The following features are new in this Version 2.7.3.0 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.


S-Register
Default
Configuration Description

S64

-

Finer granularity in modulation selection.

0—Automode enable (Default - Proceed as defined in S29)

1—V.90

2—K56Flex

3—V.34

4—V.32bis

5—V.32

6—V.22bis

7—V.22

8—V.21

9—V.23

10—Bell212A

11—Bell103

Note S64 forces Cisco MICA to try the standard specified in S64 only. A fallback to V.34 is allowed if S64 is set to 1 (V.90) due to the V.8 specification.
If client modem is set to V.90 automode, and Cisco MICA is set to S64=5 (V.32), both modems will connect in V.32. However, if the client modem is set to V.21 and Cisco MICA is set to S64=7 (V.22), the connection will be dropped since Cisco MICA will not try any modulation other than V.22 in this case.

S71

5

V.90 Uplink Maximum Symbol Rate:

3:3000 baud

4:3200 baud

5:3429 baud

S72

3

V.90 Uplink Minimum Symbol Rate:

3:3000 baud

4:3200 baud

5:3429 baud


Continued Feature Support for Cisco MICA Portware

Cisco MICA Portware Version 2.7.3.0 continues to support Version 2.7.2.0 features. Refer to the
Release Notes for Cisco MICA Portware Version 2.7.2.0 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 2.7.3.0 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.

Value
Definition

0

All general options disabled

1

Reserved for engineering use

2

Enable aggressive client capping

41

Force 4-point training

82

Enable power control

16

Enable EC quality checking

32

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

642

Enable Universal Asynchronous Receiver/Transmitter (UART) functionality (CSCdj92333)

1282

Enable 0.5 increment for signal quality (SQ) value through S32 (CSCdr39887)

256

Digital signal processor (DSP) reset enable (CSCdp94025)

512

Enable V.110 blind connect (also called s&x) option to be the same as Cisco AS5200 (CSCdr39887)

1024

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.


Compatibility Requirements

Cisco MICA Portware Version 2.7.3.0 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 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.2.7.3.0.bin.

Router(config)# spe 1/0 1/9
Router(config-spe)# firmware location flash:mica-modem-portware.2.7.3.0.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.


For detailed information on the spe command, go to the following link:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120t/120t7/spe1206t.htm


Modem-Pool Download Tasks

If you have an account on Cisco.com, you can download modem portware/firmware using FTP if you are using Cisco IOS Software Release 12.0(5)T or earlier at the following link:
