These release notes describe Cisco MICA Portware Version 2.7.1.0 with IOS Releases 12.0(4)XI1, 12.0(5)T, or higher on Cisco AS5x00. Version 2.7.1.0 adds the V.110 ISDN rate specification feature.
V.110 is a digital link access protocol for Cisco access servers, which operates over an ISDN B channel. V.110 enables Cisco access servers to connect to ISDN terminal adapters requiring V.110 compatibility. Cisco MICA V.110 supports data rates up to 38,400bps.
This document contains the following sections:
Cisco MICA Portware Version 2.7.1.0 is a feature release introducing support for ITU-T Recommendation V.110. V.110 is a specification for rate adapting low speeds over ISDN (64k DS0s).

This section describes known problems with Portware Version 2.7.1.0 that are associated with the V.110 feature or were introduced in version 2.7.1.0. If a workaround is not provided, the problem requires further investigation or a solution is being developed.
If you are having difficulty with V.110 call services on the on the Cisco AS5200 or AS5300, set the following debugs to on:
If you have difficulty with V.110 on the Cisco AS5800, set the following debugs to on:
You will receive the following console output if the incoming call is good after turning on debug:

The following is an example of a MICA V.110 call with NO llc octets. The received Bearer cap has no LLC octets so the call will be handled as a normal modem call, which will fail since the calling client wants to do a V.110 synchronized exchange:

For information on configuring your Cisco AS5x00 for V.110 with Cisco IOS Release 12.0x, refer to the Cisco document, Basic V.110 for MICA Modems on Cisco AS5x00 Access Servers (see Related Documentation).
For fax DialOut instructions, see the following URL:

The copy xxxx modem command on Cisco AS5200 and Cisco AS5300 and the firmware option, modem-pool command on the Cisco AS5800, will no longer be available for Cisco MICA portware and 56K Microcom modem firmware download beginning with Cisco IOS Release 12.0(4)XI1 and higher. The existing modem firmware configurations in the router will be converted to the new spe format so that functionality is not lost.
For 56K systems running Cisco IOS Release 12.0(4)XI1, 12.0(5)T, or later, a new spe command is available for firmware download. A Service Processing Element (SPE) unit is defined as the smallest software downloadable unit, which is six or twelve MICA modems, depending on whether the modules are singe- or double-density.
To download modem portware/firmware using the spe command, do the following:
Step 1 Enter the spe command, one configuration command per line.
For the Cisco AS5200 and AS5300, use the following format:
router# conf t router(config)# spe <slot>/<spe_begin> <slot>/<spe_end> router(config-spe)# firmware location <the_filesystem:filename>
For example, the following display shows a Cisco AS5200 or 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.2.7.1.0.bin.
router(config)# spe 1/0 1/9 router(config-spe)# firmware location flash:mica-modem-portware.2.7.1.0.bin
For the Cisco AS5800, use the following format:
router# conf t router(config)# spe <shelf>/<slot>/<spe_begin><shelf>/<slot>/<spe_end> router(config-spe)# firmware location <the_filesystem:filename>
In this example, the following display shows a Cisco AS5800 SPE download to all modems in Slot 1 (that is, all modems on a feature card containing twelve 6-port modem modules). The modem code resides in the Flash memory, and the modem code filename is mica-modem-portware.2.7.1.0.bin.
router(config)# spe 1/1/0 1/1/11 router(config-spe)# firmware location slot0:mica-modem-portware.2.7.1.0.bin
Step 2 Enter CNTL Z to return to the router prompt:
router(config-spe)#CNTL Z router#
Step 3 Copy the configuration from the running RAM into the NVRAM:
router# copy running-config startup-config
Download occurs when the modems become available.
1. SPE range cannot span across the following:
(a) Empty slots.
(b) Empty SPE units.
(c) SPEs of different firmware attributes in adjacent slots.
2. SPE range must represent the same hardware.
3. New SPE inserted in place of old with higher SPE capacity will do the following:
(a) Break the SPE range if the original SPE is nondefault.
(b) Expand the range if original SPE is the default.
4. New SPE inserted in place of an old one with lower SPE capacity will shrink the SPE range.
For the latest information on known problems, follow these steps to create a bug Watcher Bin in the Software Bug Toolkit from Cisco Connection Online (CCO):
Step 1 Connect to CCO as directed in Cisco Connection Online.
Step 2 On the CCO home page, click LOGIN (which appears in green in the menu bar at the top of the page) and log in to CCO. If you are not a registered CCO user, follow the instructions to register so that you can log in. Login is complete when the word LOGIN no longer appears in green text in the menu bar.
Step 3 After you log in, click Software & Support on the CCO home page.
Step 4 Under the Technical Support menu, click Software Bug Toolkit II. (Software Bug Toolkit II is not visible on the Software & Support page unless you are logged into CCO as directed in Step 2.)
Step 5 Click Search for Bug by ID Number from the main menu or click Search by ID under Bug Toolkit in the left column of the screen.
Step 6 Enter a bug ID, such as CSCdj80580, in the Search for Bug by ID Number window and click SEARCH. The bug information is displayed.
Step 7 To watch activity on the selected bug, click the WATCH this bug button at the top of the screen. The Pick a Watcher Bin entry screen is displayed.
Step 8 Create a Watcher Bin for the bug selected by entering a New Bin Watcher name, such as V.90 Bugs. A new Watcher Bin is created. The new Watcher Bin creates a link to the Bug Watcher screen.
Step 9 Click Watcher to access the Bug Watcher screen. The new Watcher Bin link is displayed in the left column of the screen.
For instructions on using other bug tools, go to the bottom of the Toolkit II page and click Help---How to Use the Bug Toolkit or click Help under Common Tools in the left column of the screen.
