Note You can find the most current Cisco IOS documentation on Cisco Connection Online (CCO). These electronic documents may contain updates and modifications made after the hardcopy documents were printed. |
These release notes for the Cisco AS5300 universal access servers describe the enhancements provided in Cisco IOS Release 12.1(3a) XI1. These release notes are updated as needed.
For a list of the software caveats that apply to Cisco IOS Release 12.1(3a) XI1, see the "Caveats" section and Caveats for Cisco IOS Release 12.1 T that accompanies these release notes. The caveats document is updated for every maintenance release and is located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
Use these release notes with Cross-Platform Release Notes for Cisco IOS Release on CCO and the Documentation CD-ROM.
These release notes describe the following topics:
The Cisco AS5300 is a versatile data communications platform that performs two functions in a single modular chassis depending on the installed feature cards and IOS images:
The remote access server is intended for Internet service providers (ISPs), telecommunications carriers, and other service providers that offer managed Internet connections and medium to large sites that provide both digital and analog access to users on an enterprise network. By terminating both analog and digital calls on the same chassis simultaneously, the access server provides a clear, simple, and easy migration path from analog dial access services to digital dial access services.
The Cisco AS5300/Voice Gateway is a versatile data communications platform that provides the functions of an access server, router, and digital modem(s) in a single modular chassis. The Cisco AS5300 includes three feature card slots: one holds a T1/E1/PRI feature card, and the other two support modem feature cards or voice digital signal processor (DSP) feature cards. When equipped with modem cards, the Cisco AS5300 serves as a remote access concentrator for dial-up (modem or ISDN) Internet access. When equipped with voice feature cards and Voice IOS, the Cisco AS5300/Voice Gateway serves as a voice (VoIP) gateway. By using one slot for modems and the other for voice DSPs, the Cisco AS5300 can serve in both capacities. Modem, voice, or fax calls are routed to the appropriate cards/resources via Dialed Number Identification Service (DNIS).
For information on new features and Cisco IOS commands supported by Cisco IOS Release 12.1(3a)XI1, see the "New and Changed Information" section and the "Related Documentation" section.

To determine the version of Cisco IOS software running on your Cisco AS5300, log in to the Cisco AS5300 and enter the show version EXEC command:
router> show version Cisco Internetwork Operating System Software IOS (tm) 12.1 Software c5300-is-mz, Version 12.1(3a) XI1, RELEASE SOFTWARE
For general information about upgrading to a new software release, see Cisco IOS Upgrade Ordering Instructions located at:
http://www.cisco.com/warp/public/620/6.html
Microcode software images are bundled with the system software image—with the exception of the Channel Interface Processor (CIP) microcode (all system software images). Bundling eliminates the need to store separate microcode images. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards. Table 3 lists the current microcode versions for the Cisco AS5300.
You could have received a later version of modem code than the one bundled with the Cisco IOS software. The modem code in Flash memory is mapped to the modems. Unless you fully understand how Cisco IOS software uses modem code, it is important to keep the factory configuration.
The modem code release notes are on CCO and the Documentation CD-ROM:
On CCO at:
Technical Documents: Documentation Home Page: Access Servers and Access Routers: Firmware and Portware Information
On the Documentation CD-ROM at:
Cisco Product Documentation: Access Servers and Access Routers: Firmware and Portware Information
| Modem Module | Current Bundled Modem Code Version | Minimum Cisco IOS Release Required |
|---|---|---|
Microcom modems | Microcom Version 5.1.20 | 12.0(5)T and later |
MICA modems | MICA portware Version 2.7.1.0 | 12.0(5)T and later |
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
Cisco IOS Release 12.1(3a)XI1 supports the same feature sets as Cisco IOS Release 12.1(3), but Cisco IOS Release 12.1(3a)XI1 can include new features supported by the Cisco AS5300.
 |
Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com. |

The following sections list the new hardware and software features supported by the Cisco AS5300 for Cisco IOS Release 12.1(3a) XI1.
There are no new hardware features in the Cisco AS5300 for Cisco IOS Release 12.1(3a) XI1.
The following new software features are supported by the Cisco AS5300 for Cisco IOS Release 12.1(3a) XI1:
Prior to this release, store and forward fax has been supported only on MICA and Microcom modem cards. Voice applications, however, run on the C542 Digital Signal Processing Module (DSPM) and C549 DSPMs that populate a Cisco AS5300 voice feature card (VFC). Equipping a Cisco AS5300 with both store and forward fax and voice capabilities has been inefficient because of the need to use different technologies for each type of call.
Beginning with this release, the Cisco AS5300 VFC supports voice, fax relay, and fax store and forward on both the C542 and C549 DSPM. These applications can run on the same voice port, and you can dynamically switch from one application to another in the same call (IVR, voice, fax relay, and fax store and forward).
Also beginning with this release, the ITU-T T.38 standard for real-time fax relay is supported in addition to the Cisco proprietary implementation of fax relay.
The Interworking Signaling Enhancements for H.323 and SIP VoIP feature enables VoIP networks to properly signal the setup and tear-down of calls when interworking with PSTN networks. These enhancements ensure that in-band tones and announcements are generated when needed so that the voice path is cut-through at the appropriate point of call setup and that early alerting (ringing) does not occur. In also supports network-side ISDN and the reducing of speech clipping.
The VoIP Call Admission Control using RSVP feature synchronizes Resource Reservation Protocol (RSVP) procedures with H.323 Version 2 (Fast Connect) setup procedures to guarantee that the required Quality of Service (QoS) for VoIP calls is maintained across the IP network. Prior to Cisco IOS Release 12.1(3)XI, VoIP gateways used H.323 Version 1 (Slow Connect) procedures when initiating calls requiring bandwidth reservation. This feature, which is enabled by default, allows gateways to use H.323 Version 2 (Fast Connect) for all calls, including those requiring RSVP.
