Release Notes for Cisco Portware Version


These release notes document Cisco Portware Version, which supports the MICA 6-port modem module carrier card for the Cisco universal access server.

This document includes the following sections:


To support the 6-port modem carrier card, the Cisco AS5300 requires Cisco IOS Release 11.2(9)XA or later, which contains the following features:

  • R2 E1-based signaling

  • DNIS detection with CAS

  • Modem pooling based on DNIS numbers in CAS

The 6-port MICA modem carrier card requires the following images:

  • Cisco IOS image

  • Boot Cisco IOS image

  • Portware (bundled in Cisco IOS software)

Because Boardware and Portware are bundled in Cisco IOS software, these two modem code images are loaded automatically.

Cisco IOS Software Caveats

None at this time.

Outstanding Bugs

This section notes known issues with Portware; sources include Cisco Devtest and Development groups and customer feedback. Many of these issues are unlikely to occur, but need to be explained. Each issue is listed by its DDTs number where relevant, and is assigned a visibility weight that estimates the possibility of the issue being seen or used.

Note This section lists the known Severity 1, 2, and 3 DDT problem reports. For full details and to see all of the Portware DDTs reports, please refer to the CSC.dialtech project under the CSC.access class in the DDTs database.

Following are the known problems:

  • CSCdj44302 and CSCdj13463 - Receive issues—Under certain conditions connect speed varies from 26400 bps. The receive connect rates vary and do not reliably connect at the highest rate even over clean lines.

  • CSCdj45522, CSCdj60850 and CSCdj54904 - Call drops—Under certain conditions calls drop. The length of the connection varies.

  • CSCdj45528, CSCdj61813, CSCdj60846 and CSCdj62696- Connectivity issues—With specific versions of modems: the Psion Gold PCMCIA 33.6, Option International 40 PCMCIA, Multitech 28.8 PCMCIA and Apex.

  • CSCdj27603 - Consecutive retransmission disconnects (0x70) during sweep pings—Under some situations, the HMM will disconnect (reason 0x70). The test case is: a client dials into a router, establishes ppp, and then from the router issue sweep pings back to calling modem.

  • CSCdj38981 - Unable to connect in MNP 4/5 with some client modems when LAPM is disabledSince most modems use LAPM instead of MNP 4/5, this problem can be avoided in most cases by using LAPM.

  • CSCdj50614 - ARAP connections fail—When a USR X2 Sportster modem on a Macintosh computer is used for an ARA connection, the connection is unsuccessful.

  • CSCdj35143 - Ats command tx level reduction showing incorrect value—The at\s command shows incorrect value.
