- 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.

This section notes known issues with Portware 188.8.131.52; 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 issuesUnder 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 dropsUnder certain conditions calls drop. The length of the connection varies.
- CSCdj45528, CSCdj61813, CSCdj60846 and CSCdj62696- Connectivity issuesWith 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 pingsUnder 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 failWhen 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 valueThe at\s command shows incorrect value.
