These release notes document Cisco MICA portware, version 2.6.1.0, which supports SS7 (Signaling System 7) Continuity Testing (COT). This portware functionality is used in the SS7 networks to provide status on DSO channels and to detect failures on the channels by generating and detecting the COT tones.
This document includes the following sections:
Cisco MICA portware, version 2.6.1.0 software is designed for MICA modules.
The modules require the following images:
V.90 and Data Dial out compatability matrixes for Cisco AS5200, Cisco AS5300, and Cisco AS5800 can be found at the following URLs:

The following V.90 modems have been tested and can successfully establish V.90 connections with this release of Cisco MICA Portware, version 2.6.1.0:
V.90 client modems using Lucent chipsets need an additional command in order to connect to an access server in V.90 mode. The following paragraphs describe how to use the additional command to connect the modems using these chipsets to an access server.
V.90 client modems using Lucent chipsets connect in K56flex mode by default on any access server. To connect a client modem with a Lucent chipset in V.90 mode, enter the following command:
ats109=2
If the modem responds with ERROR, the modem you are using does not contain the Lucent chipset. You may also check your modem for Lucent chipsets with this command:
ati11
A modem using a Lucent chipset will respond with output similar to the following:
ati11 Description Status --------------- ------------ Last Connection NA Initial Transmit Carrier Rate NA Initial Receive Carrier Rate NA Final Transmit Carrier Rate NA Final Receive Carrier Rate NA Protocol Negotiation Result NA Data Compression Result NA Estimated Noise Level NA Receive Signal Power Level (-dBm) NA Transmit Signal Power Level (-dBm) NA Round Trip Delay (msec) NA Near Echo Level (-dBm) NA Far Echo Level (-dBm) NA Transmit Frame Count 0 Transmit Frame Error Count 0 Receive Frame Count 0 Receive Frame Error Count 0 Retrain by Local Modem 0 Call Termination Cause 0 Robbed-Bit Signaling NA Digital Loss (dB) NA OK
