Important customer information about:
The Lucent Remote Access ComOS(R) 3.8.2c2 interim software release for the PortMaster(R) 3 Integrated Access Server is now available.
This release is provided at no charge to all Lucent customers.
This release note documents updates to the modem code. All other features are identical to those in ComOS 3.8.2.
NOTE: This interim software release is recommended only for customers who are experiencing the problems described and are unable to wait for the next maintenance release.
Before upgrading, thoroughly read "Upgrade Instructions."
* A NO EC (no error control) connection problem with Cirrus Logic modems is fixed.
* Performance with Cirrus Logic modems is improved.
* The number of rate renegotiations with USR/3Com and Cirrus modems has been reduced because ComOS now allows the client to specify spectral shaping.
* Rate renegotiation and retrain problems with USR/3Com and Rockwell HCF clients are fixed.
* Connectability with USR/3Com and Rockwell HCF modems and LT Winmodems is improved.
* A downward spiraling upstream rate caused by an incorrect Link Access Procedure for Modems (LAPM) error check is fixed.
* The number of disconnects from LAPM retrains within a retrain is reduced.
* Rate reduction due to LAPM errors has been made less sensitive.
* Motorola SM56 modems can now connect with V.90.
* A V.90-to-V.34 fallback problem, which can result in a disconnect, is fixed by earlier V.34 detection.
* A-law V.90 connectability is improved.
* K56flex connectability is improved by an increase in a K56flex timeout.
This ComOS release adds extended debugging information for troubleshooting.
Lucent Remote Access is still fixing some problems with Rockwell HCF and Cirrus Logic modems. If you experience any difficulties with modems, verify that the client modem is running the latest firmware, and then refer to http://www.livingston.com/tech/bulletin/comos-modem.html. If these instructions do not help, contact Lucent Remote Access Technical Support.
