Release Note для Nortel 4000

300221-C Rev.00

3-1

This chapter outlines problems that have been fixed from prior 
versions of the router software.

The following are corrections that have been made to the router 
software:

•

Corrections to the Call Waiting feature now allow full 
operation in areas where this facility is supported.

•

It is now possible to download firmware to BRI-ST and 
BRI-U ISDN TA modules in a Nautica 4000 using the 
Nautica Wizard NDEVLOAD utility.

•

If a retry is required for a ‘bandwidth’ ISDN call (additional 
data channel), the router code now correctly marks this as a 
demand call. Previously, retried calls were always marked as 
automatic calls, which could prevent the correct operation of 
incoming and outgoing call bumping.

•

Incoming voice calls now reliably bump data calls. In the 
previous release, the data channel was occasionally not fully 
disconnected, resulting in spurious noise at one or both ends 
of the voice call.
