Fixed - An error correction problem. When LAPM error correction is forced on the MT5600ZDX, it is not able to answer calls from USR modems. 30% fail to connect to USR Modems at 2400 baud V.22bis with MNP error correction.

This was fixed in firmware version 2.400B. The latest firmware can be downloaded from our Web site at:
