Hello all, I have only one customer that seems to be trying to MPP (not MP) and they always get the following error message: Failed to receive a NULL MP message He can get one channel up without a problem, but once he tries to bring the second channel online the lines (all of them) hang up. Here are my MPP settings in ANSWER-DEFAULTS [in ANSWER-DEFAULTS:mpp-answer] enabled = yes dynamic-algorithm = quadratic bandwidth-monitor-direction = transmit increment-channel-count = 1 decrement-channel-count = 1 seconds-history = 15 add-persistence = 5 sub-persistence = 10 target-utilization = 70 They are the default that the TAOS is set for. Any thoughts or ideas on what this problem could be. To the best of my knowledge none of my other customers use MPP, but pleanty use MP and have no problems. I know he is using a Diamond Shotgun modem and he is a user we acquired from an ISP purchase. They used Ascend 6000's and he had no problem with them. I have MaxTNT's with the new 96 port DSP modem cards. Thanks! -- David A.
