Hello. I am having a problem with the Total Control 1000 and using it as a dialout modem server and could use some help or suggestions. I am using the Total Control 1000 with the 96port modem cards. Right now I have 4 T1's plugged into it for testing, but will soon switch to the DS3 ingress card. I have setup modem pools in a round-robin configuration and a network service for dialout. I am then using Dialout/IP by Tactical Software to connect to the 3Com Total Control and dialout. The issue I have is that roughly 20% of the time I get a modem error from the software, saying that a modem is unavialable and/or communication error with the modem. I have tried everything I can on the PC side, such as different modem INF files, compression settings, checking the DialOut/IP software, etc.. Everything seems fine on that side. 3Com is telling me that everything is configured correctly on the Total Control. Yet just today I witnessed the HiperArc reboot on its own. The firmware and system software versions are: Router Card hardware ver 20.0.0 Software Ver 5.1.99 DSP Multi Span Nac Hardware ver 0.2.0 Software Ver 3.0.14 Does anyone have any suggestions what else to try or do? As a side note, I have a number of the quad racks setup for this with no problem. Although its not using the HiperArc instead its using the physical serial connections. Its just on the newer Total Control 1000 that I have problems...
