I’ve installed an Acceleport RAS 8 card in a Sun PCI-based machine which is used as a dial-up access server for the non-profit ISP I’m involved with.
Up to now we’ve used standalone analog modem banks connected to Magma serial port cards.
We use the ‘mgetty+sendfax’ application available from:
to manage the dial-in ports. I’d like to use this with the RAS card but so far it’s resulted in partial success, but each modem on the RAS card gets locked in a busy state and the machine needs a reboot to get the RAS card ready to answer more calls.
‘mgetty’ works by ‘listening’ for ‘RING’ messages from modems, then enabling auto-answer, then waiting for the ‘CARRIER xxxx’ message. I’m assuming this method will still work with modems on the RAS card as they appear to behave just like regular modems in terms of how they communicate with host software applications.
The modem init string used for the standalone analog modem banks is ‘ATS0=0Q0&D3&C1’ which turns off auto-answer in anticipation of the ‘RING’ message once a remote modem calls the respective number to set up a data connection.
Will this init string cause problems for the RAS card modems? Should it be modified to ensure that the RAS card modems are not going to stay in a ‘busy’ state after a call is terminated?
That’s what appears to be happening. I’ve tried using ‘digiras_reset’ to reset modems seperately, and reset all modems, with no change in the busy state of the RAS card modems. If I test it out by calling one of the numbers, the ISDN NT1+ which provides the analog lines shows it’s ‘sync’ LED coming on to indicate traffic on the D channel, but after about 10 seconds the busy tone is heard so the RAS card is deciding that the relevant modem is busy.
One other possibility, and I’m sure this is a factor, is that the RAS card is not one of the parts marked as being suitable for Australia. It’s coming up with a list of Asian countries when I try and set the modem identity. The modem identity is presently set to ‘Singapore’. If this is likely to be a a cause of the problem I’ll have to find one of the RAS cards suitable for Australia…
Tips, advice, etc. would be gratefully received…
