Hello, I'm a Linux user looking at migrating my ISDN router over to BSD after finally having enough with the problems with ISDN4Linux (hard lockups, MPPP issues, the fact it doesn't work with Linux 2.6 among others) and there is one question I can't seem to find an answer to: If I have a 128Kbps Synchronous PPP ISDN connection, is it possible to manually dial and hangup the "slave" channel to switch between a 64 and a 128Kbps link. The reason being is that during the day (this is a home ISDN connection) I need the second channel open to receive phone calls. At night, I can bring up both channels and run the connection at 128Kbps. I have a cron job at the moment that dials the slave channel at 10pm and brings it down at 7am. Under Linux (ISDN4Linux) this is performed by issuing the command "isdnctrl dial ippp1" (dial second channel) and "isdnctrl hangup ippp1" respectively. This function is critical if I'm going to switch over to BSD for Linux. I'm in Australia too. ISDN (DoV) is untimed but there is a per-call charge (18 cents) so I want basically to run 64K all the time, bursting to 128K at night. Thanks for your time, and yes, I'm a newbie. Brett.
