I use the ASAP TF555 switch (roughly $120) to feed voice telephones, an answering machine, and two Unix nodes all off the single relatively expensive foreign exchange phone line I have between Scotts Valley and San Jose. My UUCP partners just have to add a few digits and commas after the phone number in their dialing scripts. It works great and saves me a fortune. The only caveat. When the DTMF gets faster than 60 ms., the ASAP starts dropping digits. To counter this with my speedy UUCP partners,I just make sure they add more digits = 555-1234,,888,888,888. At 70 ms., the switching would be reliable with simply 555-1234,,88,88, for example. -- KUFX | w ["] | WA6MBV 94.5 |... |___|_____..duncan@ravel.ati.com | Jim Duncan FM | H | ---------- ******** \_____I_____/ 37 3 10N/121 59 10W **************
