I know I have made these comments to some in private mail, but I'll comment here since they seem to be coming up again and again. I have used the Ring Director (four line version) from Lynx Automation for several months without any problem. It's on a 5 ESS office with the Selective Ringing <tm> and it quickly switches upon a valid ring code and does not false. It does have an exclusion switch. If this is off, any device going off hook will 'step on' an existing connection. If this is on, a connection on any one line will lock out all others, except for what appears to be a volt or so of battery. One thing I thought of checking for but did not was to see how it operates on a PBX. I use it on a normal Selective Ringing line with the normal two on, four off cadence. On the PBX at work, (S/85) we have a 1 on, two off cadence with normal ringing for on-campus calls, two short for outside calls, and short- short-long for priority calls. I guess I should take it in and see what it does there. Hello Direct lists only the two-line box. I phoned Lynx directly and ordered the four-line one. As an aside, for a while, I was actually able to use two modems, a HST Dual and an older silver Hayes 1200 on two separate ring codes simply by connecting them in parallel to the jack. At the time, the HST counted the two short as two rings, and the Hayes counted it as one. I set the S0 register of the Hayes to three and the S0 of the HST to four. Normal ringing would cause the Hayes to pick up on three while the HST waited for the fourth. Two short would cause the HST to pick up on the second burst of two rings while the Hayes waited for the third. The only major problem was that if I was on the 1200 and the HST would grabe the line and attempt to dial out, it would generate all kinds of line trash. This 'feature' disappeared when the HST was upgraded to V.42, and it now responds like the Hayes, showing each burst of two short as one ring. Good Day! JSW
