In order to minimize the consequences of a hung port, it has Uniform Call Distribution (aka circular hunt). This is very important, as the system runs unattended most of the time. Thus there's no one there to reset a port that doesn't answer. For various reasons, I occasionally want to make either all or some of the lines busy. Right now, each for each line there is make busy switch provided by the telco (C&P of Maryland). Each switch has a circuit of its own going back to the central office, which is fairly expensive. What I would like to know is if there is a device I can get that will provide the same make busy capability without the circuit to the central office? If there is a call in progress, I want it to be allowed to complete. I would prefer to buy something rather than build, but it can't be too expensive or I won't save money. I'm also interested in alternatives to Centrex that could do this job, including the circular hunt as well as the make busy. I am aware that a modem using the Hayes command set can be told to take a line off hook, but this does not work in there is no modem connected. It also requires cooperation of the BBS software if a call is in progress -- the software must take the line off hook at the end of the call. In my configuration, that is possible, but not very convenient. Roger Fajman RAF@NIHCU (BITNET) RAF@CU.NIH.GOV (Internet)
