Can someone explain how residential Centrex (which I believe is offered by Illinois Bell) works (ie. connections to the CO, what premises equipment is required, etc). Thanks, Lou Judice Digital Equipment Corp. Piscataway, NJ 08855 201-562-4103 [Moderator's Note: Nothing is required except the requisite number of pairs from the CO and the single line instruments. Everything else is in the software at the CO. PT]

Lou asked how residential Centrex works. Here is how mine is set up. We are served by a 5ESS CO, and US West calls the service "CentraFlex". When someone calls out number and it is busy, the call rotates over to our second line. When that number is busy, a third incoming call will give a call waiting tone on the second line. The call on the second line is put on hold (flash *9) and the second call is answered. Then that call can be transferred with another hookflash and any other number can be dialed. We also have call transfer...nice if I am in the basement and want to transfer the call back to the other line so someone on the 2nd floor can get it. We also have intercom from either line by dialing #2. Actually #2 is just the intercom code for the first line, but it works both ways since the first line dialing itself will roll to the 2nd line. Right now I am on the modem on the first line, wired thru a Proctor group exclusion module so no one can interrupt. Any incoming calls roll to the 2nd line. One thing the call transfer is fun for...saving my friends toll charges. Here in Seattle we have WIDE extended area service to the suburbs, but most of the burbs cannot call each other without paying toll. So my friends call me, tell me the number, I hookflash and dial it, then hang up....it ties up a trunk or two in my CO, but does not tie up my line. Tad Cook tad@ssc.UUCP
