Path: utzoo!telecom-request Date: 24 May 91 02:22:42 GMT From: Ken Mandelberg Newsgroups: comp.dcom.telecom Subject: Modem Isolation Device Needed Message-ID: Organization: Emory University, Dept of Math and CS Sender: Telecom@eecs.nwu.edu Approved: Telecom@eecs.nwu.edu X-Submissions-To: telecom@eecs.nwu.edu X-Administrivia-To: telecom-request@eecs.nwu.edu X-Telecom-Digest: Volume 11, Issue 394, Message 2 of 10 Lines: 16 When my modem is connected to my phone line, I can hear a hum on extension phones. The hum appears on extensions not connected to the modem (as well as one that is connected through the modem). The hum doesn't effect the modem at all, as far as I can tell. Is there an isolating device I can put between the modem and phone line that would isolate the modem (and hum) when the modem is not off hook.
