Message-ID: <851025032350.613033@MIT-MULTICS.ARPA> Date: Thu, 24-Oct-85 23:23:00 EDT Article-I.D.: MIT-MULT.851025032350.613033 Posted: Thu Oct 24 23:23:00 1985 Date-Received: Sat, 26-Oct-85 08:33:32 EDT Sender: usenet@ucbvax.BERKELEY.EDU Organization: The ARPA Internet Lines: 7 Approved: telecom@ucbvax.berkeley.edu As I've noted in a previous note, the AML has a serious side effect of reducing the voltage on the second line to 16 volts thereby causing equipment that depends on voltage to fail. In particular hold buttons that attempt to detect another phone off hook by detecting the voltage change. I had my AML removed and replaced by separate pairs.
