On TD1232, Jacks 01 and 24 are programmed to ring immediately. All others are NoRing. The odd thing is, the jacks are ringing at alternate times: When CO lines (1 thru 4) ring, Jack 01 will ring once, then Jack 24 will ring, then Jack 01, etc. Is this a function of Jack 24 being on the TD170 expansion card? Is there anything to force Jacks 01 and 24 to ring simultaneously? Thanks
