Have 2 different simulcast systems running on these microwaves 1 is a TAIT system that is IP connected and an older system that uses Gates-Air Muxes. The older system only passes packets thru ip link but no verification of resending missed packets causing hiccups in the system. I have the Link mode optimization set to IP currently if i change to TDM Traffic will this correct the hiccups but cause a problem on other system
