The wiki calls the system Passport but Trident Micro Systems calls its system PassPort, which is a copyrighted trademark. It's a small difference but why not get it right?
There is no such thing as 'LTR Passport'. There are combined LTR and PassPort systems that share some or all of the voice channels. Dedicated separate LTR and PassPort home channels are required for the combined systems. The wiki says PassPort systems have at least three channels but a system near me has only two channels.
