Claim One:
1. In a simulcast communication system that includes a plurality of sites, at least two transceivers, and a plurality of communication units, wherein each site of the plurality of sites includes at least one receiver, and wherein the plurality of sites are operably linked together by a digital communication network, a method for a first transceiver of the at least two transceivers to determine simulcast delay times of the digital communication network, the method comprising the steps of: a) receiving an indication of a call assignment on the digital communication network to produce a call assignment indicator; b) upon receiving the call assignment indicator, forming and transporting, by the first transceiver, a first time stamp message on to the digital communication network; c) receiving, from at least a second of the at least two transceivers, at least a second time stamp message; d) calculating, by the first transceiver, an inbound delay time for the at least second of the at least two transceivers, wherein the inbound delay time is based on the at least second time stamp message and a time when the at least second time stamp message was received; e) storing the inbound delay time for the at least second of the at least two transceivers to produce stored inbound delay times; f) calculating inbound delay time threshold based on the stored inbound delay times; g) transporting the inbound delay time threshold to the at least second of the at least two transceivers; and h) storing the inbound delay time threshold.
