Abstract
A base station (222) capable of receiving reverse channel data using two over the air protocols preferably comprises a transmitter (224) and modulator (226) for forward channel transmissions in at least a first protocol, a multi-mode base receiver (228) capable of receiving data on a reverse channel using multiple protocols including the first protocol and at least a second protocol. The dual mode base station further comprises a processor (242) that receives a timing source for the second over the air protocol derived from the remote controller (216) for the second over the air protocol. The processor is preferably programmed to decode timing information from the timing source allowing the multi-mode base receiver 228 to provide a busy indicator to the transmitter 224 and modulator 226 to inhibit the reverse channel of the first over the air protocol during a period set by the busy indicator.
