Abstract: A unique byte is used to bookend commands and data for the purpose of allowing inband signalling and command communication between the IWF and the BSC portions of a mobile communication system having DS0 maximum data rate transfer capability per data channel. The receipt of two consecutive ones of the unique bytes indicates that the next 2 bytes will be a command. The receipt of 3 consecutive ones of the unique bytes indicates the next byte will be data. This inband signalling and data transfer allows the IWF functionality to be remote from the main switch used by a given BSC.

Abstract: A unique byte is used to bookend commands and data for the purpose of allowing inband signalling and command communication between the IWF and the BSC portions of a mobile communication system having DS0 maximum data rate transfer capability per data channel. The receipt of two consecutive ones of the unique bytes indicates that the next 2 bytes will be a command. The receipt of 3 consecutive ones of the unique bytes indicates the next byte will be data. This inband signalling and data transfer allows the IWF functionality to be remote from the main switch used by a given BSC. The CDMA system uses the inband signals to pass a plurality of data packets in parallel on DS0 capacity channel links through the MTX in a half-duplex burst whenever a data buffer within the IWF or a connected high data transfer rate mobile station is filled to a given level. This burst process may operate on a time multiplex basis with low speed data transfers using the same DS0 links to communicate with the IWF.
