Portions of transmitted messages, such as a portion of a service option field, can include a coded representation. The coded representation can correlate to previously stored information as retained at a receiving unit. Upon receiving the coded representation, the receiving unit can use it to access a specific item of previously stored information and then use that information. For example, a previously stored text message can be displayed and/or special annunciation tones can be used to signify specific events, such as the initiation of an interconnect or dispatch call type prior to actual complete initiation of such a call. In one embodiment, a relative station of transmission as corresponds to the coded representation can also be used to further aid in correlating the coded representation to a specific item of information.
