A method and apparatus is disclosed for incorporating secondary data for transmission as part of or concurrently with network data. In one embodiment, the secondary data comprises communication system data for use in controlling or monitoring a communication system. In one example embodiment, the secondary data is utilized to control the transmit timing of the network data to thereby jitter modulate the secondary data into the transmission of the network data. By monitoring the timing variation, or jitter, of the received network data signal, the secondary data may be recovered. In one embodiment, the secondary data is encoded to reduce the amount of time variation, i.e., jitter, that occurs when transmitting the network data. Decoding may occur upon reception of the time adjusted network data signal. In one embodiment, the encoding comprises CDMA type encoding utilizing one or more orthogonal codes.
