ABSTRACT:
Signaling is inserted (102) into a communication channel of a communication system by inserting the signaling into the communication channel if the communication channel has sufficient available bandwidth (104). If the communication channel does not have sufficient available bandwidth, reducing the bandwidth of information being communicated on the communication channel (106) and inserting the signaling into the communication channel (108) with reduced information bandwidth.
