ABSTRACT:
In a time division multiplex digital communication system, access devices are capable of generating and detecting data sequences that are normally suppressed by end user equipment for establishing in-band communications between the access device and selected intelligent channel units (ICU's ). An ICU initiates in-band communication with the access device by transmitting a service request sequence to the access device. The access device transmits a wake-up sequence to the ICU to establish in-band communication. Once established, in-band communications can then be used to accomplish automated provisioning, performance reporting, status reporting, alarm reporting as well as other important functions.
