In a communication controller having clustering/multiplexing capability for other communication controllers, the customer must be able to perform the problem determination and the failure isolation from the machine provided with the clustering/multiplexing capability and must not take actions from the other machines. This article describes a method to perform these functions in this environment. The time division multiplex (TDM) functions are packaged in the base communication controller (CC) box, and a group of other communication controller boxes may use the bandwidth of the high speed line. The communication controller in which is packaged the TDM functions can use two lines at 256 kilobits per second and up to four controllers can be connected to the first one using one line at 256 kilobits per second (as an example).
