ABSTRACT:
An inter-channel bank addressing and identification protocol, for use with a multi channel bank, digital subscriber line access multiplexer (DSLAM), enables the control processor of a master channel bank to selectively communicate with control processors of subtended slave channel banks, and allows a subtended slave shelf to retain provisioning information, irrespective of a change in shelf location or removal of a subtended slave shelf between the master shelf and another subtended slave shelf. The inter-channel bank addressing and identification protocol uses a shelf address code that is controllably incremented or decremented during the transport of a packet between the master and a slave shelf. In addition, a shelf address code is assigned each slave shelf during initialization. These two codes enable the master to track which channel bank is in which shelf bay.
