Telecommunications system apparatuses and methods are disclosed. The apparatuses include a telecommunications system having a data transmitting and receiving apparatus, subscriber buses, and channel unit cards. First and second subscriber buses provide, respectively, a communication path to a first and a second data transmitting and receiving apparatus. A plurality of channel unit cards are coupled to the first and second subscriber buses. In one mode of operation, at least one channel unit card communicates data over the first subscriber bus. In another mode of operation, at least one channel unit card communicates data over the first subscriber bus and at least one other channel unit card communicates data over the second subscriber bus. A method of configuring a telecommunications system is also disclosed. The method includes selecting groups of channel unit cards and configuring each group to communicate data over a first and a second subscriber bus. The method also includes configuring a first data transmitting and receiving unit to communicate with the first group of channel unit cards over the first subscriber bus and configuring a second data transmitting and receiving unit to communicate with the second group of channel unit cards over the second subscriber bus.
