A maximum of four single-carrier cabinets can be stacked on top of each other to 
form a single Processor Port Network or Expansion Port Network. There are four 
types of single-carrier cabinets:
Control cabinet (located in the Processor Port Network only), which 
contains ports, a control complex (for call processing), and an optional 
interface to a duplicated control cabinet.
Duplicated control cabinet (optional and located only in the Processor Port 
Network), which contains a duplicated control complex, ports, and an 
interface to an expansion control cabinet.
Expansion control cabinet (optional and located only in an Expansion Port 
Network), which contains ports, a tone-clock, an interface to a Processor 
Port Network cabinet, and a maintenance interface.
Port cabinet (located in the Processor Port Network and in Expansion Port 
Networks), which contains ports and an interface to an expansion control 
cabinet.
