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.
