There are two 9.5" chassis, the Base and Expansion . The base unit has three
universal slots, one expansion slot and one MPS7101 (power supply unit). The
expansion unit has three universal slots, no expansion slot, and no power supply
unit. When the GCD-CP10 is installed in the first slot of the base chassis, it is
called the Controlling Chassis. Additional chassis, called Expansion Chassis, can
be installed to increase the capacity of the system to meet the customer's
business needs.
The system can be expanded from 64 ports to 896 ports by vertically stacking a
maximum of three additional chassis onto the controlling chassis. This provides a
maximum of 24 slots and 368 digital terminals. To obtain the maximum port
capacity of 896 ports, three systems can be linked together via an IP connection.
Up to four combined CHS2UG B/CHS2UG E (3-Slot Base/3-Slot Expansion) or
CHS2UG (6-Slot) chassis can be connected locally to reach the system's
maximum port capacity.
