1 Although the system software will allow certain programs to be increased above the capacities shown here, the system's
capacities are limited due to the hardware (e.g. up to 72 trunks are available in Program 0901, but only 16 trunks are allowed
by the hardware).
2
Count toward total number of allowed hardware ports (28, 124, 384, or 704 - depending on the system).
3
These devices share the same pool of extension numbers. Extension numbers cannot overlap.
4
The maximum number of items is determined by the load factor for the system.
Extension numbers can be three or four digits long. See Flexible System Numbering.
