2.5.2 System Capacity
Three System Capacity charts are provided below. These include the General System
Maximum Capacities Table 2.5.2-1, the capacity based on the MBU type Table 2.5.2-2 to
Table 2.5.2-5. Note that the maximums are not simultaneously achievable. However, the
maximum number of VoIP channels is separate from other external network and station
maximums. That is, up to 16 VoIP channels are available in addition to CO, BRI and PRI
Lines. Also, the 48 DECT stations are separate from other station maximums.
