2 Practical Engineering Parameters
In order to ensure the optimal performance of a teleCARE IP system it is important to consider certain
parameters and limitations. The following tables show the most important practical values which can
have an influence on the teleCARE IP system performance.
WARNING: Any deviation from the values and recommendations shown in the following tables
can significantly reduce the performance of the teleCARE IP system.
2.1 General Limitations
2.2 Network Expectations
teleCARE IP Items
