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
Practical Limits
NIRC3s per NISM Max. 200

Network Expectations
The LAN installation must be certified and tested in accordance with
ANSI/TIA/EIA-568-A.
The LAN must be dedicated and isolated from any general purpose LAN
The LAN installation should be in accordance with ANSI/TIA/EIA-568-A
LAN cable type: Category 5 (or higher)
Maximum LAN cable length: 328 ft (100 meters)
The LAN must only use switching equipment listed in UL file E360946.
A switch port is required for each room controller
Existing customer LANs must be assessed by Ascom before committing
(not applicable for UL2560 installations which prohibit use of customer LAN's)
