2.3.3 System Capacity
Calls cannot be made or received when all of the DSP resources are being used.
The number of required resources must not exceed the DSP resources installed to the PBX.
For details about the DSP Resource Advisor, refer to "22.214.171.124 PBX Configuration—[1-5-1]
Configuration—DSP Resource—Setting—DSP Resource Advisor" in the PC Programming Manual.
For information about installing DSP cards, refer to "4.3.3 DSP S Card (KX-NS0110), DSP M Card
(KX-NS0111), DSP L Card (KX-NS0112)".
The number of available DSP resources is not restricted by any activation keys.
DSP Resource Reservation
DSP resources can be reserved for certain operations to avoid lack of resources for particular operations.
When the PBXs are connected in a One-look network, you can specify how many resources to allocate to each
The following examples show cases of allocating and reserving DSP resources.
For details about reserving DSP resources, refer to "126.96.36.199 DSP Resource Reservation" and "188.8.131.52 DSP
Resource Advisor" in the Feature Guide, and "184.108.40.206 PBX Configuration—[1-5-1] Configuration—DSP
Resource—Setting—DSP Resource Advisor" in the PC Programming Manual.
In this example, the DSP M (127 DSP resources) is installed and resources are reserved for the following
VoIP (G.711) Calls
UM Tone (Fixed)
Because the system reserves 2 resources for internal system functions, the total amount of available resources indicated will be 2
less than the total resources of the installed card(s).
(40 x 1) + (10 x 0.5) + (8 x 1.3) + (10 x 2) + 2
= 127 - 77.4
This is an example for a stand-alone KX-NS1000 without any stacking PBXs.
