Developers of infrastructure equipment. Were working with C62 & C64. Information in this presentation will be relevant for designers of large-medium systems (hundreds of ports). First problem designers will need to face is bottle necks of HW & SW design. Next problem will be mass deployment, how to manage & support this deployment. Answer customer requirements for low risk, time-To-Market
We will use the 2 terms of HW & SW framework HW with multiple DSPs needs aggregation of traffic SW FW is the SW in the DSP – Voice/Video processing algorithms
ECAN - Echo canceller
If now you support voice and in the future you will want to add video you must make sure it is possible to add this in the future. It must be open to add new media types. C64 is the only open system because it has external memory. We have 0 overhead from density perspective when providing this capability
You need to make sure that your support engineers can connect from the lab to the field system and extract data for any channel and any media type. The diagnostics must be part of the release version. If it is only in the debug release you will not be able to get the data when problem happens. Some vendors don’t provide this due to memory constrains. Security – Make sure not every one can connect to the system
