Unanswered Question

I want to know if the UC560-T1E1-K9 includes from factory enough DSP to handle the E1 and the 4 FXO ports?

I´m quoting this appliance to a customer who is migrating from a UC50 due to the user licenses capabilities.

Any help will be appreciated.

The UC560 comes with 8 DSP's capable of 16 g711 channels (128 total on the system) or 8 g729 channels each. Keep in mind the FXO and E1 ports are not the only features sharing the DSP resources, conferencing and codec translation use these as well.

Have a look at the platform reference guide below, it has quite a detailed breakdown of DSP resource utilization and scenarios:

Hi There,

Simply put the 560 will handle all of what you are asking for, plus much more... It us quite a powerful system with quite a fair bit of resources.

You have nothing to worry about
