Hi Anand,

For BHCA, as per the design guide

BE6000M and BE600H support a maximum of 5,000 BHCA. With BE6000, adding nodes or hardware platforms is supported to provide high availability, but that does not increase capacity.

With Cisco Business Edition 7000, the normal capacity planning rules of Unified CM apply. For example, user and endpoint capacity increases when nodes are added.

BHCC details can be checked here

Hi Manish,

Thanks for your response.

I want to know BHCC. The link you shared i already have; its showing cluster wise; the thing i want to know for System only not for the system.

BHCC = BHCA * ASR
Where, ASR = Attempt Seizure Ratio or Answer Seizure Ratio

ASR refers to probability of a call to get free traffic channel and call to be completed. It is usually measured after the complete operations. It is typically taken between 0.65 to 0.8.

so could you please let me know for the system or separately for all versions of BE6K and BE7K.

Regards,

Anand
