Busy Hour Call Complete (BHCC) is a measure used to test IP Office systems under a high call load.
For BHCC tests, each incoming call rings for 5 seconds, is answered and stays connected for
6 seconds. The BHCC figures for the different IP Office control units are listed below. Note that
in some cases the BHCC figure achievable will be limited by the number of incoming trunks supported.
Preferred/Advanced Edition 32 locations, 1000 users total = 7200 BHCC
Server Edition 32 locations, 1000 users total = 14400 BHCC (Max)
“Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction and skillful execution; it represents the wise choice of many alternatives.”
this is all you find in the Matrix so you will not find a BHCA information.
The reason that the tender might ask for this is that it is rigged and the system they want to have has the information. I have seen that numerous times where the tender is written so that only one system can provide all the information and you could almost give them your system for free and they would still not hand you the contract.

Instructions to calculate BHCA
1 Multiply a subscriber's monthly minutes of usage by the percentage of traffic that occurs during working days. For instance, if a subscriber talks for 500 minutes in a month, and 80 percent of calls occur during the work week:
500 X 0.80 = 400
2 Multiply your answer by the percentage of voice traffic that occurs during the busy hour. For instance, if 10 percent happens during the busy hour:
400 X 0.10 = 40
3 Divide your answer by the number of working days per month. If each month contains 20 working days:
40 / 20 = 2
4 Divide your answer by 60.
2 / 60 = 0.0333.
This answer shows your phone traffic in Erlangs, a unit that represents hours of usage per subscriber per busy hour.
5 Multiply the answer by 3600.
0.0333 X 3600 = 120
6 Divide the answer by mean holding time, in seconds. If your mean holding time is 80 seconds:
“Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction and skillful execution; it represents the wise choice of many alternatives.”
What a ridiculous metric by which to choose a system, if they find this kind of cack important they will be one of those demanding customers that is never happy I reckon
Westi, I have found it too googling the web, even if I think the "step 4" is wrong because it should be devided by 24.
For all others, I agree too with your considerations, it's an useless and insignificant request, but I am quite sure you would try to answer if you would know we are talking about some hundred systems...
These values are theoretical and have no real value nowadays, looks like the tender is using a script written in the 50's when the bookmakers ruled on buying new office equipment, now it is the IT manager who decides and if I tell them the IP Office has a BHCA of 1.5 he/she will think "What a lunatic, is he really trying to sell me a phonesystem here?", give me a coffee and a smile and then it is "Farewell, we will call you." (NOT).
they probably spent 100000 Euros (or the equivalent 500000 Us Dollar ) to have a consulting company write the tender and the consulting company has no clue what they are doing but they love to BS with acronyms to confuse their customers and anybody not able to give them the right answer they dismiss as incompetent.
