- Annual death rate
- The total annual death rate, if possible projected a few years into the future
- Percent handled by Medical Examiners
- Percent of death records with medical data entered into the EDRS database directly by a physician. Typically these are most of the coroners and perhaps a few hospice physicians.
- Ratio of busiest day to average day
- Describes how busy days compare to average days. For example, if the death registrations on Tuesdays in January are 50% higher volume than average, enter 1.5 here.
- Pages sent or received
- How many pages are faxed to the physician when the working copy (or the attestation copy) is sent? And how many pages will the physician send back?
- Percent that will need reprocessing
- An estimate of the percentage of faxes that will need to be re-sent due to inadequate information, errors keying the information and doctor's office fax machine errors.
- Peak day pages
- The number of pages sent faxed on a peak, or busiest, day.
- Peak day hours
- The number of hours a fax line will be in use on a peak, or busiest, day.
- Average minutes/month
- The average number of minutes of phone time needed per month, useful for telecoms cost estimation
- Disk space (GB/yr)
- The space used per year to store images, useful for configuring server disk size
- Recall factor
- % of blocked calls that immediately redial one more time.
This calculator does not iterate the recall factor, i.e. does not assume people will redial multiple times.
Set this to zero to get the original Erlang B calculation
- Busy Hour Traffic (in Erlangs) is the total number of hours of phone time required during the busiest hour of the day, estimated as the peak day's traffic divided by 8 work hours per day
- Number of lines
- Number of lines available for use in one direction (incoming or outgoing faxes)
