7.4.2 KCS HW-Requirement Calculator
The KCS hardware requirement calculator is a Microsoft Excel sheet which determines the required hard
disk speed from fax and link throughput figures and configuration options.
The orange fields are input values. The white fields are calculated intermediate values, the result fields are
blue.
The message throughput of the KCS is split up into these 4 columns:
Inbound fax (fax line >> KCS)
Inbound link (KCS >> link >> link-specific mail system)
Outbound link (link-specific mail system >> link >> KCS)
Outbound fax (KCS >> fax line)
The 4 columns are independent, but linked by the logic of the message flow. For example the inbound fax
traffic and inbound link throughput are identical, if the inbound link or links work exclusively to route
received faxes into a link-specific mail system.
Inbound fax (fax line >> KCS)
The main input value of the inbound fax column is the number of fax lines. If the system has a group of fax
lines handling both inbound and outbound traffic (instead of dedicated inbound or outbound lines) one has
to estimate the ratio of inbound to outbound traffic and split the total number of lines accordingly. Check
also the reception log file configuration setting and the routing of inbound faxes via in-actions.
