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.
The 3 other input fields (“average message size in bytes”, “fax line usage per message in seconds” and
“average number of pages”) have preset values which should be about right for an average installation.
The “peak message throughput per hour” value is calculated from the “fax line usage per message in
seconds
” input value and the number of lines.
Inbound link (KCS >> link >> link-specific mail system)
The inbound link column has only one input field “peak message throughput per hour”. If for example all
inbound fax messages are routed to an inbound
link, the “peak message throughput per hour” figure of the
inbound fax column to the left can be copied in here. If all inbound fax messages are both printed by an IP
Printer and routed to a link take twice the message throughput value of the inbound fax column.
Outbound link (link-specific mail system >> link >> KCS)
The main input field of the outbound link column is the “peak message throughput per hour”. The
throughput of the outbound link may be set higher than the throughput of the outbound fax lines if the link is
expected to quickly put a number of messages into the KCS which are then sent out more slowly by the fax
lines.
The 2 other input fields (“average message size in bytes” and “average number of pages”) may be adapted
if required.
Outbound fax (KCS >> fax line)
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 sending log file configuration setting and the back-reception and delivery notification sending
options.
