End-to-end connection loss is one of the most important aspects to consider
when planning private networks. That is because end-to-end connection loss
is a major element in controlling transmission performance parameters, such
as received volume, echo, noise, and crosstalk. In digital networks, loss
provisioning is a function of network switching. Therefore, in private
networks the loss plan of the PBX is fundamental to the overall network loss
design.
The insertion loss of a PBX connection is defined as the level difference
between the power delivered from a reference signal source connected across
an input port to a measuring instrument connected across an output port, with
• the path through the PBX connected
• the path through the PBX replaced by a direct connection
