Small system transmission parameters
The insertion losses between various Intelligent Peripheral Equipment (IPE)
ports are connection-specific in order to be compatible with end-to-end
network connection loss requirements. The small system loss specifications
are in agreement with North American standards, which are formulated to
provide satisfactory end-to-end performance for connections within private
networks and between private and public networks.
The loss plan strategy for IPE combines electrical loss with terminal acoustic
parameters for optimum transmission performance. For this reason, some
connections have asymmetrical loss in order to conform with network loss
plans. This asymmetry is resolved at a remote point (another switch) in the
overall connection.
Tables 83, 84, and 85 provide loss values measured in decibels (dB) for
connections between:
• IPE ports (lines and trunks)
• Digital ports (PRI or DTI)
Tables 83, 84, and 85 are in matrix format. Be aware of the direction of
the arrows when searching for a loss value.
