Chapter 2 — Transmission parameters

Standard 2.0
The loss plan strategy for PE 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
1,
2
and
3
provide loss values measured in decibels (dB) for
connections between:
•
PE ports (lines and trunks)
•
Digital ports (PRI or DTI)
Tables
1,
2
and
3
are in matrix format; note the direction of the arrows when
searching for a loss value.
