Trim Networks Naming Conventions
Introduction
Each trim network has been assigned a part number and descriptive title defining
the operational characteristics of that particular network. The alphanumeric
designation on the trim defines the network function. They are as follows:
•
•
frequency
•
insertion loss
•
whether it has a pad socket
•
which device it is intended to be used in
•
whether it will affect the forward or reverse path
Example:
LSP-2SDF
where:
LSP
LSP-2SDF
where:
LSP
= low single peak
2
= 2 dB insertion loss
S
= pad socket
D
= DA/SA
F
= forward
Abbreviation Name Structures
The diagram below shows the abbreviated structure that Cisco has developed for
selecting its trim network.
