Differences between Full and Limited Centrex 3
Full Centrex and limited Centrex differ in where and how PBX functions are
provided:

extensions.
■ In limited Centrex, the Centrex service provides PBX-like services to
extensions making calls at the Centrex level on prime lines, while other
services are provided by the communications system, acting as a switch
for calls between extensions and for calls that do not require Centrex
features.
In full Centrex service:
■ The communications system operates in Behind Switch mode.
■ Calls can be made between Centrex extensions at separate sites served
by the same Centrex.
