Full Centrex Service
Limited Centrex
With Limited Centrex service users depend principally on the communications
system’s features, but a limited number of Prime Lines can be used to access
the CO Centrex. There are two cases that are particularly suitable for Limited
Centrex:
■ Centrex lines may be less expensive than other lines
■ Different users may have different needs for telephone service, such that
some users benefit more from Centrex while other users benefit more
from direct use of the communications system
