Centrex Services
With each Centrex line, you have a set of Centrex services (some services may
not be available on all lines). Table 3-1 lists some of the most popular Centrex
services.
To complement your Centrex services, your equipment controller provides
additional features. You can use Table 3-1 to identify the services you have on
your Centrex system; then see Chapter 4 for more information on equipment
features you may want to add to your system.
Centrex services are supplied by your local telephone company; see the
Centrex documentation provided by your local telephone company for more
specific information on the services available with your system. Also, be aware
that the names of services may vary depending on the supplier. You can use the
System Planner to record the services available on each line in your system.
NOTE:
Many Centrex services are accessed by pressing the switchhook on a standard
phone, then dialing a Centrex feature code. On an MLS- or MLC-model phone,
however, use the Recall feature to send a timed switchhook flash and then dial
the Centrex feature code—see Chapter 5 for instructions on programming the
Recall feature on a button and Chapter 6 for instructions on using the Recall
feature. Pressing the switchhook on an MLS- or MLC-model phone disconnects
the current call instead of sending a switchhook flash.
