INTRODUCTION
Organization
The remainder of this manual is divided into nine main sections; tabs are provided for convenient
access to each section. All equipment descriptions are supported by illustrations.
GENERAL INFORMATION—Gives background data that applies to the entire range of
equipment covered in this manual.
EXPOSED PORT PROTECTION—Contains information on the protection required by
exposed ports. This section also lists some of the AT&T protection devices and gives
parameters that non-AT&T devices must meet.
AVAILABILITY—Lists the ordering status of the equipment covered in this manual.
ADJUNCT POWER—Lists the different terminals and adjuncts that require adjunct
power supplies and the recommended adjunct power supply. Information has also been
added about the MSP-1 power supply.
ADMINISTRATION—When some of the newer terminals are used with some older ver-
sions of the switches, the administration of the switch does not allow for the use of the
new terminals. These new terminals must be administered using the administration pro-
cedures of a similar older terminal. This is called aliasing. This section contains the
aliasing information and the appropriate caveats.
VOICE TERMINALS—Provides detailed coverage of the main groups of voice terminals,
divided into eleven tabbed subsections. This section contains detailed information on
each voice terminal that can be ordered as a component of DEFINITY Generic 1, Gen-
eric 2, or Generic 3, or possibly all three. It also contains brief descriptions of voice ter-
minals that were previously installed in earlier business communications systems. Check
each description to see if these voice terminals are compatible with DEFINITY G1, G2, or
G3, System 75, and System 85.
