Modes of Operation
1
The system supports two modes of operation. The mode of operation determines how users
access outside lines from their telephones:
■
Key Mode. You access individual outside lines to make and receive calls.
■
Hybrid Mode. For Release 2.0 or later systems, you can access individual outside lines as in
Key mode. However, you also can create up to four groups, or pools, of multiple outside lines.
When you access a pool to make a call, the system selects an available line from the pool.
Since multiple lines are associated with the pool, you do not know which line within the pool is
being used to make the call.
System mode is determined by the configuration of the processor module. The system is factory-
set for Key mode. Changing to Hybrid mode requires a system programming change modifying the
processor module. For more information about programming the mode of operation, see
“Mode of
Operation (#198)” on page 4-50 .
The mode for your system must be decided upon before installation. In Key mode, no outside lines
can be pooled, and, in Hybrid mode, lines can be pooled and individual lines can be assigned
directly to line buttons.
Key Mode
1
When the system operates in Key mode, individual outside lines are assigned to users’ extensions
for making and receiving calls. At extensions with system telephones, each individual line (Line 1,
Line 2, Line 3, etc.) assigned to the extension is represented by its own line button. You can press
any of the available line buttons on a system telephone to make outside calls. (Single-line
telephone users must dial 9 at intercom dial tone to make an outside call since their telephones do
not have line buttons.)
With Key mode, you can easily join calls, since each line button can be labeled with a unique line
number. For example, if you want to join a call on Line 2, you simply press the line button labeled
“Line 2.” Key mode also lets you monitor call activity by using the lights next to the line button—
