Key expansion modules

Up to two optional Meridian Key Expansion Modules (NT2K22XH) can be
used with the base CAP telephone. The keys in Figure 137 on page 528 show
the key expansion module with example labels for department or individual
names. These keys act as Direct Station Select (DSS) keys and Busy Lamp
Field arrays. Each of these keys is programmed with the Terminal Number
(TN) of the telephone to which it corresponds. To program these keys use
LD 11, explained later in this chapter.
You can use these keys to visually find out the status of a telephone, or to
contact and extend calls to telephones. The status of a telephone is indicated
by the key lamp in the following ways:
Idle — The key lamp is off.
Busy — The key lamp is steadily lit.
Forwarding — The key lamp is flashing.
