Meridian Programmable Data Adapter
The Meridian Programmable Data Adapter (MPDA) mounts within the
telephone (see Figure 36) and allows asynchronous ASCII terminals,
personal computers and printers to be connected to the telephone using an
RS-232-D (subminiature) interface. The MPDA has multilingual capability.
It requires additional power. See “Power requirements” on page 300.
For more information, see “Meridian Programmable Data Adapter” on
page 306
Program key
The Program key is automatically assigned to Meridian Modular Telephones
with Display or MPDA added. It allows you to change a variety of display
features such as screen format, contrast and language. It also lets you change
data parameters such as transmission speed and parity.
The upper right-hand key (key 05 on M2006, key 07 on all others)
automatically becomes the Program key when Display or MPDA is
configured with the telephone. The Program key is local to the set and shows
blank when you print key assignments in LD 20.
External Alerter Interface
The External Alerter Board provides an interface to standard remote ringing
devices, such as a ringing unit installed in a location separate from the
telephone. The External Alerter Interface is not the remote ringer itself, but
provides access to standard, off-the-shelf remote ringing devices. The Alerter
Board requires additional power (see “Power requirements” on page 300).
You can program the External Alerter Interface to activate a ringer (or light)
when the telephone rings or when the telephone is in use (off-hook).
Key Expansion Module
A modular 22 key unit can be attached to any 16 key Meridian Modular
Telephone. The extra keys can be assigned to any combination of lines and
features. You can add up to two expansion modules to a single telephone. You
will need a separate footstand for the module(s), one for a single module, one
for a double (see “Ordering information”). The expansion module requires
additional power (see “Power requirements”).
