Meridian Programmable Data Adapter
When a Meridian Modular Telephone is equipped with the Meridian
Programmable Data Adapter (MPDA), you can make a data call using
keyboard dialing from your attached terminal. You can carry on voice and
data communication simultaneously without causing any mutual interference.
The MPDA communicates with Data Terminal Equipment (DTE) having
characteristics as shown in Table 57:
Note: The MPDA configuration of data parameters is stored locally
(although you can set the configuration in the Cabinet system system).
You cannot set the data parameters in the system before installing the
MPDA in the telephone (the configuration information will be lost).
The keyboard dialing routine may vary with the data equipment being used
and reference to the user's data terminal manual may be necessary. For more
detailed information, see Meridian Communications Unit User Guide and
Meridian Communications Adapter Reference Guide.
The MPDA can establish either data calls or voice calls. You can make data
calls using keyboard dialing, keypad dialing or the AT command dialing
feature. The AT dialing features lets you originate data calls to local and
remote Data Terminal Equipment (DTE) directly from a data terminal
