M2000 Series Meridian Digital Telephones
Features keys
Each M2000 Series Meridian Digital Telephone has a number of
programmable keys with LCD indicators that can be assigned to any
combination of directory numbers and features (only one DN for the M2006).
The lower right-hand key (key 0) is reserved for the Primary DN.
Note 1: When equipped with a Display module, Meridian
Communications Adapter (MCA), or Meridian Programmable Data
Adapter (MPDA), key 07 is automatically assigned as the Program key
and cannot be changed. Key 05 becomes the Program key on the M2006
if equipped with the MCA or MPDA.
See "Data options" on page 85 for more information on the MCA and
MPDA.
Note 2: The M2006 is a single-line telephone and accepts only one DN.
The remaining five key/lamp pairs can be assigned any feature that is not
considered a DN, such as Transfer, Call Forward, or Conference.
Features that cannot be assigned are those that are considered DNs:
Voice Call and two-way Hot Line, for example. Attempting to assign
more than one DN to the M2006 causes the telephone to disable itself and
all LCDs light steadily. It will return to its normal operating state when
service change removes all secondary DNs.
LCD indicators support four key/LCD states:
Function
idle
active
ringing
hold
* An indicator fast flashes when you have pressed a feature key but have
not completed the procedure necessary to activate the feature.
Data Options
See "Data options" on page 85 for more information on the MPDA and MCA.
