Description
Key number limits that can be assigned are as follows:
0-7 for Meridian Communications Adapter (MCA)
0 to 5 for M2006
0 to 7 for M2008
0 to 59 for M2616, varies with number of add-on
modules
0 to 79 for 2002P2, varies with value of KEM
0 to 79 for 2004P2, varies with value of KEM
The first IP Phone KEM is assigned keys 32 to 55, and the
second IP Phone KEM is assigned keys 56 to 79.
If either the Meridian Programmable Data Adapter (MPDA)
or the Display Module is equipped, then key 7 on sets
M2008, M2216, and M2616 and key 5 on set M2006
becomes Program keys which cannot be used as function
keys.
Any printout of the TN block does not show key 7 because
it is a local function key.
On the M2616, if CLS = HFA, key 15 on the voice TN
defaults to the Handsfree key. No other feature assignment
is accepted.
Primary and secondary data DNs must be unique.
A station SCR, SCN, MCR, or MCN DN must be removed
as a member from all Group Hunt lists before the DN can
be modified.
On the M3903, keys 4-15 are blocked. No feature
assignment is accepted for keys 2-15.
On the M3903, M3904, and M3905, keys 29-31 are
reserved. No feature assignment is accepted for keys
29-31 other than NUL.
On M3904, no feature assignment is accepted for keys
12-15.
