Data

For data calls, the power supply option is needed in addition to the power
from the loop.

Power supply board

The power supply option consists of a power supply board that mounts
inside the telephone set, coupled with an external wall-mount transformer or
closet power supply that provides power to the power supply board. The
power supply board connects to the telephone through a 14-pin,
bottom-entry connector and receives its power through pins 1 and 6 of the
line cord.
The power supply board comes factory-installed with any configuration of
the M2216-2 or M2016S sets. The M2006 set requires the power supply
board with the addition of any option. The M2008, M2008HF, and M2616
sets require the power supply board with data or an external alerter.

64k MCA +5V power boards

The 64k MCA has new circuitry to accept a +5V wall transformer available
soon from Nortel. The power board is replaced by a jumper and relay on the
Meridian digital terminal. All Meridian digital terminals with data ordered
have the jumper and relay already inside. The +5V transformer (A0655850)
will need to be ordered. The –48V transformer and power board can still be
used with this MCA. You will need to order the power board (NT2K10WD)
with the –48V, 110, or 220 transformer and install in the field.
