transformer
coupled
audio
output.
Check
the Messenger

the Messenger
must
be connected
to
any combination
of the APL RAN out-
put port or one or two CO line port(s).
When installfng
the Messenger
212 Plus unit
onto
the
4096
System,
both
the APL RAN
output
port and a CO Line port can be used
simultaneously.
However
connection
of the
Messenger
to these ports is different
For this
reason
each
type. of installation
will be de-
scribed
separately.
APL
RAN
Port
When the Messenger
2 12 Plus unit is installed
using
the APL RAN port the following
equip-
ment will be required.
-
An AF'L Board
(23VCSO12)
-
An Am
8 position
to 6 position
modular
line cord. (98ACT462)
1. To connect the Messenger
2 12 Plus to the
APL RAN jack plug the 6 position
end of
the ACT modular
line cord into the APL
RAN Port (APL MOD 3 jackl then plug the
