Requirements
When
you install the Octel Overture 200/300, adjust the levelers until the top of the cabinet is level, and
the cabinet does not rock. A bubble level is recommended for this purpose. No special tools are required
to adjust the leveling feet.
Distributor-Supplied Equipment
Each
Octel Overture 200/300 line card is connected to the PBX with a 25-pair cable. Supply one cable
for each line card. Make sure that the male/female connectors are long enough to reach between the Octel
Overture 200/300 and the PBX extension jack, without undue stretching or tension.
The Octel Overture 200/300 can be connected to punchdown blocks with a 25-pair cable and then be
jumpered to the PBX or Central Of
fice lines. The Octel Overture 200/300 can also use 25-pair cable to
connect to a breakout adapter that provides standard modular connectors.
A terminal, used for software installation and update, must be available at the customer site. During
installation, use an RS-232C cable to connect the terminal to the Octel Overture 200/300. This terminal
can be connected to the SP1 connector located in the front of the cabinet or at J1 in the rear of the
cabinet. If the terminal is to be permanently installed with the message server
, connect it to J1. If the
terminal is only used temporarily during installation and maintenance, connect it to SP1. A printer is
useful for making a hard copy of the software configuration.
